TOP 10 non-volatile gas boilers for heating a private house: an overview of models + selection rules

1 Baxi SLIM 2.300Fi

If you are looking for a high-quality and modern gas boiler from a trusted manufacturer, then 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 around $ 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 with an area of ​​​​up to 300 square meters. m. with an efficiency index 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 excess during heating and replenishing losses during coolant cooling. Baxi SLIM 2.300 Fi is one of the best boilers for underfloor heating.

The material of the primary heat exchanger here is the best - cast iron. As you know, cast iron is resistant to corrosion, durable and reliable. Of the additional functions, it is worth noting the air vent, safety valve and pump blocking protection.

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

Operating principle

Single-circuit installations operate on the principle of flow heating of the coolant using a gas burner. The process takes place in the heat exchanger, which receives the return flow from the heating circuit.

Receiving the maximum temperature, the liquid leaves the heat exchanger and enters the three-way valve. In it, a colder return is mixed with a hot stream in order to create the temperature set by the mode.

The prepared coolant exits the boiler with the help of a circulation pump and is sent to the heating circuit for the next circulation cycle. The circulation pump is responsible for moving the liquid, and the turbocharger fan is responsible for the air supply and smoke exhaust.

The control over the operation of the unit is carried out by a self-diagnostic system (sensors, thermistors) connected to the electronic control board.

All arising problems are displayed on the display in the form of a special designation of a particular error.

The main nuances of choosing a gas boiler

The absence or constant interruptions of centralized heating and hot water supply force the owners of cottages and city apartments to create their own autonomous systems.

Their main element is a boiler, which, by burning fuel, heats the coolant for the heating system and water for domestic needs.

The choice in favor of gas equipment is due to the cost-effectiveness of using gas as a fuel. All other options for combustible fuel are more expensive or give less heat at times.

Plus, modern heaters of this type do not require constant supervision. I connected the unit to the main pipe or cylinder, and it works smoothly as long as there is something to burn.

The use of natural gas is the optimal solution for heating a private house in terms of fuel costs and operating costs.

However, in order for the gas boiler to function properly and in optimal mode, it is necessary to choose it correctly when buying and regularly service it after connection.

There are many different in functionality and special modules within the models of this equipment. The purchase of a gas heating unit should be approached thoughtfully.

There are many criteria for choosing a gas boiler, but the main ones are:

1. The power output by the device.
2. Layout solution (number of circuits, body type and heat exchanger material).
3. Place for installation.
4. Availability of automation for safe operation.

All these questions are closely related. The lack of space for a large unit or the desire to mount a device with an aesthetic appearance in the kitchen forces you to choose a wall-mounted model of less power than the floor version.And the need to heat hot water for the washbasin and shower makes you look for a boiler with two circuits.

When choosing a heater, you should remember about the need to repair it, if there is no workshop for servicing the selected model nearby, then you should look for another option

The most popular manufacturers

The leaders in the manufacture of single-circuit boilers are European companies.

These include:

• Viessmann. A German company known for the high quality and durability of its products;
• Vaillant. Also a German company, well known to Russian users. Produces several series of boilers adapted to difficult Russian operating conditions;
• Baxi. One of the leaders of Italian heat engineering;
• Ariston. Another representative of the Italian industry. It is famous for its quality and affordable prices;
• Bosch. A transnational German concern that produces a huge number of technical devices, including single-circuit gas boilers;
• Protherm. Slovak company offering a wide range of quality gas boilers;
• Navien. This is a company from South Korea. It is famous for its high quality and affordable prices for all models of boilers.

The above list cannot be considered complete. These manufacturers are only the most well-known on the Russian market.

2 ATON Atmo 30E

A powerful single-circuit boiler of Ukrainian origin, which has everything necessary to ensure stable heating of rooms up to 300 square meters. Actually, ATON Atmo 30E performs its main task beyond praise - the absence of a second circuit for heating water allowed Ukrainian craftsmen to pay more attention and funds to improving and fine-tuning 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), but almost all the energy from the combustion of natural fuel (the efficiency of the unit is 90%) is converted into thermal energy, which, combined 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 the boiler with only the most necessary things - a thermometer, gas control and an overheat protection thermostat. This step led to a marked 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.

1 Vaillant turboTEC pro VUW 242/5-3

The leading line of the rating is 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 mostly laudatory reviews regarding various aspects of the design device and operation.

