An electric heater and a boiler are equally in demand today. How to install such equipment will be described in this article. With the help of such a device, you can cope with the problems of turning off hot water. Among other things, such installations can work on an ongoing basis. In a wide range in modern stores, you can find storage or flow-through electric boilers, the latter of which are less in demand, because they are inferior to storage ones in terms of volume and profitability. To install such a device, you can use the services of specialists or cope with the work yourself, but you will need to follow all safety rules. To do this, the electricity is completely turned off, and the hot water pipes are blocked.

Preparation of materials

If you decide to purchase such equipment, you should find out in advance. Of course, doing the work yourself is cheaper. If you refuse the services of professionals, then you should prepare a certain set of materials for installation. You will need either a safety valve, two flexible water hoses, and two dowel-nails. When buying a water hose, you should take into account that you will need two elements, each of which is 2 m long. However, the length will depend on the distance to the tie-in to the water supply system. When buying dowel-nails, it should be noted that there must be hooks at their ends. By the way, about the safety valve. It should be mentioned that it comes with an electric boiler. The valve must have a diameter of 10 mm.

Instrument preparation

So, you need a boiler. How to install such equipment, you should know even before you purchase it. Do you want to do the installation yourself? Good luck! However, it is worth considering that in some cases, if the work is carried out independently, the manufacturer's warranty will be canceled. In addition to materials, certain tools should be prepared, among them: screwdrivers, drills with a victorious tip for attaching to a brick wall, an adjustable wrench and a puncher. The latter can be replaced with an electric drill.

Installation instructions

Many home craftsmen, having learned how much it costs to install a boiler, prefer to do all the work on their own. This is not surprising, given that such services cost about 5,000 rubles. Do you have skills and do you know which side to approach the puncher and how to hold a screwdriver? Then why overpay? But if you do the installation yourself, you will have to prepare properly. Not the last role here is played by the reviews of those people who are not new to doing such a thing. If you study all the recommendations, you can come to the following.

The process should begin by choosing a place to mount in the bathroom or bathroom. Most often, such equipment is installed above the toilet, where it will not interfere with anyone. It is necessary to check the strength of the wall, as it will have to endure the load from the boiler. If there are unreinforced drywall partitions in the room, then you should refrain from installing the unit on them. With a boiler volume of 50 liters or more, a double load will fall on the wall, that is, 100 kg.

Before you install the boiler in the apartment, you should decide on the lowest point of the location of the equipment, marking it on the wall surface. Next, the master measures the distance from the mounting plate to the bottom point. The first is firmly welded to the body of the equipment. The resulting distance must be marked on the wall. The next step is to drill two holes. The craftsmen emphasize that you need to remember that the mounting plate does not have such holes; anchors with a hook at the end should cling to its edge.

So, everything is ready to mount the boiler on the wall. How to install it correctly? The question is by no means idle: the structure must be securely fastened, because the fall of such a massive device can cause injury. If the wall is made of concrete or brick, then for the work of the master it is recommended to use a puncher with a victorious drill. For a wooden wall, a conventional wood drill is used, the diameter of which is smaller than that of a plastic dowel. The latter must be installed in the hole and, if necessary, driven in.

The metal anchor is screwed in until it stops turning. As a rule, a depth of 12 cm is sufficient. The boiler should be hung by hooking the anchor hooks on the bar to fix it on the unit body. On this, the process of hanging the equipment can be considered completed. As you can see, the technology is not very complicated, so any home master can master it. At the next stage, you can connect the boiler to the water supply system, for this you should use flexible hoses.

We connect!

Judging by the reviews, polypropylene pipes can be used instead of flexible hoses, but it will cost more and take more time. There are two tubes at the bottom of the boiler, one of which has a blue plastic ring. Cold water will flow through it. The second tube is indicated in red and is intended for hot water outlet.

According to the craftsmen, in the place where cold water is supplied, a safety valve should be installed. It is usually supplied in the kit or purchased separately. The first step is to attach the relief valve. Do not forget to pre-wrap sanitary flax or sealing tape on the thread.

Masters advise at the next stage to screw one end of the flexible hose onto the safety valve. In this case, you must refuse to use the tape, since there is a rubber gasket in the hose nut that acts as a sealant. Well, the question of how to install a boiler in an apartment is practically solved. The next step is to screw one end of the flexible hose to the pipe from which the hot coolant comes. In this case, sealing tape is also not required.

Now you can start connecting the free ends of the hoses. The end to which cold water will flow should be connected to the water pipe. A valve or tap must first be installed at this place, which will, if necessary, shut off the fluid supply. Do not neglect this recommendation, as the boiler may fail during operation or require replacement of spare parts. The free end of the other hose must be connected to the pipe that goes to the faucet.

In principle, it is not difficult to install a water boiler on your own. You just need to arm yourself with certain knowledge (in addition to tools and materials). And there are many nuances in such a case. In particular, before connecting the unit, it is necessary to remove the tees on the water pipes. In the absence of certain experience, it is better to entrust this work to professionals. Now you can do the electrical part. If we are talking about Thermex brand water heaters, then they have one feature, which is the presence of a cable for connection along with a plug in the kit. Moreover, this element is connected to the boiler. If this is not the case, then consumables will have to be purchased separately.

And further. In order for everything to go without a hitch without a hitch (read - without accidents), the masters strongly recommend observing safety precautions when working with electricity.

What else needs to be considered when carrying out work

If you are faced with the question of how to properly install the boiler, then you should know that you do not have to open the lid if everything is already connected in the equipment. It is enough to install a grounded socket in advance, which should be located near the equipment. You should turn on the cold water tap to check how tight and secure the connection is. If there are no leaks, the boiler plug can be connected to the outlet. Now you know how to install. If you did everything correctly, then the indicator on the case should light up. After that, you can set a certain temperature using the regulator, which is usually located at the bottom.

Conclusion

It is important to remember the main mistakes that are made when connecting the equipment described in the article. In particular, before installing a boiler in the bathroom, the masters recommend taking care of the presence of a circulation system. This will minimize energy losses if hot water is constantly in the pipes.

Dacha has long ceased to be a place for a person to grow vegetables and fruits. More and more people seek to relax outside the city in summer cottages.

