I just completed a 10-gallon all-grain batch. I have a turkey fryer burner purchased at costco a few years back. It looks like a banjo burner. It took 1.5 hours to get to a mediocre boil. Based on my recipe I needed to boil off about 1.5 gallons during the boil which took 90 minutes. All told I lost at least 1 hour to waiting for my beer boil. Not to mention my angry foot-tapping wife who I told I would be done at 6pm and I rolled in the house at 8:30. The extra hours caused me to drink more beer which caused me to make sarcastic comments to her questionings like "what's taking so long"? While asserting I don't know what I am doing and I should complete one of the 97 household projects she has dreamed up watching HGTV instead of making stupid beer (her words). I may block that channel with parental controls until I can renovate a whole house in a 30 minute episode like they do. Too save my marriage: Which burner is best? I don't care too much about how much propane it burns. Please save my marriage.
