a friend has told me that a wood/coal burner sucks air into it and up the chimney, air comes under doors, through windows and floor boards, he says the answer is to have a separate air supply, perhaps coming from an airbrick in the wall through a plastic drain pipe under the floorboards to very near the air inlet of the burner, with a closable grill for when the burner's not burning.
Of course , its obvious once he said it.
So what kind of an openable grill?
or could i feed an airpipe directly into the burner?
the burner in this room is a Rayburn number one, with an air inlet at the front under it...
