AMERICAN GPVNT-50 1**

0.72 UEF DOE CCD · 2026-09-19
E

Grade 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 verifying the AMERICAN GPVNT-50 1**, a gas tank water heater, it 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 sits 25 therms below its 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.

This model: 235 therms

Solid line: this model (235 therms). Dashed line: the class median.

What these figures mean

The 235 therms figure is computed by this site, not published by the registry. It combines two inputs. One is the model's UEF, the ratio of hot water delivered to energy used, which is 0.72. The other is the DOE test's daily hot-water draw for the high draw pattern. The UEF comes from the DOE Compliance Certification Database, retrieved 2026-09-19. The comparison class holds the 414 models registered as a gas tank at the high draw pattern. Its median is 260 therms, and this model's gap of 25 therms below it places the model in the lowest quarter of its class for energy use. The figure holds only at the test's daily draw. An energy figure for a different daily draw is not available here. The steps are set out in how this site calculates annual energy and cost.

The high draw pattern describes a larger household, or one where showers and laundry overlap. For that use, the model lists a first hour rating, the gallons of hot water available in the first hour from a full tank, of 85 gallons. Its rated volume is 48 gallons. A home whose busiest hour needs more than 85 gallons falls outside what that rating covers. For a smaller household with lighter use, the 235 therms figure does not apply directly, because it rests on the high pattern's daily draw. This data does not give an energy figure for this model at a lighter draw pattern. Models with other fuels, sizes or installation spaces can be compared with the water heater selector by fuel, space and size.

This text does not state a running cost. The cost of 235 therms of natural gas depends on your state's average residential gas price. For that reason, the page computes it from your ZIP in a separate block. The same applies to the 25 therms gap from the class median: what that gap costs depends on your local rate. You can rerun the figure with the cost calculator for your own ZIP. The installed-cost range on this page is a modeled range, shown with its source and date, and it is not a quote. If you are checking a unit that will replace this one, you can find a same-class replacement by model number using GPVNT-50 1**.
