I like the idea but have not had time to look at the engineering. We have worked with geothermal (ground source) heating and cooling for many years. Always using the free supplemental hot water as a byproduct of heating and cooling. Many contractors upsold the full time geo water heater but the cost payback wasn't good. My opinion is that this would be a good suppliment to a conventional water heating system, whatever that system is. Worth further investigation!