Some move to the dacha permanently or for the spring-summer period. And, of course, everyone wants to relax and live in the country in comfortable conditions, without depriving themselves of the usual amenities that are in a comfortable apartment. And the lack of hot water can, and at all, spoil the whole rest.

The problem with hot water in the country is quite easy to solve - for this you need to install a water heater. In stores you can find a lot of devices that heat water from the electrical network. You can read more about the types of water heaters in the article.

In order for the heater to work for a long time and efficiently, it must be properly connected to the network and water supply. The next article will tell you how to do this.

Choosing a place to install a water heater

Before installing a water heater, you need to decide where to do it. Here are a few factors to consider when choosing a location:

• The load-bearing wall must be strong and resistant. Even if the water heater is small in volume, its weight is quite large. Therefore, it is necessary to take care, if necessary, of strengthening the wall or additional support.
• water heater dimensions. It is necessary to measure in advance the place where it is planned to install the water heater, so as not to miscalculate with the dimensions.
• if space permits, you can pre-allocate one room for the boiler room.
• What type of water heater will be installed. A gas water heater requires certain communications. For example, an air outlet.

When installing, it should also be remembered that the sockets into which the heater will be turned on must be isolated from water ingress.

Water heater connection diagrams

Not all summer cottages have water pipes. Many summer residents do not have the opportunity to bring water supply to the dacha. What should they do in this case?

There is a way out of this situation. Many owners of country houses, deprived of centralized water supply, use water storage tanks. Most often, these containers are installed on roofs. Owners of such storage tanks also have the opportunity to use water heaters.

Thus, depending on the type of water supply, there may be several schemes for connecting a water heater.

To the water container

The main rule for connecting a water heater to a water tank is that the distance between them must be more than 2 meters.

If the distance between the tank and the boiler is less than 2 meters, a slightly different water heater connection scheme will be applied.

Another nuance that should be taken into account when connecting the boiler is that the pressure must be less than 6 bar. In the case when the pressure is greater, it is necessary to install a reducer that will reduce the pressure. The gearbox is placed in front of the water heater. This must be done, as the gearbox will protect the water heater from damage.

To the water supply

Connecting the boiler to the water supply is a simple task. To do this, you need to have at least some idea of ​​how the plumbing system works.

Before connecting the boiler to the water supply, you need to hang it on the wall. To do this, you need strong large fasteners. They rarely come with water heaters, so you need to take care of the fasteners in advance.

After you have hung the water heater on the wall, you can start connecting it to the water supply. The diagram below shows how to connect the heater.

If the water leaves much to be desired, you need to install a filter in front of the heater. This will extend its service life.

In the absence of grounding, a water heater cannot be installed.

What is required to connect?

In order to connect the water heater to the water supply system, you will need to stock up on a set of necessary tools and materials. During the installation process you will need:

• pipes of the required diameter;
• tees for pipes;
• shut-off valves;
• sealant for plumbing work;
• flexible hoses;
• pipe cutter - manual or electric;
• soldering iron;
• several keys of different sizes.

We take into account the type of plumbing

The method of connecting the boiler to the water supply largely depends on the type of water supply. We will consider several installation options - for polypropylene, metal and metal-plastic pipes.

polypropylene

To ensure a reliable connection of pipes made of polypropylene, you need to use special end couplings and turns. In this case, it is better to choose stabilized pipes, that is, additionally reinforced with another layer (most often this is aluminum foil).

Metal

When it comes to metal plumbing, we usually mean steel pipes. It is more difficult to connect to such pipes - this is due, first of all, to the characteristics of the material. For a more reliable connection, you should use a special clamp that can withstand a large load. The clamp must have a so-called "tie-in" (special pipe).

The boiler is connected to a metal water pipe in the following sequence:

• prepare the junction (tie-in): remove dirt and paint residues;
• install a clamp on the main pipe, placing a sealing gasket under it;
• armed with a drill, we drill a hole in the pipe passing through the pipe (at the same time, we adjust the diameter of the hole to the diameter of the sleeve);
• we apply the thread and install the drives on it (threaded connecting elements);
• we mount cranes in place;
• we attach pipes to the taps, which we then connect to the device.

metal-plastic

Metal-plastic is the most modern of all the above materials. It is lightweight and durable, making it very easy to use. Another important advantage of metal-plastic pipes is the convenience of the installation method: installation is carried out in the open.

The main stages of connection:

• cut the pipe
• install tees on it;
• we make taps to the water heater;
• connect the pipes to the device.

We install shutoff valves

An important step in connecting any type of water heater to the water supply is the installation of devices designed to shut off the flow of water. The installation of such fittings for pipes with hot and cold water has its own characteristics.

For cold water supply

Electrical connection

To begin with, we want to introduce you to the basic rules for connecting a water heater to an electrical network. Compliance with these recommendations will allow the installation to be carried out as safely and efficiently as possible.

• The socket for the boiler must be located in a place inaccessible to water splashes. Experts strongly advise using special waterproof sockets for these purposes.
• The water heater can only be turned on when the ground is connected to the electrical outlet. This can be done using a three-wire wire (in this case, the socket must also be designed for three poles).

Connections of electrical wires must be made outside of a room with a high level of humidity. If we are talking about the kitchen and not the bathroom, this rule can be ignored.

After making sure that all safety rules are observed, you can proceed directly to work. The procedure will be like this:

• we measure the distance between the installation site of the water heater and the outlet;
• we disassemble the plug of the device into elements;
• remove the insulating material from the cable;
• we clean the veins with the help of side cutters;
• armed with a soldering iron, we connect the wires with the plug contacts (red - to the phase, yellow / green / black - to the ground; blue - to zero);
• remove the water heater panel and open the contacts;
• we clean the cores at the opposite end of the cable;
• we connect them to the contacts of the device and return the panel to its place.

You can connect to the mains in another way - connect the water heater directly to the shield. In this case, you need to act as follows:

• we lay the cable from the device to the electrical panel;
• we install an automatic machine near the water heater;
• we pass the cable through the machine;
• remove about 100 mm of insulating material from the cable;
• we expose the phase from the machine;
• we connect the phase from the machine to the upper terminal, and from the water heater to the lower terminal;
• remove the insulating material at both ends of the cable, release the cores;
• remove the cover of the boiler, connect the wires to the terminal of the device;
• turn off the power supply and connect the heater to the electrical panel.

