Install Central Heating pages:
Most homes today have some form of central heating. The system will usually cater for warmth and hot water for a household. There are many varied types of central heating systems some are more energy efficient than others and we have outlined the different types below.
Currently, the Building Regulations require all boilers of whatever type to be high efficiency (usually known as condensing boilers). This means they extract more heat from the fuel and therefore cost less to run to achieve the same amount of heat.
This consists of a boiler heating radiators and a hot water cylinder. The hot water cylinder is normally fed from a cold water tank in the roof space and holds enough hot water for a day's use but if needed it can be reheated from the boiler or an independent immersion heater.
Similar to traditional boilers but also include a pressure vessel within the boiler. This means that the system is filled from the cold water mains rather than a small header tank in the roof space.
This is two appliance in one, a boiler to heat the radiators and an instantaneous water heater for the hot taps. It does not need a cylinder to store hot water because the water is heated only when a hot tap is turned on. The main advantage of this type of boiler is that the hot water is at the same pressure as the cold water and no tanks are required in the roof space. If the combi is fitted close to the hot taps it will be more efficient than in a storage system
Most homes have access to mains gas and a gas boile system is generally the most cost efective way to heat a home. Where gas is not available, LPG, electric, oil fired or solid fuel boilers could be used but these will be much more expensive to run. This may be an opportunity to look at some of the renewable energy systems.
