Place the Radiator Booster ontop of your radiator with the holes facing down - the fans suck the air up and push it out through the ends. A Radiator Booster can improve efficiency by as much as 50% by "sucking" the heat from the radiator and distributing it evenly around the room, in addition to reducing the heat losses through the wall behind your radiator. Cold spots are dramatically reduced and in most cases eliminated. Room warm up times are typically reduced by 50% and thermostats can usually be set 2 degrees lower. Over all a significant energy and cost saving.

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.
