Storage heaters information

Electric storage heaters work by storing heat overnight and then releasing it gradually throughout the day.

You should run storage heaters on the Economy 7 tariff. This means they'll use electricity supplied at the cheaper night-time rate. Get in touch with us if you'd like to check the exact times for your meter.

You'll need to get a qualified electrician to wire the storage heaters into your meter. Each one should have a separate on and off switch on the wall next to it.

Basic storage heaters

Basic storage heaters have two main controls – an input and an output (or boost control). You'll probably find these at the top of the heater.

You can control storage heaters individually, so each room can have its own setting. 


You use the input control to set how much heat the heater stores. It's best to keep it on a lower setting in milder weather. When it gets colder, choose a higher setting to store more heat.


The output (or boost control) sets the room temperature by controlling how quickly the stored heat escapes.

If you're out during the day, keep it on a low setting. Save the higher setting for when you're at home.

Remember to turn it back to the lowest setting before you go to bed. This will stop the heater releasing the heat that it generates straight away.

Automatic storage heaters

Automatic storage heaters have input controllers. These have in-built sensors to monitor the air temperature whilst they're storing heat.

Once you find the heater setting that keeps you comfortably warm, you won't need to change it. The heater will automatically adjust its charge to match your setting.

Fan-assisted storage heaters

Fan-assisted storage heaters blow warm air into your room from the bottom of the heater.

Some models have a two-speed fan to control the output of the heat.

Keep it on a lower setting for normal use and use the high (or boost) setting to heat the room quickly.

Combination storage heaters

Combination storage heaters have a built-in convector that runs separately on the day rate. This is useful in cold weather.

Try to only use this when necessary so that you make the most of your cheaper stored heat.
