Hello you, despite many search results here in the forum on the topic of heating I found nothing about the normal runtime or reached temperature when using a heating. In my Camry 3Liter V6 I have Webasto ThermoTop C . Only unfortunately I am dissatisfied with the heating power. After a runtime of 30 min I have an indoor temperature increase of approx. 10°. Now at 0-5° outside temperature it is still possible. But at -15° to 0°C outside temperature I am then far from an In the beginning I had only 1° more than the outside temperature, then a constipation in the petrol supply was fixed. Nevertheless, the 10° -12° more than the outside temperature is too little for me. According to the dealer, the SH OK and works normally. I have heard from others that they already sweat at 30 minutes and the heating already heats after 10 minutes. Now to my question: is the stationary heating defective (must therefore more sheep fen) or is my engine just too big, so the system is too weak? Would I be happy about any information.
