I’m in South Carolina, with a WF7 & 4 ~150ft bores. I’ve read Doc Jensen and others say that ASHP is cheaper and a better option because of ground temps vs air temps while attempting to heat a pool. I’m assuming this is because many of the Geo guys on here are up north with Much lower ground temps. My question: my Loop temps currently sit at 72 (never got above 75 last summer even in the south) and in the winter never got below 67 (my WF7 only ran 6 times the whole winter. Spray foam and having to run a separate dehumidifier cured having to run the Geo). In the shoulder seasons where I would want to heat my pool, I use absolutely no geo, and in any case, I assume it would help the loop field by taking heat from the ground just before and after I am adding heat from the geo due to cooling load. Would it make sense in my case to heat the pool using my existing loop field and an add on W-W unit or just go with the existing consensus and get an AquaCal ASHP for my pool? I also consider Upfront cost VS long term savings with either option. A Hayward Heat Pump (I would upgrade to an Aquacal) was quoted at $4500 installed, approximately how much would a W-W system cost?
