Video at Amazon.com View the heater I have now for about a year. Initially used in the bathroom (approx 8sqm), the same later on changing to warming. This he actually ran every day. The result after one year: It continues to make a very good and reliable work as the first day. In detail: The heater has everything you can expect from a modern heater: A thermostat with antifreeze, two Heizsstufen, a ventilation stage, a rollover protection and overheat protection. The heat output is consumed 1850 watts well in stage 2, the measured it from me. Level 1 (ca 950 Watt) I find less useful - but that is more to the personal preference, because I need it fast good warm. The volume is pleasant and not too loud, 50-52 dB of me measured. Even after a year, the fan runs quietly, the camp does not sound out of round, but after running like clockwork - particularly here, the heater differ in quality. My conclusion: For a good price you get as good a performance that still reliably nicely warms daily even after 12 months.
