Yes indeed. Strongly considering a 20 or 30 plate fphe...

I've read several articles that show cleaner burns and more power output even from pump diesel when preheated. The claims are the closer to ign. temperature, the better.

I'm not certain that the heat exchanger is required... However it certainly won't hurt.

On a side note... We have approximately $350 in our whole setup. Maybe 400... We've been able to nickle and dime it and score some great deals on parts, etc..

Would like to go with a motor driven centrifuge at some point but this works so far.
