With frosty nights upon us, this Radiator Booster (as seen on Dragon’s Den) should be on everyone’s shopping list. The booster uses a small fan to spread heat more effectively around your room, warming it up in half the usual time. Your boiler will then shut down quicker – saving you as much as £140 per year in heating bills. At just £24.95, the Radiator Booster is a small investment well worth making. Get yours here.
