How do Electric Boilers work?
An electric storage boiler utilises an electric flow boiler to heat the water and has a built-in hot water storage cylinder where hot water can be stored. The major advantage of these storage boilers is that the water can be heated during off-peak periods so that you can easily set your thermostat timer to reap the rewards of certain energy tariffs.
