Maximizing Pool Heating: Comparing Flow Rates for Efficient Heat Transfer

[HullyBear]

I recently installed a water solar heating system for my pool. The pool is 16,000 gallons and the current temperature is 54 degrees. I can get water through the system at 65 degrees at 10 gallons per minute, or slow it down and produce 2 gallons per minute at 80 degrees. Assuming no evaporation and an air temp of 65 degress, which flow will heat the water to 65 degrees faster?

Welcome to the PF.

Can you post a picture of your installation? How far is the solar heater from the pool? What kind of insulation do you have on the piping?

It's about 24 feet from the filter to the solar panels. The piping is drain pipe.

Higher flow rate results in more heat transfer/less loss to the atmosphere.
