Floor gas boiler blends harmoniously with the interior space
Power future boiler is calculated from parameters such as the need for hot water in the house, as well as its heat loss. Than they are higher, so, consequently, more powerful than you need a boiler.
Depending on the type of fuel boilers distinguish running:
- solar energy;
- liquid fuels, e.g., diesel, fuel oil, kerosene;
- a gaseous fuel;
- for solid fuels - peat, coal, wood;
- running on electricity;
- geothermal energy, ie the energy of natural resources.

Of all the above types of gas boilers - it is the most economical option for the private home, so we will treat them exactly.
Gas-fired boilers for heating private house: how to choose, what to look for
To accurately calculate the expected output of the boiler for heating private houses, most reliable to use the services of a specialist heating engineer. However, this option can roughly estimate their own. It is worth remembering that in the room, a volume of 30 cubic meters takes about 1 kW boiler output. If the boiler is used to heat the water, the preset parameter should increase by 2 times.
Modern boilers are safe and environmental friendliness
Useful advice! This formula is only suitable for the average room. If we are talking about heating a glazed veranda, an extension or a summer kitchen, you will need a more powerful boiler.
Another important point in the selection - the location of the boiler inside the house. There are a number of requirements, how to choose a gas boiler for heating private houses in this parameter:
- in the room with the boiler have to be good ventilation. If it is impossible to ensure the natural flow of air you will need to install a system of ventilation;
Wall mounted gas boiler in the interior of the kitchen
- gas boiler for heating private houses must be installed on the first or ground floor. In this case the premises must be another way out;
- to enable normal operation, and the room should have a good natural or artificial lighting.
Criteria for selection of the type of boiler
To finally decide how to choose the boiler, it is worth considering the following points:
- costs for additional snap - price floor of a bypass gas boiler for heating private houses It will be significantly higher if the purchase is also a pump, safety devices, expansion tank and other equipment. Additionally need to buy coaxial chimney for a gas-fired boiler;
Gas boiler must be installed on the first or ground floor of the house
Useful advice! All modern boilers are powered by electricity, so it is always necessary to provide a backup power source, if your house there are power surges. For this is well suited uninterruptible power supplies for gas boilers.
Thus, the choice of a gas boiler for heating private houses depends on the volume of the space, the presence of the chimney, and other parameters.
Features of floor and wall systems
There are two types of gas boilers for private homes: floor and wall. Each of them has its own characteristics.
Floor model boiler operating on gaseous fuels
Wall gas boilers
Wall-mounted gas boiler - a compact and convenient heating unit, which connects the heat exchanger, a gas burner, the pump, in its structure, using which can increase the pressure in the heating system, an expansion tank, measuring devices for temperature control and containment system security. Because of this, the price of gas wall double boiler for heating private houses will be higher than the floor of the system, but the benefits it will give more.
In addition to heating the house, an important function of the gas boiler is the hot water
Link in a wall gas boiler can be either forced or natural. Forced draft is good for those types of buildings that do not have a chimney - then comes in built a fan that removes the combustion products via a separate coaxial flue boiler which is mounted in the wall. If the house has a chimney, it is best to choose a model with a natural draft, it will be cheaper.
Apparatus wall gas boiler 1 - smoke exhaust fan; 2 - NTC hot water temperature sensor; 3 - stainless steel burner; 4 - Ionization flame control electrode; 5 - ignition electrodes; 6 - antiscaling magnetic device; 7 - hot water flow sensor (impeller); 8 - cold air lock / regulator excess thrust (F execution); 9 - control discharge of the combustion products (pressure switch); 10 - Safety thermostat; 11 - NTC temperature sensor is heating; 12 - closed expansion tank; 13 - pressure sensor in the heating system; 14 - 3-speed circulating pump; 15 - automatic bypass; 16 - valve for feeding and filling; 17 - safety relief valve 3 bar; 18 - control exhaust pipe (sensor)
In addition to heating, the second important function of a gas boiler - heating water. For this purpose, single-circuit or two-circuit boilers. Single loop, at the same time equipped with a separate structure, that is, boiler. Regardless of the number of circuits, the boiler is equipped with automatics, which makes it possible to adjust the mode of operation. During warmer months, the boiler does not turn on heating, and thus saves you money.
Wall gas-fired boiler embodiment
How to choose a wall-mounted gas boiler for heating private houses? Pay attention to its capacity, the number of loops, size, power consumption and other parameters.
