Discussion Overview

The discussion revolves around optimizing the heating of a swimming pool using a solar heating system. Participants are comparing different flow rates and temperatures of water to determine which configuration will heat the pool water more efficiently. The context includes practical considerations related to the installation and performance of the system.

Discussion Character

  • Technical explanation
  • Debate/contested

Main Points Raised

  • One participant describes their solar heating system setup, including pool size, current water temperature, and available flow rates at different temperatures.
  • Another participant requests additional details about the installation, such as the distance from the filter to the solar panels and the type of insulation on the piping.
  • A different participant asserts that a higher flow rate would lead to more heat transfer and less heat loss to the atmosphere.

Areas of Agreement / Disagreement

Participants have not reached a consensus on which flow rate will heat the pool water to the desired temperature faster. There are competing views regarding the efficiency of different flow rates.

Contextual Notes

Participants have not provided specific calculations or assumptions regarding heat transfer rates, which may affect the conclusions drawn from the discussion.

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.
