Rheem XG29T06EC32U1 *
0.6 UEF DOE CCD · 2026-09-19Grade F: 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 Rheem XG29T06EC32U1 * gas tank water heater, here is its yearly energy use. It uses 185 therms of natural gas a year at the medium draw pattern, the standard daily hot-water usage DOE tests against. That equals the class median of 185 therms among 288 comparable gas tank models, a difference of 0 therms.
Energy use per year
185 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 185 therms for the 288 models registered in the same heater type and draw pattern; it ranks 89 of 288, lowest energy first.
Solid line: this model (185 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.

UEF 0.6 · Grade F Price it on your ZIP
The registry does not print the 185 therms figure. This site calculated it from the model's UEF, the ratio of hot water delivered to energy used. That ratio is 0.6 for this model. The calculation also uses the daily hot-water draw from the DOE test for the medium draw pattern. DOE describes that pattern as a typical household with a busy morning. The registry values come from the DOE CCD, retrieved 2026-09-19. If your household uses more hot water than that test day, your yearly gas use will be higher than 185 therms. If it uses less, your gas use will be lower. The page on how the annual energy and cost figures are calculated lists each input and where it comes from.
This unit is compared with the 288 models registered as a gas tank at the medium draw pattern. It ranks 89th lowest in energy use among them. Its 185 therms equals the class median of 185 therms, a difference of 0 therms. The fit for a home also depends on capacity, which is a separate question. The tank holds 28 gallons. Its first hour rating, the gallons of hot water available in the first hour from a full tank, is 62 gallons. That rating covers a household whose busiest hour stays within 62 gallons. It does not cover a household that needs more in that hour, whatever the yearly energy figure shows. To see other models in the same class, use the same-class replacement search by model number.
The text on this page gives no running cost. The cost of 185 therms of natural gas depends on your state's average residential gas price. For that reason, the page calculates the cost from your ZIP code and does not print one fixed figure. You can also enter the same 185 therms in the water heater cost calculator for your ZIP code. Any cost you get this way applies only to the test-day usage of the medium draw pattern. An installed price range is not available for this model. Its ratings, including the UEF of 0.6 and the first hour rating of 62 gallons, fall outside the range the cost database's model was fitted on. The site does not extend that range to cover this model, so its installed price is not known here.
