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 this gas tank model, it uses 269 therms of natural gas a year. That figure applies to the high draw pattern, the standard daily hot-water usage DOE tests against, for a larger household. It sits 9 therms above the class median of 260 therms, among 414 comparable models.
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.

UEF 0.63 · Grade G Price it on your ZIP
The figure of 269 therms was 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. The registry lists a UEF of 0.63 for this model. The condition is the high draw pattern, and the fuel is natural gas. The daily draw is the one DOE assigns to that pattern. The source is DOE CCD, retrieved 2026-09-19. The figure does not describe any single home, because real hot-water use varies. It allows comparison between models tested the same way, and it does not measure your household.
Registered as a gas tank at the high draw pattern, it has the 320th lowest energy use of 414 models. That places it in the highest quarter of its class for energy use. Its 269 therms is 9 therms above the class median of 260 therms. In this comparison the direction is above the median, not below it. The first hour rating, the gallons of hot water available in the first hour from a full tank, is 76 gallons. The rated volume is 48 gallons. These ratings suit the situation the high draw pattern describes: a larger household, or one where showers and laundry overlap. For a reader who ranks units by energy use alone, the class position above is the relevant figure.
The running cost is not stated in the text. It depends on the state average residential gas price, so the cost calculator computes it from your ZIP. The calculation applies that price to 269 therms. A different rate changes the cost in proportion, while the therms stay the same. The method for the annual cost is documented separately. The modeled installed-cost range is shown in its own block with its source and date. For a same-class comparison, find a replacement by model number and check its therms against the class median of 260 therms. Data on maintenance or repair cost is not available on this page, and none is estimated.
