GE GG30T**BXR01

The registry lists a UEF, the ratio of hot water delivered to energy used, of 0.6 for this unit. This site, not the registry, computed the 185 therms figure from that UEF and the DOE test's daily hot-water draw for the medium draw pattern. The source is DOE CCD, retrieved 2026-09-19. The figure counts natural gas only and holds under that test condition. Among the 288 models registered as a gas tank at the medium draw pattern, this unit ranks 89th lowest for energy use. That places it in the second-lowest quarter of its class, level with the median of 185 therms. The calculation is described in how the annual cost is calculated.

The first hour rating, the gallons of hot water available in the first hour from a full tank, is 62 gallons for this model, and its rated volume is 30 gallons. The medium draw pattern describes a typical household with a busy morning, so the 185 therms figure suits a household whose use resembles that. It does not describe a household with a much larger or smaller daily draw. Energy use at other draw patterns is not available for this model on this page and is not estimated here. A difference of 0 therms from the class median says nothing about whether the tank meets a household's peak demand. To compare units by fuel, space and size, use the water heater selector.

Running cost is not written as a figure here because it depends on the state average residential gas price, which differs between readers. Multiplying 185 therms by your own rate gives the yearly gas cost at the medium draw pattern, and the cost calculator does this from your ZIP. The installed price range for this model is not published. Its ratings of 0.6 UEF, 62 gallons first hour rating and 30 gallons rated volume lie outside the range the cost database's model was fitted on, and that range is not stretched past it.
