The 182 therms figure is not stated by the registry itself. This site computed it from the registry's UEF, the ratio of hot water delivered to energy used, which is 0.61 for this model. The calculation uses the DOE test's daily hot-water draw for the medium draw pattern. The source is DOE CCD, retrieved 2026-09-19. The figure applies only to that test draw and to natural gas. A home with a different draw will use a different amount, and this data does not say how much.

Among the 288 models registered as a gas tank at the medium draw pattern, this unit ranks 73rd lowest for energy use. That places it in the second-lowest quarter of its class. The difference from the class median of 185 therms is 3 therms, and no other comparison is given. The tank holds 50 gallons. Its first hour rating, the gallons of hot water available in the first hour from a full tank, is 65 gallons. Households whose demand matches the medium draw pattern can compare these figures directly. To check other sizes or fuels, use the water heater selector by fuel, space and size.

The running cost is not stated in the text, because it depends on the state average residential gas price. The cost calculator on your own ZIP applies 182 therms to your local rate. The methodology page explains how the annual cost is calculated. Any model in the class is priced at the same gas rate, so the 3 therms gap to the median converts to cost at that rate. The installed price range appears in its own block with its source and date. It is a modeled range, not a quote. The energy figure describes a test draw, not a measurement of any single home.
