Title: What temp should oil be preheated to?
Post by: Russ on January 01, 2009, 10:44:50 am

From what I have heard:
WMO: 180 - 250
WVO: 275 - 325

What is everyone else preheating to?

well on the wvo.. I donno, but on the wmo I do know that if you go much over 180 f you will start to clump the carbons out of the oil, eventually clogging your nossel

Looking at "factory made" wmo units, they run at 160 degrees and talking to Mike of "Mike -Donna" he recomended arround 170 and no more than 180 degrees or the oil will start to carbon up and start plugging nozzels.

I've been running mine around 200, maybe I will turn it down a bit.  Dont want plugged nozzles!

 I heat all my units at 165F is a realy good temp.

Well, I found out why I was getting the woof, woof, woofing when my burner was running.  The temp was too low.   I had the PID set to 200 degrees and sometimes it will overshoot the temp and I noticed that when it got around 210 or 215 things would even out.  I upped the temp to 220 now and it is burning smooth again!  I'm not saying that the oil is actually that temp, but that is what the thermocouple is sensing.  I never gave it any thought because we had been talking cooler temps earlier.  I guess each system varies a little, so it is a good idea to experiment a little.

Later....

140 degrees is about what you want for optium burn w/o the carbon build up, if using synthetecs must heat all the way to the nozzle.
