A. O. SMITH GPVNT-50 1**
0.72 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).
Checking this unit against the registry? The A. O. SMITH GPVNT-50 1** uses 235 therms of natural gas a year. That figure belongs to the high draw pattern, the standard daily hot-water usage DOE tests against. It is 25 therms below the class median of 260 therms, ranking 50th lowest of 414.
Energy use per year
235 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 50 of 414, lowest energy first.
Solid line: this model (235 therms). Dashed line: the class median.

The registry lists a UEF, the ratio of hot water delivered to energy used, of 0.72 for this model. This site combines that UEF with the DOE test's daily hot-water draw for the high draw pattern. The result is 235 therms of natural gas a year. The registry does not publish this figure, so the site computes it. The source is DOE CCD, retrieved 2026-09-19. The figure describes the test's draw, not any single household. A home with a different daily draw would use a different amount, and that amount is not available in this data. The method is described on the page about how the annual cost is calculated.
The high draw pattern fits a larger household, or one where showers and laundry overlap. The first hour rating, the gallons of hot water available in the first hour from a full tank, is 85 gallons here. The rated volume is 48 gallons. The registry lists both values. A household that needs more than 85 gallons in its busiest hour would exceed this rating. Households with a lower daily draw are not covered by the high draw pattern figure, and their annual energy use is not available here. Someone comparing fuel, space or size can use the water heater selector. This page does not judge whether the model suits a particular home.
The running cost is not stated here. It depends on your state's average residential gas price, and this page holds no value for it. Multiply your own rate by 235 therms to get the yearly gas cost at the high draw pattern. The cost calculator on your own ZIP does this for you. The gap of 25 therms below the class median of 260 therms is a difference in energy, and its cost effect depends on your rate. It places the model in the lowest quarter of its class, at 50th lowest of 414. To compare it with another unit in the same class, you can find a same-class replacement by model number.
