First of all, you should decide what fuel you will use to heat water in the boiler. To date, it is possible to purchase gas, electric, solid fuel and liquid -fuel boilers. Gas boilers are most popular. I mounting a set of nozzles and spare parts enables the boiler to work both on natural and liquefied gas. Having mounted the kit, it is necessary to configure gas reinforcement and automation.
There are wall and floor gas boilers, but today are more often used by wall gas boilers. Their advantage is compactness. They will not take up much space. This equipment does not require the installation of bulky chimneys, which removes combustion products through the exhaust in the wall of the room. The disadvantage of wall boilers is that they cannot heat large rooms, so if you have a large living space, it is better to opt for floor boilers.
The efficiency of liquid -fuel boilers, to some extent, is more than that of gas boilers, but their operation is more expensive. In addition, they need special containers in which fuel is stored.
Electric boilers are small, which allows you to install them almost anywhere. The operation of an electric boiler is silent thanks to electronic launch elements. Installation of an electric boiler does not require additional wiring (for example, gas). It does not need a chimney and an additional room for the boiler room, which significantly reduces expenses.
In the case when there is an opportunity to cheaply purchase such solid fuel as peat, firewood, coal or coke, then there is an occasion to buy a solid fuel boiler. However, such a boiler compared to other types of boilers will require more time and attention to maintenance. Automatic fuel supply and ash removal in them are excluded.
Combined heating boilers will come in handy when it is required to replace the type of fuel. Such boilers require large costs than those that work on one type of fuel.
Having decided on the type of fuel, you should think about whether your boiler will be intended only for heating the room or whether it has to provide a house and hot water supply. In Ttorm, you should stop on a double -circuit boiler.
Single -circuit boilers differ from double -circuit in that they have one contour (with hot water) for heating. To establish hot water supply, you need to install a boiler, and only then connect it to the boiler. In double -circuit boilers, one contour is intended for heating, and the other for hot water supply.
It will not be superfluous to find out the necessary power of the boiler. To do this, clarify several nuances: what is the area of the heated room, how well the house is, what is the size and characteristics of the windows and whether other consumers of thermal energy exist. The heat engineering calculation of the building will help to choose the power of the boiler with greater accuracy. If you look approximately, then at 10 kV meters of heated area (ceilings not higher than 3 m) accounts for 1 kW.
