How does a central heating system work in a house?
A central heating system consists of a boiler, heat pump or furnace. The furnace contains several parts, including burners that deliver and burn fuel, a blower, heat exchangers, a blower and a flue. The furnace will push air through the heat exchanger. Then, it will pump the warmed air through your air ducts to distribute heat throughout your home.
In the summertime, a central heating system can also provide air conditioning to cool and dehumidify your home.
