How long does a Big Buddy Propane Heater last?

Billy,

It is very strange that the burn time is different. The burner blocks are exactly the same for the Buddy and the Big Buddy. The Buddy has one the Big Buddy has two. On low the second burner block is off.

Francesca Knowles: does the above affect the formula you posted?..:h

.

The formula is strictly related to number of BTU's per pound of propane. Calculations would be made based on size/number of burners going.

If as Jauguston posted both Buddies have the same size (rated) burner, propane consumption should be the same if only burning one burner....unless "low" settings are somehow different.

I'm not exactly sure which models we're discussing here- it looks like there are (at least) two single-burner Buddy heaters.

This one has a 4,000 BTU burner and I think it's just off/on.
and
this one has what looks like one burner, and adjusts from 4,000 to 9,000 BTUS.

And the Big Buddy with two burners, has three "heat settings", the lowest being 4,000- supposedly just like the little single burner.
BUT:
Top "speed" is 18,000 BTUs... I don't see how that would be possible if it just had two 4,000 BTU burners identical to the little Buddy.
