E

Grade 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).

If you are checking the Ruud XG29T12XR60U0, this gas tank heater uses 238 therms of natural gas a year. That figure belongs to the high draw pattern, the standard daily hot-water usage DOE tests against. It sits 22 therms below the class median of 260 therms, ranking 84th lowest of 414 models.


Energy use per year

238 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 84 of 414, lowest energy first.

This model: 238 therms

Solid line: this model (238 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.

What these figures mean

The 238 therms figure is computed by this site, not taken from the registry. It combines two inputs: the model's UEF, the ratio of hot water delivered to energy used, and the DOE test's daily hot-water draw. This model's UEF is 0.71, and the draw used is the one set for the high draw pattern. The UEF comes from the DOE CCD, retrieved 2026-09-19. The yearly figure therefore holds only at the federal test's daily draw. A household drawing more or less hot water will use a different amount of gas. How large that difference is for any given home is not available from the registry data. The steps behind the figure are set out on the page explaining how the annual cost is calculated.

The high draw pattern describes a larger household, or one where showers and laundry overlap. This model's first hour rating, the gallons of hot water available in the first hour from a full tank, is 93 gallons. Its rated volume is 28 gallons. A home whose busiest hour needs more than 93 gallons of hot water is outside what this rating covers. The yearly figure is for natural gas, so it does not apply to a home without a gas supply. Among the 414 models registered as a gas tank at the high draw pattern, this unit ranks 84th lowest in energy use. That 22 therms gap below the 260 therms median is measured at the test draw only. To compare units by fuel, space and size, use the water heater selector.

The running cost is not stated in this text. It depends on your state's average residential gas price, so the page computes it from your ZIP. That calculation applies your rate to the 238 therms yearly figure at the high draw pattern. You can rerun it with the cost calculator for your own ZIP. The 22 therms difference from the class median becomes a cost difference only at your own rate, and it is not converted here. 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 page does not stretch that range to cover this unit, so its installed price is unknown here.
