About this chimney draught excluders
An open chimney is an unintended extractor fan. Warm air from the room rises up the flue and is replaced by cold air falling back down, and the whole process runs all day and all night in winter. A chimney draught excluder fills the throat of the flue so that this flow stops.
The Chimney Sheep is a pad of felted wool, which is the reason it works for a chimney that you are not using. Wool is breathable, so it blocks the draught but does not trap damp air behind it. It is sized in inches, and this one is for openings around 9 x 16 inches, so measure the opening from front to back and side to side before you buy.
It fits by hand: you push it into place and it holds by its shape, and it lifts out in seconds when you want the fire again. A reminder tag hangs down into the room as a prompt, because the one rule is that it must come out before you light a fire.

The complete guide
A chimney that is sealed solid can build up condensation. That can stain walls and cause damp.
Wool felt lets moisture pass, so the flue can still vent a little while the draught is blocked.
Have the chimney swept before you use it again, and check the pad for soot and dust.
