STATE GDV-40 3**
0.6 UEF DOE CCD · 2026-09-19Grade F: 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 the STATE GDV-40 3**, a gas tank water heater, this site calculates its use at 185 therms of natural gas a year. That figure holds at the medium draw pattern, the standard daily hot-water usage DOE tests against. It is equal to the median of the 288 gas tank models registered at that pattern.
Energy use per year
185 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 equal to the median of 185 therms for the 288 models registered in the same heater type and draw pattern; it ranks 89 of 288, lowest energy first.
Solid line: this model (185 therms). Dashed line: the class median.

The 185 therms figure comes from this site's calculation, not from the registry. It 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 medium pattern. For this model, the UEF is 0.6. The underlying record is from the DOE CCD, retrieved 2026-09-19. The calculation steps are set out in how the annual cost is calculated. The figure applies only at the test's daily draw. This page cannot state the gas use for a home that draws more or less hot water than the test does.
Among the 288 models registered as a gas tank at the medium draw pattern, the median is 185 therms. This model differs from that median by 0 therms, and it ranks 89th lowest in energy use of 288. Its rated volume is 39 gallons. Its first hour rating, the gallons of hot water available in the first hour from a full tank, is 64 gallons. A household whose busiest hour stays within 64 gallons falls inside what that rating covers. A household that regularly needs more in its busiest hour falls outside it. To compare other units by fuel, space and size, see the water heater selector by fuel, space and size.
The page text states no running cost. That cost equals 185 therms times your state's average residential natural gas price, so it differs by state. The page computes it from your ZIP. You can repeat the calculation with the cost calculator on your own ZIP. Because this model uses 0 therms more or less than the class median of 185 therms, at any given gas price its cost matches a median model in the class. The installed price range sits in its own block with its source and date. It is a modeled range, not a quote.
