Ideal pool water temperature for swimming is between 80 and 90 degrees. Below 80 seems too cold and above 90 is too warm. During the summer months, for a pool that gets full sun most of the day, it is not uncommon for the temperature to shoot above 90 degrees. At Anchor Pools & Spas, we have some tips for you for cooling down your pool so you can enjoy resort-like living in your own backyard.
1. Install a reversible heat pump. All it takes to either heat or cool your pool with a reversible heat pump is a flip of the switch. They can be expensive to purchase and also expensive to run. Operating them uses a considerable amount of power. The up-side is that they are highly efficient in cooling down the pool water.
2. Partial drain and refill. You can partially drain your pool of some of the hot water and refill it with cooler fresh water. Whether this is a viable option depends on your water source. It may be too expensive of a method, and it is also wasteful. But, if it works for you, keep in mind you will have to rebalance the water chemistry of your pool water.
3. Use ice. Although this could work, it is almost a humorous suggestion. A 20,000-gallon pool needs 8,750 pounds of ice to lower the temperature by 10 degrees.
4. Use an evaporative cooler. Evaporative coolers are just what they sound like. They use evaporation to lower the pool water temperature. They are less costly to buy and operate than heat pumps, but they cannot be used as a heat pump in the winter. The water temperature may be lowered as much as 5 to 10 degrees, depending on the size of the cooler, the size of the pool, the ambient temperature, and the humidity.
5. Shade your pool. You may want to place shade umbrellas around the pool that will cover the water. Consider planting shade trees for next year, but choose the type of tree wisely. You don’t want to be cleaning leaves out of the pool every day once they start falling off in the autumn.
6. Use portable coolers around the pool area. Using these coolers, and misting the backyard area, may be highly effective. But, be extremely careful about where you plug them in, the type of plug you use, and keep them far enough away from the pool so there is absolutely no danger of them falling into the water and shocking or electrocuting swimmers.
7. Water Fountains. Not only are they esthetically pleasing, they really do help cool down the water temperature of your pool. The water action that fountains create causes evaporation and that is what helps cool your pool.
