BRADFORD WHITE RG2MH40T*N
0.59 UEF DOE CCD · 2026-09-19Grade G: 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 this unit against the registry, the BRADFORD WHITE RG2MH40T*N uses 188 therms of natural gas a year at the medium draw pattern. That is 3 therms above the class median of 185 therms. It ranks 186th lowest in energy use among 288 gas tank models.
Energy use per year
188 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 185 therms for the 288 models registered in the same heater type and draw pattern; it ranks 186 of 288, lowest energy first.
Solid line: this model (188 therms). Dashed line: the class median.

What it costs to install
Not published: Installed cost range
This model's rated tank size lies outside the range NLR REMDB's cost model was fitted on, and the range is not stretched past it.
The annual energy figure on this page does not depend on this range and is unaffected.
Safety record
No CPSC recall names this model.
Checked against the CPSC recall database. CPSC does not publish a model-level match for this product category, so this list is curated by hand from the manufacturer's recall filings.

The annual figure of 188 therms of natural gas is computed by this site, not by the registry. It uses the registry's UEF, the ratio of hot water delivered to energy used, which is 0.59 for this model. It also uses the daily hot-water draw that the DOE test sets for its draw pattern, the standard daily hot-water usage DOE tests against. The pattern here is medium, which stands for a typical household on a busy morning. The source is DOE CCD, retrieved 2026-09-19. The result holds only at the test's draw. Actual use in a home differs with the hot water that home draws. The calculation is set out in how the annual cost is calculated.
The class holds 288 models registered as a gas tank at the medium draw pattern. This unit sits 3 therms above the class median of 185 therms. Its rank is 186th lowest of 288, in the higher-use part of the class but not among its highest-use quarter. Rank here reflects energy use at the test draw only. It does not measure how much hot water the unit supplies. The first hour rating, the gallons of hot water available in the first hour from a full tank, is 54 for this model. The rated volume is 37 gallons. A household with morning demand above the medium pattern should compare these ratings with its own use. The water heater selector by fuel, space and size filters by those inputs.
Running cost is not stated here because it depends on your state's average residential gas price. Multiply 188 therms by that price per therm to get the cost at the medium draw pattern. The cost calculator on your own ZIP does this for you. The figure suits a check for a household whose use resembles the medium draw pattern. It fits less well where daily hot-water use is far from the test's draw, because gas use follows the hot water drawn. An installed price range is not published for this model. Its ratings lie outside the range the cost database's model was fitted on. The range is not stretched past that limit.
