I have a living room which is about 11ft x 6ft and also a plasma fireplace with a flue. In the corner of the room, I have a vent (to outside) which is quite big... 6in but 6in (standard tumble dryer vent).
Currently it is acting as a air conditioner and my living room is too cold.
Do i need this vent? as my fireplase already has a flue be hind.
