We live in southern Missouri. Our home is heated with geothermal (closed loop). We are in the process of replacing our main floor geothermal unit with a WaterFurnace series 7 unit. During this process, the possibility of heating our pool with geothermal came up. We have an approximate 16,000 gallon pool. Pool is currently unheated. If we decided to heat the pool, we'd probably extend the swimming season from beginning of May to end of September. Average highs and lows for May and September are 77/53 and 82/57. We'd probably heat the pool to 82 degrees. I've found it difficult to find information online re: heating a pool with geothermal. I would think the 2 best options would be 1) geothermal vs 2) air to water heat pump. If going geothermal route, I'd assume we'd be looking at purchasing another geothermal unit specifically for the pool. Does anyone have experience with this? Thanks in advance for the help.
