Humidity Control in Cold, Humid Climate
We have a 1000 SF vacation home in coastal Maine that is experiencing humidity problems. We have no mechanical ventilation in the house. In the summer, it needs no AC and the windows are kept open. In the winter, we rely on hydronic radiant heat. Humidity is very high year round (about 80%), but a major concern in winter when we see significant condensation on our windows. We are considering installing an ERV unit but would love feedback on the simplest way to add both fresh air and humidity control, mostly in winter.
