When choosing a gas boiler for a home, you need to take into account a number of nuances related to the technical characteristics of the building, the installed heating system, the actual need for heat and hot water supply.

Domestic and foreign manufacturers offer a wide range of products. So finding a suitable specimen is not a problem. You just need to know what to focus on in order to understand how to choose a gas boiler for heating and not be mistaken. And it is also advisable to figure out how the options presented differ from each other, and which boiler to choose for a private house.

There are very few external differences in boilers of various modifications.

Features of gas heating

Despite the presence of a large number of alternatives (electricity, diesel, diesel fuel, fuel oil, firewood, coal), it is gas heating that still leads the world. And there are good reasons for this:

Profitability. Compared to other options, gas is relatively cheap and highly efficient. In this case, not only the cost of the fuel itself is taken into account, but also additional expenses for its storage (for the consumer), maintenance of the entire system, etc. So, parts for rare types of boilers can be difficult to get, sometimes you have to overpay. This is also taken into account.

Minimum human involvement. Heating a room with wood or coal requires a mechanical addition of fuel. Here everything is automated, including gas supply and flame control.

Cleanliness, absence of soot, soot and other things. Boilers can be easily installed in the kitchen.

The possibility of heating large rooms. One powerful boiler can handle a building on several floors.

At the same time, gas heating has its drawbacks. Or rather, specificity.

Installation should only be carried out by specialists. Source nehomesdeaf.org

In particular, the installation of the boiler requires approval from Gaztekhnadzor. Installation can only be entrusted to an organization with a license that gives the right to provide such services.

Do not forget that the gas is explosive. Therefore, it is extremely undesirable to save on automation: it monitors, among other things, its leakage (we are talking about modern technology).

In addition, you need to take care of ventilation. Combustion products can be naturally discharged from the building. But if problems arise with the draft, you need to change the installation location of the boiler (which is not always possible) or provide it forcibly.

Gas boilers for heating a private house: what they are

There are many different boilers on the market now. And you need to figure out how one type differs from another for the consumer. So it is easier to understand what to choose - a floor-standing gas boiler for heating a private house, or a hinged one, and with what functions, so as not to be mistaken. After all, otherwise you will have to either endure the inconvenience, or else spend extra money.

Single and double-circuit boilers

One of the main classification methods is the division into single and double-circuit boilers. The latter heat water not only for the heating system, but also for domestic needs. That is, there is no need to install an additional boiler.

The difference between single and double-circuit boilers Source remstrdom.ru

In a word, double-circuit gas boilers for heating a house are designed so that cold water from the central water supply system gets to them. Then the liquid heats up. In addition, there is a special valve in the design. It regulates where the hot water will be supplied. If you do not wash anything, do not take a bath, the boiler works to provide the heating system. But as soon as the tap opens, the valve closes the device. And water begins to flow to people.

Consider one more important point: to be able to take a bath, and not a contrast shower, you need a boiler with a capacity of at least 28 kW. The exact figures already depend on the size of the heated rooms and on the number of consumers. Roughly speaking, the more people need to wash, for example, the higher the load. And the more powerful the heater should be.

Clearly about the difference between single and double-circuit boilers in the video:

Can single-circuit boilers be used to heat domestic water? Yes, many modern models allow it. But you have to buy a boiler. It must be connected to the boiler, and in any case, the whole process, starting with the selection of a suitable model, should be entrusted to a specialist. Most consumers, however, in such situations usually just take a separate boiler, powered by electricity.

An example of a combination of a heating boiler and an indirect heating boiler Source nehomesdeaf.org

Which is the best option? Mostly they prefer double-circuit boilers: they are more convenient. But keep in mind that such models are always more expensive. The choice, in any case, depends on the consumers.

Floor-standing and wall-mounted boilers

The boilers may also differ in location in space: there are heating boilers for a private house, gas floor and wall. The latter take up less space and are generally more compact. In addition, they can be installed almost anywhere, subject to certain requirements. Also, for wall-mounted boilers, it is not necessary to organize a separate chimney: usually everything is solved at the expense of a pipe through which combustion products are removed.

What is the difference between floor-standing gas boilers for heating a house (they are officially called so)? They tend to be more powerful and noticeably heavier. For such models, more space is required: firstly, for the outline, and secondly, for the chimney. And this is not to mention a set consisting of a single-circuit boiler and a boiler. In addition, such specimens are quite noisy, so they are usually installed in a separate room (boiler room).

