Quietest heat pump water heaters, by filed decibels
Heat pump models whose ENERGY STAR filing lists a sound level, quietest first inside each draw pattern.
106 heat pump water heaters that file a sound level are on file. Ranked by filed sound level inside each draw pattern, the lowest filed sound level at the high draw pattern is 37 dB, shared by 4 models.
Editor's note
Only about a third of heat pump models file a sound level with ENERGY STAR; a model missing here is unmeasured, not loud.
High draw pattern
a larger household, or one where showers and laundry overlap — 67 models, top 25 shown, lowest dB first.

Not ranked
Low draw pattern (1 models): fewer than eight models, too few to rank.
Medium draw pattern (38 models): the filed sound levels vary by only 7.0% — too close together to order meaningfully.
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.
