These powerful, energy-efficient fans are designed to spread the warm air generated by your radiators faster and more efficiently throughout the room. The result? A uniformly heated space and a lower energy bill! The silent radiator fan is suitable for all radiators and convectors and can be installed in an instant. With Heatfan, you can save significantly: about 15-20% with outliers of up to 30% on the amount of gas for heating your home. The Heatfan 4 Duo is suitable for radiators/convectors from 80 to 140 cm. Advantages of Heatfan radiator fans Universal, fits every radiator/convector Save up to 30% on your gas costs immediately Highest quality fans, no noise All Heatfans are modulating and adjust speed Heat is distributed faster and more efficiently in the room Easily adjust speed to your personal preference How does the Heatfan radiator fan work? The radiator fan accelerates the airflow along the radiator by blowing. This causes more cooler air to flow along the radiator, which heats up faster. The Heatfan turns on automatically at a radiator temperature of approximately 24.3°C and off at 25.3°C. The Heatfan consumes very little power, a maximum of 1 kWh per year. This amounts to about €0.25 per Heatfan per year. The Heatfan's sensors switch off the fans at the desired room temperature. With the built-in modulator, the fans will rotate faster and slower, depending on the temperature. With the increase in airflow and circulating heat, the thermostat will turn off earlier, and relatively less energy will be consumed. All Heatfan components are developed with a minimum lifespan of 50,000 hours. This means that if the Heatfan is in continuous use 50% of the time, the radiator fans will last 11.5 years. How quiet are the Heatfan radiator fans? The Heatfan is super quiet, under 20 dB. For comparison: a ticking clock makes 30 dB of noise. A falling leaf is 10 dB. How does the Heatfan Touch Sensor work? Heatfan's latest sensor features advanced technology that automatically switches off the fans when the radiator reaches a temperature of 25.3°C. The red LED light on the sensor indicates whether the fans are active. Radiators gradually heat up and slowly cool down again. Constantly blowing the fans at one speed does not take this dynamic into account and often leads to unnecessary noise pollution, cold drafts, and a fluctuating indoor climate. Modulating blowing offers a smart solution. All Heatfans are equipped with technology that automatically adjusts the blowing speed to the heat of the radiator. The touch sensor ensures that the fans blow harder when the radiator gets warmer and slow down and eventually switch off as the heat decreases. This way, the warm air is distributed evenly. The touch sensor has different settings with which you set the desired speed: 1. Green Low speed Supply temperature > 60°C 2. Yellow Low/medium speed Supply temperature 50-60°C 3. Orange Medium/high speed Supply temperature 40-50°C 4. Red High speed Supply temperature <40°C 5. Blue Maximum speed For cooling in summer 6.
