A. O. Smith Heat Pump 80-Gallon (HP1080H45DV 1) is a heat pump (hybrid electric) water heater from A. O. Smith with a 82 gallon rated tank and a 86 gallon first-hour rating at a 3.45 UEF — 1387 kWh/yr certified use, 69 in tall.
Our take
Fifteen catalog listings under 6 brand names share this certification — the volume configuration of A. O. Smith's big 82-gallon tank. The certified spec is bottom-quartile: 3.45 UEF, about $236 a year, 45 °F compressor cutoff, and 233% recovery efficiency tied for the class floor, with an 86-gallon first-hour rating 2 under the median. Physically it matches its platform: 69 by 27 inches, 240 V at 22 A. No connectivity. The breadth of badges is the story here; the numbers argue for spending up to the HPS10 trim when prices are close.
Best for: Six-badge price-shopping on a big-tank platform.
Trade-off: Bottom-quartile efficiency and the platform's weak cold behavior.
