I have an evaporator but the past couple weeks didn't have much sap so I just used the turkey fryer to boil. Yesterday I read on here that there were some modifications you could make to make an inefficient turkey fryer a little more efficient. I wrapped the base of the fryer in aluminum foil and it seemed to help quite a bit. Is this safe to do? Are the fumes given off by the foil toxic? Anything else quick, easy, and cheap that I could do to improve efficiency of the fryer? Up until last week I had been using it as a preheater for my preheater to cut down on the condensation falling back into my pan...worked great but if there is a way to save time / money I am all for it.
