Have these heaters for occasional heating indoors at work, or at celebrations. Gas heaters make the air then too bad, or you have to ventilate and then it picks up again. But they are very well suited. They are built quite robust and the coils also glow not to himself but remain Wore dark when heating. This Trotec TDS 20 is almost completely identical to the Einhell IH 3000, which, however, still an additional thermal switch has top of the housing, through which the fan automatically starts up again when the temperature in the housing takes on a higher value. This occurs when the heater is provided directly from the full heating at switch to "Off". Then the Einhell jumps another - twice on cold airing. Whether this option is really necessary remains to be seen? After all, who considered a little, makes the heater when parking anyway only briefly on cooling (ventilation without heating) in order to protect the device. The rear Ticker exhibits the thing and also pulls the plug out equal. Then the additional thermostat Einhell brings nothing more. It then flaring but also nothing from, but cracks box but just as though to himself. The case seems not particularly protected against corrosion. For my purpose, the heater is well suited.
