  24. HVAC Auxiliary Heater Application Basics • new diesel and gasoline combustion engines achieve such a good overall efficiency, that the needed, dissipated heat to warm up the inside of a car is far too less • auxiliary heater systems generate additional heat by either:1) heating the cooling water of the engine, or2) heating the incoming air • today are electrical and combustion systems available • the future trend points clearly towards electrical heater systems since they offer the following advantages:1) less weight2) smaller size3) higher reliability
