Radiator Booster has been one of the most popular energy saving devices for the last three years. 'Which' Magazine confirmed that this technology reduces energy consumption, and the much improved design of the Mk3 Radiator Booster will ensure this will be the must-have product this winter. Radiator Booster is an innovative, eco friendly product that uses a small fan to capture the heat that comes out the back of your radiator, circulating it better into your room. It will heat your room faster, save lost energy, and reduce your heating bills. (As seen on Dragon's Den) Simply place a Radiator Booster on top of a standard domestic radiator, plug it in, and away it goes. It'll heat your room more quickly, allowing the boiler to shut down sooner, saving heating time and cost by as much as 50% - all for a running cost of about 30p a year. This new model has a built in thermostat, a quieter fan and could save an average household between £70 and £140 per year. Also available: 3 metre extension cable.
