been pondering an indoor brew setup. I have been doing all-grain for three years now, and love it. I have a bango burner that works great for my boils. (I usually do a 90minute boil, and I guess-timate a cost of $4-5 dollars worth of propane per boil).
I had thought of setting up a big pot with built in heating elements (2-3 1500watt 120volt elements) in order to heat mash water, sparge water, etc.
In theory, you could use such a device (not hard to build) to do the whole boil.
At first I dismissed the idea thinking it would be more expensive than propane.
But my math seems to say that it would be cheaper
lets say 4 elements, 1500 watts each (1.5kw). That is 6Kw. For a two hours of heating you would, in theory, use 6kw X 2hour, or 12kw/h. Around here, a KWH is 11 cents, so you are looking at $1.32
Anyone tried this? The question is, of course, how long will it take to get to boiling.
