Richmond PROG50-34U RH EC1
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 PROG50-34U RH EC1, this gas tank heater uses 269 therms of natural gas a year. That figure belongs to 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 registry does not print the 269 therms figure. This site computed it from the model's UEF, the ratio of hot water delivered to energy used, and the DOE test's daily hot-water draw for the high pattern. The registry lists a UEF of 0.63 for this model. The data comes from the DOE CCD and was retrieved on 2026-09-19. The 414 gas tank models registered at the high draw pattern form its comparison class. On energy use, this model ranks 320th lowest in that class. That puts it in the highest quarter of its class for energy use. The figure holds only at the federal test's daily draw. This page has no energy figure for a household that draws a different amount. The steps are set out in how this site calculates the annual figure.
The high draw pattern stands for a larger household, or one where showers and laundry overlap. The registry lists its first hour rating, the gallons of hot water available in the first hour from a full tank, as 80 gallons. Its rated volume is 48 gallons. A plumber or seller can check both figures against the unit being replaced. A smaller household with a lighter daily draw falls outside the test condition behind the 269 therms figure. For that case, this page has no energy figure. If the old unit was also a gas tank at the high draw pattern, same-class replacements by model number lists the other models in this class. For a different fuel or tank size, use the water heater selector by fuel, space and size.
This text does not state the running cost. It depends on your state's average residential gas price, so the page computes it from your ZIP. The page applies that rate to the 269 therms figure. The 9 therms gap to the class median is a difference in therms. Its cost also depends on your own rate, so this text does not state it. The running-cost calculator for your ZIP shows the result for your state. The installed-cost range has its own block on this page, with its source and date. That range is modeled, not a quote. Both the running cost and the installed range assume the high draw pattern behind the 269 therms figure.
