LOCHINVAR GURT-50RL 4**

The registry does not print the 269 therms figure. This site computed it from the model's UEF, the ratio of hot water delivered to energy used, and the DOE test's daily hot-water draw for the high draw pattern. The UEF input is 0.63, taken from the DOE Compliance Certification Database (CCD), retrieved 2026-09-19. The result therefore holds only at that test draw. A household that uses more or less hot water than the test assumes will burn a different amount of gas. This page has no data on any real household's use, so that amount is unknown here. The steps behind the figure are set out in how the annual cost is calculated.

The high draw pattern describes a larger household, or one where showers and laundry overlap. For that use, the registry lists a first hour rating, the gallons of hot water available in the first hour from a full tank, of 92 gallons. The rated volume is 49 gallons. The class comparison covers only the 414 models registered as a gas tank at the same draw pattern. The 9 therms gap above the median, noted in the summary, means more than half of that class uses less gas at the test draw. A reader whose main check is gas use can compare units in the same class through a same-class replacement search by model number.

This text does not state the running cost. It depends on the average residential natural gas price in the reader's state, which this page does not assume. The page computes the cost from the reader's ZIP, applying that price to the 269 therms test-draw figure. At any single gas price, the 9 therms gap to the class median carries into the cost in the same proportion. The installed price range appears in its own block, with its source and date. It is a modeled installed-cost range, not a quote. To run the figure for a location, use the cost calculator on your own ZIP.
