VAUGHN THERMAL MP120FHPT 80-Gallon is a heat pump (hybrid electric) water heater from VAUGHN THERMAL with a 119 gallon rated tank and a 115 gallon first-hour rating at a 3.5 UEF — 1418 kWh/yr certified use, 86 in tall.
Our take
Vaughn's integrated jumbo pairs a 119-gallon tank with a 115-gallon first-hour rating — fourth-best in the database — in a 86-inch, 30-inch-diameter cylinder that is the second-tallest unit certified. Efficiency is mid-low: 3.50 UEF (36th percentile) at about $241 a year, $24 over the class median. Unlike the split-system jumbos it needs no outdoor unit, just a very tall room and a 240 V / 23 A circuit. R-134a, 35 °F cutoff, 361% recovery, no connectivity, single badge. The all-in-one huge-buffer option, priced in ceiling height.
Best for: Jumbo stored capacity without split-system installation.
Trade-off: Seven-plus feet tall and below-median efficiency.
