Gibby,

I, too, have a geothermal system in my home. For me it is providing heating, cooling, and domestic hot water. The DHW side is being provided by a separate ground-source water to water heat pump, but I am not using it to heat my pool. The more common scenario is to use a desuperheater for DHW and may have been what your initial installer was referring to. The way I understand them, they dump some of the heat that is pumped during the home cooling cycle into a water resevior.

I think you are on the right track in that this is definitely going to take a professional to design/install it for you.

Here are some various contacts I found: (You didn't say what brand of geo equipment you have now, so I'm throwing a bunch your way)
