DerBenz,

Why would you run an electric heater all the time when you have all the free heat from the engine once it warms up.

I could see running the electric heater when the engine is cold and until it warms up, but to run the electric heater is wasting a lot of energy and putting a strain on your alternator.

A little plumbing to your cooling system will heat your WVO fuel for free.