The following video shows the water heater connection diagrams and their descriptions, which will help you figure out how to connect the boiler correctly.

A water heater, also known as a boiler, or an autonomous heating device, in some cases is the most successful solution to the problem of hot water supply. It is also used in those houses and apartments where there is no hot water at all, where there is, but intermittently, but most often those who want to save money think about how to connect the boiler to the water supply.

We will give the calculations using the example of Moscow (knowing about the tariffs in your region, you can also calculate the economic benefit). On average, a family of 4 consumes 8 cubic meters of hot water per month. The tariff for hot water in 2016 is 108.41 rubles. (population). It turns out that you will have to pay 867.28 rubles per month for hot water supply.

Now for the water heater. For a family of 4 we take a 100-liter storage boiler 2 kW. Such a device heats water to the required temperature in an average of 2.5-3 hours, for a total of 6 kW per day, 180 kW per day. With a tariff of 3.52 rubles. the total amount of the payment is 633.6 rubles. As you can see, 25% cheaper.

If we take into account the most economical - instantaneous water heater 5 kW, the tariff will be 75% cheaper than hot water supply. Its average productivity is 2 l / min. It will take 25 minutes (0.42 hours) to heat 50 liters. 0.42 x 5 = 2.1 kW per day. In a month it turns out 63 kW. In monetary terms, 222 rubles.

Since the economic benefit, as they say, is obvious, it's time to tell you how to properly connect the boiler to the central water supply.

Varieties

To date, the range of water heaters is very extensive. The differences are in the heating method, power, tank shape, installation method, etc.

Water heating method:

• electric;
• gas;
• combined (gas/electricity);
• indirect heating of water by means of a boiler.

Water supply method:

• pressure;
• non-pressure.

Installation method:

• outdoor option;
• horizontal and vertical hanging.

External tank shape:

• round (cylinder);
• oval (rectangle with rounded corners).

Device

• outer casing;
• internal tank;
• heat-insulating protection from polyurethane;
• tubular electric heater (TEN);
• thermometer;
• thermostat.

This type of water heater is called storage due to the presence of a tank filled with water. The heating element heats the water to a certain temperature, and the thermal insulation between the inner and outer casings keeps the temperature. As needed, water is consumed, collected automatically again and heated again.

Flow unit device

In a flow boiler, due to the operation of a more powerful heating element, the water passing through it warms up instantly. The temperature is controlled by decreasing or increasing the flow.

Such devices are mounted directly at the point of the plumbing system, but only at one point - it is impossible to get hot water from one flow boiler in both the kitchen and the bathroom at the same time.

The easiest to connect and operate is an electric boiler, since it does not require approval, special permission and the purchase of additional tools.

A flow-through HV is a very powerful household appliance that requires 30 A wiring and mandatory grounding to connect. In order to limit damage to the line on instantaneous water heaters with a heating element power of more than 5 kW, the set does not include a power cord and a standard plug.

The storage HP has a standard power of 2 kW, where the supply current is 10 A. The usual "home" wiring is quite enough for the operation of this unit.

Considering that PV does not provide the most hot water, precisely due to instant warm-up, many opt for accumulative ones. Moreover, almost everyone can connect it.

How to connect correctly

Preparatory actions

1. Site preparation based on “walking” accessibility to connecting elements - water supply pipes and a socket.
2. The wall on which the hinged boiler will be mounted must be strong - the total mass of the device in 100 liters will be 130-150 kg, depending on the internal structure.

Necessary tools and materials:

• set of wrenches;
• roulette;
• mounting level:
• perforator (for a load-bearing wall) or drill;
• pliers;
• connecting tees-fittings;
• stopcocks (on inlet pipes);
• sealant (tow, paste, tape, etc.).

Installation process

Canopy of the boiler on the wall. Depending on the volume of the tank, choose the appropriate number of brackets (they are usually included) and dowels. For a standard HV with a volume of 100 liters, 2 complete brackets are enough. If the volume is less - 2 is also required, if more - 4/6.

On the reverse side, see how many holes are on the boiler. Respectively. so many brackets will need to be purchased if they are not included.

Measure the distance between the holes and make marks on the wall where you will make holes (standard 180 mm). If the wall on which the device will be hung is load-bearing or in a panel house, then a puncher will be needed. In other cases, an electric drill will cope with this.

Be sure to check the straightness with the mounting level. The device must be installed absolutely level without distortion.

We drilled holes, inserted dowels and fasten the brackets with screws, after which you hang the boiler on hooks.

How to connect the boiler to the water supply

To begin with, it should be noted that the water coming from the water supply system does not have a high degree of purity. In order to clean the heater less often, it is recommended to embed a small filter on the inlet pipe.

Now we connect the HV to a pipe with cold water, for this we screw a safety valve onto the pipe of the device itself with a blue ring and isolate it with FUM tape. After that, we connect the branch pipe with the red ring to the outlet pipe, through which hot water will flow to the mixer. We also isolate with FUM tape.

For reference. FUM-tape is an insulating material on a fluoroplastic base, which has high functional properties. The tape does not deform when the temperature changes, does not rot, does not wear out, does not tear, is labile to chemical elements, and is not toxic.

In order for the thread to “sit down” as tightly as possible, it is necessary to wind the tape strictly clockwise.

Pipe connection

Polypropylene pipes

What tools will be needed:

• pipe cutter

• tees and couplings (MPH)

• stopcock

How to connect correctly:

1. Shut off hot and cold water pipes on the riser.
2. Make an incision at the marked place on the pipe and solder the tees on both pipes.
3. Insert additional pipes into the tees (for extension).
4. Mount the couplings on the outlets and connect stopcocks to them.
5. Depending on the remoteness of the boiler, connect stopcocks to each of the pipes or lay an additional flexible hose and connect to them.

In the photo you can see how the connected device should look like.

If the pipes are built into the wall, the connection will be somewhat more difficult.

1. Break the coating directly over each pipe.
2. You cut the pipe in the marked place and insert the repair sleeve, more often it is called an American.
3. Weld the coupling to the tee from the polypropylene side, and to the cut on the pipe - with a threaded end.
4. Remove the coupling and connect the pipes as indicated earlier.

