Query: Precise Control and High Output: Great for Brewing

Would have liked to know the minimum and maximun BTU output so I could have compared it to my stove burners(too wimpy for brewing)before buying. The SP 10 arrived exactly as advertised. The control valve allows very precise flame control. I boiled 2 gallons of water in less than 10 minutes on high and kept a good boil going with the valve open only 1/8 of a turn. Plenty of heat to boil the 5-10 gallons needed for making beer while being able to control the boil rate. If you are a home brewer,this burner will do the job.
