If your pool pump runs at one speed all day, it may use more electricity than your pool needs for routine filtration. A variable-speed pump lets you run a lower speed for everyday circulation and schedule higher flow when a cleaner, heater, or water feature needs it.
Estimate the savings for your pool
Start with the watts the pump actually draws and the hours it runs at each speed. Divide watts by 1,000 to get kilowatts, then multiply by hours to get kilowatt-hours (kWh). Add the daily totals and multiply by the electricity rate on your bill. If your rate changes by time of day, price each part of the schedule separately.
For example, if your current schedule uses 12 kWh a day and a new schedule uses 8 kWh, the difference is 4 kWh a day. At an example rate of 15 cents per kWh, that works out to about $18 over 30 days. Your actual savings depend on your equipment, schedule, and utility rate.
Choose a speed that suits your equipment
A pool heater, salt system, or cleaner may require a minimum flow. Before changing speeds, check the equipment manuals or have a technician verify the flow. If you already have a variable-speed pump, reviewing its schedule is a good first step before considering a replacement.
