Does anyone have experience of this? Is my thinking along the right
lines? And what would I look for, at Screwfix, Wickes, etc?



I don't know whether you can retro-fit them - maybe you can if you have
suspended wooden floors, but it would be a bit more difficult with solid
floors.

My in-laws' bungalow (built in about 1960) had solid floors with under-floor
ventillation for the open fire built in. ISTR that there was an airbrick in
an outside wall, with a metal duct below the screed - terminating under the
fireplace. I think the relevant bits were made by Baxi - but I doubt whether
they make them now!

With suspended floors, and airbricks in the outside walls, is it
necessary to use ducting? I would have thought that some sort of
sliding grid to open and close a hole in the floor near the fireplace,
would be sufficient.
