You might get nubers pretty close to 5.0 COP with the ground bieng that wet.
Note: the numbers (30eer and 5.0 COP)are for open loop systems.
out with the old oil/heatpump:
In with the new:
the wet trench
found some springs...
that really flow
the new Envision 30EER, 5 COP Model NDV038A111CTL
Beautiful system. Darn thing is actually quieter on second stage that first. Never fired the oil burner, had to remove the underground tank because of insurance and fire box was cracked. Old trane xe900 kept up suprisingly well while in the teens. Old system power: 5200KVA heatpump mode, 8400KVA cooling (90F). New ENTIRE system power (heat): 1st stage 1600KVA, 2nd stage 3100KVA. No cooling numbers yet.

Karst means cave. So, I search for caves.
30/5 is the ground loop ARI rating on part load for the ND038 model. For open loop/part load you get 32 EER and 5.3 COP.
