BRADFORD WHITE RG2D40S*N
0.64 UEF DOE CCD · 2026-09-19Grade E: 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 checking the BRADFORD WHITE RG2D40S*N, it uses 173 therms of natural gas a year. That figure is at the medium draw pattern, the standard daily hot-water usage DOE tests against. It sits 12 therms below the 185 therms median of the 288 gas tank models in its class, ranking 44th lowest.
Energy use per year
173 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 44 of 288, lowest energy first.
Solid line: this model (173 therms). Dashed line: the class median.

This site computed the 173 therms figure. The registry does not publish it. Its UEF, the ratio of hot water delivered to energy used, is 0.64. This site combines that value with the DOE test's daily hot-water draw for the medium pattern. The UEF comes from the DOE Compliance Certification Database (CCD), retrieved 2026-09-19. The result describes use at the test's fixed daily draw, not in any particular home. A household that draws more hot water each day will use more gas than 173 therms, and one that draws less will use less. The steps behind the number are set out in how this site calculates annual energy and cost. This is a model-level figure. It does not reflect the condition or settings of an installed unit.
The RG2D40S*N has a rated volume of 38 gallons. Its first hour rating, the gallons of hot water available in the first hour from a full tank, is 62 gallons. A household whose busiest hour needs no more than 62 gallons is within this rating. A household whose peak hour needs more than 62 gallons is outside it. The medium-pattern energy figure does not describe that household's use. For energy use, the model ranks 44th lowest of 288 in its class, which places it in the lowest quarter. To compare it with other units, use the water heater selector by fuel, space and size. To check a same-class swap, find a replacement by model number.
The text on this page does not state a running cost for the RG2D40S*N. The cost of 173 therms of natural gas depends on your state's average residential gas price. For that reason, the page computes it from your ZIP. You can run that figure in the water heater cost calculator for your ZIP. The same rate applies to the 12 therms gap between this model and the 185 therms class median. That gap is a difference in gas use, and its value in money also depends on your rate. The installed price range appears in its own block, with its source and date. It is a modeled installed-cost range, not a quote, and this text does not restate it. Figures for your own home beyond these are not available here.
