Chat OnlineJan 18, 2017 · A central heating system uses some form of energy combustion or release, be it from a furnace or furnace and boiler combination. What are furnaces and boilers? Essentially, a furnace or boiler is the mechanism that produces the heat that your central heating system will then distribute to keep your home warm.
Chat OnlineSpecifically, AFUE is the ratio of annual heat output of the furnace or boiler compared to the total annual fossil fuel energy consumed by a furnace or boiler. An AFUE of 90% means that 90% of the energy in the fuel becomes heat for the home and the other 10% escapes up the chimney and elsewhere.
