The SpeedComfort is extremely energy-efficient. With an average usage of 1,200 hours per year, SpeedComforts cost less than €0.32 in electricity (0.55 Watts). Thanks to the loss-free adapter (12 volts), you consume nothing when it’s turned off—unlike a standard adapter, which can cost you around €12 per year! The sensor measures when the heating reaches the desired temperature, so SpeedComforts automatically turn on and off, never running unnecessarily.
