Richmond Heat Pump 40-Gallon (10E40-HP5S30) is a heat pump (hybrid electric) water heater from Richmond with a 36 gallon rated tank and a 60 gallon first-hour rating at a 3.83 UEF — 859 kWh/yr certified use, 44.8 in tall.
Our take
Functionally Richmond's counterpart to the multi-brand RH375-30 compact — but certified with a 36-gallon tank: 3.83 UEF (79th percentile, about $146 a year, roughly $475 under a standard electric tank), a 60-gallon first-hour rating for 2–3 people, and a space-friendly 44.8-inch height with an 18-inch diameter. Standard 240 V / 21 A electrics on a 30 A breaker, R-134a refrigerant, 37 °F compressor cutoff, no smart features. Single badge in the certified data. If the 67-gallon-FHR 45-gallon variants fit your space, they are the stronger buy.
Best for: Compact, efficient service for a two-to-three-person home.
Trade-off: Its 45-gallon platform-mates deliver 7 more first-hour gallons for the same UEF.
