There has been alot of talk lately about how the heat lost through an interior chimney is recaptured in the rest of the house. I was outside fetching wood and I looked up at the roof and I was kinda surprised. This is a concrete block chimney that is faced with granite blocks. And the granite blocks are a good 6 inches thick. The whole roof is covered in snow except by the chimney. I have a 6" liner and a blockoff plate, but no fireproof insulation above or around the insert.
I know people have said their block doesn't get anything more than warm. I think that's because the block is pretty good at wicking heat away and not getting hot.
I think there is alot to be gained by adding insulation above and around an insert.
