We have a warm spell coming and so I want to heat my in-ground pool up as quickly as possible. My heat pump for the pool says its maximum efficiency is at a flow rate of 48 gallons/minute. When I set my variable speed pump to deliver 48 GPM the water temperature entering the pool is 92.4°F (33.6°C or 307°K).
Alternatively, I can set my pump to deliver the heated water faster but slightly cooler, i.e. 67 GPM with the water entering the pool at 91.0°C (32.8°C or 306°K). So I’d like to know which setting will heat my pool faster.
The other variables such as pool volume, pool water temperature, air temperature, wind speed, and sun shine are all constants and should not factor into this calculation. And the cost of operating the pump is also not an issue, only how fast I can heat the pool.
So I guess my question amount to this: Which would have more total energy, a vessel containing 48 gallons of water at 92.4F, or a vessel of water containing 67 gallons of water at 91.0F?
