Long story short I bought a house. Avoided it as long as I could, but here we are. We found a cheap house with a six car garage but like many old houses in the northeast it had no central air and oil based hydronic heat.
We went cheap so that we could do stuff like this.
4 ton WaterFurnace 7 Series ground source heat pump with desuperheater
1x 600' borehole with 2x loops (2400 total feet of 1.25" pipe)
Navien 240 Combi boiler for domestic hot water in excess of what the desuperheater can do + backup heat in case of loop failure or inadequacy
Water softener (not pictured) to protect all the shiny new toys
Remove all baseboards, old water heater, boiler, oil tank + oil, etc

Still not 100% done but it's mostly in and functioning. So far on the worst 80+ degree days I've seen (hey it's late September/early October usage, what do you expect?) my cooling costs were sub $1 which is fun. Total conservative estimated annual heating, cooling, and domestic hot water costs predicted by Waterfurnace to be $726. This number is conservative because they could only model to 1" pipe vs the 1.25 we used. Many installers use 0.75 so the theory is I have a very generous loop, my installer claims I won't see loop temps below 40°F or so in the dead of winter. Additionally their math is based on electricity costs of $0.16/kwh, mine will be more like $0.131 year round if not less (due to solar offset of peak usage). This of course remains to be seen.
Many more pictures in the link (~100). More to come with videos likely later.
Remaining for this phase of project:
Repair all baseboards/etc where hydronic system came out
Box in return ducting
Get everything paint ready
Knee wall in attic
Remove all posts from basement
Next spring:
Natural gas generator so all this shit will work when the power is out
Replace the garage (likely with another geo system, 70 degree year round garage FTW)
