I have been using the block heater some now that the mornings are getting frosty.
Unfortunately I do not have the instant defrost that I wanted for 2 reasons.
The electric coolant pump circulates the coolant through the element too fast and with the engine off the vent controls have no vacuum to actuate the fan selector so the default mode blows all the air out the floor vents.
But even after only 10 minutes the engine is nice and warm.
If the blower air would go to the defrost vents the heater would only need to be on for maybe 5 minutes before it would start to melt frost.

The heater element draws 23.8 amps.
