A central heating system provides heat to the inner of a building from one point to other rooms.
A central heating system most popular method of heat generation involves the combustion of fossil fuel in a boiler.
Most new housing has come with central heating systems installed. Normally use gas heaters, district heating, or a oil-fired system, often using forced-air systems.
Steam-heating systems, fired by coal, oil or gas, are also used, primarily for larger buildings.
Electrical heating systems are less commonly and are practical only with low-cost electricity or when ground source heat pumps are used.
The combination of central generating plant and electric resistance heating makes the overall efficiency less than for direct use of fossil fuel for space heating.
