LOCHINVAR GCR-40 410
0.64 UEF DOE CCD · 2026-09-19Grade G: where this UEF sits among the 414 models in its class, lowest (G) to highest (A). A position, not an official label. How the grade is set
A gas tank, high draw pattern (a larger household, or one where showers and laundry overlap).
If you are verifying the LOCHINVAR GCR-40 410 gas tank heater, it uses 264 therms of natural gas a year. That figure applies at the high draw pattern, the standard daily hot-water usage DOE tests against. It sits 4 therms above the 260 therms median of the 414 gas tank models registered at that draw pattern.
Energy use per year
264 therms a year
Computed by this site from the registry's UEF and the federal test's daily hot-water draw for this draw pattern. What it costs depends on the natural gas rate where you live.
That is above the median of 260 therms for the 414 models registered in the same heater type and draw pattern; it ranks 236 of 414, lowest energy first.
Solid line: this model (264 therms). Dashed line: the class median.

The 264 therms figure is calculated by this site. 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 draw pattern. For this model the UEF is 0.64, taken from DOE CCD data retrieved 2026-09-19. So the result describes gas use at the test's daily draw, not in any particular home. The registry has no figure for a home with a different daily draw, and this page does not estimate one. The page on how the annual cost is calculated sets out the steps behind this figure and behind the running cost.
The high draw pattern stands for a larger household, or one where showers and laundry overlap. This model's first hour rating is 80 gallons. The first hour rating is the gallons of hot water available in the first hour from a full tank. Its rated volume is 38 gallons. These figures describe the test conditions behind the 264 therms figure. A home that draws less hot water each day than the test assumes does not match those conditions. The registry gives no energy figure for such a home, so this page shows none. To compare other units, the water heater selector by fuel, space and size filters the registry by those three factors.
Within its class, the LOCHINVAR GCR-40 410 ranks 236th lowest energy use of 414. That rank is consistent with the position above the class median given at the top of this page. The yearly running cost is not written in this text. It depends on your state's average residential gas price, so the page calculates it from your ZIP code. You can try a different ZIP in the cost calculator for your own rate. The installed price appears in a separate block with its source and date. That price is a modeled range, not a quote.
