Bradford White RE2HP80**-1NCTT

It holds 75 gallons in the test, 5 gallons less than its 80-gallon sold size. Starting full, it gives 88 gallons of hot water in its first hour of use. Its tank holds 75 gallons, so reheating adds 13 gallons during the first hour. Among 481 heat pump models, 65 have a higher first-hour rating. The median heat pump model gives 72 gallons in the first hour of the test.

The single model number sold under it is ENERGY STAR certified. In the test, it gives 4.00 units of hot water energy per unit it uses (its UEF). Pulling heat from the air lets its UEF pass 1. In the test, daily hot water use was set to high (its draw pattern). Of 237 heat pump models with the same draw pattern, 70 have a higher UEF and 141 a lower one. For its type and draw pattern, the UEF runs from 2.85 to 4.95. When it reheats water in the test, the water gains 448% of the energy it uses.

Its test figures match those of one other basic model. That one is listed under the JETGLAS brand.
