The best devices for heating a private house are single-circuit gas boilers
The availability of natural gas even in the most remote corners of the country has led to the use of this energy source for heating private homes.
Single-circuit boilers operating on natural gas, heat the room evenly. And if we compare them with dual-circuit ones, the former are more economical and more convenient in terms of installation and assembly.
Types of single-circuit gas boilers for heating a private house
By installation method:
- Wall mounted: They have medium power and are wall-mounted, compact.
- Floor: require special installation, are highly powerful, durable, and mobile. They have an autonomous mode that allows the device to operate while a person is away from home.

According to the principle of using thermal energy:
- Convection: air-gas mixtures are burned, releasing heat, which is used to heat the room.
- Condensing: An additional heat exchanger is responsible for thermal energy.
Important! When using convection boilers, it is worth remembering that some of the thermal energy will be lost during operation, since it will be burned together with the combustion products in which it is contained.
Operating principle of the device
The gas boiler consists of expansion tank, circulation pump, valves And other details.
Devices do not require any additional modifications, as they are equipped with everything for comfortable use and satisfactory operation.
Photo 2. Diagram of the device of a single-circuit gas boiler. The arrows indicate the components of the heating device.
Scheme:
- The device has built-in sensors, which calculate the ambient air temperature and send a signal to the boiler. This signal shows how much heat is needed to heat the room.
- The water in the device reaches the set temperature via a burner. And is pushed out built-in pump.
- When the temperature reaches the desired level, the boiler will turn off automatically, until the temperature starts to fall again.
Main technical characteristics
Power — the most important characteristic by which a single-circuit gas boiler is selected. Usually it is from 12 to 45 kilowatts. The area of the heated room depends on it. At maximum power, the area will reach 250 square meters. And also the speed at which the room will be heated.
Combustion chamber type:
- Open: For such a combustion chamber, a vertical chimney is purchased, since the removal of all products and their disposal occurs naturally - gases that have already been processed will exit through the chimney.
- Closed: here, on the contrary, the disposal occurs by force, since an additional turbine is built into the device. The coaxial chimney helps to circulate the air.
Heat exchanger type:
- Bithermal: has two contours, one of which is located inside the other, they are cheaper, but break faster.
- Monothermic: has two contours, which are located at a certain distance from each other, their service life is longer because of this.
Recommendations for selection
By manufacturer, boilers are divided into:
- French. Such heaters are considered if they are in the middle price category, but with excellent quality. They are powerful, the cost reaches 50 thousand rubles.
- Russian. The domestic manufacturer offers similar boilers, the price of which is only 15-20 thousand rubles. Wall-mounted boilers are worse in quality, while floor-standing units are not inferior to foreign brands. However, they are much cheaper.
- Czech and Italian. Can be purchased for 30 thousand rubles. Better quality than domestic ones, but inferior to French ones. Although significantly cheaper to maintain.
- German. The best quality boilers. However, they are also the most expensive, about 80 thousandSuch heating devices will last a very long time.
Also, when choosing, the following factors are taken into account:
- Floor-standing boilers are noticeably more powerful than wall-mounted ones and heat a large area.
- Some devices should not be left unattended for long periods of time.Therefore, if you want to heat a country house where you live only at certain times, make sure that the boiler will work without you.
- Some types of boilers are subject to corrosion, For private homes this is a huge problem.
- Attention is also paid to the type of combustion chamber. Devices with an open chamber will be cheaper. However, this is a disadvantage for several reasons, the first of which is environmental. With an open chamber, you have to think about where the smoke will go. And this is additional effort.
- For residents of rural areas where gas has not yet been installed, It is important to pay attention to the permissibility of useThe device must be equipped with the ability to operate on liquefied gas.
- Don't forget about the self-diagnosis function, which is not present in all heaters, but it is very important. If there are any problems with the device, the device itself will determine what is wrong. By overpaying for this function now, you can save in the future on a technician who will charge money not only for repairs, but also for diagnostics of the boiler.
Features of operation
If there is not enough time to take care of the device, then choose wall-mounted boilers. Such devices are easy to maintain and can be used immediately after installation. Floor-standing ones require additional care.
Attention! Don't forget to connect all devices to the gas main during installation. This is the most common mistake during installation.
Rating of the best boilers
- Baxi Luna 3 Comfort.
The price of these boilers varies greatly and ranges between from 40 to 100 thousand rubles. But, despite this, the efficiency of any of the devices exceeds 90%, and this is an advantage over other devices.
Boilers of this type are predominantly wall-mounted and have a closed combustion chamber. The device is protected from pump blocking and overheating (automatic shutdown upon reaching a certain temperature), which is not available in every device. Power 30 kW.
- Leberg Flamme 24 asd.
The heating device is worth it 35 thousand rubles. Although the efficiency is 96%, making it one of the best on the market. There are only positive reviews for this device, as it is inexpensive and works satisfactorily. This boiler will be an economical solution to problems. The heating power is 20 kW, so it will take a long time to heat a large room. This is one of its significant disadvantages. Installation type - wall-mounted. Combustion chamber - closed.
- Mora Top sa 30 e.
Price - 60 thousand rubles, efficiency — 92%, which is inferior to the previous heater. The heating power varies depending on the model from 18 to 25 kilowatts, so it will also heat the room for a very long time.
The installation is floor-standing, the combustion chamber type is open, which is also a disadvantage in some ways.
Since floor-standing units heat the room less, and temperature fluctuations may be noticeable in different parts of the room.
- Viessmann Vitodens 100.
Price varies up to 100 thousand rubles, average efficiency 98%. This is a huge plus, but the price for it is noticeably high, which becomes the main problem. The power is about 19 kilowatts. Installation is wall-mounted, combustion chamber is closed.
- Viessmann Vitogas 100-F GS1D870.
The price for this heater is inflated and amounts to 108 thousand rubles. Efficiency - about 92%. The combustion chamber is open and the installation type is floor-standing. It wins over other models only in power (30 kW). Withstands high thermal loads in 35 kWEquipped with overheating protection.
