Hello there, advice needed please!
I have a wood burner temporarily installed in my house, which I am currently renovating. I was originally intending to remove the chimney stack and breast but have decided against this due to complexity and hassle. So I would now like to install my wood burner correctly.
At present a lot of the heat from this 11kw burner must be disappearing up the chimney. There is just a thin galvanised sheet separating the inside from what is effectively an outside space above it. The burner generates a lot of heat but never successfully warms the room in the winter despite good levels of insulation in the ceiling. The sheet of steel can get almost too hot to touch.
So I need to insulate and seal it off somehow, whilst still leaving provision for the flue to be cleaned.
How should I go about it? Thanks in advance!
