STATE GDV-50 3**

0.66 UEF DOE CCD · 2026-09-19
F

Grade F: 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 STATE GDV-50 3**, this gas tank water heater uses 256 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 4 therms below the 260 therms median of the 414 gas tank models registered at that draw pattern.


Energy use per year

256 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 192 of 414, lowest energy first.

This model: 256 therms

Solid line: this model (256 therms). Dashed line: the class median.

What these figures mean

The 256 therms figure was computed by this site, not taken from the registry. It starts from the registry's UEF, the ratio of hot water delivered to energy used, which is 0.66 for this model. That ratio is applied to the DOE test's daily hot-water draw for the high draw pattern. The source is the DOE Compliance Certification Database, retrieved 2026-09-19. The figure holds only at that test draw. A home that uses more or less hot water will use a different amount of gas. Against the 260 therms class median, this model ranks 192nd lowest in energy use of 414. To see how the energy figure becomes a yearly cost, read how the annual cost is calculated.

The high draw pattern describes a larger household, or one where showers and laundry overlap. The 256 therms figure applies to a home with that level of use. This model lists a first hour rating, the gallons of hot water available in the first hour from a full tank, of 77 gallons. Its rated volume is 48 gallons. These are registry values for GDV-50 3**, not measurements from any installed unit. This page does not cover homes with lighter daily use than the test assumes. The gas use of this model at a lower draw is not available here. To compare other units by fuel, space and size, use the water heater selector.

The text on this page does not state a running cost. The cost of 256 therms of natural gas a year depends on your state's average residential gas price. The page computes that cost from your ZIP code. Enter your ZIP in the cost calculator for your own ZIP code to see the figure at your rate. The installed price range has its own block on this page, with its source and date. It is a modeled installed-cost range, not a quote. If you need another unit in the same class as the STATE GDV-50 3**, you can find a same-class replacement by model number.
