ENERGY STAR Certified Pool Pumps

Last updated 15 October 2026

Quiet residential pool equipment and surrounding deck

ENERGY STAR certified pool pumps have records for exact models. A brand logo or familiar family name is not enough. Match the full model number before using its test figure. Keep any suffix that states the voltage too.

Use EPA's official finder or dataset. Match the model and pump type. Check the market and voltage too. Save WEF and hydraulic horsepower with the check date. WEF describes efficiency in a defined test. It does not predict your yearly bill. A listed pump still needs to fit your pipes and active devices. The record also does not prove that a seller has it in stock.

Find ENERGY STAR certified pool pumps by exact identity

Start with the official product finder. Enter the full model number from the product or quote. You can also use the maker's spec sheet.

Keep prefixes such as EC. Keep suffixes that mark a revision too. A search result for a similar family is just a starting point.

The EPA dataset is a second official route to these records. It helps when the finder will not load. Each entry names the model and brand. It states the pump type, market and test figures too.

Save the exact entry. You do not need to copy a whole directory to compare a few models.

Compare the record with the maker's current model page. They answer different questions. EPA's row states the certified record. The current model page helps show what the maker sells and which manual fits it.

Neither source proves that a seller has stock. Nor does it settle which warranty terms apply to your sale.

ENERGY STAR certified pool pumps: dated record examples

These EPA dataset entries demonstrate identity matching. They are not ranked picks and do not imply that these pumps suit the same duty.

EPA product ID Exact record model Model name Reported WEF, kgal/kWh Hydraulic HP
2371769 EC-342001 Pentair SuperFlo VST 8.600 1.001
2507556 SP2670020VSP (115V) Hayward Super Pump VS 700 11.700 0.490
2507558 SP2670020VSP (230V) Hayward Super Pump VS 700 8.900 0.831

All three records list the United States as a market. The Hayward rows show why voltage labels matter. Drop that part of the name and two records can look like one. That would be misleading. Do not take the larger WEF and apply it to both voltage conditions.

The Pentair example is SuperFlo VST. It is not the archived SuperFlo VS used elsewhere for a curve example. A similar name does not make the curves the same. It does not make measured points or controls the same either. Use the exact model through the whole comparison.

Read WEF without turning it into a promise

Weighted Energy Factor, or WEF, reports efficiency on a defined test basis. EPA's field definitions give its unit as thousands of gallons per kWh. It ties water moved to input energy. It is not horsepower. It is not a daily run time either.

A higher WEF can mean more water moved per unit of energy in that test. Your home circuit may have a different flow. It may not give the same saving. Your pump runs where its curve meets the system curve. Your schedule then sets how long it spends at each duty.

Do not divide a season's gallons by a directory WEF and call it a measured bill. The test's duty points and weighting may differ from your use. Use measured electricity usage for your schedule. Keep the test record as one field in the model comparison.

Hydraulic horsepower is a different field

Hydraulic horsepower describes power passed to the water at the stated duty. It differs from the motor's rated horsepower. A table can show both without a mistake. Keep the labels in your notes so the two figures are not confused.

Do not compare pumps by one horsepower label and ignore head and flow. The pool pump size calculator starts with the task you need. It shows which circuit data is missing. An EPA record cannot fill in unknown head for your pool.

The dataset has measured points for flow and head. It also has speed and input-power fields. These are standard-test points. They show what the record covers.

A few points are not a full maker's curve. Do not extend them past the tested range to approve a flow limit.

Compare records on the same basis

First match pump type. A pressure-cleaner booster pump does a different job from a pool filter pump. A self-priming record also differs from a non-self-priming record. Read the type before you sort a column of WEF numbers. A high number in the wrong class does not settle your choice.

Next keep the voltage condition and hydraulic duty. The table has unequal hydraulic horsepower on purpose. It shows why a bare WEF ranking is weak. The 115V row has a greater WEF. That does not prove it can replace the 230V row at every flow and head you might need.

Finally check the controls and actual load. A certified pump may still fail to work with your old control system. It may need a different supported link. A timer's contact rating does not prove that it can send speed commands. Those are separate checks.

Use the current specification owner

The ENERGY STAR partner page points to the current Version 3.1 specification on the check date. Follow that current link rather than treating an old search-result PDF as the active criteria.

