We ask a lot of questions, considering gas boilers for heating a private house - how to choose the required power, what type to give preference to, what will be the size of the unit. Heating occupies one of the first places among the multiple construction stages in the construction of a suburban or major country house. Let's look at the subject of discussion in more detail - we will find all the answers.
The installation of the heating system is the most important component of future comfort for us, our loved ones. According to world statistics, half of all purchased heating systems are powered by gas.

Today, a wide range of gas boilers for domestic use is presented on the market. These modern systems are able to provide our home with hot water all year round, they can be set to "winter" or "summer" mode. A compact wall-mounted boiler is suitable for a small house, and a powerful floor unit can heat a huge living area. For uninterrupted operation, the boiler should be periodically inspected and, of course, strictly follow all the rules when installing it.
Each type of boiler has its pros and cons, but if you choose the right one, you can always find an option that perfectly suits your needs. As for the manufacturer, you can pay attention to world-famous, well-established companies such as Bosch (BOSH), Ariston (Ariston), Beretta (Beretta), Electrolux (Electrolux), Buderus (BUDERUS), BAXI (Baxi) , others. Also, do not deprive domestic companies of their attention; Lemax, Aton, Proterm companies produce high-quality heating equipment.

Wall mounted gas boilers for heating
These boilers are single-circuit or double-circuit. If you already have central water supply but no heating, buying a single-circuit boiler will be relevant. Wall-mounted gas boilers for heating a house, double-circuit, are a very good option, as they perform a dual function. The first - the heating system water is heated, maintained at the required level, the second - it is heated for household needs. Such units do an excellent job of their task, their power indicator varies from 12 to 35 kilowatts, they can provide heat to a room of up to 400 m². As for the speed of heating the water, the compact wall-mounted version is absolutely not inferior to a gas column (9-12 l / min).

Among the models on the market from well-known manufacturers, you can always find a double-circuit gas boiler for heating a private house. Wall options can be installed in any room (kitchen or bathroom), they do not take up much space, have an attractive modern design, low weight. The pricing policy of this equipment is very loyal. Despite the fact that the installation of a wall-mounted boiler is not particularly difficult, it is still better to entrust this work to gas professionals. The water heating mode of modern wall-mounted boilers is flowing, but it depends on the model, that is, the combustion chamber can be open or closed.

If the gas boiler will be placed separately, that is, it is necessary to allocate an isolated room for it, then it is more advisable to choose a model with an open chamber. If the unit, for example, is installed where there is no chimney, then it is better to opt for the option with a closed combustion chamber.
Automation is responsible for the workflow, thanks to which you can maintain the required temperature regime inside the house. Using the timer, you can set the required temperature for a single room or for a specific time period. If you plan to equip a "heated floor" in a private house, it can also be connected to this heating system. In the absence of gas, the wall-mounted boiler switches off automatically, and, likewise, turns on when it arrives (automatic ignition). The automation of the device is also responsible for the presence of draft chimney.
Modern models continue to work even with significant differences in gas supply. The power of the burner can be changed depending on the need, the presence of the required degrees of protection allows you to use all the advantages of the boiler without fear. Some devices are equipped with a magnetic system to minimize scale, which significantly extends the life of the unit. Depending on the power indicator, the manufacturer, the brand of the product itself, you can provide heat, hot water from 50 to 400 m².
Floor gas boilers for heating
Gas-fired boilers for floor heating of a house differ in their capacity from wall-mounted models. They are able to provide hot water, warm homes with a large area. Outwardly, they fit quite comfortably into the appearance and interior of the room, since all the connecting systems, nodes are hidden inside the installation case. Such a boiler remotely resembles a refrigerator, but it has a completely opposite principle of operation.

Floor models are characterized by a long service life, provide a continuous operation of the heating system. Compared with wall options, such boilers are heavy, they need to be pre-aligned with the base on which they will be placed. When planning the installation for this equipment, a separate room is often allotted, this is done for the convenience and safety of the operation of the gas unit. Such boilers require an appropriate chimney - unstrained and not having more than 2 elbows. They are reliable, easy to operate, have an automatic system to maintain the required temperature conditions, they themselves turn off if the gas supply stops or there is no draft, the efficiency is 90-92%.
Floor-mounted gas boilers are double-circuit or single-circuit, as in the case of a wall-mounted analog, some can heat the room, provide you with hot water, others can only heat the house. For a private house, it is more advisable to purchase a two-circuit option, it will provide you with water and heat, minimizing energy costs. Double-circuit gas boilers for floor heating of a house can heat water, both in flow mode and in storage mode (as a bolera). Depending on the model, the power of this heating equipment varies from 10 to 700 kilowatts, the combustion chamber can also be open or closed, the maximum heating area of the room is from 20 to 800 square meters.
The heat exchanger for floor boilers can be steel or cast iron. Cast iron is usually thicker, but more vulnerable (the formation of microcracks, destruction due to overheating). Steel analogues are much more practical, more reliable. Burners in such boilers can be atmospheric or inflatable (fan). Atmospheric burners are quiet operation, simplicity, lower efficiency compared to inflatable. Boilers with inflatable burners are more expensive, their capacity can be several thousand kilowatts. A unit with a atmospheric analogue has a power of 10 to 80 kW. Thus, according to your individual needs, you can choose the best option for your heating equipment.
These units can have one or two power levels (single-stage or two-stage). And they are also endowed with the ability to smoothly control this power (modulation). At full capacity, a private house is heated using an outdoor gas boiler approximately 20% of the time from the entire heating season. That is why you should look at the two-stage boiler models - this option is more profitable, more economical.
Gas heating of a private house provides for the individual development of a heating system, this issue is decided at the stage of calculating the building plan. When choosing a gas boiler, the entire area that it will provide heat is taken into account, all the nuances. Sometimes you can observe the so-called combined options - a floor boiler for heating rooms and a mounted unit to provide dwelling with hot water (installed in the same house).
Gas boilers for heating a private house, how to choose, what parameters should I pay attention to? Based on the above information, the main selection criteria can be distinguished: the type of equipment itself, power (with a control range), fuel consumption, type of burner, tank volume, type of heat exchanger. Approaching the choice of the unit correctly, thoughtfully, you can get the best option, solve many problems.
