HRV vs. whole-house dehumidifier — Need help choosing
Hello, I have a 1700 sq ft house located about an hour North of Albany, NY. The house was built in 1998, and I just purchased it last year, it is fairly tight, but nothing exotic. It has 2×6 walls with fiberglass insulation,R-60 in the ceiling, double pane vinyl windows, and vinyl siding. The house has a few year old high efficiency forced air propane furnace and no AC.
Since living in the house we have noticed it seems to be very humid. The mirrors fog up during a shower very quickly, even during the summer months. The basement is damp, in fact soon after moving in we had mold grow on some boxes that we placed in the basement for storage. Since then we have been running a dehumidifier down there most of the year (except winter) and no more mold issues. Finally, during shoulder season and the winter we get condensation on the windows. We tend to keep our house cool (60-65 degrees) during the winter, and it seems like the condensation on the windows is less if the furnace is running more (this tends to make sense as the furnace is drying the air, right?).
Therefore, my question is this. What makes more sense in this application, a HRV or a whole house dehumidifier? I already have full ducting in place due to the furnace and plenty of room in the furnace room in the basement for any required hardware.
I would love to hear the pros/cons associated with both. In the end my goal is to reduce condensation on windows, reduce any mold issues , all while trying to accomplish it efficiently.
