GSW WATER HEATERS GPVX-50L 2**
0.73 UEF DOE CCD · 2026-09-19Grade 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 GSW WATER HEATERS GPVX-50L 2**, here is its registry-based energy figure. This gas tank uses 232 therms of natural gas a year at the high draw pattern, the standard daily hot-water usage DOE tests against. That is 28 therms below the 260 therms median of the 414 gas tank models registered at that draw pattern.
Energy use per year
232 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 33 of 414, lowest energy first.
Solid line: this model (232 therms). Dashed line: the class median.

The 232 therms figure does not appear in the registry itself. This site computed it from the model's UEF, the ratio of hot water delivered to energy used, and the DOE test's daily hot-water draw for the high draw pattern. The registry lists this model's UEF as 0.73. The source is the DOE Compliance Certification Database, retrieved 2026-09-19. The figure holds only at the federal test's daily draw, so it is a comparison value rather than a meter reading. It does not describe a household whose daily hot-water use differs from the test draw. The steps that turn UEF and draw into a yearly figure are set out in how the annual cost is calculated.
The high draw pattern stands for a larger household, or one where showers and laundry overlap. Among the 414 gas tank models registered at that pattern, this model ranks 33rd lowest for energy use. Its first hour rating, the gallons of hot water available in the first hour from a full tank, is 119 gallons from a 50-gallon tank. The registry places the model in the high pattern, and its energy figure belongs to that pattern alone. For a smaller household with lighter daily use, the 232 therms figure does not apply. A figure at a lower draw pattern is not available for this model. A plumber or seller confirming a swap can find a same-class replacement by model number and compare it with models tested at the same pattern.
This text gives no running cost, because the cost depends on the reader's state average residential gas price. The page computes it from your ZIP by applying that price to the 232 therms yearly use at the high draw pattern. Enter your ZIP in the cost calculator on your own ZIP to see the cost for your state. At the same gas price, the 28 therms gap below the class median of 260 therms means a lower yearly cost than the median model. The size of that difference depends on the price and is not stated here. Actual bills for a specific home are unknown to this site. The installed price range appears in its own block, with its source and date. It is a modeled range, not a quote.
