Richmond PROG50S-40N RH61
0.63 UEF DOE CCD · 2026-09-19Grade G: where this UEF sits among the 414 models in its class, lowest (G) to highest (A). A position, not an official label. How the grade is set
A gas tank, high draw pattern (a larger household, or one where showers and laundry overlap).
If you are checking the Richmond PROG50S-40N RH61, a gas tank water heater, it uses 269 therms of natural gas a year. That figure is at the high draw pattern, the standard daily hot-water usage DOE tests against. It sits 9 therms above the 260 therms median of the 414 gas tank models registered at that pattern.
Energy use per year
269 therms a year
Computed by this site from the registry's UEF and the federal test's daily hot-water draw for this draw pattern. What it costs depends on the natural gas rate where you live.
That is above the median of 260 therms for the 414 models registered in the same heater type and draw pattern; it ranks 320 of 414, lowest energy first.
Solid line: this model (269 therms). Dashed line: the class median.

The 269 therms figure is computed by this site. The registry does not publish it. 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 draw pattern. This model's UEF is 0.63. The registry record comes from the DOE CCD, retrieved 2026-09-19. The figure is in natural gas, and it holds only at the federal test's daily draw. This page does not have the unit's gas use at a lighter or heavier daily draw. The steps behind the figure are explained in how the annual cost is calculated.
The high draw pattern stands for a larger household, or one where showers and laundry overlap. At that pattern, this model's first hour rating, the gallons of hot water available in the first hour from a full tank, is 87 gallons. Its rated volume is 48 gallons. A plumber or homeowner matching a unit to a household can check it against those two figures. The energy figure describes a household that fits the high pattern. It does not apply to a household with lighter daily use, and no energy figure for that case is available here.
Within its class, this model ranks 320th of 414 for lowest energy use. That places it in the highest quarter of its class for energy use. A reader comparing this unit with lower-use gas tank models at the high pattern can find a same-class replacement by model number. The running cost is not given in this text. It depends on your state's average residential gas price, so the page calculates it from your ZIP. You can also use the cost calculator on your own ZIP. The installed price range has its own block, with its source and date. That range is a modeled installed cost, not a quote.
