Electric Storage heaters or night storage heaters as they are sometimes called, charge up at night by taking advantage of off-peak electricity rates on Economy 7 & 10 tariffs. Once charged they release their heat during the day. Storage heaters have ceramic or clay bricks in side them which heat up overnight and then this heat is released gradually during the day.

​

Most storage heaters are wall-mounted and will have 2 dials on the top; one for input and the other for output. Newer models will also have digital displays. 

​

To operate storage heaters you must set the input in the evening to the expected heat release of the next day. If it is not particularly cold then there is no need to set to maximum as this would waste energy. Most storage heaters will only charge at night time so they can take advantage of the cheaper electricity but some do have a 'boost' button but this would use the more expensive 'day' rate. 

​

The output dial is used to regulate how quick the heat is released by the storage heaters, the higher the setting the quicker the heat is released.

Modern Storage heaters

​

The latest Electric Storage heaters are much improved on the previous models and can have significant savings on older models. The new modern High heat retention Electric Storage heaters are also smaller and more compact that the older models and you can also purchase 'Solar enabled' Storage heaters that also take advantage of Solar PV during the day.

​

It is possible to have Electric Storage heaters installed under the ECO4 scheme if you own your home and you have older heaters present or if you have no heating, electric room heaters or old electric storage heaters & have Solar PV installed as well then they can be installed in owner occupied or rented properties.