Most often, the boiler room is equipped in the basement or basement.

The choice of the optimal solution depends on what exactly you need in a particular case. That is, for an apartment or a small summer cottage, the best gas boiler for heating is a wall-mounted one. For a large house - floor-standing.

But when buying, you need to take into account another factor that can become critical: dependence on electricity. Floor-standing boilers work stably in this regard. Even if there is no electricity in the house, the heat will still remain. True, now more and more models with automation are being produced, which removes this advantage. Nevertheless, options can be found.

But all floor-standing models depend on voltage: power surges can disable equipment. Of course, no one bothers to put the stabilizer. But, firstly, this is an increase in costs. Secondly, the issue of power outages remains.

In general, both floor and wall products have their own advantages and disadvantages. Therefore, it is worth figuring out how to choose a gas boiler for a private house, depending on the specific room, on the quality of the electrical network and on financial capabilities.

Boilers with open or closed combustion chamber

Boilers can be with an open or closed combustion chamber. The former take air from the environment. Therefore, the issue of ventilation in this case becomes critical.

Ventilation is needed even more powerful than for a gas stove Source teplo-ltd.ru

There is a risk that oxygen will eventually run out. These models are considered obsolete in the EU, where they are widely abandoned due to increased safety requirements.

At the same time, boilers with an open combustion chamber are distinguished by a simple design. Therefore, they are less likely to fail (if we compare models in a low price category), are cheaper, and installation is easier. And it won't be difficult to find specialists who will deal with them.

Variants with a closed combustion chamber are considered more modern. They are safer, but require the installation of a chimney. However, this is just the case when you can spend money on the purchase of an expensive model and on installation once, and then not worry that there will not be enough oxygen in the room. Or that someone will suffer from poisoning with combustion products, as is the case with problems with boilers of the first type.

But the closed-camera models have their drawbacks. For example, you have to install a ventilation system that needs electricity. What, firstly, makes such a structure dependent (along with the light, heat will also disappear), and secondly, it increases the cost of providing a house.

Such a boiler needs supply and exhaust ventilation Source aquagroup.ru

The easiest way to stop is on boilers with a closed combustion chamber with a pipe leading to the outside. But for the installation of this model, there are far from always technical possibilities. So it is difficult to say in this situation which boiler to choose for the house. You need information about the object, whether it is possible to organize a separate room or bring the pipe outside.

How to choose a boiler for heating a private house

When choosing a gas boiler, you need to consider not only what they are. There are many more important parameters. Let's figure out what is worth paying attention to.

How to choose a gas boiler for a private house by power

It should be noted that it is very important to calculate the appropriate power, that is, no less and no more. With the first, everything is clear: the building simply will not warm up enough. But why is it undesirable for the boiler to be more powerful? In this case, the heating system starts to work unevenly, which leads to excessive wear. The result is frequent repairs and premature boiler replacement. In addition, the gas consumption increases.

Video description

Clearly about the choice of power in the video:

So how do you make the calculation? In general, it is best to contact experienced professionals with this. The fact is that when calculating, you need to take into account a huge number of different factors:

number of floors;

ceiling height;

the presence or absence of thermal insulation, as well as its type;

year of construction of the house;

wall material;

the selected method of heating water;

climatic zone.

And that's not all! It also matters whether the boiler is selected for townhouses or for ordinary houses (the former are usually warmer, although there are enough nuances here). The calculation is also influenced by the presence of other sources of heating in the building, for example, underfloor heating. In addition, an experienced specialist always specifies what the average room temperature should be. After all, there is a big difference between + 15 and + 23 degrees Celsius.

You can make an approximate calculation like this: you need to multiply the area of ​​the house by the indicator of the climatic zone, and divide the resulting amount by 10. This option is suitable for typical buildings with a ceiling height of up to 3 meters.

Let's say a building is located in the northern regions of Russia. There, the climatic coefficient is 2 kW. Therefore, the boiler must be 20 kW. But for a double-circuit, this figure must be multiplied by ¼. That is, the result is 25 kW. And remember that he is exemplary!

For an initial estimate of the power, you can use the table Source tarifi.info

Which boiler is better for a private house: the question of the chimney

Boilers with an open combustion chamber usually do not have a chimney. But in this case, it is necessary to ensure the removal of combustion products. And take into account that some part can still get into the air of the room. Therefore, for the safety of people, it is best to install such boilers in a separate room.

