If you have booked a Florida villa to rent from October to April with pool heating and want to have a nice warm pool we recommend you put the pool cover on when ever you are not swimming.
When ever the air temperature is below the temperature of the pool (85F on average) you are losing heat so it’s essential you put the pool cover on especially in January and February when the average day temp is 65F-70F and at night is can get in to the 30’s.
Most pool pumps run from 8-9am until 5-6pm and the pool heater will only run when the pump is on so over night the pool blanket is the only thing to stop you losing all the heat and it normally does a pretty good job but make sure it’s on properly.
One other thing to note is that most pool heaters are electric and not gas so they don’t have a flame. They take heat from the air outside (also known as heat exchangers) so if it’s very cold outside (below 50F) they may not produce any heat even if it runs all day.
So on cold days it’s even more important to keep the pool blanket/cover on when ever you are not swimming.
For Orlando Villas with a spa the process is the same so if you are trying to use it on a cold day/night it may take a long time to get hot if at all.
