wingedfish, no problem a $1000 for labour and probably would have agreed to $2500 a unit with installation, to cover markup on the unit and other materials. Just couldn't do $4000.

bkelly, again the insulation shouldn't be wet. No expert but I'd replace.

Not only does it remove the humidity, it actually does recover the heat.

Inserted a temp probe in the ducts a couple of feet from the unit (house side) exhaust 22°, fresh air 13° with the outside air measuring -9°C.

There are multiple ways to do HRVs
A stand alone system with supplys in the bedrooms and living room and exhausts in the kitchens bathrooms is best but alot of labour $$$ but you can also just tie it into your supply and return ducts off a forced air system not as good but substainally cheeper

Fully ducted would have been best but since I was installing in a house complete with finished basement still think having a separate stale intake with fresh air tied to furnace a good compromise (middle picture). Think my numbers also show it worked out okay.

Here's a diagram of installs

yes.

how did you do picture 2 if your house is finished?
picture 2 is better than picture 3 but very rare to see as you also need the house open to do that. tell u the truth Ive heard of it but never actually seen picture 2 style.

most people do picture 1 or 3.
