Well the biggest burner i can find is 230,000 btu. I'm gonna put a 5500 watt element in there too. Hopefully that should do it. Going by what i read earlier, i really need about 400,000 btu's, so hopefully the element will make up the difference. I read that at 100% efficiency you need approx. 1800 btu's to go from 70*f to a boil per gallon of h2o in an hour. So 4 times that is a more realistic figure.
Thanks
