JETGLAS URG2PDV50TH*N

This site calculates the 245 therms figure; the registry does not publish it. It combines the registry's UEF, the ratio of hot water delivered to energy used, with the DOE test's daily hot-water draw for the high pattern. This model's UEF is 0.69, as listed in the DOE Compliance Certification Database, retrieved 2026-09-19. The result holds only at the federal test's draw. A home that uses more or less hot water than the test will use a different amount of gas. That amount is not available here. The 15 therms gap noted above places this model in the second-lowest quarter of its class for energy use. The median is the middle value of the 414 registered models, not an average.

The high draw pattern stands for a larger household, or one where showers and laundry overlap. The registry lists its first hour rating, the gallons of hot water available in the first hour from a full tank, as 109 gallons. Its rated volume is 46 gallons. A plumber or seller checking a match can compare those two figures with the unit it replaces. The same-class replacement finder by model number lists other gas tank models at the high pattern. This page has no energy figure for a household with a smaller daily draw. The 245 therms value does not describe that case. The water heater selector by fuel, space and size covers other sizes and fuels.

This text does not state the running cost because it depends on your state's average residential gas price. The page works it out from your ZIP in its own block, using the 245 therms figure at the high draw pattern. The cost calculator on your own ZIP repeats that calculation at other rates. The 15 therms yearly gap to the class median also becomes a cost only at your rate. This page gives no fixed amount for it. The steps behind the figure are set out in how the annual cost is calculated. The installed price range appears in a separate block with its own source and date. It is a modeled installed-cost range, not a quote.
