They’re claiming that this here Radiator Booster product will cut your heating bills by up to 10%. How? Well, you plug it in, stick it behind your radiator and watch amazed as two miniature 12V electric fans suck warm air out from behind the rad and push it into the room more efficiently. Apparently it costs 30p a year to run, and reduces heat loss through walls and everythang. Sounds good to us. £14.99.
How much energy does it really save? This will depend on how you use the Radiator BOOster, and for how long. But 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 more than 2 degrees reduction.
