One more quick propane question regarding the dickinson stoves.
1 gallon of Propane ~= 4.23 lbs ~= 91690 Btus
1 lbs of Propane ~=21,676 Btus
20 lb tank of propane holds approx 4.73 gallons of propane (433,694 BTUs)

Then for the dickinson 9000model if you run it at 5500btu/hr you should only get 78.9 hours of usage (433,694/5500 ~= 78.9) yet the dickinson website claims 140hrs at this rate.

For the high setting of 7500btu they claim 100hrs though 433,694/7500 yields 57.8hrs by my math.

What gives? Surely a pound of propane can't produce more than 22000 btu. So does the stove not run as long as they say, does it not put out quite as many btu as they claim, or am I missing something else? I'm hoping that I'm missing something as I'm actually sold on the idea of a dickenson 9000 for a forepeak heater on my boat if their numbers are indeed correct.

I have a sauna on my boat, therefore I win.