If we are talking about a closed chamber, then a forced draft is created there. And since the size and cross-section of the chimney does not affect the passage of the air flow (blowing depends on the fan), the installation is carried out using a coaxial pipe. It is easy to install and has a small diameter.

Turbine boilers are another popular option. Here, the air supply is provided by a special fan. Combustion products are discharged directly into the street. Moreover, the hole, as a rule, is small (it is visible from the outside).

When choosing this model, you can refuse to organize a chimney. But turbine structures need to be cleaned from time to time: if the entrance is clogged from the street, for example, with leaves, then the boiler will stop working.

Ventilation of a turbine boiler Source spetsotoplenie.ru

Each solution has its own advantages and disadvantages. But remember: only models with natural draft are considered non-volatile! So if electricity is often cut off in your village or area, then the only option would be products with natural draft and without a chimney.

Which boiler is better to choose for heating a house: manufacturers

There are a lot of options on the market. And there are more and more of them every year. What to do? Try to understand the range.

So, the most reliable ones are usually offered by Germany. These are Vaillant, Bosch, Buderus, Volf. Italian manufacturers produce copies with an optimal ratio of price, service life and reliability. Among the most famous is Ferrolli. Of the less promoted - Baxi, however, the brand is not very well known in Russia, but in Europe it has long and deservedly enjoyed a good reputation.

South Korean Kiturami will be an ideal option for heating large spaces. If the budget allows, you can pay attention to the Japanese company Rinnai. Its boilers are environmentally friendly, safe and extremely reliable: the warranty is given for 10 years. In addition, the automation itself regulates the operation of the device depending on the gas pressure.

Additional information for thinking about choosing a gas boiler in the video:

Of the domestic producers, Borinskoye LLC should be noted. The company's boilers are universal, suitable for most heating systems. Manufactured from high-strength steel types. Zhukovsky boilers are also well known to many. Produced in the Moscow region, they attract surprisingly affordable price and simple design.

It is difficult to say which option is better here. Much depends on what exactly you are counting on.

Which gas boiler is better to choose for heating a private house: price

Prices for boilers, in terms of the US dollar, start around $ 250 and go up to several thousand. Moreover, this amount does not always include delivery, and installation in most cases is paid separately.

In general, a double-circuit boiler is more expensive. But if we compare it not with a single-circuit, but with a set of a boiler and a boiler, then the calculations are no longer so unambiguous. More money will have to be spent on the chimney option. And the most affordable one is a floor-standing single-circuit boiler with natural draft of domestic production.

Single-circuit floor boiler Source etechzone.ru

True, paying less for the product does not mean that the issue of savings has been finally resolved, because if in a few years you have to undergo serious repairs or a complete replacement, then the benefit is frankly dubious. Therefore, it is undesirable to focus solely on the issue of price when buying a boiler.

The gas boiler is the heart of the heating system. It largely determines whether your house (or apartment) will warm up normally, how much you will have to pay for utilities every month, whether there will be a problem with dampness, etc. Therefore, when buying a gas boiler, there is no need to rush. Moreover, there are many types of gas heating boilers on the market for a private house - for every taste and wallet. This means that you have the opportunity to choose the truly optimal option. We have considered the main criteria for choosing a boiler for heating a private house, and we hope that you will not have any problems when choosing this important equipment.

Today's heating equipment market will satisfy the needs of any buyer, and offers for - are no exception. Here you can find many models of both budgetary units and expensive equipment of top-end configuration. In conditions of such saturation, it is difficult to determine which gas boiler is the most reliable, especially if you did not have to buy these devices before.

The statistics of the sale of these units by dealers and the analysis of the popularity of various models of gas heating boilers with the consumer allow us to form and publish such a dynamic factor as the rating of this equipment, which will help the inexperienced buyer.

Qualitative wall-mounted double-circuit gas boilers are found in several manufacturers.

Based on brand reputation and technical characteristics, you can make rating the most profitable models.

Wall mounted gas boilers are easy to install and have optimal power.

What is the peculiarity of double-circuit wall-mounted gas boilers

Two tasks, which perform double-circuit wall-mounted gas boilers: providing premises with heating and supplying them with hot water.

