I've decided these are a good idea, and I'd like to fit one. The
trouble is that the only suitable products I've found using google
are from US companies, designed for 110V. Does anyone know of a UK
supplier for this sort of thing?

[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
space (and thence outside), and draws cool air in through open
windows etc. The 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.]

As heat rises just leave the loft hatch open and the house will vent
naturally, it's green to boot.

I know about natural convection, thanks.

And I want to install a fan, since forced cooling will be much more
effective, on those (relatively few) occasions when I need it.
