How long does it take to bring the water to a boil?

So I just bought my burner from bass pro with a 7.5gal aluminum pot with a 10lb regulator. Do you guys put it on high to bring it to a boil or just medium? Seems like high would burn through a propane tank rather quickly. How long does it typically take you to bring 5ish gallons to a boil?

don't know what reg,. i have but it takes me about 45 min. to 1 hour to bring 6 gal to a boil. I get four extract brews out of a tank. that includes heating water for steeping grains.

OK, do you leave yours on high most of the time?

I turn mine up to high until it boils then turn it down to maintain a rolling boil.

Same here. I get about 5 batches out of a tank.

Remember though, that if you start all-grain your wort is already about 160* when it goes into the kettle and that's a lot closer to boil then starting from cold. Some people even start bringing the first running to boil while sparging.

I start heating the runoff as soon as I begin the sparge, but I don't actually let it begin boiling until the sparge is finished. IMO, running a burner full tilt will bring the wort to a boil faster, but at the expense of using a lot more propane. It's not a linear relationship and the law of diminishing returns applies. This is one of those things where you must choose between speed and economy and as usual, a compromise of some sort works best in most cases.
