Richmond PROG40-40N RH67 PV

The 242 therms figure is computed by this site, not taken 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 high pattern. This model's UEF is 0.7. The source is the DOE Compliance Certification Database, retrieved 2026-09-19. The figure holds only at the federal test's daily draw. A household that uses more or less hot water will use a different amount of gas, and the registry does not say how much. At the test's draw, its rank of 90th of 414 places it in the lowest quarter of its class for energy use. The steps behind the number are set out in how the annual energy and cost are calculated.

The high draw pattern describes a larger household, or one where showers and laundry overlap. The registry lists a first hour rating, the gallons of hot water available in the first hour from a full tank, of 79 gallons for this model. Its rated volume is 38 gallons. The class it is compared with is the 414 models registered as a gas tank at the high pattern. Against that group, at the test's daily draw, it uses 18 therms a year less than the median of 260 therms. A plumber, seller or homeowner checking a label can match these values against the registry entry. For another model in the same class, use find a same-class replacement by model number.

The 242 therms figure does not describe this model at a different draw pattern. Models tested at other patterns sit in other classes, and this model's energy use at those patterns is not available here. The text also states no running cost. That cost depends on your state's average residential gas price, so the page computes it from your ZIP instead. At the test's draw, the gap of 18 therms a year below the class median is worth more where gas costs more. To see the cost on your own rate, open the cost calculator for your ZIP. The modeled installed-cost range appears in its own block on this page, with its source and date, and is not a quote.
