These powerful, energy-efficient fans are designed to distribute the warm air generated by your radiators throughout the room faster and more efficiently. The result? An evenly heated room and a lower energy bill! The silent radiator fan is suitable for all radiators and convectors and can be installed in no time. With Heatfan you can save considerably: about 15-20% with peaks of up to 30% on the amount of gas used to heat your home. The Heatfan 3 Solo is suitable for radiators/convectors from 35 to 60cm.  Advantages of Heatfan radiator fans Universal, fits any radiator/convector Instantly save up to 30% on your gas costs Highest quality fans, no noise All Heatfans are modulating and adjust the speed The heat is distributed faster and more efficiently in the room Easily control the speed to your personal preference How does the Heatfan radiator fan work?  The radiator fan accelerates the air flow past the radiator by blowing. This causes more cooler air to flow past 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 uses very little power, a maximum of 1 kWh per year. This amounts to approximately €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 run louder and softer depending on the temperature. With the increase in air flow and circulating heat, the thermostat switches off sooner and proportionately less energy will be consumed. All Heatfan parts 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. The fall of a tree leaf is 10 dB.   How does the Heatfan Touch Sensor work? Heatfan's latest sensor has advanced technology that allows the fans to automatically switch off when the radiator reaches a temperature of 25.3°C. The red LED on the sensor indicates whether the fans are active. Radiators heat up gradually and cool down slowly. Constantly blowing the fans at one speed does not take these dynamics 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 spin slower and eventually switch off when the heat decreases. This way, the warm air is distributed evenly.  The touch sensor has different settings with which you can 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 the summer 6.
