no. thats out of most peoples price range here i think. heck we only have a couple geothermals in the county. the fancy homes are spray foamed with an inverter hvac system here. at some point cost of investment vs rate of return comes into play i guess.have you ever done anything with passive heat and air exchangers? like a whole wall's worth (perhaps several intakes/outakes/vents)?
why not get the honeywell damper? its programmmable and works really well.So spray foam doesn't breathe. There is closed cell and open cell foam. I haven't noticed much difference in the two they both mold. A house has to breathe the tighter you make it the more u need to control fresh air in by an erv or hrv. With out ventilation u can also get sick house syndrome where bacteria can grow in your house and make u sicker.
I would highly not recommend a geo to anyone . A geo is a water to air heat pump. An air to air HP is way more efficient and the initial cost up front can be close to half. Also a geos life expectancy is less than manufacturing claims. Most geos get filled with local untested water and actually needs to be filled by filtered and pure water or the heat exchanger will die.
We're I live fresh air into the house in a controlled way is becoming code. Not an erv yet just a pipe ran directly into the ra of an HVAC system with a manual damper
