GE GG50S**AYV01

This site computed the 182 therms figure, not the registry. It combines the registry's UEF with the DOE test's daily hot-water draw for the medium draw pattern. UEF, the ratio of hot water delivered to energy used, is 0.61 for this model. The data come from DOE CCD, retrieved 2026-09-19. The comparison group is the 288 models registered as a gas tank at the medium draw pattern. Their median is 185 therms, so this model sits 3 therms below it. Its rank is 73rd lowest energy use of 288, which places it in the second-lowest quarter of its class. The figure holds only for the medium draw pattern. Other usage would change it, and this page does not estimate that.

The first hour rating, the gallons of hot water available in the first hour from a full tank, is 73 gallons for this model. Its rated volume is 50 gallons. The medium draw pattern describes a busy morning in a typical three- or four-person household, and the 182 therms figure describes that case. A household with much higher use falls outside the test condition, and the registry data used here do not show how this model would perform then. Because the difference from the class median is only 3 therms, energy use alone does not place this model far from the middle of its class. To compare on fuel, space and size, the water heater selector narrows the field.

No running cost is written in this text. It depends on the state average residential gas price, which differs by reader. The cost calculator applies the price for your ZIP to the 182 therms of natural gas, and the methodology page explains how the annual cost is calculated. Any cost you get is tied to natural gas and to the medium draw pattern. The installed price range for GG50S**AYV01 is shown in its own block with its source and date, as a modeled range and not a quote.
