What is a Boiler?
A boiler is an enclosed vessel in which water is heated and circulated, either as hot water, steam, or superheated steam for the purpose of heating, powering, and/or producing electricity. The furnace of the boiler is where the fuel and air are introduced to combust; fuel/ air mixtures are normally introduced into the furnace by using burners, where the flames are formed. The resulting hot gases travel through a series of heat exchangers, where heat is transferred to the water flowing though them. The combustion gases are finally released to the atmosphere via the stack of exhaust section of the boiler.
Boilers as well come in standard and high efficiency. Sometime choosing the right boiler can increase the square footage of your house since the chimney can be removed which also can increase your property value.
