Did you know there are more than 5 million in-ground pools installed across America, and over 50,000 new in-ground pools built annually? If you are (or are soon-to-be) a pool owner, keeping the water clean is probably a key consideration. That’s where the pool pump comes in– it re-circulates water through a filter to maintain water clarity and hygiene. All swimming pools have at least one recirculation pump, but many have multiple pumps.
Why should you care about your pool pump?
If you have a pool, the pool pump uses the most electricity of any single product in your home. They typically cost $450 a year to operate – much more than they need to. Conventional single-speed pool pumps are set to run at the higher speeds required of the pool cleaner and waste energy during filtration operation, which really only needs half the flow rate.
How can ENERGY STAR help?
An in-ground pool pump that has earned the ENERGY STAR label can run at different speeds and be programmed to match your pool’s needs with appropriate speed. The energy saved is considerable: reducing pump speed by one-half allows the pump to use just one-eighth as much energy. ENERGY STAR pool pumps are independently certified to deliver those energy savings while providing the performance you expect. In some cases the performance may exceed expectations—for instance, variable speed pumps that earn the label are much quieter.
How much money does an ENERGY STAR certified pool pump save annually?
There are two types of pool pumps that can earn the ENERGY STAR label: multi-speed and variable speed. Multi-speed pumps operate at two speeds and allow the pool owner to reduce the speed of the motor during the majority of its operation. Variable-speed pumps are the most efficient because they can be programmed to operate at many different speeds, even below half speed, depending on the pool usage. Both offer considerable energy savings over the more commonly used single-speed pump.
An ENERGY STAR certified “variable speed” pool pump will use 2,800 kWh less electricity per year, on average, equivalent to:
- $340 in savings
- 2.2 tons of reduced greenhouse gas emissions
An ENERGY STAR certified “multi-speed” pool pump will use 2,300 kWh less electricity per year, on average, equivalent to:
- $280 in savings
- 1.8 tons of reduced greenhouse gas emissions
This is money you can PUMP back into the family budget.
The energy savings are great … but is it worth it?
Even considering the extra money you might pay to buy them, ENERGY STAR certified pool pumps pay for themselves in about a year-and-a-half (less for multi-speed pumps). And that’s not all. Many utilities offer rebates for ENERGY STAR certified pool pumps. For example, Long Island Power Authority offers a $400 rebate. Check with your local utility.
By the way, you’re not just saving money, you’re helping the environment
If all pool pumps sold in the United States were ENERGY STAR certified, the energy cost savings would grow to about $110 million each year, and 1.5 billion pounds of annual greenhouse gas emissions would be prevented — equivalent to the emission from nearly 140,000 vehicles.
