Both the A/C compressor and the eberspacher heater are run from the high-voltage. Only the climate control fan is 12v. BTW, the heater is a 6kW unit, so it can draw up to that, it's not limited to 4.5kW.

Its amazing how inefficient the heater output is compared to the A/C. It always seems to take a great deal of time and power to get decent heat. Yet I always seem to be amazed at how little power the A/C is taking while blowing amazingly cold air. I would assume a regular ICE compressor takes more equivalent power from the engine that 250 watts or so.
