I've scoured these forums but I can't find info on this- could be it's really a dumb question, but I need to ask. Why do you need a process boiler to heat your steam jacketed still instead of using a powerful home gas powered steam boiler like a 221K BTU Crown? Is it too weak, dangerous, or just plain wrong? I'm opening in a very small space with a small 100 gallon still and 100 gallon mash tun. The building has city natural gas and 200amp 3 phase electric service. Initially, because of the gas, I was thinking steam. But I found information about the equipment was hard to find. Then I spoke to someone who said electric was the way to go, and changed my mind. Less hassle with equipment, fire code, etc. Electric is easy but not free. About $4K for the hardware per unit then $0.12per kwh to run it. Hmmm...I started thinking about the steam again and this question of using a home heating steam boiler- Can it work?
