Creating Conditioned Space for HRV
When I bought my house 3 yrs ago the existing air exchanger was in the attic. It was not functional, and the ductwork was a mess. I removed the ductwork and stuffed the remaining holes with plastic bags and insulation (temporary measure!), planning to install an HRV properly in the future.
Well, the future is now approaching and I’m looking at my options. I’ve looked through just about every applicable HRV/ERV/HVAC on here, so I am well aware that the HRV can’t go in unconditioned space, and ideally the ducts wouldn’t be either.
The problem is, there is nowhere else to reasonably put it. The little bit of basement I have would require putting the outside intake/exhaust right beside the neighbors driveway or in an area that gets covered in snow.
So having said that, what can I do? I’m thinking maybe build a small “room” in the attic, properly air sealed and insulated from the rest of the attic. And then run the ducts in the attic, buried under blow in cellulose.
Central Newfoundland, zone 6/7.
Electric heat, no existing ductwork.
2 storeys + finished basement.
The basement has a small utility/laundry room, the rest of the basement is a separate apartment.
