Rheem PROG29-32N RH63 *
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).
This site computes 185 therms of natural gas a year for the Rheem PROG29-32N RH63 * gas tank. That figure uses the medium draw pattern, the standard daily hot-water usage DOE tests against. It equals the class median of 185 therms, a difference of 0 therms, among 288 models.
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 annual figure is 185 therms of natural gas, computed by this site rather than the registry. The registry lists a UEF, the ratio of hot water delivered to energy used, of 0.6. The site pairs it with the fixed daily hot-water draw that the DOE test uses for the medium draw pattern. The source is the DOE CCD, retrieved 2026-09-19. Its rank is 89th lowest energy use of 288 gas tank models, in the second-lowest quarter of its class. The figure equals the class median of 185 therms, so the difference is 0 therms.
Its first hour rating, the gallons of hot water available in the first hour from a full tank, is 63 gallons. Its rated volume is 28 gallons. A household that uses more hot water on its busiest morning than 63 gallons may run short. The annual energy figure does not measure that. The figure suits a reader who is checking a quoted number for this model at the medium draw pattern. It suits a household with a much larger or smaller daily draw less well, because energy use there would differ from 185 therms. The water heater selector compares models by fuel, space and size.
The running cost is not written here, because it depends on your state's average residential gas price. Applying that price to the 185 therms gives the yearly cost at the medium draw pattern. This page cannot state a running cost for the Rheem PROG29-32N RH63 * without that price. The cost calculator does this from your own ZIP. The annual cost method is described separately. 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. To find a same-class replacement, search by model number.
