I have a very old house (yes, it's leaky but I'm working on resolving that) that sits on 3/4 of an acre. The setpic sits right near the house and the leech field is just in front of the house and to the side. I have a long skinny yard with the house pretty close to the road, leaving my back yard almost entirely empty. I'd say I have anywhere from 1/3-1/2 of an acre I could dig up for a horizontal loop system. My HVAC father-in-law estimates my house to require a 4 ton conventional heating system (I have an ancient oil burner forced air system currently with no AC). Do you think I have enough room to install enough piping for a horizontal geothermal system in MD?
I'm also trying to figure out if I can do a return well injection open loop system too, but if that doesn't work out, I'd prefer to a horizontal system rather than vertical for the cost factor if possible. I can dig trenches my self and let someone else do the install
