How Central Heating Works How Central Heating Works
Modern homes often benefit from the installation of central heating but how does it work?
Central Heat Source
As the name implies, home central heating uses a single source of heat and then distributes that heat throughout the parts of the house that need it.
The Furnace or Boiler
The heart of a central heating system is the furnace or boiler. The furnace contains the heat source and applies it to the heat distributor (air or water).
Air Pump - An Open Air System
Once the heat distributor is in use it is circulated by a pump. The circulation of air is achieved by a system of ducts that carry the hot air through all the ducts that are available. Ducts can be closed where heat is not required. The air is not a closed system so new air is being drawn into the system all the time it is operating
The circulation of water is also driven by a pump but the water is driven through pipes that connect strategically placed radiators. In areas where heat is not required the radiators can be closed. Radiator central heating systems use a closed system so the same water is circulating all the time. The system is connected to a supply of water so that losses through evaporation are replaced automatically.
Home central heating can seem quite complicated but the basic idea is quite simple really.
