Have just made an offer on a 70s property which had had ducted hot air
heating. This has been replaced at some time with a gas boiler and
conventional radiators. The original vents for the hot air have been
left in place but now seem to serve no useful purpose. Can they be
blocked off? -any suggestions of the best way to do this? It occurred to
me to remove the metal grilles, fix a piece of plasterboard in the holes
and skim over to give a smooth finish; is this a reasonable idea?

This is exactly what we did in my M-I-L's bungalow

That's what I did the other week. Seems to work. One problem that I did
have is that there was no wall below the vent, just the metal vent
covered with some metal gauze. But stuck the plasterboard on with
no-more-nail type adhesive and it seems OK so far.

For the floor vent in the kitchen I filled with rubble. Sealed with some
cement and tiled over.

That was a couple of years ago and there have been no problems since.

No, fix them up to a central vac. unit in the garage and use them to
suck away the dust...

remove gauze, stuff with newspapers, bash gauze back about 3/4" below
desired finished level and fill with bonding plaseter.

skim and sand back flush?

Wow. Great potential for easy install of network, telephone, TV and
speakers, and plumbed in Beer Taps ;-)

It must have been some dumb bathroom changer who did that who knew nothing
of heating systems. How sad.

This is exactly what we did in my M-I-L's bungalow

Now I've moved in I find that the double glazing does not have any
ventilation slots. If I block the redundant hot air vents the rooms
would not have any ventilation at all if the windows are closed. One
room has a gas fire connected to the chimney so presumably that room
needs some air inlet when the gas fire is used; how best to do this?
Do the other rooms need ventilation?

Best way is to replace gas heater with a balanced flue one. Not as
good: make hole in wall, sleeve the cavity, fit grille.
