The Warmroom is the latest invention from British manufacturer Anchor Magnets. The Sheffield-based company was set up in 1984 and is run by Mike Burton.
The Warmroom flexible radiator magnets can be cut with kitchen scissors to fit to the back of any steel radiator and reduces the amount of heat escaping through walls by up to 60 per cent, according to tests by the University of Sheffield. The strip has been trialled by South Yorkshire Housing Association and National Energy Action.
Here’s how it works: heat usually radiates to the wall and then escapes outside. With Warmroom attached to the rear of the radiator, heat is prevented from radiating to the wall because the emissivity of the strip’s shiny surface is very low. Simple but clever.
The Warmroom strip is permanently magnetic so it lasts forever and can be removed and reattached to another radiators if needed.
“The colder it is outside, the better the product works and it is really effective in preventing heat loss in houses, schools, hospitals, offices in fact any building heated by steel radiators mounted on outside walls,” says Burton.
Anchor Magnets employs 30 people and turns over £4m.
