Central heating is a way of providing warmth in your home from, as the name suggests, one central source.
With a ‘wet system’ hot water circulates through a system of pipes that connect to the radiators throughout a house. At the centre of the system, a boiler burns a fuel – or sometimes there is a ‘heat exchanger’ and this heats the water that feeds the network of pipes. ‘Wet systems’ are the most popular form of heating system in the UK.
Radiators, despite their name, do not just give off radiant heat, in fact they deliver most of their heat through convection; air warmed by the radiator naturally rises, and cool air falls relative to it, as a result the warmed air circulates and the ‘space’ in a room is warmed.
As well as taking care of your heating needs, combi boilers provide instant hot water. They have the advantage of freeing up space in a home, because there’s no need for a hot water cylinder (tank) like there is with a conventional boiler.
