that the only suitable products I've found using google are from US

[For anyone who doesn't know what I'm on about, a whole house fan is a
fairly powerful fan that vents hot air from the house into the attic

idea is that you run it when the house is too hot, and the outside
temperature is significantly cooler - typically to cool things down
at night
after a very hot day.]

Pyriform, did you ever get a useful reply to this?Â* I know what you
mean, having lived in the US we had one of these whole house fans in
our house and it was fantastic, meant we did not need to have air
conditioning installed.Â* With hotter summer days on the increase here
in the U.K., Im interested to get one put in the house here.Â* Our
loft is already ventilated, but I cant find the right kind of fan.
Thanks.

Of course the issue is in the statement that: "and draws cool air in
through open windows etc."

Only if your house has extreme solar gain and no roof insulation is it
going to be warmer inside than out


In hot summer here with 30C outside it is rare to see the inside go
aboven15. At night I open the windows., By day I close the windows and
draw the curtains


Nonsense. Virtually all houses built since the 1960's will have ended up
with internal temperatures well above 20C after a couple of days of 30C+
outside. Mine was up to 26C in Sussex, and that's with all south-facing
windows shut and curtains drawn.
