I'm told that propane burns hotter than butane, though butane releases more heat, and thus the two are considered about equal in heating ability; it therefore seems all right to replace the mixture with the single gas.

What I don't know is the pressure in the large tank as opposed to the smaller one. If the propane tank pressure is higher than what the little tank is designed to take, it might be dangerous to refill the little tank.

You've probably already considered this, but I thought I'd mention it; I may just learn something new.
