Thinking about installing an air conditioner heat recovery system to heat my in-ground swimming pool (how much, heaters)

[The Villages Guy]

I just found out about air conditioner heat recovery pool heaters. They use the heat coming off your AC condenser to heat your pool. I live in Florida, so the AC runs during the pool season. My AC unit and pool pump are already right next to each other, so it would be convenient. No installing anything on the roof, it would heat the pool when AC is needed in the house and they claim it reduces your cooling costs, as it is cooling the condenser.

Has anyone here used these?

How much did they charge you?

What brand is good?

Thx. I am excited about this possibility.

I don't have any first-hand experience, but I think most geothermal or ground sourced heat pumps could do this. In principle you could use heat from the pool to heat the house in winter, at the expense of the pool getting cooler. The only question would be your pool water's chemistry, and finding a heat exchanger that's compatible with it. A salt water pool would be the worst, maybe requiring a fresh water loop and a heat exhanger in the pool

I found this option and it has a video link of This Old House installing one. I am very interested in this. They say this technology has been in service in stores for years.

my only experience that is remotely similar is an ERV. Energy recovery ventilator. In a commercial bldg, normally you have supply and return vents. But not in rest rooms. you don't want stinky restroom air being redistributed throughout your building. it's usually just exhausted out. but because it's conditioned air you waste a lot of energy SO... there was a unit about the size of a VolksWagon that had a big disc-looking wheel. it turned slowly and the vented air passed through the wheel. somehow the heat got captured and was sent back through the system. it was around when the new base was built at the Memphis airport around 2000 design phase of the project
