Energy use per year
928 kWh a year
Computed by this site from the registry's UEF and the federal test's daily hot-water draw for this draw pattern. What it costs depends on the electricity rate where you live.
This model is in the lowest quarter of its class for energy use. That is below the median of 3,493 kWh for the 452 models registered in the same heater type and draw pattern; it ranks 103 of 452, lowest energy first.
Among the 153 heat pump water heaters at this draw pattern alone, it ranks 103 by lowest yearly energy.

What the registry files
From DOE CCD · 2026-10-25
- UEF (Uniform Energy Factor) how much hot water you get for each unit of energy the heater uses
- 3.50 Compared only with other models registered as an electric tank at the medium draw pattern.
- Draw Pattern the standard daily usage profile DOE tests the unit against
- Medium
- First Hour Rating how many gallons of hot water the unit can deliver in one hour, starting from a full tank
- 67 gal
- Rated Storage Volume the tank size in gallons
- 45 gal Rated volume is the size the registry files. The number in a model name is the maker's nominal size and can differ: a "40-gallon" model may be rated at 36.
From ENERGY STAR · 2026-10-25
- On the market since (ENERGY STAR) the date the manufacturer told ENERGY STAR the model went on sale
- 2020-04-30
- Connected / demand response (ENERGY STAR) whether the unit can take signals from your utility to shift when it heats, and by which standard (such as CTA-2045)
- No
- Refrigerant and GWP (ENERGY STAR) the refrigerant a heat pump unit uses and its global warming potential, a leak's climate effect relative to carbon dioxide (CO2 = 1)
- R-134a, GWP 1430