Metal-plastic pipes

All fastenings on such pipes are carried out by means of fittings.

Procedure.

1. Shut off the water at the stand.
2. Cut the pipes with a pipe cutter in the marked place.
3. Insert a tee, connect segments of a metal-plastic pipe or a flexible hose to the outlet and connect it with fittings to branch pipes.

Steel pipes

For reference. This is a clamp with a side threaded branch that allows you to make a hole in the pipe without special equipment.

In order to install it, it is necessary to clean the pipe from paint and spraying, put a rubber seal and fasten the clamp. This results in a completely sealed connection. Next, drill a hole through the branch (the sleeve is included) and connect the stopcock, and already to it a flexible hose for connecting to the water heater pipe.

How to connect a flow unit

PV is installed exclusively on the hot water pipe.

Procedure

1. Turn off the water at the stand
2. Cut the pipe in the place where the connection will be, and weld shut-off valves on both sides.
3. Connect the outlet and inlet pipes with stopcocks using flexible hoses.
4. Connect to electricity.

Using such a device in everyday life, first turn on the water, then the boiler turns on. At the end - first the boiler, then the water.

To understand exactly how to perform actions correctly and in what order, watch the training video

Video - how to connect the boiler to the water supply

This article will probably be more useful to residents of high-rise buildings than residents living in private homes. Although, if there is no gas connected to the house, or it is a country house, then the storage water heater will be just what you need.

In urban apartments, hot water supply is turned off twice a year: in the fall before the heating season and in the spring after the heating season. Each outage lasts an average of 2 to 4 weeks. So it turns out that a city dweller for a year about a month or two washes in a basin. It's good who has a bath, and who has a shower ...

1. Choosing a storage water heater.

First of all, we determine the volume of the tank.
30 liters is enough for our family of three. True, it also happens that if someone decides to warm up a little and uses more water than they should, then the rest have to wait about 20-30 minutes until the next 30 liters are heated up.

Now we choose the design, and in what design the water heater will be: vertical or horizontal, flat or round, elongated or square, classic white or any other suitable color.

But, again, in order to choose the design and execution, you need to decide on the installation location of the tank. Typically, a water heater is installed in the toilet above the toilet. However, if you have a combined bathroom, then place the tank so that it fits into the design of the bathroom, does not take up the necessary space and does not interfere.

2. Installation.

Installation is simple and does not take much time.
Here you will need a hammer drill - if concrete, or an impact drill - if brick.
Drill or drill with a diameter of 10 mm, and two anchor bolts.
We make markings, drill, drive the anchors and hang the water heater.

3. Connecting the water heater to the water supply.

We will consider two connection schemes: the first is when you make repairs, and the water heater is initially installed permanently. The second is when repairs will only be or are not expected in the near future, but you want hot water. By the way, according to the second scheme, my tank worked for almost 6 years, until finally a repair was made.

In general, the water heater connection diagram is very, very simple.
It is connected in parallel to the domestic water supply system: the inlet to the cold water pipe, and the outlet to the hot pipe.

Let's take a look at the diagram.
When to the apartment hot water comes in- No water heater required. It is cut off from the apartment water supply system with valves №3 and №4 , that is, in normal mode, these valves are closed. Cold and hot water circulates through the pipes as it should be.

Now consider the scheme when the central water supply is turned off and hot water not received to the apartment.

We turn on the water heater.
For this close inlet valve №1 on hot water and open valve №3 and №4 . We supply 220 Volt power to the water heater, and wait about 40 - 50 minutes (depending on the capacity of the water heater) until the water in the tank heats up to the set temperature. Once the water has warmed up, use it as usual.

As hot water is used, the same amount of cold water enters the tank, where cold and hot water are mixed. When the amount of cold water exceeds the amount of hot water, the water in the tank will become warm, and you will have to wait a little for it to heat up.

Now consider temporary water heater installation diagram.
In this case, we need: 2 tees, 2 flexible hoses for connecting water, a fum tape and a plug with a cord. Cord enough to reach the nearest outlet.

First of all, we determine the place of installation of the water heater. It can be mounted on the wall, or you can just put it on the floor, or put it away somewhere.
When we have decided on the installation site, we measure the length from the water heater fittings to the nearest mixer. We purchase two flexible hoses of approximately the same length.

We remove the mixer and screw the tees in its place.

Wrap all threaded connections with fum tape.
Do no more than 3 turns.

Now we install the mixer in place, but already in a tee. Well, we screw the hose from the water heater into the upper part of the tee. As you can see, everything is simple.

Advice. First, assemble the connection diagram to the tee in the store, so that later you don’t run and change the part that doesn’t fit.

When hot water is given, and if the tank bothers you, it can be turned off and removed until the next time. And in the vacant place in the tee, screw the plug.

More to be said about safety valve that comes with the tank. On the diagrams, it is indicated under №5 . This is such a necessary element, without which it is impossible for the water heater to work.

As we know, water expands when heated. And since water is an incompressible medium, when heated, the water will expand, thereby creating pressure on the walls of the tank, as well as on the inlet and outlet pipes. The water has to go somewhere.

So, if there was no safety valve, then when a certain excess pressure was reached, the water would simply break the tank. When there is a valve, the maximum allowable pressure created by water is released through this valve.
The safety valve itself is set to a certain maximum pressure, upon reaching which it works. Therefore, if you notice that water is dripping from the valve - do not be alarmed, this means that it is dumping excess.

4. Supply voltage to the water heater.

For a water heater, it is desirable to stretch a separate power line of 220 volts.

The figure shows part of the access shield of high-rise buildings of the old building (copied from my own). In the driveway or in your shield are added: RCD - QF2, circuit breaker - SF1 and zero block N1.

Remember. Zero block N1 is in no way connected with a common zero.

The following figure shows a diagram with zeroing. That is, you zero on the body of the access shield, thereby forming third conductor necessary for the correct operation of the RCD.

These two water heater connection schemes are used in old high-rise buildings (system TN-C). But which one to use you decide. I personally have not installed an RCD, although I am thinking about it, but I have not yet decided on the circuit.

