I have a geothermal heating system in my home. I would like to find a way to utilize the output of my heat pump to send the heat through a heat exchanger that will put the heat into the pool before sending it out to the rest of my ground loop. I have seen a number of things like plate heat exchangers and such, but I was wondering if anyone has any practical experience with such a thing. It seems like an easy concept. My heat pump cools the house in the summer by removing heat from the air. So why not feed that heat into my pool to maintain the temp I like and then send the rest of the heat into the ground as usual and keep from having to use a ton of propane. Any thoughts?
