What is an electric storage heater?

Also known as night storage heaters, electric storage heaters warm up your house whilst making the most of off-peak electricity prices. They store thermal energy by heating up internal ceramic or clay bricks at night when electricity tends to be off-peak and cheaper. This heat is then released during the day to keep your house warm.

How much electricity does a storage heater use?

And, they'll leave your home nice and clean. When charging heat, a small electric storage heater may consume about 1kW, while larger models might use nearer 3kW. That’s a lot of electricity – but remember it’s the maximum amount of power it’ll use. And some storage heaters stop using energy when they’ve stored enough heat.

Do storage heaters use off-peak electricity?

During the night, the storage heater uses off-peak electricity (could be Economy 7) to heat up and store the heat in the bricks. This is then released during the day to heat your home. Are storage heaters worth getting? Most storage heaters are 100% efficient because all the electricity they use is converted to heat.

Are storage heaters energy efficient?

Storage heaters are energy efficient as all the electricity they use is converted into heat. However, electricity tends to cost more than gas, meaning that electric heating can be expensive. Choosing a tariff that charges you less for electricity at off-peak times will be more cost effective.

How does a storage heater work?

Older storage heaters use input and output dials to control heat. The input controls the electricity – the higher you set it, the more electricity it will use and the more the heater will heat up at night. The output dial controls the release of heat – the higher you set it, the quicker heat emits from the heater.

How do you store energy?

You can store electricity in electrical batteries, or convert it into heat and stored in a heat battery. You can also store heat in thermal storage, such as a hot water cylinder. Energy storage can be useful if you already generate your own renewable energy, as it lets you use more of your low carbon energy.
