AMERICAN GCR-30R 2**

The 182 therms figure is not a registry entry. This site computed it from the registry's UEF, the ratio of hot water delivered to energy used, and the DOE test's daily hot-water draw for the medium draw pattern. The UEF listed for this model is 0.61. The registry also gives a first hour rating, the gallons of hot water available in the first hour from a full tank, of 52 gallons, and a rated volume of 29 gallons. The energy value applies to natural gas at that test draw only. Actual use in a home depends on how much hot water the household draws. The source is DOE CCD, retrieved 2026-09-19, and the steps are set out on the methodology page.

Within its class, this model has the 73rd lowest energy use of 288 gas tank models registered at the medium draw pattern. That places it in the second-lowest quarter of the class. Its 182 therms is 3 therms below the class median of 185 therms. The comparison suits a household whose hot-water use resembles the medium draw pattern and who wants to check this model against its registered peers. It does not suit a household whose use differs from that draw, because the figure would change with it. It also does not cover other fuels or other draw patterns. To narrow models by fuel, space and size, the water heater selector is available.

The running cost is not written here, because it depends on your state's average residential gas price. The cost calculator takes your ZIP and applies that price to the 182 therms at the medium draw pattern. The installed price range is not published for this model. Its ratings, a UEF of 0.61 and a first hour rating of 52 gallons, lie outside the range the cost database's model was fitted on, and the range is not stretched past it.
