ERV/HRV Outlet to Inside of Home for Positive Pressure Then Exhaust Through Bathroom/Laundry Fans?
Hi all, longtime reader, new user here.
I’m living in a home I built recently that is super tight and has bad air quality as a result. I need a fresh air solution.
I have two problems I’m looking to solve:
#1) I have a concrete floor radiant system with all my manifolds in the laundry room where I also ran too many loops (probably didn’t need any) and that room gets way to hot, like 80 degrees when the radiant runs in the winter.
I need to figure out a way to get the hot air out of that room and mixed into the rest of the house.
#2) I need a fresh air system
So I was thinking… What if… I installed an HRV/ERV in the laundry room with the inlet coming from outside but the outlet venting into the room? My thinking is that this would create positive air pressure in the laundry room which would then expand out into the house and out through the existing bathroom and laundry room vent fans.
This would also move hot air out of the laundry room and into the rest of the house.
Is this a crazy idea? What could go wrong?
Thanks,
Dan

Is there any way you can reconfigure the manifold connections so you isolate the laundry loop, with a thermostat for that room only?
Do I understand your post to mean there would be no venting run to the baths etc to temper the laundry?
For a decent balance between fresh air and heat transfer…..beats me.
We’ve had radiant in floor for 35 years and our open floor plan seems to have moved the air with one ceiling fan in the great room/dining/and open kitchen area with an open stair/large opening in the 2nd floor master br.
However, the first fl. floors come on around 5 a.m., while the evening firing of a TulaKivi soapstone heater does most of the everyday heating. We’re both retired now so a morning burn is commonplace and the first floor heat is hardly on throughout the day
All this and probably not really addressing your problem…..
Sorry.
