Rheem PROG40-40N RH67 PV

0.7 UEF DOE CCD · 2026-09-19
E

Grade E: 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).

You are checking the registry figures for the Rheem PROG40-40N RH67 PV, a gas tank water heater. It uses 242 therms of natural gas a year at the high draw pattern, the standard daily hot-water usage DOE tests against. That is 18 therms below the 260 therms median for the 414 gas tank models at that pattern.


Energy use per year

242 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 260 therms for the 414 models registered in the same heater type and draw pattern; it ranks 90 of 414, lowest energy first.

This model: 242 therms

Solid line: this model (242 therms). Dashed line: the class median.

What these figures mean

This site calculated the 242 therms figure. 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 0.7. The inputs come from DOE's Compliance Certification Database (CCD), retrieved 2026-09-19. The figure applies only at that test draw. A household that draws more or less hot water will use a different amount of gas. Among the 414 gas tank models registered at the high draw pattern, this unit ranks 90th lowest for energy use. That puts it in the lowest quarter of its class. The method page explains how the annual cost is calculated from these inputs.

The high draw pattern represents a larger household, or one where showers and laundry overlap. The registry lists a first hour rating, the gallons of hot water available in the first hour from a full tank, of 79 gallons for this model. Its rated volume is 38 gallons. A household whose busiest hour stays within 79 gallons matches the conditions behind the 242 therms figure. A household with lighter daily use is closer to a different draw pattern, so the 242 therms figure does not describe it. A household that needs more than 79 gallons in its busiest hour falls outside what this rating covers. To compare other models by fuel, space and size, use the water heater selector.

The text on this page does not give a running cost. The cost depends on your state's average residential natural gas price. The page calculates it from your ZIP in the cost calculator for your own ZIP. The text can state the gas use: 242 therms a year at the high draw pattern, 18 therms below the class median of 260 therms. That 18 therms gap turns into a cost difference at whatever gas rate applies where you live. The installed-cost range appears in its own block, with its own source and date. It is a modeled range, not a quote. If you are matching this unit, the same-class replacement search by model number lists models in this class.
