I got some more details about this system from the head of the project, he said that it was a 700 foot coil, not 200 foot like I was told before, they haven't picked out a pump yet so they aren't sure about electrical use either, but specs for this type of ground loop apparently say 8,000,000 BTU per year for heating or about 80 therms worth of natural gas per heating season and that it can take care of 100% of the cooling needs for the house.
This is on a house that is around 1,000 sf with two solar hot water panels for heat and just over 3kw of PV that is designed to make it a net -0- house, rented to low income people and it should make a profit.
