Electric boilers work under a similar principle as traditional gas boilers; however instead of requiring fuel to heat the water in a central heating system it uses electricity. Also available as an electric combi boiler, these heating systems offer great space economy as they combine the water heater and central heating boiler into one unit.
Installation is simple and cost effective due to their compact and light construction, and because they are powered by electricity they don’t require a flue or fuel supply. An electric boiler can therefore be sited anywhere within the property which makes them ideal for homes that don’t have the extra space for storing an oil tank. The electric central heating boiler is also suitable for properties which have no access to mains gas supply or experience gas boiler restrictions.
The size of the property and the heating requirements will determine what kilowatt output is needed. The lower kW boilers are cheaper to buy and have considerably lower running costs, however these may not be as efficient as larger models. Electric boilers are not suitable for homes of a larger size or properties with high demands for hot water. This is due to the limitations in the amount of water that can be heated at any one time.
