Whole House Fan

[Rick Hughes]

were you blowing air into opening with a fan ? .... that is supposed to be the big improvement

[Grimly Curmudgeon]

No, leaving it to passively vent. No way to mount a fan conveniently anyway.

Does that air from the basement include Radon gas, which is radioactive and bad to breathe?

[Davey]

Since in this case the basement was in fact a half basement, with a door to the outside world, and was effectively part of the house, and the house was not very old, no.

[Tim Downie]

I didn't think that age of the house was a factor. More to do with radon leakage from the ground beneath which is dependent on where you live.

yes.

Radon is heavy and in unventilated spaces built over (typically) granite with no tanking., will collect in cellars and houses.

Simply ventilating floors reduces concentrations massively.

That's odd, my somewhat similar setups have worked very nicely for ages. I have seen some people fail to understand them though, and run the fan at the wrong times with a poor result.

That'll be because you're responding to harry, who has taken up the the mantle of comprehensive wrongness from Duhg.
