Pump Up Your Pool’s Efficiency

Swimming in Savings

With sunny weather year round, Californians spend lots of time outdoors and in pools. By changing the way you use your pool, you can give your pump a rest while still having fun in the sun! And when you purchase a new pump, you may qualify to get up to $200 in rebates!

Quick Tips

Set the timer to turn off your pool pump from 2 p.m. to 6 p.m. and watch its energy use dive as much as 60%.1

Filtering your pool for just 6 hours a day is an effective and efficient way to keep your pool clean.

Keep your drains and intake grates clean and clear to keep them running efficiently.


Pools and spas are fun and refreshing, but they can have a huge impact on your energy consumption and costs. Although you may use outdoor equipment less frequently than indoor appliances, you can still take advantage of energy-efficient options. Downsizing your pool pump may help, but you can also save by reducing the amount of time it runs, and by lowering the water temperature. These actions alone could save you up to 75% of annual pool energy consumption2 —that makes a splash in savings!

Pool Pumps: Size Matters

Pool pumps are the largest consumers of outdoor electricity, and you can save energy costs by downsizing your pool pump, selecting a variable speed pump and reducing the amount of time it runs. Select the smallest pump that will adequately clean your pool. Use a pool supplier’s design chart to determine the right size pump for your pool, or ask the pool supplier for assistance in selecting the correct pump

It’s in the Pipes

Install the pump’s pipes so they make smooth curves. By replacing elbow pipes with either 45-degree or flexible pipes, you’ll make the water flow more efficiently, decrease hydraulic resistance, and this could reduce electricity use by up to 40%.3

Cool the Pool

Most people prefer to keep their pool’s water temperature between 78°F and 82°F. However, you may be paying 10-30% more in energy costs for each degree higher you keep your pool’s temperature.4 Therefore, be sure to turn the heater down or off when you’re on vacation, or during cold weather when you’re not using your pool.

Consider Solar Heating

Using the sun to heat your pool is an options in California’s sunny climate, but if you choose to go solar, you may need a larger pump for the extra power needed to pump water through the collectors.

Cover It Up

A significant amount of pool energy is lost by evaporation at the surface level. Look for a transparent cover that will let the pool absorb heat from the sun as an outdoor pool absorbs the radiation it receives, allowing the heater to do less work.5

Use & Care

Proper purchase and use of your pool pump will maximize efficiency. Learn more about Pools & Spas: Use & Care, where to start, and how to use your pool and pump for the most savings.
