Well...it sounds like the hor. boring is at least comparable to the pond loops, price-wize (already know both org's contract out the loop portion). I like the boring thing from the standpoint that it's WAY less area torn up...only about a 8 foot cube near the house, and we can "point" them anywhere I want. Plenty of room here.
The "contract" I received as a first bid isn't very specific...I'll ask for more details if I go with them. I want make/model, as I've been looking at on-line reviews of many. I realize it's not perfect, but at least I can see some weak areas for some units...
...and my REC offers $1650 rebate off the top, plus $300 for the HWH. With Fed tax credit (as long as it meets the criteria...a CONTRACT mandate) that's 30% of the total project cost. About $4800 total, so that gets it down to around $9500. Steep, but I spent $2000 on LP alone this year and Electric avgs $160/month.
Make sure that the HP is optimized for your climate and heating system in ex. forced air or floor heating. In example if there are more AC than heating days the HP should be optimized for such operation and vice versa.
We live in a barn (aircraft hanger) converted to a house. 0.7 ac leaky pond.