Be sure to read the articles: and. And only after reading these articles, choose according to which scheme you will connect the water heater.

Well, the electrical circuit for houses of modern construction (system TN-S). Perfect connection. Here, too, I think everything is clear.

Yes, I almost forgot. The supply cable is led directly from the shield to the water heater, and does not start into any junction boxes.

Now you can easily install and connect water heater to the domestic water supply system, as well as supply a 220 volt supply voltage to it.
Good luck!

The boiler in many cases acts as an indispensable equipment built into the water supply system. Its installation is advisable in two cases: if there is only a cold water supply and if there is hot water, which is supplied irregularly.

Often there is a situation when installing a boiler is a more profitable way to provide hot water than using a central hot water supply. In many settlements, water tariffs are very high, which leads to a similar situation.

Water heater installed in the apartment

There are a wide variety of water heaters on the market today. The main indicator by which you should make a choice is the type of device. Allocate storage and flow boilers. The first type has the form of a large tank in which a heating element is installed. This allows you to provide a significant amount of hot water.

As it is used up, the tank is replenished and heated. However, if the water is completely used up, then heating the new one will take some time. The flow boiler is smaller. The question of how to connect the boiler to the water supply is simpler for him - the device is placed on the pipe and works immediately after the tap is opened.

Another parameter by which devices can be classified is the heat source. Most boilers run on electricity, it is easier and safer. However, the cost of energy can be high. Gas equipment is more difficult to install, however, its cost of operation is lower. Certified professionals are required for the installation of a gas heating device. This is the only way to obtain an operating permit, which is issued by the state organization that supplies gas.

You can also connect a hot water boiler yourself, since the device works in the same way as a conventional electric kettle. It is more difficult to integrate the boiler into the plumbing system. And if for flow devices this usually does not cause problems, then when installing storage boilers, follow the instructions.

Wiring diagram for an electric storage boiler

Before you directly connect the boiler to the water supply system, you should perform the following actions:

Scheme of connecting the storage water heater

• Choose an installation location . It is recommended to choose a place where access to the connecting elements will be provided. They break down quite often and periodically need maintenance, so easy access to them will facilitate many of the work during operation.
• Find a solid foundation . A household boiler can weigh more than 100 kg. The wall on which the boiler will be mounted must be strong enough. Otherwise, a supporting structure will be required.
• Proximity of water pipes . If they are nearby, then this will simplify installation. Otherwise, there is a need for additional pipeline.

The electric boiler is equipped with a heating element. To ensure fast heating, it usually has a large power. Therefore, you should think about the electrical connection in advance.. It is necessary to calculate what section of the wire will be required to provide the device with energy.

In the question of how to properly connect the boiler to the water supply, the work should be carried out in the following sequence:

• Check valve installation.
• Check valve installation.
• Installation of the outgoing system.

The algorithm depends on the pipe material - plastic or steel. It is much easier to join plastic pipes. To work with plastic pipes, you will need a soldering device. Joining steel pipes often requires welding. In plastic pipes, installation is carried out using tees and couplings. Metal-plastic pipes are connected by fittings.

Connection to steel pipes can be made without welding. For this, a tee is used, popularly called "vampire". It is a wide collar, the side of which has a threaded pipe. The tee is fastened to a clean pipe surface. The connection is sealed with rubber pads and fixed with screws. After that, a hole is drilled in the pipe. A stopcock with a flexible hose is screwed into the pipe.

Installation of a flowing electric boiler

For the question of how to connect an instantaneous water heater, there is the following instruction:

Flow water heater connection diagram

1. Shutdown of water supply.
2. Making a cut in the required location of the pipeline.
3. Installation of shutoff valves. This allows the boiler to be dismantled for maintenance or repair without shutting off the water supply.
4. Connecting the inlet and outlet pipes of the heater with shut-off valves using flexible hoses.

Conclusion

Since there are many boilers of various designs on the modern market, it is rather difficult to write a universal installation scheme.

The most important point of the instruction is the need for grounding. Unfortunately, this point is often ignored. Water and electricity are a dangerous combination. To protect yourself from electric shock, you must carefully follow the requirements in the instructions. In addition to grounding, a residual current device is often required.

How to connect a water heater to the water supply - an overview of options

To solve the problem with hot water, not only in the house in the country, but also in the apartment - the installation of a water heater will help.

Currently, manufacturers offer several types of different water heaters, each of which can be installed both in a country house and in an apartment in a bathroom.

As a rule, the most commonly used electric water heater today is either storage type or instantaneous.

Both types of devices have specific features in their work, but in any case, each unit, if connected correctly, can supply hot water to the faucet and shower at the same time.

The operation scheme of any type of electric water heater is based on the conversion of current energy into thermal energy, which means that both the storage and the flow devices must have a heating element.

In any case, if you have a connection diagram at hand, then all the required tools and consumables, installation of any type of heater in a country house or in an apartment in a bathroom can be done by hand.

How to install a water heater in the bathroom to simultaneously supply hot water to the faucet and shower is described in the video posted in our article.

Mounting and installation features

Installation of both storage and flow types of heaters, with the right approach to business, can be done by hand both in the bathroom in the apartment and in the country house.

Of course, in order to do all the work correctly, you must have minimal plumbing skills and know the principle of operation of the selected water heater.

When installing the unit, you should not rush, as you can miss any detail, as a result of which there is a risk that the connection diagram will be broken and the device will not work correctly.

Do-it-yourself installation of a water heater will save significant funds on calling a master and will provide an opportunity to gain experience in performing this type of work.

The installation of a water heater, regardless of its type, is carried out according to certain rules, taking into account safety standards.

Before you start installing a water heating device in a bathroom in an apartment or in a country house, you need to think through every little thing.

You should choose the right place where it will be located.

The device itself must be freely accessible not only at the time of its installation, but also during the entire period of subsequent operation.

In addition, you should pay attention to the surface of the wall on which the device itself will be placed. It must freely support the weight of the device and have a flat surface.

You should also pay attention to the condition of the wiring. For an electric type water heater, the quality and condition of the wires plays an important role and is the key to safe operation.

In addition, it is necessary to check the condition of all pipes and risers in the apartment or in the country and, if necessary, replace them.

