Hi
I just read about this system from finlandhttp://www.kierratysenergia.com/p1.htm
Then, this article says ERV systems in general can return 70- to 80% of the energy to a space.:http://apps1.eere.energy.gov/consume.../mytopic=11900
Has anyone installed these- know the dos and donts? know the ballpark figures on cost ( for the Boston MA area- twice as expensive as things were when I was in upstate NY)?
thanks
Tersh

Energy recovery ventilation is real simple to install. Some just require a couple duct work connections and others the same with some additional fans. They can be a little pricey, but they have a payback of 1-4 years and can be paid for with incentives. There is a company who sells some damn good ones in northern nj BPE. Their site explains a lot about installation. They have reps everywhere too.

Also price will depend on the cfm of fresh air you require.

While I'm a fan of both ERVs, and HRVs.
Why is it you think you need one?
Is your home new, and that tight. Or is it an older home that you improved the tightness of. And a blower door test revealed that you now need one?

Or, did you just hear, that it can save you money?

I agree... residential unless new or really tight gets no real benefit from ERVs. Commerical and industrial are the target for ERVs.
