7. SpeedComfort 2.0 Duo set radiator booster 50-120 cm
The intelligent radiator fan saves up to 22% energy. SpeedComfort provides radiators with more power and accelerates convection. This way, you receive more heat from your radiators, the room warms up much faster, and better heat distribution is achieved. As a result, the thermostat turns off more quickly, and the water temperature of your boiler can be lowered, saving energy. The Basic Duo Set is the ideal starter kit if you have a standard radiator that is between 75 and 120 cm long. The set includes two SpeedComfort units, an adapter, and a smart thermostat sensor that automatically turns the SpeedComforts on or off.
SpeedComfort Starter Set Duo:
Smart radiator booster fan for heaters with a minimum plate gap of 70 mm for mounting under the radiator. Depending on the length of your radiator or convector, you can attach multiple SpeedComforts to your heating system. In an average-sized living room, you will need about 3 to 5 SpeedComforts. With the included 30 cm connection cables, additional SpeedComforts can be connected.
How the radiator fan works:
Through enhanced air circulation and improved heat distribution, a pleasant and even room climate is created about twice as quickly in your home, providing greater living comfort. The energy-efficient radiator fan improves air circulation in the room through its blower, thereby increasing heating performance. This allows you to use your energy supply more efficiently and significantly reduce your heating costs. Once installed, you can enjoy worry-free operation. The SpeedComforts are automatically turned on and off. This is managed by the smart sensor, which is not visible behind the control panel. Due to the lossless adapter, the SpeedComforts consume no power when turned off.