During the operation of the unit, the gas burns out and heats up the heat exchanger, which transfers energy to the coolant, which spreads through the radiators and taps.

Wall-mounted models of double-circuit devices have a number of advantages:

• Optimum power.
• Minimum installation space.
• Affordable price.

Unlike floor-standing appliances, wall-mounted appliances can be installed on the territory of a heated room (for example, in the kitchen), and not in a separate one, like most floor-standing ones. But wall-mounted double-circuit boilers also have minuses... These include:

• Power limitations.
• Limit by type of installed elements.
• The need for preparation walls for installation.

​

The more powerful the boiler, the larger it is. And the wall option should not be too heavy.

it one of the reasons for which cast iron heat exchangers are avoided in wall models. They are made from a different material.

To hold firmly several tens of kilograms, it is required to securely attach the device to the wall.

Options

The place of gas units in the list is influenced by their parameters, or rather, a whole range of characteristics. Device power: the best option 24 kW, responsible for sufficient heating - about 82 ° C, as well as the presence of hot water in the tap - up to 60 ° C.

Gas consumption: an average of 2.8 cubic meters m of natural or 2 kg of liquefied gas per hour, demonstrates the cost of heat supply. In addition to the heating function, the reliability of the gas boiler is of great importance. Electrodependent and autonomous devices must be equipped with a security system.

Attention! In some cases, for electrically dependent units, due to the high sensitivity of the security system sensors, it is necessary to use Surge Protectors.

The elements of the safety system usually solve such problems as: gas control, automatic diagnostics, overheating protection, frost protection, as well as pump blocking.

These parameters affect the efficiency and reliability of the boiler, since they increase its productivity, reduce the risk of accidents, increase the service life.

​

It is important to take them into account, because they help to keep the equipment working, eliminate the threat to human health and save on fuel.

For example, by choosing boilers with adjustable power when purchasing, you can adjust the operating mode of the device depending on the weather on the street and the presence of a person in the room, and not to operate the boiler at full capacity around the clock, wasting excess gas in vain.

In addition, the well-thought-out design of the devices from the list guarantees high safety, which is very important for wall-mounted models, which are often installed inside the house.

Although the list suggests the most efficient models to operate, the selection of the appropriate device depends on specific characteristics: area, heat loss, operation options.

Nevertheless, you can try to choose the most versatile and reliable type of gas boiler.

0 out of 5.
Rated: 0 readers.

Since gas in Russia costs an order of magnitude lower than electricity, many owners of private houses turn to the installation of gas boilers. However, economic parameters are far from the only advantage of units of this type over others - they include high thermal power, optimal level of efficiency, minimum amount of harmful emissions, as well as the possibility of heating large premises (on average, from 150 to 300 square meters).

Of course, like any other technique, gas boilers have disadvantages. These include the strict coordination of the installation with the federal service of Gaztekhnadzor, equipping the house with a chimney to remove (a small amount) of combustion products, as well as the introduction of automation to detect gas leaks.

In our rating you will find 15 of the best and highest quality gas boilers, the purchase of which will provide you with warmth and hot water for many years. Before that, we advise you to study some of the nuances of choosing a gas boiler for a house or apartment.

The right choice - double-circuit or single-circuit?

As you know, according to the number of circuits, gas boilers are usually divided into single-circuit and double-circuit. Which one is better? The correct choice depends on the main purpose of the device.

Single-circuit ones are designed exclusively for the operation of the main coolant (radiators, pipes, etc.), that is, they are bought to provide heating. Most often, such devices are installed in summer cottages and in places where there is no water supply. In this case, a boiler is purchased for a single-circuit boiler to heat water in an autonomous water supply system.

Double-circuit boilers are 2 in 1 devices. They can both heat the house and provide hot water supply. The coolant and the boiler in such a device are collected in one unit. If hot water is not consumed, the heating medium circulates in the heating circuit. As soon as the user opens the hot water tap, the system switches the valves so that the heat carrier is directed to the second circuit. This is the most popular type of gas boilers, which are installed in most apartments and private houses.

Heated power

The more powerful the boiler is, the higher its cost. In order not to overpay extra money and eliminate additional costs in the future (the more powerful the boiler, the more it consumes resources), it is important to calculate what kind of gas boiler you need. An approximate calculation is as follows: for 10 sq. m. of a well-insulated room (ceiling height up to 3 m) should account for 1 kW of the boiler's thermal power. For a poorly insulated room, another 30-50% is added to the heat output.

