i am planning my own electric brewery. my question refers to power. the place i plan on brewing already has a 30A circuit installed, i plan on using that. i really don't want to go higher, the house is old, it has 150A service, and i find all sorts of scary wiring errors whenever i dig into something.
i am planning a 5 gallon system, but really only because of the 30A number, and i honestly would rather go 10 gallon.
so here's the question for all of yous guys who have built an electric brewery:
how long does it take to boil? my calcs tell me with 6000W max (25A at 240V) it will take 11:15 (about 1 min longer for a 5500W element) to bring my 6 gallons of wort to boil ( dT 80F - i live at 7000' boiling is ~200F and my wort comes out of my m/l tun at ~120-130).
that said, 100% of my power does not go to heating the wort, or does it? what sort of heating efficiency should i expect?
i plan on insulating my hlt, m/lt and kettle, but the tops will be open, so i expect some heavy losses there. any thought?
i guess the next question has to do with the specific heat of wort, but i think i need to assume that its greater than 1.00, i assume it depends somewhat on the o.g. but does anyone know of a formula or rule of thumb?