At hand should be a diagram of the entire connection, which should also indicate the piping for the shower and faucet.

Device selection

Currently, specialized stores offer a huge selection of water heaters of various types, but a person is arranged in such a way that he is always looking for a device that will be of high quality and affordable price at the same time.

In this case, Termex brand units, which are presented in a wide range, will be an excellent choice.

Termex accumulative type devices are distinguished not only by their ease of installation, but also by their reliable design. Termex can be easily installed both in the bathroom in the apartment and in the house in the country.

In addition, the installation of Termex implies the simultaneous supply of hot water to both the shower and the tap in the bathroom.

The water heater of this brand has a special safety valve that protects it from various malfunctions.

Under the Termex brand, water heaters and flow type are produced. These devices are also made only from high-quality components, which guarantees their long service life.

The scheme of operation of the Termex flow type water heater involves the simultaneous supply of water to the shower and faucet when installed in the bathroom.

In addition, the special safety valve installed on the Termex flow device allows you not to worry about its safety.

A distinctive feature of all types of Termex brand water heaters is that their installation does not take much time and can be done by hand.

In any case, when choosing a water heater for an apartment or a house in the country, you should, first of all, pay attention to both the quality of its performance and its appearance.

You should also take an interest in the operating conditions, since the convenience of using the unit in the future largely depends on this.

Installing a flow heater

Flow type water heaters have one characteristic feature, namely, compact dimensions, which allows them to be installed directly under the sink in the kitchen or bathroom.

The heating of the liquid in them occurs in a special metal flask, in which sufficiently powerful heaters are placed.

In view of this, when installing this type of water heaters, it is necessary that the wiring in the country house or in the apartment be in good condition and be able to withstand heavy loads.

It is best to install a separate machine for this water heater, to which to lead a wire with a large cross section.

After the problems with the supply of electricity are solved, you can proceed to the installation of the device itself.

How to connect a water heater: step by step instructions

It can be installed either according to a temporary scheme, or according to a stationary one.

In the first case, it is necessary to insert a special tee into a pipe with cold water and connect it to the device itself through an additional valve.

After that, it remains only to apply voltage to the water heater and open the tap for hot water.

Meanwhile, a stationary installation implies the necessary supply and intake of liquid in pipes parallel to the general plumbing system.

In order to install in this way, it will be necessary to cut tees into the pipes, directly under cold and hot water. Next, shut-off valves are hermetically installed.

This can be done with a fum tape or ordinary tow. After that, it is necessary to connect the inlet pipe of the water heater to the pipe that is responsible for supplying cold liquid.

Then the outlet pipe with a tap is connected, which is responsible for supplying hot water.

If everything works properly, then electricity can be supplied to the water heater, after which hot water should flow from the corresponding tap.

To increase the safety of the entire system, it is recommended to install a safety valve together with the water heater.

How the instantaneous water heater is installed is described in more detail in the video above.

When installing storage-type water heaters, the requirements for electrical wiring are not as strict as those for flow-through ones. In addition, the cost of such devices is much lower.

It should also be noted that a scheme is quite common in which this water heater simultaneously provides water supply to both the shower and the faucet, which explains their popularity.

Installing such a water heater correctly, with all the necessary material and tools, everyone can, and in a fairly short period of time.

First you need to check the condition of the electrical wiring and plumbing system in the apartment, and if there are any malfunctions, they must be eliminated.

Then the water heater itself is fixed on the wall, as shown in the video below, after which it will be necessary to bring not only pipes with wires, but also mount a safety valve.

After the water heater is installed, it is connected to the plumbing system, and a safety valve is also connected.

The subsequent installation consists in the fact that pipes are connected to the corresponding inlets and outlets on the device through a safety valve.

To begin with, the cold pipe is installed and connected, while the safety valve must be in the closed position.

If the installation of any water heater was performed correctly, then hot water will flow from the corresponding tap, while all connections and pipes will be in a sealed state, and the wires will not overheat.

How to install a water heater with your own hands, you can learn in detail on the video, which is posted in our article.

How to install a storage water heater?

Let's figure it out with our own hands on the example of only one model. The sequence of installation of wall-mounted storage water heaters is the same, regardless of model or manufacturer.

Where is the best place to install a storage water heater?

It is easier to answer: where you should not install a water heater.

For example, it is not recommended to hang it over a bathtub or shower, because it is not recommended to splash water on the electrical part of the boiler. If there is not much free space in the bathroom, then you can install a water heater above the washing machine or toilet.

What tools and materials are needed to install a water heater?

To install the water heater, you need hooks with dowels (for suspension), an adjustable wrench, winding (linen) with Unipak paste, corner taps, a tape measure, a pencil (marker), a puncher or an impact drill (depending on the material of the walls), a drill of the appropriate diameter.

Installing a storage water heater

Installation begins with measuring the distance between the fasteners on the boiler itself. Mounts are two brackets on the back of the case at the top. We need two sizes: 1) the distance from the top of the water heater to the bottom of these brackets; 2) the distance between the middle of the brackets. The first size is needed so as not to make the canopies too close to the ceiling - so that the boiler cannot be hung. The second dimension is the distance between the hooks on which the boiler will hang.

We also add to the first size how much it is not a pity, for example, 50 mm, so that the water heater is not close to the ceiling. And we mark the resulting size on the wall from the ceiling in the selected place.

We first draw an center line on the wall, and from it to the left and right in half of the second size. By level, we check that these two marks are on the same horizontal line, otherwise the boiler will hang crookedly:

After marking, you can drill. Remember to make sure that there are no electrical wires running through the drilling points.

drilled; we hammered plastic dowels into the holes and screw the hooks into them:

We screw it in not completely, but leaving a gap of ~ 10 mm between the hooks and the wall - so that you can hang the boiler.

Boiler hung up

A non-return valve, also called a safety valve, is screwed onto the cold supply:

The valve is included with all water heaters. It is needed to protect the water heater from excess pressure that occurs when water expands when it is heated.

Do-it-yourself storage water heater connection

I repeat: a safety valve is installed on the cold water supply pipeline.

Please note: there is an arrow on the valve body indicating the direction of water flow.