For a country house of 50 sq. m. it is enough to purchase a gas boiler with a capacity of 7 - 12 kW. But for a house with an area of ​​200 sq. m. you will need a more powerful device: 23 - 25 kW. Most modern double-circuit gas boilers are produced with a thermal power of 24 kW.

There is one more important detail when choosing the boiler power. If you take a device that is too powerful for a small room (for example, a 24 kW boiler for a one-room apartment of 40 sq. M.), Then the boiler will quickly heat up the coolant and turn off. As soon as the water cools down, the boiler will start up again. Constant switching on and off will occur very often, which will lead to accelerated wear and increased gas consumption. In turn, a boiler with a lower power will provide a smooth combustion, and on-off will occur much less frequently.

Which company to give preference to?

The highest quality and most reliable gas boilers are manufactured by Italian, German and South Korean companies. Even taking into account the fact that many companies locate their production facilities in China, purchasing a gas boiler of a popular brand is better than buying a little-known device.

To facilitate your choice, we list the list of the best manufacturers of gas boilers:

• Navien (South Korea)
• Bosch (Germany)
• Ariston (Italy)
• Baxi (Italy)
• Buderus (Germany)
• Vaillant (Germany)
• Protherm (Slovakia)
• Viessmann (Germany)
• Kiturami (South Korea)

Voltage stabilizer for a gas boiler - is it necessary or not?

After purchasing a gas boiler, it is advisable to install a voltage stabilizer. Especially if your network suffers from frequent power surges. The fact is that in the event of a boiler failure due to a power surge, it will not work to exchange the device under warranty. The requirement for the quality of the network is spelled out in each warranty agreement. Therefore, it is better to spend an extra 3-5 thousand rubles for a device with a capacity of up to 1 kW (and a powerful stabilizer for the boiler is not needed) than to end up losing tens of thousands of rubles.

Best inexpensive wall mounted gas boilers

The main advantages of wall-mounted gas boilers are lower price and compactness in placement. They are more preferable for areas with limited space. For example, for an apartment. The disadvantages of wall-mounted models are lower power and shorter service life, in contrast to floor-standing devices.

1 Vaillant turboTEC pro VUW 242 / 5-3

High efficiency with maximum reliability
Country: Germany
Average price: 53,700 rubles.
Rating (2019): 4.5

The leading line of the rating is occupied by not the cheapest in the category, but the most reliable and efficient gas boiler Vaillant turboTEC pro VUW 242 / 5-3. The craftsmanship of German manufacturers knows no bounds: for more than ten years of production, this model has heard mainly laudatory reviews regarding various aspects of the design and operation.

A double-circuit boiler can be used not only as a heater: when a cold water source is connected to it, it copes no less brilliantly with the functions of a boiler. The maximum temperature of the DHW circuit is 65 degrees Celsius, which is more than optimal for home use. 24 kW of power is enough for heating residential areas up to 240 square meters. In this mode, Vaillant turboTEC pro VUW 242 / 5-3 shows the highest efficiency value - about 91%. It is also worth noting the presence of six levels of protection, electronic control with the ability to modulate the flame, as well as a six-liter (generally standard) expansion tank.

The main disadvantages of the model affect the purely marketing side of the manufacturing company. The cost of servicing Vaillant boilers is very high, and the owner will bear the costs both for the purchase of a branded part and for its subsequent installation (approximately 50 to 50). Fortunately, serious breakdowns of units are extremely rare.

The best floor-standing gas boilers from the budget category

Floor standing gas boilers are considered more reliable and durable. They cost more than wall-mounted models, but they gain in power and can heat rooms from 200 sq. m. For the installation of floor-standing boilers, it is recommended to use a separate room (boiler room).

3 Protherm Wolf 16 KSO

The best automation. Developed service network
Country: Slovakia
Average price: 21,200 rubles.
Rating (2019): 4.5

The non-volatile "floor stand" presented by the Slovak company "Proterm" is surprisingly small in size. At only 39 cm wide, almost 75 cm high and 46 cm deep, it can be easily installed in any small room. In the "Wolf" series, 2 modifications are presented, differing only in thermal power of 12.5 and 16 kW, sufficient for heating a private house with an area of ​​30 to 150 sq. m.

