U.S. CRAFTMASTER GCRT-50 4**

0.61 UEF DOE CCD · 2026-09-19
G

Grade G: 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 U.S. CRAFTMASTER GCRT-50 4**, a gas tank water heater, here is its rated energy use. It uses 277 therms of natural gas a year at the high draw pattern, the standard daily hot-water usage DOE tests against. That is 17 therms above the 260 therms median for the 414 models in its class.


Energy use per year

277 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 260 therms for the 414 models registered in the same heater type and draw pattern; it ranks 400 of 414, lowest energy first.

This model: 277 therms

Solid line: this model (277 therms). Dashed line: the class median.

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 277 therms figure is computed by this site, not published by the registry. It combines the registry's UEF, the ratio of hot water delivered to energy used, with the DOE test's daily hot-water draw for the high draw pattern. This model's UEF is 0.61, taken from DOE CCD data retrieved 2026-09-19. The figure applies only at that test draw; actual use in a given home is not available here. Among the 414 models registered as a gas tank at the high draw pattern, it ranks 400th lowest in energy use. That places it in the highest quarter of its class for energy use. Each step is set out in how this site calculates annual energy and cost.

The high draw pattern stands for a larger household, or one where showers and laundry overlap. This model lists a first hour rating, the gallons of hot water available in the first hour from a full tank, of 89 gallons. Its rated volume is 48 gallons. For a household with that kind of demand, these are the figures to check against the registry listing. For a smaller household with lower demand, the 277 therms figure does not describe its use, because the test draw would not match. Whether another model would suit such a home is not assessed here. To find a unit in the same class by model number, use the same-class replacement search.

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 code. The input is the same 277 therms at the high draw pattern. This model sits 17 therms above its class median of 260 therms. At any single gas rate, its yearly gas cost is therefore above that of a model at the class median. How far above depends on your rate, which is not known here. The installed price range appears in its own block on this page, with its source and date; it is a modeled range, not a quote. To see the yearly figure for your area, use the running cost calculator for your ZIP.
