I've tried to do my reading but I'm still confused. Considering a 15 gallon milk can boiler from brewhaus. Would love to go electric. Brewhaus has a cartridge heater (linked below) that I'm considering. On their page they say this 1500 W cartridge is sufficient for up to 15 gallons. But from my reading on here people seem to think that volume requires 5000 W. I can't do 220 V where I still so I couldn't make that happen. Would I be way underpowered with the 1500, or is there something about this specific heater that is more efficient and would do the trick? Could I put two in with just a controller on one of them? Thanks, guys.
