VAUGHN THERMAL MP55FHPT 50-Gallon is a heat pump (hybrid electric) water heater from VAUGHN THERMAL with a 55 gallon rated tank and a 62 gallon first-hour rating at a 3.3 UEF — 982 kWh/yr certified use, 54.5 in tall.
Our take
Vaughn's 55-gallon tank is the widest unit in the 50-gallon class at 30 inches across — half again the median diameter — housing a 3.30 UEF machine (30th percentile) that costs about $167 a year, $2 over the class median cost. The 62-gallon first-hour rating trails the median by 4. Where the spec sheet is ordinary, the format is not: 54.5 inches tall with that broad footprint, it fits under moderate ceilings that defeat the 63–66 inch slim towers. 240 V / 23 A, R-134a, 35 °F cutoff, no connectivity, single badge.
Best for: Moderate-height spaces that can spare a 30-inch circle of floor.
Trade-off: Below-median efficiency and delivery for the class.
