hi dasorge. I can't see why that would not work. I use a "Brew belt" with a towel wrapped around the bucket and that works fine. Other people use electric blankets. aquarium heaters, insulated box with a small lightbulb and other methods. They all work. I would test the heat tape out on a bucket of water to make sure it will keep the mash the desired temp. Good luck and have fun.

Ok I'm pissed!!! I got a 6 foot heat tape from the local big box hardware store. I applied the tape to a bucket (one I use for fermenting) and the temp on the bucket NEVER got above 64f. After reading the directions (grandpa always told me if it fails to read the directions!) there is a thermostat on the tape -- its a little plastic box thingy on the tape with a bubble on one side which is suppose to go against the pipe. Anyway, the thermostat is set to engage at 35f and shut off at 55f. That tape is useless for what I need to do. I even wrapped the bucket with a blanket to help keep it warm. Oh, by the way, I have to ferment in the basement so the other half doesn't get mad! I looked on the Brewhaus web site and didn't see the "Brewbelt" anywhere. I know they use to carry it. Any suggestions for heating up fermenting when it's sub-zero outside?
