What is home furnace?
Furnaces. A furnace works by blowing heated air through ducts that deliver the warm air to rooms throughout the house via air registers or grills. This type of heating system is called a ducted warm-air or forced warm-air distribution system. It can be powered by electricity, natural gas, or fuel oil.
Do all houses have a furnace?
Heaters, Furnaces, And Boilers are all connected Most homes have a boiler and a furnace to some degree. The furnace is the primary source of central heat, pumping hot air into every room and kicking the cold to the wayside.
