How to make your pool more energy efficient

Swimming pools require a ton of energy to heat and operate. Here’s how to make it less costly for you and the environment.

• Use a solar cover. It’ll capture the sun’s heat during the day and help maintain the water’s temperature at night. To maximize the benefits, keep your pool covered for at least 16 hours a day. A solar cover also allows you to conserve water (and the pool chemicals in it) by reducing evaporation.

• Install an efficient pump. Water needs to circulate through the pump faster for cleaning than it does for filtration. A variable or two-speed system automatically adjusts the flow rate based on its operation. An in-ground pool will use up to 65 percent less energy if an Energy Star certified pump is installed.

• Opt for a heat pump. This type of pump draws considerably less electricity because it mostly relies on ambient summer air to heat the pool’s water. For increased energy savings, lower the programmed temperature by a few degrees.

Even without investing in this equipment, you can reduce the amount of energy it takes to maintain your pool. Set up a timer on the pump so it’ll turn it off periodically. This allows the pump to use less power without compromising water quality.

Hot tubs
Ideally, hot tubs should be sheltered from the elements, particularly the wind. Choose a sturdy, well-insulated cover and make sure to close it after you use the hot tub. If you know you won’t be using it for a while, set it to sleep mode. Shut it off completely for the winter.
