Richmond PRO+G50-40N RH67 PD

This site calculated the 245 therms figure; the registry does not list it. It combines two inputs. One is the registry's UEF, the ratio of hot water delivered to energy used. The other is the daily hot-water draw that the DOE test sets for the high draw pattern. This model's UEF is 0.69. The underlying record comes from the DOE CCD, retrieved 2026-09-19. This model ranks 130th lowest in energy use among the 414 gas tank models registered at the high draw pattern. That puts it in the second-lowest quarter of its class for energy use. The figure applies only at the test's daily draw. This data does not give energy use at any other daily draw.

The high draw pattern represents a larger household, or one where showers and laundry overlap. This model's first hour rating, the gallons of hot water available in the first hour from a full tank, is 79 gallons. Its rated volume is 48 gallons. These two figures show how much hot water it can supply at a busy time. The annual energy figure does not show that. A plumber or seller checking a match can compare them with the same figures for the existing unit. If a household uses less hot water each day than the test's high draw, the 245 therms figure does not describe its likely use. The registry gives no figure for that case. To compare other models registered in the same class, use the same-class replacement search by model number.

This text does not state the running cost. It depends on the reader's state average residential gas price, so the page calculates it from the reader's ZIP. That means two households using the same 245 therms of natural gas a year can pay different amounts. The cost calculator for your own ZIP applies your state's rate to this model's figure. The steps are explained in how the annual cost is calculated. The installed price is shown in its own block with its source and date. It is a modeled installed-cost range, not a quote from an installer. The model's 130th place in its class is based on energy use only, not on cost.
