Get Pumped for Summer with Tips to Make Your Swimming Pool More Energy-Efficient

family in poolWith summer just around the corner, many swimming pool owners are looking forward to some much-needed relaxation in their backyard oasis – but they are dreading the inevitable increase in their energy expenses. Owning a pool doesn’t necessarily have to be expensive, time consuming or a huge waste of energy. You can still have outdoor fun while championing smart energy use.

Make a splash with your energy savings this summer by soaking up a few tips to improve your pool’s energy efficiency:

Install an energy-saving pool pump and operate it efficiently

 Having an energy-efficient pool pump is an important part of the equation when considering pool maintenance options. Using a smaller, higher energy-efficient pump and operating it less frequently can help lower pool energy costs. We recommend putting pool pumps on timers with run times of 8-10 hours a day, depending on pool size.

Consider using a pool pump with variable speeds

  •  Since pool pumps are vital to performing so many pool functions, your pump’s speed is the first place to look for energy savings. The speed at which a pump operates has a significant impact on the amount of energy it consumes. There are three types of pumps: single-speed, two-speed, and variable-speed. All have electric motors that power them, so it’s important to understand how each of them function.
    •  Single-speed pool pumps operate at only one speed to power all pool functions – even those that do not require as much power. Single-speed pumps, by design, can’t change their flow rate so they must be sized to perform the most demanding tasks.
    • Two-speed pool pumps operate at either full speed (100%) or half-speed (50%). Because there are only two speed choices, it is difficult to fine-tune the flow rates required for maximum energy savings. However, when running at half-speed, a pump can provide significant energy savings, while still having the ability to run at full-speed when more water flow is needed.
    •  Variable-speed pool pumps operate over a range of speeds and can be “dialed-in” to the specific speeds needed for different functions such as basic circulation, heating, spa use, etc. These pumps allow homeowners to achieve the ideal filtration flow rate with the least amount of energy consumption.

Keep filters clear of debris


  •  Clogged filters force pool pumps to work even harder to circulate water. At first glance, a filter may not seem like an obvious spot to seek energy savings – that’s because the filter itself is not the energy guzzler; the culprit is the energy demands the filter makes on your pool pump. With this in mind, your choice of filter and its maintenance makes a difference in your quest for an fficient pool.

    As there are many factors (i.e., pool size, construction, etc.) that contribute to a pool’s energy consumption, we recommend that you consult your pool supply/service company for specific information about cost-savings.
