GE GG30S**BXR01

The 185 therms figure is computed by this site, not the registry. It uses the registry's UEF, the ratio of hot water delivered to energy used, which is 0.6 for this model, together with the DOE test's daily hot-water draw for the medium draw pattern. The figure therefore holds only at that test draw. A household that uses more or less hot water than the test draw will use a different amount, and that amount is not available here. The source is DOE CCD, retrieved 2026-09-19. The calculation steps are set out in how the annual cost is calculated.

Among the 288 models registered as a gas tank at the medium draw pattern, this one has the 89th lowest energy use of 288. That places it in the quarter of the class just above the lowest-energy quarter. Its 185 therms equals the class median of 185 therms, so the difference is 0 therms. The rating suits a typical multi-person household whose use resembles the test draw. Its first hour rating, the gallons of hot water available in the first hour from a full tank, is 64 gallons, and its rated volume is 30 gallons. A household whose busiest hour needs more than 64 gallons falls outside what this rating covers. To compare other units, use the selector by fuel, space and size.

The running cost is not written here because it depends on your state's average residential gas price. Multiply the 185 therms by your own rate, or let the cost calculator on your own ZIP do it. The result is valid only for the medium draw pattern. An installed price range for the GG30S**BXR01 is not published: its ratings lie outside the range the cost database's model was fitted on, and the range is not stretched past it. If you need a unit in the same class, you can find a same-class replacement by model number.
