Okay, so I'm assuming this question has been asked and answered before, but since I'm browsing at dial-up speeds I'll ask it again. I want to use either the Johnson A419 or the Ranco ETC-111000 on my HLT. I'm not partial to either one, they just fall in the affordability and ease of use category.
I'm no electrician, but I believe that I have 240v running to my garage. What kind of heating element will work with the controls above, fit in a keg (mounted horizontally), and can heat 12 gallons of water in a reasonable (an hour or less) amount of time?
