A solid fuel boiler will provide warmth and comfort in your home
The center of an autonomous water heating system is the boiler. Its main task is to heat the coolant. Typically, the boiler consists of two chambers: the first, where the combustion process takes place, and the second – a heat exchanger, where thermal energy is transferred from the first chamber to the coolant.
Boilers are single-circuit and dual-circuit. The former heat water only for heating, but if you connect an indirect heating boiler system to it, the boiler can additionally heat water for the water supply.
Dual-circuit boilers have two heat exchangers: primary and secondary. The first heat exchanger heats water for heating, and the second – for the water supply. The main disadvantage of dual-circuit boilers is that the two heat exchangers do not operate simultaneously. The primary heat exchanger shuts off when the hot water tap is turned on, and all energy is used to heat the secondary heat exchanger.
Boilers are also divided by the type of fuel used to heat the coolant. There are solid fuel, gas, liquid fuel, electric, and combined boilers.
Solid fuel boilers
The price of a solid fuel boiler is quite low. Its operation does not depend on the availability of electricity or gas in the house. However, to ensure uninterrupted operation of a solid fuel boiler, you need to regularly add fuel – firewood, peat or coal – and periodically clean the ash pan. On the website http://otopleniedomov.com/kotly/otopitelnyjj-tverdotoplivnyjj-kotel-dlitelnogo-goreniya-vidy-i-osobennosti.html you can familiarize yourself with the main types of solid fuel boilers and the features of their operation.
Gas boilers
Gas is considered one of the least expensive, and therefore the most economical, fuels for heating. The problem lies only in the gas main, which is not connected to every plot of land, so only those who have a gas main nearby are lucky enough to use a gas boiler for their premises. In addition, almost no hazardous substances or soot are released when gas burns.
Liquid fuel boilers
The supply of liquid fuel can be automated. However, this requires electrical energy, which may have problems and outages. To make a liquid fuel boiler completely autonomous, you need to have alternative sources of power supply.
Electric boilers
They are completely dependent on the availability of electrical energy in the house, so a backup boiler running on another fuel or another available source of power supply is necessary. To heat a large area, a more powerful boiler is needed.
Combined (hybrid) boilers
Such boilers are used when there are frequent interruptions in the operation of one of the energy sources: liquid fuel, gas, electricity. Combined boilers can support up to 4 energy sources.
To decide on the selection of a boiler, it is necessary to make all calculations for heat loss of an apartment or house. Based on these calculations, determine the required boiler power, and then choose the least expensive energy source.
