We have a two story house (in Nelson), with an open stairwell  between the two levels.  We were told that a ventilation system that circulated between the two levels would be very-difficult (expensive) to retrofit in our house. 

 

They suggested a ceiling fan in the stairwell to push warn air down in winter or reversed pull cool air up in summer.

 

Years ago, one of the ventilation companies was selling individual room ventilation units that incorporated heat recovery.  They were installed in the wall close to ceiling height.  I was looking at them for a house I moved out of in 2007.

 

 

Sounds like our house. 

 

I've got an appointment with SmartVent, they seem to cover a lot of the options we are considering, hopefully they aren't pushy and revolting like HRV

 

 

We used Smartvent in our previous house in Nelson.  We were very happy with the service, product and performance.

We have a Smartvent here too.  Balanced pressure Synergy 250S model with core bypass.  Single storey house but quite long.  I did it as a self install. 

 

We've been happy with it for the last 5+ years and am now considering the ducted heatpump upgrade for it.

Sorry to resurrect the thread, but how did it go?  From everyone here recommending SmartVent I've also just requested a consultation.

Apparently Penjerex window film works nearly as well as double glazing

So I tried to find out who sells the film that goes on windows which acts like double glazing but not really having much luck. 

 

I am surprised that it's not possible to have a heat pump in a room and somehow get the cooling/heating effect of that into a room that shares a common wall. 

 

I'd have thought it would be a case of an extractor fan, some conduit and a fan into the second room?

And a return duct.
