Cooling a Hot Pool

[KurtV]

If you're in a hot, humid area like the SE U.S,, there's not much you can do. If you have solar heat, running it at night so that the panels radiate heat into the (slightly) cooler night air will help some. Likewise, some kind of fountain (as Philbo suggested) will produce some evaporative cooling, but with high humidity there'll be very limited benefit.

If you're in an arid climate a fountain will help quite a bit.

1. Run your pump at night only, this will move the water around at the surface allowing it to cool off better than just leaving a still non moving layer exposed.

2. If you are able to tie into your system easily enough near the pump using a couple of bypass valves, get a 100 foot coil of the black relatively stiff 2" hose and redirect your water through that while running the pump over night, this will act like a cheap low grade solar panel and do a heat exchange through the exposed plastic with the cooler surrounding air - you can leave the hose in a coil, so the area you would require for this is approximately 4'x4' near your equipment pad/shed.

When I read this, I wondered about burying the coil if you were doing some construction such as building a shed.

If you have about an hour to build it, this will work:
