changing from open to closed loop on 3ton unit. got price of $12,000 plus taxes for 3 loops 500ft . this includes flow center and hookup. i will have to do trenching and backfill myself and electrical. I live in eastern canada. fair price? thanks in advance.
Is that 3 bores of 500' depth or 3 bores at 250' depth (500' of tube per 250' bore)? Bores cost ~10 per foot here in FL.
Expensive I'm from western Canada, which means 98% of the US is closer to you than me, but that seems expensive. If you are truly doing your own trenching and they are just putting in pipe. To switch over.. -size ground loop - size circulating pump - dig trenches - install piping - build header - pressure test - add antifreeze, purge, pressurize - day of interior plumbing - backfill to grade Should get all of that for the $ you mentioned.
