Richmond PROE40 T2 RH95

This site calculated the 3,493 kWh figure; it is not copied from the registry. It combines the registry's UEF, the ratio of hot water delivered to energy used, with the DOE test's daily hot-water draw for the medium draw pattern. For this model the UEF is 0.93, taken from the DOE CCD, which we retrieved on 2026-09-19. The medium pattern represents a typical mid-sized household with a busy morning of hot-water use. If a home uses more or less hot water than the test assumes, its actual yearly use will differ from 3,493 kWh. The 38 kWh gap to the class median of 3,531 kWh also holds only at that same test draw.

The rated volume of this model is 36 gallons. Its first hour rating, the gallons of hot water available in the first hour from a full tank, is 55 gallons. A household whose busy-morning use is close to the medium draw pattern matches the condition behind 3,493 kWh. A household that needs more than 55 gallons in its busiest hour falls outside that condition. The registry data on this page do not show how the unit performs in that case. Among 426 medium-draw electric tanks, it ranks 153rd lowest in energy use, which puts it in the second-lowest quarter of its class. A plumber or seller can find a same-class replacement by model number. For another fuel or tank size, use the water heater selector by fuel, space and size.

This text does not give a running cost, because that cost depends on the electricity tariff of your own utility. Instead, the page works it out from your ZIP code by applying your rate to 3,493 kWh a year at the medium draw pattern. You can repeat that with the cost calculator for your own ZIP. The page on how the annual cost is calculated explains each step. At the same tariff and the same test draw, this unit costs less per year than a median unit by the price of 38 kWh at your rate. The installed price range appears in its own block, with its source and date. It is a modeled installed-cost range, not a quote.
