GE Profile Heat Pump 40-Gallon (PF40S10FPY01) is a heat pump (hybrid electric) water heater from GE Profile with a 40 gallon rated tank and a 46 gallon first-hour rating at a 3.1 UEF — 724 kWh/yr certified use, 39.4 in tall.
Our take
GE's 120-volt plug-in draws 7.5 A on a shared circuit — a 10 A breaker calculation — and stands just 39.4 inches, second-shortest in the class. It also uses R-1234yf, an ultra-low-GWP refrigerant almost nothing else in this cohort has. The certified capacity numbers tell you who it is for: 46 first-hour gallons, a Low draw pattern, 1–2 people. Annual cost is about $123 — the cheapest in the 40-gallon class — roughly $300 under a comparable standard electric tank. Connected-capable, single badge. Physics, not corner-cutting, sets the limits here.
Best for: Small households electrifying without a panel upgrade.
Trade-off: Capacity is honest but small — surges will outrun 46 first-hour gallons.