A few words about why to put a valve if there is a thermostat in the boiler itself. But if the thermostat does not work, and the water begins to boil, the pressure in the system rises, then the safety valve “takes on”: it opens and releases excess pressure.

Attention! Valves are designed for a certain pressure, which must be taken into account: if the valve is designed for pressure less than in your system, then it will work constantly.

And finally, we connect the water heater to the outlets of the water pipes, on which there should be taps:

It is clear that the pipe outlets must be made in advance, at the design stage, having determined where the water heater will be installed and where the pipes will be connected to it.

Features of outlets for the boiler

The socket must be installed in the bathroom with a protective cover. And the outlet for the boiler must have its own automatic switch - so that each time you don’t pull the outlet, but turn it off with a switch (before taking a shower or bath, the boiler must be turned off so as not to get an electric shock through humid air).

Filling the water heater with water and turning it on after installation

To fill the boiler with water, slightly open the tap with cold water (the tap that is for the boiler, and not anyhow).

Important! The boiler does not need to be plugged into the outlet yet!

Then we open the hot tap on the shower or bath faucet and ... nothing should come out of it. We open the hot water supply from the water heater and wait for water to flow from the shower faucet.

It is clear that when the water heater is first filled, the water will not be hot (I remind you: the boiler has not yet been connected to the outlet!), The task now is to make sure that the water is moving through the pipelines properly. It is advisable to remove the grids on the shower mixer so that the debris that is likely to come out of the pipes and not clog these grids.

While the boiler is filling, let's see if there are any leaks. If available, tighten the connections.

The water from the shower faucet went - excellent. The boiler is full. We return the mesh to the mixer tap.

The queue for the inclusion of the boiler in the network. We set the relay-regulator to zero. Plug the boiler into an outlet. Set the temperature. How to set the water temperature for a specific water heater model, it is better to read in the passport for this particular model, and not on Internet sites.

That's all about it how to install storage water heater.

P. S. This completes the step-by-step instructions for arranging water supply and sewerage with your own hands. I'm glad it helped you.

How to check the water heater heater

Water heaters today are not a luxury, but one of the most necessary devices that saves during periods of water shutdown and lack of hot water, as well as during difficult times of repair work, which, unfortunately, happens quite often. However, the water heater will be able to work for a long time and uninterruptedly only if you take care of it and treat it carefully - clean it in time, monitor the safety of its parts, ask yourself in a timely manner “how to check the water heater heater?” and correct it if it is defective.

Studying the design of the water heater will allow you to carry out repair work on your own, without resorting to the help of specialists, since knowledge of the design allows you to determine the faulty element and have an idea about the procedure for replacing or repairing it. Moreover, the work of this type of work is not so difficult, since water heaters have a fairly simple design: (See also: How to change the TEN in a water heater)

1. The body is the main part of the device. This is the largest component of the water heater, which includes all the others;
2. The heat-insulating layer allows you to protect the unit from heat loss;
3. The tank is another important detail. It is designed to heat incoming cold water;
4. Hot water intake tube;
5. Magnesium anode protects internal elements from corrosion and its destructive effect;
6. TEN is another important element with which water is heated. Not much different from teapot ten;
7. The cold intake pipe supplies cold water;
8. Sensors, which are represented by a thermostat, thermostat and thermal switch. These elements are the only technological representatives in such a device. These parts are responsible for the safety of the entire device, and also contribute to the automatic implementation of heating, as well as independent shutdown;

(See also: How to replace the heating element in the boiler with your own hands)

9. The control panel is a necessary element of any device. In this case, it is a set of indicators that indicate a particular state of the water heater, a mode switching panel, and a thermostat controller.



Electric water heaters with dry heat, like other others, have the same principle of operation, due to the simplicity of their design. Opening the cold water supply starts the process of filling the internal container - the tank. The unit is connected to the network only after the air is bled, which is carried out by means of a hot water intake.

After switching on, the sensors record the temperature of cold water, after which the signal enters the heating element and the circuit closes. From this moment, the incoming water begins the heating procedure. Thanks to a controlled thermostat, the user can set any temperature up to which the device will heat up. After the completion of the heating process, the heating element turns off, and the device itself does not allow the newly heated water to cool down, keeping the temperature at the required level. After the intake of hot water, the algorithm is repeated again. (See also: Sitemap 2)

The electric heater for the water heater is one of the most important parts, which must be cared for tirelessly in order to ensure accurate and long-term operation of the water heater. The indicator on the device makes it easy to find out what process is happening at the moment, since the heating is indicated by a light on, and the non-working state is off.

Of course, modern water heaters are equipped with all sorts of additional elements that facilitate the operation of the device and make it more functional, however, the basic principle of operation does not change from the heap of functions, whether they are water heaters with dry heat or not.

Reasons for replacing the heating element

To ensure long-term and trouble-free operation, it is recommended to clean the device and maintain it at least once a year. This procedure will allow you to identify existing problems in a timely manner and eliminate them, as well as keep the interior of the water heater clean, preventing corrosion from destroying vital parts. It is important to remember that no matter how good the performance of the anode is, anyway, this element will not last more than 17 months in uninterrupted operation. After this time, it must be changed. (See also: How to descale a boiler)



The replacement of the heater in the water heater is carried out depending on its condition, which is why the inspection should be regular, otherwise the breakdown will be a surprise. What does the technical inspection include:

• Disassembly of the device;
• Anode check;
• Checking the heating element;
• Cleaning of scale and deposits;
• Expert opinion.

It is thanks to a full examination by a specialist that it is possible to avoid untimely breakdowns, keep the device clean, monitor its condition, thereby extending and prolonging the life of the device. In addition, the cleaning of deposits has a positive effect on the health of the consumer, since the water, heated in a tank full of sludge, absorbs harmful trace elements.

The anode must be replaced when it is worn by at least 40% relative to its healthy state. It is easy to determine this shabby, you just need to look at it - a terrible look indicates the need for replacement. The magnesium anode is aimed at protecting the tank, taking the entire impact of corrosion on itself, thereby saving the metal of the tank. (See also: How to clean a boiler)

In addition, cleaning is extremely easy, since magnesium, coupled with oxygen, converts deposits into salt, which can be removed with a slight movement of the hand. That is why timely cleaning and replacement of the water heater is also necessary, as is the replacement of the heating element, regardless of the brand of the device, whether it is a Gorenje water heater with a dry heater or some other.



