Q: How long will a cylinder propane last period?

Propane weighs about 4.2 pounds per gallon. So a 20#cylinder holds 4 1/2 to 4 3/4 gallons of propane. A gallon of propane stores about 92,000 BTUH’s, (+/-). So in rough figures, if the head consumes 45,000 BTUH, you can get 2 hours per gallon, (8 hours per tank) or a bit more, when using on high. It’s just math: Med is 30,000, so 3 hours per gallon, low is 15,000, so six. Mine seems to run longer times than that, so I assume it’s burning at a somewhat lower rate than listed.

Q: will it heat a 3 stall garage?

It will heat my 30' x 25' garage with 12' ceilings no problem, I have insulated walls but nothing for the ceiling. I have to turn it down after awhile, which the lowest setting is sometimes still too high, and I have to turn down the propane at the cylinder haha. I use it to keep the temperature at around 50 degrees when it is 20 or colder outside. But, though a bit costly, it really is a great heater...just keep it several feet away from plastic items.. I know from experience.

Q: how much propane does this use when on high

Not sure how much per minute or hour but on high for a 20lb tank it last about 8 hours

Q: How many hours of heat on low/high from a full 20lb tank?

This unit burns a lot of propane. On high, I get about 10 hours from a 7 gallon propane tank. Doing the math this burns about 1.413 hours per pound of propane. In general, all 30,000 BTU heaters will use the same amount of propane as any other 30,000 BTU heater. The number of BTU's produced from burning propane will be the same regardless of brand.
