A water heater is an incredibly useful installation if you need quick access to hot water in areas without a mains gas connection. These electric water heaters only require a cold water supply – water is held in a storage tank and warmed using an electric heating element.

At Toolstation, we stock a wide variety of water heaters from the trade’s most trusted brands like Zip, Ariston, Ferroli and many more. With a range of power options and tank sizes to choose from, you’ll find the best electric water heater for any installation.

Electric Water Heaters

An electric water heater is particularly popular in homes and buildings without gas central heating, or for smaller rooms where simple, quick and convenient hot water access is required – this could be anywhere from utility rooms, garages and workshops to handwash stations and washrooms.

Under Sink Water Heaters

Water heaters can be quite bulky, which is why an under sink water heater is such a popular choice for small kitchens. Offering a discreet installation in your unit beneath the sink, these tanks can dispense instant hot water into basins that wouldn’t otherwise be served by gas heating.

Instant Water Heaters

An instant hot water heater is another space-saving solution that offers even greater levels of efficiency. Also known as a tankless water heater, it heats cold water instantaneously as it flows through a heating element within the unit. With no storage tank, it takes up less room and only heats the water you use – this helps to reduce your energy consumption.
