I've been having a discussion with a few people in trying to size a Geo Heat pump in a cold weather climate. It seems pretty evenly split, so I figured I would pick the brain of the Geo experts of Hvac-Talk.
In a climate with more heating degree days then cooling degree days, does one size a ground source heat pump based on the heating load or the cooling load?
The particular instance that brought this up is that I was doing a print and the load came up as 75k heating and 30k cooling. So with a two-stage heat pump, do I do a 3-ton or a 6-ton unit?
