Most electrically heated homes in the UK have storage heaters. These use cheaper off-peak electricity to heat up during the night, and then release the heat into the home during the day when it is needed.
High heat retention storage heaters
Modern slim line storage heaters are better insulated, so are more able to store heat – that can be used when you need it, rather than leaking heat constantly throughout the day. Their heat output is more controllable, and often fan assisted, so you can heat a room up faster or keep it cool if you’re not using it. They vary considerably in price, but expect to pay around £700 each.
Automatic charge controls
Modern controls on storage heaters allow you to set a thermostat so that the heater switches off when it has reached a certain temperature. A heater with automatic charge controls will automatically control how much heat it stores overnight, depending on the heater’s internal thermostat as well as changes in daily weather patterns.
A system with Celect-type controller will monitor heaters in all rooms and automatically control how much heat is stored or released in different rooms.