Many do not know how to find out about a heating element malfunction and the need to replace it as soon as possible, however, it is extremely simple to check the condition of the heater in the water heater:

1. If, when turned on, the RCD is constantly triggered. This moment indicates either a current leakage or a short circuit. Of course, the first thing to think about is the heating element.
2. The water does not heat up when the device is turned on. Of course, the refusal to produce heating is directly related to the failure of the heating element. In this case, you will need a multimeter, with which it is easy to identify the malfunction. The presence of voltage on the contacts during the test indicates a breakthrough.
3. Mechanical damage that is visible during inspection may also suggest an imminent replacement or a heating device that is currently needed.

Draining

The first thing to do before you start disassembling the water heater to replace the heating element is to drain the water, which can be done in four ways:

Simple equipment works in direct conjunction with a heating boiler, which is the source of energy for heating water in a storage water heater.

The efficiency of heating and providing hot water to all consumers of the house in full will directly depend on whether the piping of the boiler with an indirect heating boiler is correctly selected and implemented. .

Indirect heating boiler device

Connection Features

An indirect heating boiler is a storage tank, inside which one or more tubular heat exchangers are located. The hot coolant from the boiler unit circulates through the coil and heats the water in sufficient volume for domestic and household needs.

The principle of operation of the water heater is simple, difficulties arise during the installation and piping of thermal equipment.

Therefore, it will not be superfluous even before starting work to find out the features of connecting a water-heating device:

• The closer the boiler is to the boiler , the more efficient the heat exchange from the heating system.
• Water heater installation must be made in accordance with the manufacturer's recommendations - wall models are attached to the wall, floor models are installed on the floor.
• Cold water flow should be supplied through the lower pipe, and the hot intake - through the upper one, then the recirculation point will be in the center of the tank itself.
• Branch pipes for the inlet and outlet of the coolant should "look" towards the heating device. The movement of hot water or antifreeze through the coil must be from top to bottom.

Compliance with these simple rules guarantees the efficient operation of the boiler-boiler system, the efficiency of the heater will reach its maximum and there will be enough hot water for all consumers.

Strapping scheme options

Tying an indirect heating water heater involves connecting the pipelines of the heating boiler and the water supply system.

Connecting a storage water heater in an apartment - there will always be hot water

The efficiency of the entire system, both hot water and heating, depends on the correct installation and piping of the boiler.

Three common schemes are used:

• With the use of a servo and a three-way valve.
• With the use of two circulation pumps.
• With a hydraulic gun.

Scheme 1: piping an indirect heating boiler using a servomotor and a three-way control valve

This connection option is the simplest, it is used with a large consumption of hot water. Two circuits are connected to the heating boiler: the main one (for supplying heat to radiators or a water-heated floor system) and an auxiliary one (for heating water in the boiler). In order to correctly distribute the flow of coolant from the boiler unit, a three-way separating valve is connected between these circuits.

The thermostat controls the temperature of the water in the water heater tank, and, when the set value is reached, it sends a signal to the valve servo drive, which redirects the coolant flow to the heating circuit. When the water temperature in the boiler drops, the reverse switching occurs - the coolant enters the coil.

In this scheme, it is important to correctly adjust the operation of the thermostat - the temperature set in the water heater must be lower than that set on the thermostat of the heating boiler.

Otherwise, the heat carrier will not be able to heat the water in the tank of the water heater to the required temperature, respectively, the valve will not switch the heat flow to the heating circuit.

Boiler piping with servomotor and three-way valve

Scheme 2: piping a water heater with two pumps

Instead of a distribution valve, two pumps can be installed in parallel - for the heating circuit and the DHW. The pumps are controlled by the same thermostat installed in the boiler, which switches the operating mode of the pumping equipment to the specified parameters.

Here, too, the boiler circuit is given priority over the heating circuit, so the DHW pump is installed first. In this case, the efficiency of space heating will not decrease - the water in the boiler heats up quickly, so there is no critical decrease in temperature in the heating circuit.

In such a scheme, a check valve must be installed at the outlet of each pump - it will eliminate the mixing of oncoming coolant flows.

Piping a water heater with two pumps

Scheme 3: piping a boiler with a hydraulic arrow

The use of a hydraulic arrow is relevant for a heating system with a large number of independent branches - for a boiler, underfloor heating, several radiator circuits, etc.

Each individual circuit has its own recirculation pump, so without a hydraulic distributor, some problems may arise in the system:

Boiler piping for indirect heating with hydraulic switch

• Operation in abnormal mode will lead to failure of pumping equipment.
• System imbalance.
• Even when the pumps are stopped, heating of the radiators from the flows of other working devices is possible.
• The possibility of thermal shocks and, as a result, the destruction of cast-iron elements of heating equipment.

The hydraulic arrow stabilizes the pressure and flow of the coolant in all directions, evenly distributes heat between consumers and prevents the occurrence of thermal shocks. But the piping scheme for an indirect heating boiler with a hydraulic water separator causes certain difficulties in the design, installation and adjustment of operating devices, therefore, specialists should implement this connection option.

Boiler piping for indirect heating with recirculation

If hot water is not consumed for a long period of time, it starts to cool down. When you turn on the tap, you have to wait a few minutes until the hot flow from the boiler reaches the consumer. To reduce the time for draining the cooled water, they use a water heater piping with recirculation - the heated flow is forced to move through a closed cycle of pipelines and almost instantly “delivers” hot water to any point of consumption.

To implement such a scheme, another circuit with its own circulation pump is additionally mounted to the boiler, and additional piping elements are installed:

• Non-return valve (prevents back flow of water in the pipeline).
• Expansion tank (compensates pressure in the DHW circuit when the taps are closed).
• Automatic air vent (excludes airing of the pump).
• Safety valve (protects the water heater from overpressure).

Boiler piping for indirect heating with recirculation

The choice of a piping scheme for DHW and heating circuits, with or without the possibility of recirculation, depends on the characteristics of the heating system, accurate calculations of the power of the equipment and the need for hot water.

If you have any difficulties with the design and execution of work, it is better to seek help from specialized companies.
