120-volt plug-in heat pump water heaters on file

Heat pump models whose ENERGY STAR filing lists a 120 V input — the kind that can run from a standard outlet instead of a new 240 V circuit.

39 registered models are 120-volt plug-in heat pump water heaters. Their filed UEF runs from 2.8 to 3.5 across 3 draw patterns. Each is listed below with its yearly energy, and compared only with others of the same draw pattern.


Other collections


Low draw pattern

a one- or two-person household — 5 models, lowest yearly energy first.


Medium draw pattern

a typical three- or four-person household, about 55 gallons on a busy morning — 18 models, lowest yearly energy first.


High draw pattern

a larger household, or one where showers and laundry overlap — 16 models, lowest yearly energy first.
