    What GPM would I need for a 4 ton system pumping an open or closed loop system at 50 degree year round water temp. (House is 9000 sq ft).

    I had to move my irrigation river line anyway so had a 150ft trench dug wide enough for plenty of PVC pipe, from the river. So, whilst the trench is dug, in case in future I do go this GEO thermal route (either open or closed loop), I might as well lay as much as I'd ever need before I fill the trench back.

    I was going to lay 2x2" pipe "just because" but if enough water can flow through a 1" pipe, I'll just lay that. Worst case, the pipe sits for years doing nothing :) - In future, of course, I could go totally GEO so that's about 12 Ton's for my house.

    3gpm per ton for closed loop and as little as 1.5 gpm per ton for open loop depending on the tuneing of your unit after install.
