It should be noted, the described system and calculations are based on a heat exchanger that is separate from the conditioned space. The drawing on that site is in plan view. Each tube in the heat exchanger is surrounded by 6 feet of earth for the heat to exchange with. DirtFlinger's design doesn't appear to conform.
