2020/8/26 · A boiler is a type of central heating system. Heat is generated as the boiler does its job—boiling water in a tank, which is then dispersed throughout a building. Boilers heat and then pump water or steam through pipes in a home, and as the steam or hot water passes through the baseboards, radiators or radiant floors in the rooms of a house, the heat is released, raising the temperature in

Gas-fired steam. 80% AFUE. Oil-fired steam. 82% AFUE. Oil-fired hot water boilers. 84% AFUE. The higher the AFUE rating, the more efficient the heating system, and the less energy needed to heat your home. For example, a new, high-efficiency furnace with a 94 percent efficiency rating provides 94 cents worth of heat from every energy dollar. By

Ventilation—More circulating air is required for the boiler room than for a habitable room, to reduce the heat buildup caused by the boiler or furnace and to supply oxygen for combustion. Fire protection rating —As specified by various codes (fire code, building code, and insurance underwriters), the fire regulations must be strictly adhered to in areas surrounding the boiler or furnace.
