Electric Storage Heaters
Electric storage heaters, sometimes called night storage heaters, 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 contain ceramic or clay bricks that heat up overnight and then gradually release this heat during the day.
Most storage heaters are wall-mounted and have two dials on the top: one for input and the other for output. Newer models also feature digital displays.
To operate storage heaters, you must set the input in the evening based on the expected heat release for the next day. If it is not particularly cold, there is no need to set it to maximum as this would waste energy. Most storage heaters will only charge at night to take advantage of the cheaper electricity, but some have a 'boost' button that uses the more expensive 'day' rate.
The output dial regulates how quickly 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 over previous models and can offer significant savings compared to older models. The new modern high heat retention electric storage heaters are also smaller and more compact than older models. You can also purchase 'solar-enabled' storage heaters that 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 have older heaters present. If you have no heating, electric room heaters, or old electric storage heaters and have Solar PV installed, they can be installed in owner-occupied or rented properties.
