Hey KYLE nice info!! just wondering on the front of your control panel are you using the AccuRate thing?? or just the temerature controllers??? Also Im guessing one controller is for your preheat and the other the nozzel heater??
For waste engine oil what temperatures are you using??
I have a type of nozzel heater but its kind of crude. its not controlled very well yet, I was planning to get a PID Temperature Controller to keep the oil at a very controlled temperature. but my problem is that on stright engine oil it over loads the pump and kicks off the motor overload (red button on the pump motor. I think I need to build a preheater. Is it better to preheat the oil or actually heat up the pump itself??
I was thinking the between running the oil in the pump would cool and cause problems?? do you have any problem's with that? or dose the preheater work just fine?? how close is your preheater to the furnace??
Kyle What type of pump are you using to recirculate the oil in your preheater??
