What time should I run my Heat Pump in Florida

I am looking to maintain my pool at around 85 degrees in Orlando during these colder March nights.  I was thinking the best approach would be to run my pool at night and use the heat pump to maintain the 85 degrees during when the night is more likely to chill the water.  I was curious about what others do in this group.

Heat pumps are more effective, at recovering heat, during the warmer parts of the day. Depending on when the pool will be used, that may not allow enough time for the heat rise demand. If the pool will be used mainly in the late afternoon and evening, having it come on in the morning would be ideal.

If swimming is taking place in the morning, running the heat pump through the night would be sufficient. Depending on the time clock or control system, a four hour on four hour off schedule may work best to ensure that the heat demand is recovered in time for swimming. Hope that helps!

Which way do you think would be better? If the water is at 85 degrees when the sun goes down would it more efficient to try to keep the water at this temperature throughout the night using the heat pump?  Or would it be more efficient to keep the heat pump off and let the temperature go down throughout the night and then try to increase it again in the morning?

The heat pump is going to run more efficiently during the warmer parts of the day. So if you're concerned with the energy efficiency of the heat pump, run it during the day.

My suggestion would be to run the heat pump during the day and add a liquid solar blanket. The liquid solar blanket will help prevent heat loss during the night.
