Department of Energy Pump Regulations

 

The Department of Energy (DOE) has set new efficiency regulations that state: “any pool pump manufactured after July 19, 2021, must comply with updated guidelines that meet minimum efficiency standards.” These new regulations do not just apply to pool filtration pumps.

 

All pumps are subject to the new DOE regulations, regardless of application.

 

Although the new regulations do not mention a variable speed pump, they do make it difficult for many single-speed and two-speed pumps to meet the new requirements. If they do, they probably will not be powerful enough for your pool.

 

Efficiency Standards:

The new federal regulations apply to self-priming filtration pumps (in-ground pool pumps) past a specified horsepower threshold. This threshold is measured with a different system than traditional motor horsepower. The new regulations state that self-priming filtration pumps, rated between 0.711 and 2.5 hydraulic horsepower, must meet the new threshold. If you convert this to threshold, the regulations apply to pumps between approximately 1 and 5 horsepower.

 

Just like with an inground pool, a variable speed for an above ground pool will save you money. Check to make sure that your pump's flow rates are close to your filter's flow rate, and that they do not exceed it on high speed by more than 10%-20%.

 

Pool pumps operate for multiple hours a day to provide a high flow rate for mixing and cleaning pool water. While they are the least expensive option, single speed pumps continuously run at full speed while powered on. In contrary, variable-speed pumps can operate at lower speeds for many hours, which can reduce energy usage by 40%-80%. Not only will switching to a variable speed pump reduce your energy bill, they are quieter, run cooler, and help increase the longevity of your other equipment with less stress of water pressure.

 

You, as a pool owner, are not mandated to change your single-speed pump, you just will no longer be able to purchase a replacement.

 

Single-speed pumps will continue to be sold on the internet and in store-fronts. The DOE is allowing suppliers to sell off their inventory, with no time limit of when these pumps must be sold. The new regulation states that manufacturers must stop making pumps that do not meet the new threshold requirements.

 

Pressure cleaner booster pumps are included in the new DOE regulations and must meet minimum efficiency requirements. However, most single speed pressure cleaner booster pumps will be compliant with the new efficiency standards. In addition, many non-self-priming pumps used for above ground pools will fall within the minimum efficiency standards for single speed pumps.

Here is the list the DOE stated as exemptions:

• Waterfall Pumps – must be labeled as waterfall pump 
• Integral Sand- and Cartridge-Filter Pool Pumps 
• Storable Electric Spa / Rigid Electric Spa Pumps 
• Pumps with 3-Phase Motors
