Richmond PROG40-38N RH62

This site computed the 191 therms figure; the registry did not. It combines the registry's UEF, the ratio of hot water delivered to energy used, with the DOE test's daily hot-water draw. This model's UEF is 0.58. The 288 models registered as a gas tank at the medium draw pattern form its class. Within that class, it ranks 231st for lowest energy use. That places it in the highest quarter of its class for energy use. The registry values come from the DOE CCD, retrieved 2026-09-19. Each input is listed on the page explaining how the annual cost is calculated.

The medium draw pattern represents a typical household on a busy morning, and the 191 therms figure applies only to that pattern. This unit has a rated volume of 38 gallons. Its first hour rating, the gallons of hot water available in the first hour from a full tank, is 64 gallons. A plumber or seller checking a home with medium-pattern use can compare those two figures with that home's peak demand. The 191 therms figure does not apply to a household that draws more or less hot water than the medium pattern. This page does not have this model's energy use at any other draw pattern, so that value is not available here. To compare other gas tank units at the same draw pattern, find a same-class replacement by model number.

This text gives no running cost, because the cost depends on your state's average residential gas price. The page calculates it from your ZIP instead. The cost calculator on your own ZIP applies your rate to the 191 therms figure. The same rate also prices the 6 therms gap between this model and the class median, at the medium draw pattern. Because the price differs by state, the same 191 therms does not cost the same amount in every ZIP. The installed price range appears in its own block, with its source and date. It is a modeled installed-cost range, not a quote. This text keeps energy use and installed price separate and does not combine them.
