How can I cool the pool water down

Swimming Pool Water

You might be asking, if you’re shopping for a swimming pool, “How can I cool the pool water down? Should I get a heat pump, a heat pump with a chiller?” 

We talk to clients all the time who come back after the fact and they say, “You know what, we were really skeptical about spending a little bit more to have the ability to chill our pool, but, we are glad that we did it,” because here in St George Utah and lots of other states down south, the temperature during the summertime can easily reach 110 degrees. 

If you have a pool that is six and a half feet deep or less in-depth, then you’re more than likely going to run into the need to have to chill your water, unless, of course, you like your water to be 90 plus degrees. But let’s face it, there’s a big difference between 90-degree water and, say, 83-degree water. That seven degrees is a huge swing and can make all the difference in the world for your swimming pool experience.

Now, what else goes into affecting the water temperature on pools that are about six and a half feet deeper, less? Well, the color of the surface. You see, traditional gunite pools have, it’s just a white finish, that plaster’s a white finish. But if there’s a dye added to it, now your water could heat up a lot more quickly. The same for fiberglass pools. More often than not, the gel coat has a darker color to it, and these tools will heat up faster, the same with vinyl liner pools. So, you need to think about whether you want to add the ability to chill your water or not.

If you’re already adding a heater, you go with the heat pump, because it’s highly efficient in heating that water up. For $1,000 more, you could have the ability to cool that water down during the hot days of summer. If you add a heat pump but don’t opt for the chiller option, it’s far more costly to come back and swap that heat pump out for one with the chillers later. Spending that extra $1,000 bucks upfront is a smart investment, to ensure you have plenty of fun swimming in the hot summer months.  The heat pump can chill the water in reverse when its not being used as a heater. If you go with a gas heater, you will need to add a separate chiller which will add thousands and thousands of dollars on top of the gas heater. Heat pumps are great options as they can heat and cool the pool in one unit.

How cool should you keep your pool during the summer months? Most pool owners will agree that 84 degrees Fahrenheit is the most optimal temperature. Now cooling or heating your pool to 84 degrees can be costly depending on the outside temperature. So you might choose to have your pool at a different temperature to help save money on heating and cooling cost.
