In any case, does BTU directly relate to PSI? Should we be looking for something in between 1 and 10 PSI, or would 1 be enough?
I'm already over my head in this discussion. However I'd venture a somewhat logical guess that the higher pressure regulators produce the highr BTU ratings. I suspect that a low pressure regulator might be the ones with perhaps a minimum PSI of one a very low burner flame and 10 PSI the upper limit of that flame for that burner and that PSI. I'm making these numbers up but when you turn the burner on low perhaps the one PSI would correlate to 5,000 BTU and when you turn it on high to 10 PSI you have maybe 12,000-15,000 BTU. Our current side burners?
If it were a High pressure regulator say maybe 20 PSI then at five PSI you have 5,000 BTU and on high at 20 PSI your running 75,000 BTU? This is just therory on my part. I doubt that they would make a High Pressure LP burner that would utilize the throw away screw on LP bottles?
In all likely hood I'll probably end up with what I had or similar. Or the only other alternative is to purchase an auxillary stand alone unit. The latter is not my first choice. However if push came to shove I would look at using a splitter and running say a turkey fryer burner off my Afterburner tank.
Seems the turkey fryer style burners are in that fifty to seventy five thousand BTU range. More than most any of us would ever need for a side burner I should think?
