A smarter, more efficient future for every pool owner starts with the Department of Energy and WEF regulations.
If you're planning to upgrade your pool pump or build a new pool, there's an important update you should know about. As of September 29 2025, the U.S. Department of Energy (DOE) has rolled out new energy-efficiency regulations that are reshaping how pool pumps are designed, sold, and installed across the country.
For homeowners, that means single-speed pumps are being phased out. For pool builders and trade professionals, it means ensuring every project meets current DOE compliance standards. And for energy-conscious buyers, it means today's variable-speed pumps deliver record-setting efficiency and long-term savings.
The DOE's Dedicated Purpose Pool Pump (DP3) rule is now in effect, setting strict performance benchmarks for all new pool pumps sold in the United States.
Here's where things stand:
Why this matters:
Older fixed-speed pumps run at full power all the time, wasting electricity. The DOE's new standards ensure every new pool pump operates intelligently—delivering the right flow rate with minimal energy use.
For builders and installers: Choosing DOE-compliant pumps such as Madimack's InverFLOW range helps future-proof your installations, pass inspections, and meet client expectations for performance and sustainability.
The Weighted Energy Factor (WEF) is the equivalent of miles-per-gallon metric for pool pumps. It measures how much water a pump can move per unit of energy—the higher the WEF, the more efficient the pump.
For context:
For energy-conscious homeowners, this translates into real savings. A variable-speed pump operating at lower speeds for longer periods can cut electricity use by up to 70–80%, saving an estimated $500–$600 per year on energy bills for the average U.S. pool.
| Feature | Single-Speed Pump | Variable-Speed Pump |
|---|---|---|
| Speed | Fixed (100%) | Adjustable multi-speed |
| WEF Rating | 2 – 3 (non-compliant) | 7 – 12+ (DOE-compliant) |
| Energy Use | High | Up to 80% less |
| Noise Level | Constant and loud | Whisper-quiet |
| Compliance Status | Being phased out | Current and future-ready |
For trade professionals: Variable-speed pumps aren’t just compliant—they’re the new industry standard. Installing them ensures your projects remain within DOE regulations through 2027 and beyond.
At Madimack, innovation and efficiency go hand in hand. Our InverFLOW series of variable-speed pumps are fully DOE-compliant—and they don't just meet the standard, they outperform it.
| Model | WEF Rating | DOE Status |
|---|---|---|
| InverFLOW Plus 1HP | 115v/11.7 ; 230v/11.1 | Exceeds Standard |
| InverFLOW Plus 1.5HP | 115v/12.2 ; 230v/10.9 | Exceeds Standard |
| InverFLOW Plus 2HP | 115v/12.6 ; 230v/11.4 | Exceeds Standard |
These ratings place Madimack well above the DOE minimum—and ahead of other brands.
Each pump features:
For homeowners: You gain top-tier performance and measurable savings.
For builders: You gain confidence that every installation is compliant, efficient, and built to last.
