Richmond PROG40S-36N RH67 PV
0.65 UEF DOE CCD · 2026-09-19Grade D: where this UEF sits among the 288 models in its class, lowest (G) to highest (A). A position, not an official label. How the grade is set
A gas tank, medium draw pattern (a typical three- or four-person household, about 55 gallons on a busy morning).
If you are verifying the Richmond PROG40S-36N RH67 PV, a gas tank heater, it uses 171 therms of natural gas a year. That figure belongs to the medium draw pattern, the standard daily hot-water usage DOE tests against. It sits 14 therms below the 185 therms median of its class.
Energy use per year
171 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 below the median of 185 therms for the 288 models registered in the same heater type and draw pattern; it ranks 33 of 288, lowest energy first.
Solid line: this model (171 therms). Dashed line: the class median.

The 171 therms figure is computed by this site, not taken from the registry. 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 medium draw pattern. This model's UEF is 0.65. The source is the DOE Compliance Certification Database, retrieved 2026-09-19. Among the 288 models registered as a gas tank at the medium draw pattern, this model ranks 33rd lowest in energy use. That places it in the lowest quarter of its class for energy use. The data here gives no figure for other draw patterns, so the 14 therms gap to the 185 therms median holds only at the medium one. The site explains how the annual figure is calculated.
The medium draw pattern represents a typical household's daily hot-water use, including a busy morning. This model's first hour rating, the gallons of hot water available in the first hour from a full tank, is 66 gallons. Its rated volume is 39 gallons. A household whose busiest hour stays within 66 gallons matches the conditions behind the 171 therms figure. A household that regularly needs more than 66 gallons in its busiest hour falls outside the test that produced it. The registry does not say how this model performs under heavier or lighter use than the medium draw pattern. If you are matching a unit being replaced, you can find a same-class replacement by model number. You can also compare other units in the selector by fuel, space and size.
This page does not state a running cost in the text. The cost of 171 therms of natural gas depends on your state's average residential gas price. For that reason, the page computes the cost from your ZIP code. The cost calculator on your own ZIP applies that rate to this model's annual use. This model uses 14 therms less than the 185 therms class median. At any single gas rate, its yearly cost is lower than a median model's by the price of that 14 therms. The installed price appears in its own block, with its source and date. It is a modeled installed-cost range, not a quote, and its figures are not repeated here.