An archived Version 2 table can still appear on a related page. That does not make it the current rule. If two pages differ, keep the exact version with the model record you use. Do not mix thresholds from different versions. Follow the current specification link for the current criteria.

This guide explains how to read official evidence. It does not certify a new pump. It does not give an EPA badge to an unlisted product. The site is an independent utility. EPA's programme owns the certification record.

Certification versus personal energy use

For your own comparison, record input watts and actual GPM for each period. Include priming and known standby use. Compare equal water movement. Match heater and cleaner service too. A lower energy total needs to serve the same useful duty before it shows a saving for that task.

Use the kWh calculator for energy and the runtime calculator for the water moved. Keep tariffs separate from efficiency: two owners with identical equipment can pay different amounts per kWh.

A rebate is a separate question. The official record does not prove that you meet a utility programme's terms. Check its dates and territory. Check the fitting rules too.

Subtract a rebate only when the current terms apply to you. An unknown rebate is not a saving.

Use a record match to narrow the shortlist

A model match answers the certification question for that record. It does not settle the purchase. Keep the matching code beside the offered unit, then use its manual and curve to check the actual duty. If the seller changes the code, repeat the match before carrying an efficiency comparison into the new proposal.

When a family page names several supplies, keep the condition from the directory row with its figure. Do not combine a favourable test result from one row with a convenient supply or control from another. That would describe a product the record never identified. A missing exact match is an unresolved field, rather than evidence that the whole family is either certified or excluded.

If a record changes later, retain enough of the earlier identification to explain which comparison needs updating. The product ID and complete model help distinguish a changed entry from a different unit. Recheck the shortlist's certification claim without rewriting measured energy or a documented curve result that came from another source.

Keep a compact verification record

Save the full model string and EPA product ID. Keep the voltage condition with the pump type and market. Add WEF with its unit. Add hydraulic horsepower with its label.

Save the URL and check date. Keep the matching manual too. That lets you repeat the check later.

If a seller shortens the name, ask for the full code. Do that before you compare models. A photo or broad series name may hide a revision. Pumps in similar cartons do not have to share the same record. The code is a better check than the box colour.

Use this checklist before choosing equipment:

  • Exact model and voltage match, with no omitted prefix or suffix.
  • Official certification record and its product ID retained.
  • Current manufacturer manual and complete duty curve identified.
  • Actual circuit head, flow and device limits documented.
  • Control interface and sales-channel warranty checked separately.

FAQ

What should I do if the records do not agree?

Keep both source titles and check dates. Compare the full model strings and voltage conditions first. A new brochure might describe a revised unit. The directory may refer to another record. That is only a possible cause. Confirm it before you use it to explain the gap. Until then, show both figures separately.

Do not average WEF figures that conflict. Do not take the larger one as the answer you prefer. Use the official record for a claim about certification. Use the correct manual for how the model runs. A source gap should narrow the claim. It should not become a reason to promise more.

Does certification cover every pump from a brand?

No. Match the exact record. A maker can sell several families and revisions. Their test figures and controls can differ. They may serve different duties too. A claim about the whole brand hides that. Keep the full model and voltage with the record. Then check the unit the seller offers.

Is a listed model necessarily available today?

A directory entry does not prove current stock. Check the maker's current US catalogue. Check the exact model offered by the seller too. The table here shows how to match an EPA record. It is not a stock report. It does not promise that a listed model can be bought through a given channel.

Can WEF predict annual electricity expense?

Not on its own. Yearly cost needs the actual schedule and input energy. It needs your tariff too. WEF uses a defined test that can differ from your circuit. Keep it as one comparison field. Then measure or document the duty the pump will serve.

Is the highest WEF always the right choice?

First check that the pump meets the flow you need at head. Make sure it stays within device limits. Check controls and voltage too. A high WEF for a different class or duty cannot replace those checks. Rank models only once they suit the same stated task.

If your next purchase is a separate control, compare the digital pool pump timer choices by enclosure, motor load and supported interface. Certification of the pump does not establish timer compatibility.

Verdict on certified pool pumps

Check ENERGY STAR certified pool pumps by exact record. Keep the model and test basis with the actual duty. The table keeps each named record separate from the actual duty. Report a changed record with its product ID and source. That makes the claim easier to find and correct.
