LOCHINVAR GCRL-40 2**
0.58 UEF DOE CCD · 2026-09-19Grade G: where this UEF sits among the 288 models in its class, lowest (G) to highest (A). A position, not an official label. How the grade is set
A gas tank, medium draw pattern (a typical three- or four-person household, about 55 gallons on a busy morning).
If you are checking this LOCHINVAR GCRL-40 2** against the registry, it uses 191 therms of natural gas a year at the medium draw pattern, the standard daily hot-water usage DOE tests against. That is 6 therms above the class median of 185 therms, placing it 231st lowest of 288 gas tank models.
Energy use per year
191 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 185 therms for the 288 models registered in the same heater type and draw pattern; it ranks 231 of 288, lowest energy first.
Solid line: this model (191 therms). Dashed line: the class median.

The 191 therms figure is not a registry value. This site computed it from the registry's UEF, the ratio of hot water delivered to energy used, of 0.58, and the DOE test's daily hot-water draw for the medium draw pattern. That pattern stands for a typical household on a busy morning. The source is DOE CCD, retrieved 2026-09-19. The class median is 185 therms, taken across the 288 models registered as a gas tank at this pattern, and this model sits 6 therms above it. Its rank is 231st lowest of 288, which puts it in the highest quarter of its class for energy use. The methodology page shows how the calculation works.
The model has a first hour rating, the gallons of hot water available in the first hour from a full tank, of 64 gallons. Its rated volume is 38 gallons. Those two values describe delivery, not energy use, so they do not change the 191 therms figure. The figure suits a reader checking a household that draws hot water at the medium pattern, because that is the condition it was computed under. It suits less well a reader who wants the lowest energy use in the class, because the models ranked ahead of 231st lowest use less energy at the same draw. It also does not apply to a household with a different daily draw, since the data here holds no value for other draw patterns. The water heater selector filters by fuel, space and size.
Running cost is not written here because it depends on your state average residential gas price, and the text does not state one. Applying that price to 191 therms of natural gas gives the yearly cost at the medium pattern. The cost calculator does this on your own ZIP. A modeled installed-cost range appears in its own block on this page with its source and date. It is not a quote and is not repeated here. The data does not contain measured use in a specific home or energy at any other draw pattern. To compare within the same class, you can find a same-class replacement by model number. The 6 therms gap to the 185 therms median is a difference at the federal test's draw, not a prediction for your home.
