0.7 UEF DOE CCD · 2026-09-19Grade 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).
This unit 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 class median of 260 therms. It ranks 90th lowest of 414 gas tank models registered at this draw 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.
Solid line: this model (242 therms). Dashed line: the class median.

The figure of 242 therms is computed by this site, not published by the registry. It comes from the registry's UEF and the daily hot-water draw that the DOE test uses for this draw pattern. UEF, the ratio of hot water delivered to energy used, is 0.7 for this model. The source is DOE CCD, retrieved 2026-09-19. The value holds only at the federal test's draw, and the fuel is natural gas. Real gas use in a home can differ from it, and this page has no measured field data for the model. The methodology page explains how the annual cost is calculated.
The high draw pattern stands for a larger household, or one where showers and laundry overlap. The model's first hour rating, the gallons of hot water available in the first hour from a full tank, is 75 gallons. Its rated volume is 38 gallons. The energy comparison suits a household that matches that pattern, because the class of 414 models was registered at the same draw. A household with much lower use is not described by 242 therms at the high draw pattern, and this page cannot say by how much. The water heater selector filters by fuel, space and size.
Running cost is not stated in the text. It depends on your state's average residential gas price, which this page does not assume. The cost calculator applies that price to 242 therms from your ZIP code. The same price applies to the gap of 18 therms from the class median. Its rank of 90th lowest of 414 places it in the lowest quarter of its class for energy use, at the high draw pattern only. To compare a same-class alternative, find a replacement by model number. The installed price range is in its own block on the page, as a modeled range and not a quote.
