Pool Heat

[Djunda0]

Hello, I have a question about guest staying and they want to pay for pool heat. 

should I leave the pool heat running all day and night when guest book or is it better for my cost to turn off at night. 

I am not sure if it will run more at night or more in the morning to reheat. 

Thank you.

@Djunda0 The fundamentals of thermodynamics tell you that heating overnight will cost more than switching off overnight and re-heating in the morning. Anyone who tells you otherwise doesn't understand basic physics.
