GSHP Vs whole-home dehumidifier
I am looking at retrofitting my home with a GSHP (please see the below thread for details):
I am also planning to have an HRV and a whole home dehumidifier (Lennox 65-pint) installed as part of the new setup. My question is:
1. The contractor has quoted a 3-ton system (please see the above thread for details) because a higher 4-ton unit will not run long enough to do dehumidification in Summer. Now what I am wondering about is which is more efficient at dehumidification: a longer running 3-ton Geothermal unit or the Lennox 65-pint whole home dehumidifier?
2. In winter, does the GSHP do any dehumidification at all? I am hoping the HRV will help in reducing the humidity levels so the Lennox dehumidifier doesn’t need to kick in often (I have high humidity inside in winters).
I am planning to have the setup such that the Lennox will stop whenever the Geo starts. I am also planning to have my thermostat at a constant 72 in winter and 79 in summer (as opposed to going down to 69 and 81 respectively at night time).