A double-circuit boiler can be used not only as a heater: when a source of cold water is connected to it, it no less brilliantly copes with the functions of a boiler. The maximum temperature of the DHW circuit is 65 degrees Celsius - for home use, this is more than optimal.24 kW of power is enough to heat 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 shortcomings of the model affect the purely marketing side of the manufacturer. The cost of servicing Vaillant boilers is very high, and the owner will incur costs both for the purchase of a branded part and for its subsequent installation (about 50 to 50). Fortunately, serious breakdowns of the units are extremely rare.

Design features of gas boilers

The choice of a wall-mounted gas boiler for a private house begins with determining the required design. There are three types of gas boiler designs, each of which has its own advantages:

• Classic. These are conventional models that heat the coolant (water) only by burning natural gas. They are easy to maintain and cheaper than other types. However, their efficiency is 10-15% lower than that of condensing ones. The vast majority of buyers buy the classic models.
• Condensing. These devices generate additional heat by condensing water vapor from the combustion product. Here, the design has an additional heat exchanger, where condensate enters, which is not removed through the chimney. Due to the additionally generated heat, the efficiency of the device increases and the gas consumption decreases (in comparison with classical devices).The savings become especially noticeable when the device is operating in low-temperature conditions, for example, for heating a warm floor at a temperature of 40 C. True, condensing devices are much more expensive than classic ones.
• With built-in boiler. The built-in boiler has mainly double-circuit boilers. Such models simultaneously heat the room and heat water for water supply. Thanks to the presence of a boiler, there is always hot water. Moreover, the efficiency of work does not depend on the pressure in the pipeline, as, for example, in flow devices, where, with a low pressure of water, the heater may simply not turn on. However, boiler boilers are heavier and larger, so they are more difficult to mount. They also cost several times more than classic or condensing ones.

If you just need to heat your house with a radiator heating system, take a classic model of the appropriate capacity. If you have a warm floor, you should think about purchasing a condensation model.

Criterias of choice

heated area (we are looking for models for rooms up to 100 m², up to 200 m², up to 300 m² and over 350 m²);
the number of circuits and the required volume of hot water supply (single-circuit with a built-in tank for a small apartment and 1-2 people, single-circuit with an indirect heating tank for a family of 3-4 people, double-circuit with one draw-off point, with two, etc.);
volatile, but economical, automated and ultra-modern or non-volatile, but very simple and unpretentious with mechanical control and a minimum of sensors (in areas with frequent and long power outages, the owners risk being left without heating in winter by choosing a volatile boiler);
if there is a separate boiler room, it can be taken with an open chamber, or it can be closed for a coaxial chimney, in a separate room it is easier to organize a bundle of a wall-mounted single-circuit boiler + a heating tank for hot water supply;
if there are problems with pressure in the gas main, a voltage drop in the mains, then look for boilers whose "brains" can withstand it, not all expensive imported models will be able to ensure trouble-free operation in our extreme conditions;
pay attention to additional functions not only for the boiler, for example, it is very convenient to have a chimney with frost protection, otherwise you will have to manually get rid of terrible icicles on the coaxial pipe or on the roof near the chimney, which will stop the boiler from working;
remember that the boiler will be only a part of the heating system, not only it is important, but also the optimally coordinated and correct operation of all components;
think over the maximum protection against gas leakage, do not save on safety, relying only on the brand or the reliability of modern electronics.

Non-volatile boilers are optimal in Russian conditions. In cold weather, it is too dangerous to remain without heating, so the independence of boilers is highly valued by users.

Additional features and capabilities

Additional features and capabilities can significantly affect the choice of a suitable model:

• Circulation pump. Such a device forcibly “drives” the coolant through the pipeline. Thanks to this, heat is evenly distributed over all radiators. Also, if the system becomes airy, it will be easier to expel the air. If the house is larger than 50 m2, take a device with a pump. True, turning the pump on and off creates some noise, so it is better to install the boiler away from the bedroom.
• WiFi. Some devices can be controlled not only from the standard panel, but also via Wi-Fi. Depending on the specific model, control can be carried out from an application or a page in a browser (you need to check with the manufacturer).At the same time, you can adjust the temperature regime, receive a report on failures and reconnection, pump operation, etc. One of these representatives of smart boilers is Ariston ALTEAS X with a capacity of 24 kW.

• Programmer. This is a part that allows you to program the thermostat for a specific on / off time. Some models allow you to program the operation of the device only during the day, and there are those for which you can set different operating modes on certain days of the week.
• Warm floor mode. This mode is specially designed for operation with underfloor heating and provides a lower coolant temperature than when working with the main heating system. As a rule, this model also has a more powerful circulation pump.

