EcoCalm Radiator Fan Booster 3.0 for Home Single Set, Smart Radiator Ventilator Increase the Heating Efficiency and Save Energy, Suitable for Radiators Such as TYP21, TYP22, TYP32
9.6 Easy installationMain highlights- 【Smart Eco Mode】Switch to "ECO" to activate the default setting of the electronic thermostat. In this Eco mode, the fans activate at a temperature of 30°C on level 1 and automatically deactivate at 24°C, effectively preventing both the fans and heater from overheating.
- 【Lower Noise】The radiator ventilator operates quietly with low energy consumption at L1 speed, producing noise levels below 39dB. This ensures a tranquil and comfortable atmosphere in the room, enabling you to fall asleep without any disturbance.
- 【Great Application】Either horizontal placement or inclined placement (30-60 degrees) is available which makes this radiator fan booster suitable for almost all radiators such as TYP21, TYP22, TYP32. We recommend using a single set for radiators longer than 42cm and for rooms within 15 ㎡. Please kindly read the troubleshooting part in our instructions if you have any questions.
- 【Energy Saving】The radiator fans can save energy and reduce heating costs by up to 20% through decreasing heating time and lowering the set temperature of your radiator. It also features 3 speed modes to suit different room volumes and maximise effectiveness in a variety of situations.
- 【Accelerate Heating】The 5 upgraded fans inside our radiator booster greatly accelerate heat circulation by drawing hot air from the heater, heating up to 5 times faster. As a radiator heat diverter, it ensures that hot air flows directly to the centre of room, providing you with direct warmth and even heat distribution, increasing room temperatures by up to 50%.
