Loved it. I had a closed loop with desuperheater. Closed loop are less efficient but cost less to operate since you’re cycling the coolant instead of lifting/pumping water.

I kept the house at 68° in the winter (felt warm in the house, but it’s true the air will blow out of the registers warmer than a regular heat pump but not hot) and never used the auxiliary coil down to negative degrees in the winter and 68° in the summer with temps well over 100° outside.

Closed loop will also get progressively less efficient as the season progresses and you warm or cool the wells.

All that being said, my electric in the summer was usually $100, $110, $125, and heat was $125, $150, $165 for the peak months. Baseline was about $80. Cooling is where it really dominates.

It is very dry heat, so get a humidifier or your shock yourself with static electricity all the time.