What should be guided

When asked how to choose a heating boiler, they often answer that the main criterion is the availability of a particular fuel. In this context, we distinguish several types of boilers.

gas boilers

Gas boilers are the most common types of heating equipment. This is due to the fact that fuel for such boilers is not very expensive, it is available to a wide range of consumers. What are gas heating boilers? They differ from each other depending on what type of burner - atmospheric or inflatable. In the first case, the exhaust gas goes through the chimney, and in the second, all combustion products leave through a special pipe with the help of a fan. Of course, the second version will be a little more expensive, but it will not require smoke removal.

Wall mounted gas boiler

As for the method of placing the boilers, the choice of a heating boiler assumes the presence of floor and wall models. Which heating boiler is better in this case - there is no answer. After all, everything will depend on what goals you are pursuing. If, in addition to heating, you need to conduct hot water, then you can install modern wall-mounted heating boilers. So you will not need to install a boiler for heating water, and this is a financial savings. Also, in the case of wall-mounted models, combustion products can be removed directly to the street. And the small size of such devices will allow them to fit perfectly into the interior.

The disadvantage of wall models is their dependence on electrical energy.

Electric boilers

Next, consider electric heating boilers. If there is no mains gas in your area, an electric boiler can save you. Such types of heating boilers are small in size, so they can be used in small houses, as well as in cottages from 100 sq.m. All combustion products will be harmless from an environmental point of view. And the installation of such a boiler does not require special skills. It is worth noting that electric boilers are not very common. After all, fuel is expensive, and prices for it are rising and rising. If you are asking which heating boilers are better in terms of economy, then this is not an option in this case. Very often, electric boilers serve as spare appliances for heating.

Solid fuel boilers

Now it's time to consider what solid fuel heating boilers are. Such boilers are considered the most ancient, such a system has been used for space heating for a long time.And the reason for this is simple - fuel for such devices is available, it can be firewood, coke, peat, coal, etc. The only drawback is that such boilers are not able to work offline.

Gas generating solid fuel boiler

Modification of such boilers are gas generating devices. Such a boiler differs in that it is possible to control the combustion process, and the performance is regulated within 30-100 percent. When you think about how to choose a heating boiler, you should know that the fuel used by such boilers is firewood, their humidity should not be less than 30%. Gas-fired boilers depend on the supply of electrical energy. But they also have advantages in comparison with solid propellant ones. They have a high efficiency, which is twice as high as solid fuel appliances. And from the point of view of environmental pollution, they are environmentally friendly, since the combustion products will not enter the chimney, but will serve to form gas.

The rating of heating boilers shows that single-circuit gas-generating boilers cannot be used to heat water. And if we consider automation, then it is great. You can often find programmers on such devices - they regulate the temperature of the heat carrier and give signals if there is an emergency danger.

Gas-fired boilers in a private house are an expensive pleasure. After all, the cost of a heating boiler is high.

Oil boilers

Now let's look at liquid fuel boilers. As a working resource, such devices use diesel fuel. For the operation of such boilers, additional components will be needed - fuel tanks and a room specifically for the boiler.If you are thinking about which boiler to choose for heating, then we note that liquid fuel boilers have a very expensive burner, which can sometimes cost as much as a gas boiler with an atmospheric burner. But such a device has different power levels, which is why it is profitable to use it from an economic point of view.

In addition to diesel fuel, liquid fuel boilers can also use gas. For this, replaceable burners or special burners are used, which are capable of operating on two types of fuel.

Oil boiler

The most popular manufacturers and their brief description

The leading manufacturers of floor single-circuit boilers are European companies, although domestic designs are optimal for Russian conditions.

The most famous companies are:

• Viessmann. German company, one of the most famous and reliable companies producing heat engineering products;
• Protherm. A Slovak company producing a wide range of heating boilers. All series bear the names of animals of different species;
• Buderus. "Daughter" of the world famous concern Bosh, which fully characterizes the quality and reliability of products;

• Lemax. Russian manufacturer of non-volatile floor gas boilers. When developing the project, all the features of working in difficult conditions were taken into account;
• Navien. Korean boilers, successfully combining high quality and affordable prices.

You can continue the list of manufacturers for a very long time. All current firms care about the quality and reliability of their products, trying to outperform competitors and cover the maximum number of users.

Conclusion

In conclusion, it should be noted the undoubted leadership of gas boilers in comparison with their other types. These devices allow you to get a stable temperature in the house, they consume fuel economically and do not need the constant attention of the owner. On sale there are a large number of models that can heat the house and provide it with hot water. The only task of the user is the correct choice and competent operation of the unit.
