Hi all,

We have recently moved into a victorian property with open fires. When we have the fire lit in the lounge we get quite a draught coming from around the lounge door frame. This draught brings cold air from the hall across the lounge to the fire place. As the house has a underfloor area complete with air bricks, would fitting a floor vent next to the fire place solve the draught issue?? Also, would bringing in cold air from outside through the air bricks to the underfloor area cause us more heating issues?

I think that the air being sucked into the lounge is coming from both the other chimney in another room and from the cellar which is quite cold. The cellar is obviously linked to the underfloor space but its blocked off but not sealed.

Any advice?

Cheers

A couple of years ago we had a new fireplace installed (room is last extension to the house, added about 1910). Fitted a floor vent in the alcove next to the chimney breast, hidden by the TV. Only notice the draught when playing with the aerial cables that come through the wall above it.

My parent's fire had a metal vent about 10x2" in the hearth which could be closed when there was no fire. It seemed to work very well; no draughts that I can recall.

Open fires need a lot of air to work correctly - otherwise the fumes come into the room and aren't good for you!

If you have underfloor space you can channel air to the fire from an outside wall - one house we lived in had a pipe system with a simple lever to close when the fire wasn't lit.
If I lit the fire with out opening the vent it struggled to get going - open the vent and the fire roared away in minutes.

As I said you need air but you can make sure it's coming from where you want it to rather than causing drafts under doors etc.

Thanks Steve,

Our fire is certainly getting enough air as it roars away. We just want to stop it pulling cold air across our lounge as its becomes very draughty. I am thinking that as long as we create a vent equal to or as large as the gaps around the door then we should be able to kill these draughts. I like the idea of a adjustable vent so we can close it off when the fire is not in use.

Cheers
