Richmond PROE50 M2 RH95

This site computes the 3,493 kWh figure. The registry does not publish it. The figure combines the registry's UEF, the ratio of hot water delivered to energy used, with the DOE test's daily hot-water draw. For this model the registry lists a UEF of 0.93, taken from the DOE CCD on 2026-09-19. The draw comes from the medium pattern, which DOE sets for a typical mid-size household. The annual figure holds only at that test draw. A household that uses more or less hot water each day will get a different annual total. This page cannot say how large that difference would be. The figure covers electricity only, because this model is an electric tank.

This model ranks 153rd lowest in energy use among the 426 models registered as an electric tank at the medium draw pattern. That puts it in the second-lowest quarter of its class. At the test's draw, it uses 38 kWh a year less than the 3,531 kWh class median. Its first hour rating, the gallons of hot water available in the first hour from a full tank, is 62 gallons. The rated volume is 45 gallons. It suits a home whose busiest hour needs no more than that first hour rating. That rating does not cover a home that needs more hot water in its peak hour. To compare other sizes or fuels, use the water heater selector by fuel, space and size.

The running cost is not stated here because it depends on your own utility's electricity rate. The page works it out from your ZIP, using the 3,493 kWh figure at the medium draw pattern. You can enter your ZIP in the running cost calculator for your own ZIP to see that cost at your tariff. The steps are set out in how the annual running cost is calculated. Your rate also decides how much this model's 38 kWh gap below the class median is worth to you. The installed price has its own block on this page. It is a modeled range with its source and date, and it is not a quote.
