Having recently repaired our single speed pool pump motor (replaced start capacitor), it got me curious about the new efficiency standards coming in July 2021.
The reading I’ve done on this has been a little confusing at times, but this is what I’ve figured out so far (please correct me if wrong).
The new regulation applies to the manufacturing of pumps/motors. Existing stock can still be sold after the effective date until it runs out. It doesn’t specify what type of pump/motor must be used (single speed, variable speed, etc), it says they must meet new efficiency standards. Some sites say only variable speed pumps/motors currently meet the new standard, others say some single speed units also meet the new standard. To add to the confusion, apparently the regulation doesn’t yet address replacement motors.
We have Hayward equipment, including a single speed Super Pump, model # SP2607X10, so out of curiosity I checked out their site to see what it said.

I was surprised to see our pump/motor model on the list of single speed units that comply with the new regulation. Reading further, it seems units under THP of 1.15 aren’t affected by the new regulation. The THP on our Super Pump is 1.10, so I guess it just squeaks in under the wire.
I checked our power bills to see how much our current setup is costing to run (1HP Super Pump, booster pump for cleaner, and SWCG). Running the pump 10hrs a day, booster 2hrs a day, SWCG set 50-60%, it adds about $35 a month to our bill, so about $175 a season. This makes me question if the ROI we would see is significant enough if we switched to a variable speed unit when it comes time to replace ours (hopefully no time soon).
IMO, if your building a new pool, then going for the latest, most efficient pumps is the way to go. But if replacing an existing unit, it’s not as clear cut; individual circumstances seem to vary widely.
It’ll be interesting to see how this all shakes out.
Thoughts? Corrections?
