On second look, I have (2) burners... one came with a 10psi regulator, one came with a 5psi regulator... I USED to use the one with the 10psi reg... then I bought another fryer and started using the 5psi reg. without really realizing it. It seemed like the 10psi burner would boil water faster than the 5psi burner, I may do a test with like 2 gal of water starting at the same temp, throttle them both wide open and see how long it takes to boil that volume on each burner.
Basically I am really happy with my setup, it is really efficient and very accurate at holding temps. The only way that I can think of to improve my brew day is to reduce my time to heat water and boil. I will eventually save enough to possibly buy a 200k BTU burner. I love brewing, I hate waiting for water to boil. I will run the test today.
