Variable-Speed Pumps Save Energy and Pool Maintenance Hassle

It’s Time to Say Goodbye to High Energy Bills


New Department of Energy (DOE) regulation means more pool owners will soon be switching to variable-speed (VS) pumps as their single-speed pool pumps fall out of compliance. Pool owners may be unaware of the real benefits that come along with implementing a VS pump over a single-speed pump. Because single-speed pumps are the least expensive pump option, switching over to a more costly piece of equipment may put a sour taste in customers’ mouths — even if it provides more cost savings and improvements to their pool’s quality in the long run.

To help educate and empower pool owners to make the right decision for their new pool pumps, dealers and retailers should learn more about the options available for VS pumps and how to communicate the full benefits to their customers, including energy cost savings and improved pool conditions.

#2 Energy Consumer in the House      

Behind heating and cooling, pool pumps can be the second highest energy consumer in the house. With single-speed pumps, there are only two settings: on or off. So, while these pumps are the least expensive, when they run, they run at full speed, which can cause excess wear and tear on equipment. And when they turn off to save energy, water is left stagnant and can become unsanitary.

As part of its new regulation, the DOE is updating its mandate on what is required to be listed on a pool pump label. Of those items listed on the label, one most commonly known by pool owners is the weighted energy factor (WEF). In fact, this measurement is very often compared to miles per gallon (MPG) in a car, making it easier for a pool owner to understand its importance in the conversation. But, as retailers know, energy savings in a pool goes beyond measuring WEF. Two additional considerations pool owners should keep in mind when identifying energy consumption for a VS pump are the hydraulic horsepower (HHP) and the total horsepower (THP).

Understanding the Labels

  • WEF: Measure of energy efficiency. The higher the WEF, the most efficient the pump. WEF is required to be labeled on a pump.
  • HHP: Measure of pump’s performance. The amount of water your pump can push to, and through, the pool. This is not equivalent to motor horsepower and is not required to be labeled on the pump, but Pentair does put it on its products.
  • THP: Measure of the total horsepower created at the motor shaft, not at the wet-end. This represents the potential output, not the actual output. THP is required to be labeled on the pump.

While the new DOE regulation aims to improve energy efficiency and increase visibility in the numbers behind energy consumption, there are specific VS and variable speed and flow pump products pool owners can implement to better manage their energy costs, saving them money long term.

Tackling Poor Pump Performance

In addition to high energy costs, pools with poor pump performance can face some unfortunate situations, such as unsanitary pool conditions, poor water quality, increased wear and tear, more frequent filter cleanings, shorter pump lifetime and a need to use more chlorine. Luckily, many of these challenges can be addressed with variable speed and flow pumps.

By incorporating VS pumps, pool owners will see energy and cost savings, along with higher performance, less noise, and a longer-lasting product compared to single-speed pumps. All these factors combine to create a better pool experience with improved circulation and less wear and tear on equipment.

Finding the Right Product

To choose the right products, pool owners should discuss their specific needs with a dealer or retailer who can give helpful recommendations and insights into products. Three products dealers should consider for their customers’ pools includes Pentair’s IntelliFlo® VSF Pump, SuperFlo® VST Pump and the IntelliPro® VSF Pump.

  • IntelliFlo VSF Pump: IntelliFlo is the first variable speed and flow pump that adjusts to changing system conditions. It maintains desired flow and performance by automatically adjusting its speed to compensate for filter loading, water features and more. Simply put, having an IntelliFlo VSF pump is like having cruise control for your pool.
  • SuperFlo VST Pump: Designed for practical pool owners, the SuperFlo VST pump has a dependable and robust totally enclosed fan cooled motor and can adapt to 115V or 230V and 50hz or 60hz power with no special wiring or switching.
  • IntelliPro VSF Pump: This innovative dual-technology pump ensures the desired flow and performance is maintained, even as a pool’s conditions change. Utilizing an IntelliPro VSF Pump helps ensure that other pool equipment performs at optimal levels as well.
