Hi folks
I am investigating getting a Dry Living system installed into our old, damp, 60s brick house. It is like an HRV, but the Plus System only takes air from the outside, runs a dehumidifier over it, and then uses a heat exchanger to warm it up before bringing the air into the house. They're a bit more expensive than a Smartvent system at $7,600 installed vs. $4,600 for a Smartvent Evolve 2 + outdoor air unit. However the Smartvent doesn't have a heat exchanger, and only uses outdoor air sometimes.
Does anyone have any experience with this system, or experience in the area to know whether this sounds like a good system or not? I like the idea of not bringing in air from the roof cavity, but maybe after the filters it doesn't really matter? Also, we have someone in the house who is allergic to dust mites, does the roof air make this worse?
