What's a radiator fan and what can you use it for?
You can place a radiator fan on top of or below the heater in your house. This allows you to heat the room more efficiently. As a result, you'll save on your energy bill. In this article, you can read how much you'll save.
Start saving
With SpeedComfort and BlueBuilt radiator fans, you can save about 20% on the consumption of your heating. You can lower your thermostat with 1 to 2°C, but your room will heat up just as fast. Thanks to this, your central heating boiler won't have to work as hard. Because the fans heat up your room more efficiently, you can also lower the temperature of your central heating boiler to 60°C. Normally, it's set to 75 to 90°C. You can save up to hundreds of euros on your energy bill, depending on your house and gas prices.
How does a radiator fan work?
You can place radiator fans on top of or below your heater. The fan blows the heat faster into the room faster and evenly. As a result, your living room gets warm twice as fast. The fans turn on automatically when the heating gets warm. You don't have to do anything extra. If your radiator cools down, the fans stop automatically.
What do you need?
A radiator fan distributes 30m3 of air per hour. All the air in your room should circulate at least once per hour for the best result. You can calculate the capacity of your room by multiplying the length, width, and height of the room. A living room of 5m long, 3m wide, and 2m high is 30m3. In that case, you need 1 radiator fan. With an expansion set, you can enlarge the range to 300m3. You can connect up to 10 radiator fans to each other.
Is a radiator fan suitable for your heating?
A BlueBuilt radiator fan fits on almost every heater. The fan has slide-out magnet strips and includes matching feet. That way, you can adjust this fan to the radiator in your house. No further installation is required. You just plug the plug into the socket. Place the fan in spots where you often are, like your living room or home office and enjoy the heat right away.