The fact that the main production site of Protherm is located at the Vaillant plant, the world-famous German manufacturer of gas boilers, will tell a lot about the quality of workmanship. Floor-standing units are made of steel 3 mm thick, equipped with temperature and emergency controllers, a draft stabilizer, and a SIT gas burner device (Italy). The design is easy to install and operate, and therefore does not cause complaints from users. However, it must be taken into account that the 2-year warranty for the unit applies if installed by a certified specialist.

2 ATON Atmo 30E

The most powerful gas boiler (30 kW)
Country Ukraine
Average price: 27 800 rubles.
Rating (2019): 4.0

A powerful single-circuit boiler of Ukrainian origin, which has everything you need to ensure stable heating of premises up to 300 square meters. Actually, ATON Atmo 30E fulfills its main task beyond praise - the absence of a second circuit for heating water allowed Ukrainian craftsmen to pay more attention and funds to improve and fine-tune the heating function.

For normal operation, the boiler requires 3.3 cubic meters of gas per hour. This is quite a lot (especially for a budget model), however, almost all the energy from the combustion of fossil fuel (the unit efficiency is 90%) is converted into thermal energy, which, in combination with 30 kW of power, results in such a vast heated area.

In general, the presence of the principle of economy is felt in the model: the designer cut off almost all "civilized" functions, leaving only the most necessary for the boiler - a thermometer, gas control and a thermostat to protect against overheating. This step has led to a noticeable increase in the level of reliability, since fewer components lead to fewer possible (elementary) failures. In general, ATON Atmo 30E is an ideal boiler for a large country house, not burdened with additional functions and the need to work as a boiler.

Lemax Premium-25B is an inexpensive floor-standing convection-type gas boiler. Produced in Taganrog. Able to efficiently heat a house up to 250 sq. m. with an efficiency of 90%. The low cost of the device is due to the steel structure of the heat exchanger. Such material is more susceptible to corrosion than copper and cast iron heat exchangers. However, the developer has provided a special heat-insulating coating with inhibitors, which should significantly reduce the corrosion of the heat exchanger.

The boiler is equipped with everything necessary for the safe operation of the system: heat exchanger overheating sensor, thermometer, gas control. There is auto ignition - ignition is carried out automatically. This indicates a higher reliability and efficiency in comparison with piezo-ignited devices. The nominal pressure of natural gas is 13 mbar, that is, the boiler will operate at full capacity even at low pressure indicators in the gas network (which is not uncommon in Russia). This is the best indicator in our review of budget floor standing boilers.

It is worth noting that the Lemax boiler is designed for an open heating system, therefore, when buying it, a chimney must be provided in the house for the removal of combustion products.

Most of the user reviews speak of Lemax's "indestructibility" and almost silent operation. It is an economical and hassle-free boiler at an affordable price, with a 3-year manufacturer's warranty. One of the best deals in the budget segment.

The best floor-standing gas boilers: price - quality

Here are the most optimal in terms of price and quality floor standing gas boilers. The most popular units among buyers.

3 Buderus Logano G124 WS-32

Increased efficiency. Large assortment of additional equipment
Country: Germany
Average price: 102,000 rubles.
Rating (2019): 4.5

The "Logano" line includes 4 standard sizes (from 20 to 32 kW) of low-temperature boilers, which are considered more profitable and safer in comparison with high-temperature boilers. In addition, low temperatures in the heating system create the most comfortable conditions for a person, while excluding strong temperature drops in an apartment or a private cottage. The unit can be built into the heating system using underfloor heating, and if the heat loss at home is too high, it is possible to supplement it with radiators.

Additional heat savings are facilitated by the special design of the cast-iron heat exchanger and thermal insulation 80 mm thick. In order for buyers to individually assemble the heating device, the company offers an extensive selection of additional parts and assemblies, which, I must say, are very expensive. For example, the AW 50.2-Kombi flue gas control system is offered to be bought for almost 9.5 thousand rubles, and at least 50 thousand rubles will have to be paid for the Logalux SU floor-standing water heater. Nevertheless, consumers are satisfied with the economy, ease of operation and durability of the model and recommend it for purchase.

2 Navien GA 23KN

Stability and safety of operation. 3 year warranty
Country: South Korea
Average price: 34,000 rubles.

