The PTC (positive temperature coefficient) heater is simply an electrically heated matrix that sits in the airflow from the interior fan and, when the incoming air is cold, generates heat and warms the air passing over it, which then goes into the car interior. It is designed to be a short term heating method that provides some heat in the few minutes between starting the engine and the coolant providing warm air. This can be very useful for clearing windscreens of ice etc. as the air is slightly warmer than outside air. We are talking "slightly warmer"" here, not a blast of tropical magnitude. I don`t know what the heater is rated at, but if you consider that a 1KW heater would draw at least 77 amps from the alternator, I guess it isn`t very generously rated.

its also fully automated too, as the thread with my rather boring temp gauge and stopwatch videos showed that it heated the same whether the PROG button was pressed or not
