Central heating systems generate heat by transforming the chemical energy in fuel into thermal energy and transferring that energy to air, water, or steam, which then gets delivered throughout the building. The most common include: • radiation systems (hot water or steam), •
In a typical unvented system, incoming cold mains water is heated either directly in the cylinder (the 'pressure vessel') by means of an electric heater, or indirectly from your central heating boiler. When you open a tap, the hot water stored in the vessel is forced out by the incoming cold water, hence you get hot water at mains pressure.

A single boiler heats up water that is pumped through pipes to radiators throughout the house as well as providing hot water to the kitchen and bathroom taps.
Steam heating long predominated in the North American continent because of its very cold winters. The advantages of hot water, which has a lower surface temperature and milder general effect than steam, began to be recognized about 1830. Twentieth-century central-heating systems generally use warm air or hot water for heat conveyance. Ducted
Hot water heat is provided to a building by a heating boiler that heats hot water that in turn circulates through heat radiating devices in the building. Here we describe the operating and safety controls on heating boilers used to provide hot water heat through baseboards, convectors, radiators, and radiant heat flooring or ceilings.
