Claire's Eco Store is proud to sell the Radiator Booster Mk2. We are official stockists of this product and are the only store in the UK to have received limited edition colours of the Radiator Booster. The Radiator Booster is an INGENIOUS TELESCOPIC DESIGN with THERMOSTATIC CONTROL. Radiator BOOster™ is an Innovative, inexpensive, ECO-FRIENDLY product that can heat your room faster, and save energy at the same time, reducing your heating bills. Simply place the Radiator BOOster™ on the top/rear of a standard domestic water filled radiator, plug it in, and away it goes. This ingenious and clever design uses a miniature 12-volt electric fan to suck the heated air from behind your radiator, firing it into your room far quicker than any natural convection. Help save the planet and cut your energy bills, all for a running cost of around 1p per Week. Each RB1-707-TT Radiator BOOster™ weighs only 150gms, is adjustable in length (400-730mm) and around 53mm square. Each unit comes fitted with a 1.8m lead, however a 3m extention lead EL-RB1 is available seperatly, please see my other listings for this item. UK energy providers state that reducing your thermostat setting by one degree Celsius could save the average home £49/year or 10% of your heating bills. Most tests carried out with Radiator BOOster™ have achieved at least 2 degrees reduction. This ingenious device works in 2 ways; 1) Your central heating boiler will use around 15 kilowatts of energy every hour (some even more). The clever fan arrangement within the Radiator BOOster™ draws heat from your radiator, heating your room in up to half the time, allowing your boiler to shut down much sooner. If you could save just one hour a week of your boiler working, you would save 15 kilowatts of energy. You could easily find the savings more than this, between 7 and 14 hours/week (over 100 kilowatts) during the colder months is typical. 2) As your radiator heats up, the ‘rear’ surface normally radiates heat onto your wall, heating this up, which in turn is lost through the wall structure due to conduction. The Radiator BOOster™ sucks most of this wasted heat away from the wall and fires it into your room, significantly reducing the losses, saving you even more energy. It really is as simple as that! A great winter product that is proven to save you £££'s
