GE Profile Heat Pump 40-Gallon (PH40S10BPY01) is a heat pump (hybrid electric) water heater from GE Profile with a 40 gallon rated tank and a 64 gallon first-hour rating at a 4.2 UEF — 773 kWh/yr certified use, 39.4 in tall.
Our take
Top of the 40-gallon heat-pump class on efficiency: 4.20 UEF, no cohort-mate matches it, worth about $131 a year — roughly $480 less than a standard electric tank of the same size and $15 under the class median. It packages that into a 39.4-inch height (second-shortest here) with a 64-gallon first-hour rating right at the median, R-1234yf ultra-low-GWP refrigerant, 499% recovery efficiency, and app connectivity. The 240 V / 23 A circuit is class-standard. GE Profile badge only; nothing else in this size class posts these numbers.
Best for: Best-in-class efficiency in a short, closet-friendly body.
Trade-off: Single-badge product — no rebrand pricing pressure in the certified data.
