After a couple months of planning, I'm slightly closer to having my geo installed The main problem is that I don't believe the equipment exists for what I would ideally like installed. For background, I have a ~2700 sq ft stone farmhouse in SE PA, heat loss calculated ~76k, propane powered hydronic baseboard heating for 75% of the house, and 2 propane powered heat pumps in the attic. I've received 2 quotes so far but only 1 of them was comfortable with a hydronic setup. His proposal included: 6 ton bosch water to water 2 air handlers in the attic 1 air handler in basement with new ductwork 1 ductless mini split (this is for a room where extra ducting isn't easily done and I like the mini split for this area) 1 50 gallon hybrid water heater I have a few questions/concerns about this setup. Obviously I'm not excited about using a lower temperature water in the baseboard system but it seems my options are limited with high temp models that offer heating and cooling. The WF only comes in a 7 ton model and I think I'm already oversized at 6 tons. Would it make sense at all to do a 3 ton high temp water to water for the baseboards and a separate 3 ton split for the rest of the house? What kind if cost difference are we talking about? The major benefit of the high temp model is that I believe I could eliminate the need for an extra air handler and ductwork in the basement (this is for the large great room that has a lot of baseboard, so the extra BTUs from the baseboards plus the 2 existing ducts from the attic would come close to meeting the loss of ~21k for that room). Also how would you all approach DHW in my setup? I hear a lot of mixed things about the hybrid hot after heaters.