Last June, Navien Rus LLC was awarded the Company of the Year award in the Best Supplier of Engineering Equipment category. A month later, the company celebrated with a 3-day conference the sale in Russia of the millionth hinged boiler. In addition, over the past 4 years, the brand has gained 46.6% of the votes and has repeatedly confirmed the title of "Brand No. 1" in the category "Boilers for heating". What is remarkable about his products, that they vote for it not only by word, but also by wallet?

First of all, buyers are attracted by the quite reasonable price for the unit, the appearance of which alone speaks of the unsurpassed quality inherent in South Korean technology. They are not disappointed even after getting acquainted with the technical characteristics, in particular, the presence of a 2nd circuit, a closed combustion chamber and an electronic control system with a remote control included. Despite the "overseas" origin, the model is fully adapted to Russian operating conditions and is designed to operate with a minimum gas pressure and water supply - 4 mbar and 0.1 bar, respectively.

1 Baxi SLIM 2.300 Fi

Best functionality and quality
Country: Italy
Average price: 131 838 rub.
Rating (2019): 5.0

If you are looking for a high quality and modern gas boiler from a trusted manufacturer, then the Baxi SLIM 2.300 Fi is one of the best options. This is the most expensive device in our review, with a price tag of about $ 2,000, which is quite acceptable for those who do not like to skimp on quality.

Double-circuit "Baxi" is able to heat a cottage up to 300 sq. m. with an efficiency factor of 90%. It can work in a closed heating system due to the built-in circulation pump. The built-in expansion tank will maintain the optimal pressure in the heating system, accepting the excess during heating and replenishing the losses during cooling of the heat carrier. Baxi SLIM 2.300 Fi is one of the best boilers for underfloor heating.

The material of the primary heat exchanger is the best here - cast iron. As you know, cast iron is resistant to corrosion, durable and reliable. Additional functions include an air vent, safety valve and pump blockage protection.

Baxi SLIM 2.300 Fi is one of the best-selling floor-standing gas boilers in the middle and high price segment.

The best wall-mounted gas boilers of the condensing principle of operation

During the operation of the gas boiler, condensate forms, which can be used to generate heat energy. This is exactly what happens in boilers of the condensing principle of operation, where additional energy from condensate is generated using a special heat exchanger (economizer). This will undoubtedly increase the efficiency of the device.

Installing a condensing boiler allows you to save up to 20% on gas bills. Thus, the efficiency of a conventional convection boiler is on average 92%, while a condensing boiler is capable of operating with an efficiency of 109%. True, the purchase of a condensing model will be much more expensive than a convection model and, perhaps, such a decision will be justified when heating sufficient areas.

3 Baxi POWER HT 1.450

Optimal performance and safety
Country: Italy
Average price: 147,000 rubles.
Rating (2019): 4.7

Distinctive characteristics of the model are high power indicators of 45 kW, efficiency of 107.5% and the ability to maintain 100% power when the inlet pressure drops to 5 mbar. The device implements all modern protection methods, including protection against freezing, overheating, as well as gas control and a self-diagnosis system. The built-in microprocessor constantly monitors the status of the sensors and in the event of abnormal situations (for example, a drop in water pressure, overheating or cut off the gas supply) automatically turns off the boiler. It is also worth noting the presence of an auto-ignition, an air vent and the ability to connect a warm floor.

Baxi POWER HT 1.450 is one of the most reliable premium floor standing boilers. The obvious disadvantages of the device include only the high price.

2 Baxi Duo-tec Compact 1.24

Profitable price. Minimum consumption of liquefied gas
Country: Italy
Average price: 52,500 rubles.
Rating (2019): 4.7

Baxi Duo-tec Compact 1.24 is one of the most affordable condensing gas boilers. Despite the low price, the power of the device is 24 kW with an efficiency of 105.7%. This is an excellent model for installation in a country cottage or summer cottage, since the boiler can operate on liquefied gas with a minimum consumption of 1.92 kg / h. If desired, Baxi Duo-tec Compact 1.24 can be connected to the underfloor heating system. The built-in expansion tank will compensate for the expansion of the coolant. The Duo-tec Compact series is characterized by easy installation, simple operation and the ability to adapt to the gas quality. They work with a power modulation ratio of 1: 7.

It is a pity that the boiler is single-circuit and can only be used for the heating system.

