Last night and today we have very high winds and it is -3 f right now. My woodmaster sits out in the open where the wind hits it directly. My question is, would a rain cap or chimney cap help with slowing the wind that's going down my chimney and allow me to get more of a burn time? If it is just cold no wind I can easily get 12 hrs burn time without even filling it all the way up. I filled it clear full last night before bed and at 7:30 this morning I went out and the water temp was 97 degrees. :censored: Thanks for the help.
