A couple of years back I posted a question .. didn't get very far,
thought I'd try again.

I have a modern highly insulated 2 storey house, and this time of year
the upstairs get very hot .... and with high values of insulation it
does not cool quickly ... bedrooms are very hot.

In the US they have a very good solution "Whole-House fans" when temp
drops outside in the evening you switch these on, being fitted on
upstairs ceiling it vents the warmest air in the house into attic space,
this air then being replaced by air form downstairs windows being put in
vent position.
Explanation video & installation video on this page:

I have been unable to find a manufacturer in Europe .... anybody out
there know of one ?
Getting fans & remote control would not be difficult, but having
'actuating motors that open the insulated doors would appear a lot more
problematic.

Welcome comments from anyone who may have looked into this.

I could buy the US items and run off a 220 - 110V converter .. but it
would not be cheap to ship over plus 20% VAT on import.


Not looking in the right place ?

Unfortunately no ..... I already have a full whole house heat recovery
system ... which is what this unit is part of.
Works very well, includes 4 stage filtration including electrostatic ..
other than when hot ... then it does not bring in enough cool air even
on high speed.

I have this system ...

The original design allowed for addition of a 'cooling' module to cool
incoming air (not air-con just allowing several degree temp drop)

The company never produced the module though.
