Electric Boilers

Heat up water for your taps and radiators on demand. Taps and radiators do not require outside hot-water tanks, so these systems are a good option for those who don’t have much space. However, because these systems heat the water as you need it – unlike gas boilers which just provide heated air throughout the house – they use more electricity.

Provide heat to your radiators by installing a storage heater. This works best for bigger homes with higher demands on hot water. Storage heating units – unlike combi boilers – do not need to activate energy supply each time they are needed; instead, they work off of stored energy that has been heated during periods of low use-time. A downside is the unit will take up more space than a standard boiler as it needs two tanks – one holding the stored hot water and another filled with cold water from the mains supply line.

These units function similar to heat-only boilers, but use less space because all of the mechanisms used for heating the water externally – such as pumps and valves – are built into the body of this unit. This means there’s no need for a hot water tank, which saves you precious square footage.

Some manufacturers will even build in a hot water cylinder (which is normally bought separately) for extra convenience when installing these units within an airing cupboard.
