Interesting, what are you outdoor humidity levels like? Seems like a good problem to have vs high humidity.That is what I understood as well ... but, I have an HRV and the company I have always used, now recommends an ERV for my location, which is in a cold climate. I can see why. I struggle to keep enough humidity in the house in the winter using the HRV. My solid wood furniture does not appreciate the low humidity levels, followed by high humidity summers.
I am planning to swap my HRV for an ERV and will move the HRV into my fishroom. Overkill I know, but I will already have it, so I might as well use it. This will allow me to separately ventilate the fishroom.
Here in FL, I have high indoor humidity but even higher outdoor so sadly will need a dehumidifier and ERV
