We have an open fire, which we use occasionally during the winter. I
rather fancy opening up a vent in the floor, near the hearth, in order

in via the doors to the room.

Does anyone have experience of this?

yes.

Is my thinking along the right
lines?

Yes.

And what would I look for, at Screwfix, Wickes, etc?


Well assuming you have a vented underfloor space, one or two 4" drain
pipes, some cement, and a couple of - in my case - 6" drain covers..the
sort of cast iron thingies that you put in drainpipe collectors and the
like.