1 Protherm Lynx condensing

Combination of high power and compactness. Auto control
Country: Slovakia
Average price: 57,000 rubles.
Rating (2019): 4.8

In Europe, traditional boilers are practically not used - they were replaced by condensing units like Protherm "Lynx". Models of this line have been produced since 2002 and are still in demand on the market. There are a lot of reasons for the popularity: here is also the affordability - mounted condensing boilers with similar characteristics from competitors are 1.5 times more expensive, and rich equipment, and still relevant design.

The system of forced removal of combustion products allows the device to be mounted indoors without a chimney. Fuel consumption is 3.2 cubic meters. m / hour and gives savings of the order of 20 - 30% in comparison with convection devices. Thanks to two preset modes and an automatic control system with an electronic display, setting the desired temperature in a private house is easy. Additionally, the developers have provided the ability to connect an external controller. Users do not complain about any breakdowns, which allows us to judge the high reliability of the Lynx.

The best double-circuit boilers

When choosing a double-circuit boiler, as well as a single-circuit boiler, you need to pay special attention to power. If the residents of the house plan to take a bath often, the minimum power of the equipment should be at least 18 kW, if the shower is a priority, then it is allowed to install a less powerful unit - from 10 kW. Even before buying, it is advisable to check whether the manufacturer has skimped on the circulation pump, safety valve, diaphragm expansion tank and fittings in the kit.

3 Bosch Gaz 6000 W WBN 6000-18 С

Patented heat exchanger design. Low noise level
Country: Germany (produced in Russia)
Average price: 29 100 rubles.
Rating (2019): 4.5

Dispensing hot water usually takes a long time. If you do not want to put up with such inconvenience, take a closer look at the Bosch Gaz 6000 W WBN 6000-18 C boiler. Its plate heat exchanger is designed in such a way that the water is heated in a matter of seconds. The presence of two separate heat exchangers makes the boiler more efficient (30 ° - 8.6 l / min, 50 ° - 5.1 l / min) and not demanding on water quality.

Among other advantages of heating equipment, one should note the minimum noise level - the sound of a working boiler is compared by many users to the noise of a computer or refrigerator. Efficiency is another Bosch feature. It is proposed to provide it by switching on the "Eco" mode, which provides for heating water only when it is taken away. If the most flexible automatic regulation is required, it is possible to connect external regulators to the built-in automatics, allowing the system to be controlled remotely.

2 Ariston CARES X 15 FF NG

Fine temperature setting. Sophisticated security system
Country: Italy
Average price: 35,500 rubles.
Rating (2019): 4.7

The Ariston CARES series are the most compact traditional and wall-mounted gas boilers. The 15-kilowatt tube is intended for installation in heating systems of small private houses, summer cottages and apartments, in the limited space of which its dimensions - 400x700x319 mm - take root very successfully. And it is very handy that the unit setting allows you to set the temperature of the heating circuit with an accuracy of 1 °, thereby providing an ideal microclimate in a small room.

The design is assembled on a modular basis, due to which the number of threaded connections - points of potential leaks - has become minimal. Built-in safety systems such as gas control, anti-freeze mode, safety valve are responsible for the smooth operation and increase the safety of the device. And at the same time, the manufacturer provides all the necessary options for comfortable operation - a large electronic display, auto-ignition, status indication and the ability to connect external control. Of course, this unit deserves a place in our rating!

1 Rinnai RB-207RMF

The best digital technologies. 18 Japanese patents
Country: Japan
Average price: 52 800 rubles.
Rating (2019): 4.9

The Japanese are not in vain known as techno-freaks - they even managed to fill the Rinnai RB-207RMF gas boiler with the most modern electronics. What makes it unique is, first of all, the algorithm for automatically maintaining the optimal ratio of the gas-air mixture in the working chamber. The process is controlled by a “brain” with sensory sensors. This achieves an unprecedentedly wide range of output power - from 17 to 100% and, as a result, a decrease in gas consumption and an increase in the life of the primary heat exchanger.

The model can be controlled from the "Standard" modification panel (supplied in the basic kit), "Deluxe" or Wi-Fi. With its help, you can program an individual heating and hot water supply mode, which will be automatically maintained depending on the indicators of the sensors outside and inside the building. Changes in the settings are duplicated by the voice navigator. Two microprocessors are responsible for safety at once, controlling and correcting each other's work. This is not a boiler, but a space rocket, not otherwise!
