HRV vs. ERV vs. Dehumidifier – Unique Situation!
Hi everyone. New member and first-time poser of question. 🙂 Please keep in mind this is FAR from my area of expertise, so talk to me like a dummy; I won’t be offended!
I live in Central-Northeast WI, so our annual temps run from about -40 to 90+
depending on the season. The summers overall I’d say are mild, while the
winters are colder than I’d like. 🙂
I run a home-based business breeding fish and propagating coral and as such,
have a pretty high humidity level (under 90% is pretty rare). I had been
running a dehumidifier in the past but it’s recently died on me so it needs
to be replaced one way or another. It was also costing me $20-30 a month to
run consistently, and even then kept the house maybe a little dryer. It’s a
small 45-pint LG unit, so likely undersized for the chore. I shut it down
over the summer as things were pretty decent temp and humidity-wise, and it
just won’t turn back on now.
I run ~500 gallons worth of heated saltwater, the bulk of that in the
basement (I do have a 65-gal. display in the living room). My issue is that I get
severe sweating on the windows throughout the house, and it’s starting to
affect the wood trim. The corner closets also tend to be somewhat cold and
develop a musty smell. The house was built in 2005, so my assumption is it’s
With my situation (and trying to be somewhat energy-conscious), would an HRV
help alleviate my issues? From the reading I’ve been doing I don’t think an
ERV would solve my problems, as I can’t ever envision a time when I’d need to
add any humidity back to the incoming air. Or would it make more sense for me
to look into a whole-house dehumidifier?
Thanks in advance, I appreciate your thoughts!
