The product works by the use of a fan which automatically switches on when the built-in thermostat reaches a set temperature. It is possible to hear the fan running quietly and you can feel the warm air being blown out from the Radiator Booster if you put your hand nearby. Whilst it isn’t possible to accurately measure how much energy the product saves, it is logical that the action of the fan will help to heat the room more effectively which should in turn save energy.
I would suggest that the Radiator Booster is a great product to use in your most-frequented rooms which are usually those with radiators set to the highest temperatures. At around £19 each, the initial outlay for these products could add up if you were to buy them for a number of radiators, but, according to the packaging, they could pay for themselves within two winter months.
