STATE GPDNT-50 1**
0.7 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 STATE GPDNT-50 1** gas tank water heater, it uses 242 therms of natural gas a year. That figure applies at the high draw pattern, the standard daily hot-water usage DOE tests against. It sits 18 therms below its class median of 260 therms, ranking 90th lowest of 414 models.
Energy use per year
242 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 90 of 414, lowest energy first.
Solid line: this model (242 therms). Dashed line: the class median.

This site computed the 242 therms figure; the registry does not publish it. The calculation 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 0.7. The source is the DOE Compliance Certification Database (CCD), retrieved 2026-09-19. The comparison group is the 414 models registered as a gas tank at the high draw pattern, and their median is 260 therms a year. At 18 therms below that median, this unit is in the lowest quarter of its class for energy use. Your household's daily hot-water draw will differ from the test draw. For that reason, your actual gas use is not available here. The method is set out in how the annual cost is calculated.
The high draw pattern represents 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 75 gallons. Its rated volume is 48 gallons. If your household uses more than 75 gallons in its busiest hour, it draws more than this rating covers. If your household is smaller, the 242 therms figure does not describe its use, because that figure applies only at the high draw pattern. This page does not include energy use for any other draw pattern. The selector by fuel, space and size filters units by those three criteria.
This text does not state the running cost, because it depends on your state's average residential gas price. The page applies the price for your ZIP to the 242 therms a year at the high draw pattern. To see that result, enter your ZIP in the cost calculator on your own ZIP. This unit uses 18 therms less gas than the class median at the test draw. So at any single gas price, its cost is lower than the cost of a unit at the median. The installed price range has its own block, with its source and date. That range is modeled; it is not a quote. To match this unit with another gas tank model at the high draw pattern, use find a same-class replacement by model number.
