To choose gas boiler not so simply – it is necessary to approach this task after careful consideration because that depends on the choice of boiler, how warmly will be indoors, it will be how effective it to work. If the power of boiler is too small, it will enough not give heat. Too big power is irrational fuel usage.

Instruction
1. Determine the necessary power of gas boiler. It depends on set of factors: weather conditions, heat-insulating characteristics of your house, its dimensions. There is standard formula of determination of power of boiler – 1 kW on 10 sq.m. Actually, such ideal houses meet infrequently – when choosing power of boiler it is necessary to consider everything, beginning from climate, finishing with availability of windows with double double-glazed window and height of ceilings. The following formula will be optimum: boiler power = room space × power density of boiler / 10. Power density of boiler depends on the region – for the southern regions it equals 0.7-0.9 kW, for the central region it is 1.2-1.5 kW. For northern regions the power density of boiler reaches 2.0 kW.
2. Choose boiler type – floor or wall. It depends on what area you have for installation of boiler where you are going it to establish. At the same stage it is necessary to choose, single-circuit there will be boiler or double-circuit (that is in parallel it serves also as the water heater in the household purposes, performing function of the geyser).
3. Define what type of ignition of boiler will suit you more. There are boilers with pyezorozzhigy and with electroignition and also with the built-in automatic equipment. Piezoelectric ignition means that turning on of the boiler is made manually by means of pressing the pilot light button. When boiler it is disconnected, necessary to burn ignition match, it provides further ignition of torch. In boilers with electroignition there is no constantly burning pilot light that saves gas. Such boilers turn on automatically, at the expense of electric spark. Electric ignition has also minus – during blackout the boiler stops working. Boilers with the built-in automatic equipment without intervention of the person not only operate heating, but also provide independent adjustment of heating depending on temperature on the street.
4. It is necessary only to resolve issue with manufacturing firm of boiler. Its everyone chooses the brand of the boiler depending on the preferences and also material resources.
