STATE GPDL-40 3**
0.68 UEF DOE CCD · 2026-09-19Grade C: where this UEF sits among the 288 models in its class, lowest (G) to highest (A). A position, not an official label. How the grade is set
A gas tank, medium draw pattern (a typical three- or four-person household, about 55 gallons on a busy morning).
If you are checking this STATE GPDL-40 3** gas tank water heater, it uses 163 therms of natural gas a year. That figure applies to the medium draw pattern, the standard daily hot-water usage DOE tests against. It sits 22 therms below the 185 therms class median, ranking 5th lowest of 288.
Energy use per year
163 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 185 therms for the 288 models registered in the same heater type and draw pattern; it ranks 5 of 288, lowest energy first.
Solid line: this model (163 therms). Dashed line: the class median.

This site calculated the 163 therms figure; the registry does not publish it. The calculation uses the registry's UEF, the ratio of hot water delivered to energy used, which is 0.68 for this model. It also uses the DOE test's daily hot-water draw for the medium draw pattern. The registry data comes from the DOE Compliance Certification Database, retrieved 2026-09-19. Because the test fixes the daily draw, the figure describes this model only under that test condition. It does not describe gas use in any particular home. A household whose daily draw differs from the test will have a different annual figure, and this page does not have that figure. The steps behind the calculation are set out in how the annual energy and cost figures are calculated.
The registry lists a rated volume of 38 gallons for this model. It also lists a first hour rating, the gallons of hot water available in the first hour from a full tank, of 74 gallons. The medium draw pattern stands for a typical household's hot-water use, including a busy morning. The 163 therms figure applies to households whose use is close to that pattern. A household whose busiest hour needs more than 74 gallons needs more than this rating covers. The registry gives no energy figure for this model at any other draw pattern, so that figure is not available here. To compare this model with others by fuel, space or size, use the water heater selector by fuel, space and size.
This text does not give a running cost, because the cost depends on your state's average residential gas price. The page calculates it from your ZIP in a separate block, using the same 163 therms of natural gas a year. The 22 therms gap to the class median, given above, is also an amount of gas. What that gap costs depends on the same local rate. The installed price range on this page is a modeled range with its own source and date, not a quote. To price the annual use at your rate, open the cost calculator for your own ZIP. To find another unit in the same class, use the same-class replacement search by model number.
