Can You Leave Pool Heater on Overnight

Can you leave pool heater on overnight? If you are the type of person that likes to take a dip in your pool or go for a swim the first thing in the morning, this might be one of the questions you’re wondering about. You may also like the water to be comfortably warm when doing so. The answer to this question is hard to give as a definite yes or no. That’s because it depends on how your swimming pool system is set up. There are certain situations where it’s ok to run your pool heaters at night and others when it’s not advisable. 

Situations Where You Can Run Your Pool Heater at Night

There are times when wondering can you leave pool heater on overnight that it’s ok to do. Most of the time this is for swimming pools that are covered. This includes both those types of pools that have automatic covers on them or what are known as solar blankets that are pulled across them at night. These stop rapid heat loss from happening, keep pool water from evaporating and have the extra benefit of keeping your swimming pool cleaner. If you live in an area where the ambient temperature change from day to night is not huge, then it’s ok to run your heater overnight too. 

Don’t Run your Swimming Pool Heater at Night if You don’t Have a Cover

When asking can you leave pool heater on overnight, the answer is definitely no if you have no swimming pool cover. Not only will it be tough to keep the heat in your pool on colder nights but you will also spend a fortune trying to heat your swimming pool. So unless you have money to burn, it’s best not to run your heater at night on an uncovered swimming pool.
