STATE GDVNT-50L 1**

This site calculated the 260 therms figure; the registry does not publish it. 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 high draw pattern. For the GDVNT-50L 1**, the UEF is 0.65. The registry data come from DOE CCD, retrieved 2026-09-19. The figure holds only at that test draw. A household that uses more or less hot water than the test assumes will use a different amount of gas. This page has no figure for that case. The full steps are set out in how the annual cost is calculated.

The high draw pattern stands for a larger household, or one where showers and laundry overlap. The GDVNT-50L 1** has a first hour rating, the gallons of hot water available in the first hour from a full tank, of 84 gallons. Its rated volume is 48 gallons. It is compared with the 414 models registered as a gas tank at the high draw pattern. At 260 therms, it sits in the second-lowest quarter of that class for energy use. Its difference from the class median is 0 therms, so on this measure it is neither above nor below the median. A plumber checking a swap can find a same-class replacement by model number.

The running cost is not stated in this text. It depends on your state's average residential gas price, so the page computes it from your ZIP. At the same 260 therms, readers in different states can see different yearly costs. The installed price appears in its own block with its source and date. It is a modeled range, not a quote. If your household does not match the high draw pattern, this page cannot say how much gas the GDVNT-50L 1** would use. That figure is not available here.
