If you're still using a single-speed pool pump, it may be working harder—and costing more—than it needs to. Variable speed pumps (VSPs) are becoming a popular alternative, not only because they’re quieter and more energy-efficient, but also because they can help homeowners save money in the long run.
Understanding how VSPs work, and how they compare to traditional models, can make choosing the right pump a lot easier. Here’s a closer look at how variable speed pumps support both your pool and your household budget.
Why Variable Speed Pumps Offer a Smarter Way to Circulate Water
Traditional single-speed pumps operate at one constant (and usually high) speed, regardless of what your pool actually needs. Variable speed pumps, on the other hand, allow you to adjust motor speed based on the task at hand.
This flexibility brings a few key advantages:
-
Lower energy use during everyday filtration
-
More efficient control for heating, cleaning, or running water features
-
Less wear on your pump and plumbing system
In fact, some states and municipalities now require VSPs to meet energy standards, making them not just a smart choice—but sometimes a necessary one.
A Simple Comparison: Single-Speed vs. Variable Speed
Let’s say you have a 20,000-gallon pool and run your single-speed pump for about 8 hours per day. That setup might use around 2,000 watts per hour. Over the course of a month:
Single-Speed Pump:
-
2,000 watts x 8 hours x 30 days = 480,000 watt-hours = 480 kWh
-
At $0.15/kWh, this adds up to about $72/month, or $864 per year
Now let’s compare that to a variable speed pump running at lower speeds for routine filtration:
Variable Speed Pump:
-
Averages around 500 watts/hour
-
500 watts x 8 hours x 30 days = 120,000 watt-hours = 120 kWh
-
That’s closer to $18/month, or $216 per year
Annual savings: $648
How Long Does It Take to Pay Off a Variable Speed Pump?
Most quality VSPs cost between $800 and $1,200. With energy savings of over $600 per year, many homeowners find that their pump pays for itself in under two years. Since these pumps typically last 10–15 years, that adds up to significant long-term savings.
Additional Ways VSPs Can Help Save (and Simplify)
-
Utility rebates: Many local programs offer rebates of $100–$300 for ENERGY STAR®-rated pumps
-
Lower maintenance costs: Reduced strain on plumbing and filters can lead to fewer repairs
-
Quieter operation: A lower hum means a more peaceful backyard experience
Tips to Maximize Your Pump’s Efficiency
Using your VSP wisely can make a big difference:
-
Set lower speeds for filtration and circulation whenever possible
-
Increase speed only for tasks like vacuuming or spa use
-
Keep your pool’s plumbing and filter system clean to reduce strain on the motor
