I'm working on stepping up to a keggle with a propane burner. I must have read 20 threads on burners and I've narrowed it down to either the SP10 or the SQ14. They're at the same price point but there are differences between the two. The SP10 has a higher heat rating but doesn't fit a keg as is (although it's very simple to mod). The SQ14 fits a keg out of the box but, apparently, it does fine with large boils. Well, what is fine? I'd love some real numbers. How long do you plan for your burner to hit mash temps? How long to boil? The SP10 will get to temp faster. Wait a minute, the next posts says it won't be faster because the extra heat is lost in efficiency. How much faster? Is it 10 minutes faster or is it 45?
