Right now the electric coolant pump (the key to warming the engine with out running it) is powered with the key switched on.
What ever you do don't turn the key off with the coolant heater on. It makes some weird noises. I am lucky I did not burn it out.
This is exactly why I am building a power supply to run the coolant pump with 240 volt AC power when the coolant heater is plugged in.
