Rheem PROG50-42N RH67 PV

The registry does not print the 249 therms figure. This site computed it from the registry's UEF, the ratio of hot water delivered to energy used. The second input is the DOE test's daily hot-water draw for the high draw pattern. For this model the UEF is 0.68, taken from the DOE CCD and retrieved 2026-09-19. The result holds only at that test draw. This page does not have this model's energy use in a home with a different hot-water demand. The steps are set out in how the annual energy and cost figures are calculated.

The high draw pattern describes a larger household, or one where showers and laundry overlap. This model lists a first hour rating, the gallons of hot water available in the first hour from a full tank, of 78 gallons. Its rated volume is 48 gallons. It is compared only with the 414 models registered as a gas tank at the high draw pattern. Its rank, given above, places it in the second-lowest quarter of that class for energy use, not at the lowest end. Models ranked ahead of it in the class use less energy at the same test draw. This page does not give a figure for a smaller household with a lighter draw. To compare other models, use the water heater selector by fuel, space and size.

This text does not state a running cost for the PROG50-42N RH67 PV. The cost depends on your state's average residential gas price. The page works it out from your ZIP in the cost calculator for your own ZIP. The cost value of the 11 therms gap below the class median also depends on that rate, so it is not given here. The installed price range appears in its own block, with its source and date. That range is a modeled installed cost, not a quote. If you are matching an existing unit, you can find a same-class replacement by model number.
