Anyone expericend with HRV or ERV? | Construction and DIY projects | Forums

Been researching HRV's and ERV's for the new place.  Air exchange is a concern with building 'tight', and if we go with the spray foam upstairs it is even more important to be aware of air exchanges.

I know some people advocate for earth tubes.  I don't see us going that way, the cost of material and trenching for us would be a lot more $$ than a HRV that I can install.

Being that we are building with very open floor plan and only 1 Bed Room and 1 Bath we only need a small system.

Most everything I have read says that a HRV is appropriate for the colder Northern Climate.

The HRV units are about $600 to $1,100 (the ones I am looking at least).  They are pretty simple to install in a new build.  Nice.

Thinking this would be money well spent to keep the house 'healthy'

I need to do some research though on building my own set up though.  I think I could build one that is more tailored to my set up and needs (important since we are not building very conventional).  There are some nice 'fans' to move air in and out that are good prices...could be set up with a simple timer that turns it on and off depending on the needs of the house. The duct work and the vents would be the same regardless...and the fans/timer/etc, are much less expensive, even when I add  in a simple filter set up...this makes it cost effective.

Any thoughts or knowledge on this folks???
