|Pool Pumps||Allows pool owner to vary pumping speed to meet different pool functions (e.g., filtering, cleaning) and save energy versus using a single higher speed to accommodate all pool functions.|
Key Product Criteria for ENERGY STAR Qualified Pool Pumps
|Single Speed Pump||EF ≥ 3.8 for the single speed
Energy Factor (EF) is the volume of water pumped in gallons per watt hour of electric energy consumed by the pump motor (gal/Wh).
|Multi-speed, Variable-speed, and Variable-flow pump||EF ≥ 3.8 for the most efficient speed
Most Efficient Speed: The speed with the highest Energy Factor for a given pump.
