BRADFORD WHITE RG230S*N
0.54 UEF DOE CCD · 2026-09-19Grade G: where this UEF sits among the 9 models in its class, lowest (G) to highest (A). A position, not an official label. How the grade is set
A gas tank, low draw pattern (a one- or two-person household).
If you are checking BRADFORD WHITE RG230S*N against registry data, this page answers at model level. It uses 142 therms for natural gas at the low draw pattern, the standard daily hot-water usage DOE tests against. In its gas tank, low draw class, that equals the 142 therms median.
Energy use per year
142 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 equal to the median of 142 therms for the 9 models registered in the same heater type and draw pattern; it ranks 4 of 9, lowest energy first.
Solid line: this model (142 therms). Dashed line: the class median.

What it costs to install
Not published: Installed cost range
This model's UEF 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 energy figure is computed by this site from the registry UEF, the ratio of hot water delivered to energy used, and the DOE test draw for this model's draw pattern. DOE CCD data retrieved 2026-09-19 gives the registry basis, but the annual therm figure is not copied from the registry. For BRADFORD WHITE RG230S*N, 142 therms applies only at the low draw pattern and the federal test's daily hot-water draw. The model's UEF is 0.54 for this registry record. The method behind that conversion is described in how annual cost is calculated.
Within the registered comparison class, this model is compared with the 9 models listed as a gas tank at the low draw pattern. Its 142 therms is 0 therms from the 142 therms class median, so the registry-based result is equal to the middle value for this class. Its rank is 4th lowest energy use of 9 under that same class definition. The page therefore treats it as in the second-lowest quarter of its class for energy use, not as a broader judgment. To compare similar records by model identity, use find a same-class replacement by model number.
Capacity context is separate from annual energy. The first hour rating, the gallons of hot water available in the first hour from a full tank, is 49 for this model. Rated volume is 29 for this gas tank record. Running cost is not stated in the text, because it depends on the reader's state average residential gas price from ZIP. The ZIP-based figure belongs in the cost calculator on the reader's own ZIP. An installed price range is also not available, because this model's ratings fall outside the fitted range used by the cost database.
