Noritz ME80HPT

It holds 74 gallons in the test, 6 gallons less than its 80-gallon sold size. It delivers 86 gallons of hot water in the test's first hour. Its tank holds 74 gallons, so reheating adds 12 gallons during the first hour. Among 481 heat pump models, 100 have a higher first-hour rating. The median heat pump model gives 72 gallons in the first hour of the test.

Under this basic model, 2 model numbers are ENERGY STAR certified. For each unit of energy it uses, 3.48 units end up in the hot water (its UEF). It moves heat from the air rather than making it, so its UEF passes 1. The daily hot water use in the test, called its draw pattern, was high. Of 237 heat pump models with the same draw pattern, 192 have a higher UEF and 42 a lower one. On its draw pattern, the median heat pump UEF is 3.88. While it reheats, the water gains 365% of the energy it uses (its recovery efficiency).

All of its test figures are shared by 2 other basic models. Of those, one or more are under the Hubbell and VAUGHN THERMAL brands. For the full group, see the Hubbell ME80HPT page.

In 17 states, 17 rebate programs may accept it. It may qualify for 5 more if it meets terms its figures do not show.
