WebAug 4, 2015 · I takes a constant amount of heat to boil off (vaporize) 1 gal (the latent heat of vaporization), no matter how much liquid is in the BK. There will be a small difference in the amount of heat lost from the sides of the BK at different fill levels, but that is a minor effect. So, for a constant heat input, the boil off rate is almost constant.
