The EER on their ground source heat pump is abysmal.
For a 4 ton pump, they have 17.5 EER, 3.9 COP
For the O(same price) for the unit, the waterfurnace 7 series is 41.0 EER, 5.3 COP.
(Both can provide all hot water, etc).
The waterfurnace also carries a 10 year warranty instead of 5 year labor/10 year parts.
Can't speak to the drilling rig, which also seems interesting.
