Domestic Central Heating Systems
The term
central heating refers to a method of heating a building from a central heat source; it is this which distinguishes it from various forms of localised heating such as gas/coal fires or electric storage heating located within a room. The plumber is only concerned with wet systems of central heating; however, the warm air system is very often connected to primary flow and return pipework to a hot storage vessel. A design of central heating can also be found which uses such materials as electric cable embedded in the walls, designed to warm the structure; the concept is the same as that of radiant systems heating
