It is 3 holes dug 250 deep. Loops set right close to 250 may be 248 or 249. But lets round it 250 still 3 ton thats for the whole house well pump house and the shop. (never had money for unit or ductwork yet) And we sized it for the additions i will be doin also
Bein their just sittin taped waitin to be hooked up. I will just use 1 hole at the 250ft. Thats 1 ton. I understand that a ton will do 600-700sq ft But That should be plenty to heat and cool the 450sq ft . 8ft celins. Unless you think thats overkill on the depth. I do know how to dig em my self by hand around 40 to 60ft.
Horzontal i will run 10ft lenght to that closest hole still use the 3/4. so all togather 530ft of 3/4 pipe
