I know the coolant heaters on ebay are starting to become much more attractive as the winter fuel mileage starts to plummet....

My van usually gets closer to 21 mpg, and right now I estimate it has gotten about 19 mpg this tank.......grrrrr.

A thought has occured to me. How much battery power would I need to power a coolant heater through an inverter? Running a coolant heater at the house wouldn't be a big deal, but what about at work when it sits for 8-10 hours cooling off?

Another option is to attempt to insulate the engine compartment and preserve the heat, but that is a tricky thing when dealing with how to insulate around the exhaust manifolds and tail pipe.
