Similarly, I installed a Cumins engine block heater. I plug it into shore power around December 15 and leave it on until spring. It draws 750w and keeps the engine compartment including water tanks above freezing even in the coldest Knoxville weather. Certainly beats a ceramic heater for efficiency. Heated block stays warm for hours if power is interrupted and allows us to operate year-round.
