FRIEDRICH PROG50-40N RH67 PDV

The annual figure of 245 therms comes from this site, not from the registry. It starts from the registry's UEF, the ratio of hot water delivered to energy used. The registry lists a UEF of 0.69 for this model. The site then applies the DOE test's daily hot-water draw for the high draw pattern. The result applies to natural gas and to that test draw only. The registry data behind it is DOE CCD, retrieved 2026-09-19. A home with different hot-water use will see a different total. The method behind the annual calculation is documented on its own page.

The class is the 414 models registered as a gas tank at the high draw pattern. This model sits 15 therms below the class median of 260 therms. It ranks 130th lowest in energy use, in the second-lowest quarter of its class. The comparison covers energy use only and does not measure how well the unit meets demand. The registry lists a first hour rating, the gallons of hot water available in the first hour from a full tank. It is 82 gallons, and the rated volume is 47 gallons. The high draw pattern describes a larger household, or one where showers and laundry overlap. The energy figure is computed for that kind of household only. The water heater selector filters by fuel, space and size.

The running cost is not stated here because it depends on your state's average residential gas price. The cost calculator uses your ZIP to apply that price to the 245 therms a year at the high draw pattern. The 15 therms gap to the class median converts to a different amount in each state. This page does not estimate any cost. The installed price appears in its own block, as a modeled installed-cost range with its source and date, not as a quote. A same-class replacement can be found by model number with the replacement finder. The registry does not give a measured figure for your own home, so actual use there is unknown.
