Most efficient 80-gallon electric water heaters

Electric tanks filed at 75 to 85 gallons, ranked by filed UEF inside each draw pattern.

40 80-gallon electric water heaters are on file. Ranked by filed UEF inside each draw pattern, the most efficient at the high draw pattern is the GE Profile PH80S10BNY01 (UEF 4.5).


Editor's note

Both heat pump and resistance tanks are in this list, because the registry files them as one type; the heat pumps rank first on UEF because they move heat rather than make it.


High draw pattern

a larger household, or one where showers and laundry overlap — 40 models, top 25 shown, highest UEF first.

How this list is ranked

One filed figure decides the order, inside one draw pattern at a time — the only scope where it compares. Models that file the same figure share a rank, shown as =N. A draw pattern is ranked only when it holds at least eight models and their figures spread by at least 8%; models named in a CPSC recall are left out.
