GSW WATER HEATERS GPVL-40 2**
0.67 UEF DOE CCD · 2026-09-19Grade D: 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).
For a check on this unit: GSW WATER HEATERS GPVL-40 2** uses 165 therms of natural gas a year. That is at the medium draw pattern, the standard daily hot-water usage DOE tests against. It sits 20 therms below the class median of 185 therms.
Energy use per year
165 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 below the median of 185 therms for the 288 models registered in the same heater type and draw pattern; it ranks 20 of 288, lowest energy first.
Solid line: this model (165 therms). Dashed line: the class median.

UEF 0.67 · Grade D Price it on your ZIP
The registry lists a UEF, the ratio of hot water delivered to energy used, of 0.67 for this model. This site computed 165 therms from that UEF and the daily hot-water draw for the medium draw pattern. The registry does not publish that annual figure. The source is DOE CCD, retrieved 2026-09-19. Among the 288 models registered as a gas tank at this draw pattern, this one has the 20th lowest energy use. That puts it in the lowest quarter of its class. The gap to the class median of 185 therms is 20 therms.
The first hour rating, the gallons of hot water available in the first hour from a full tank, is 73 gallons here. The rated volume is 38 gallons. The medium draw pattern describes a typical mid-sized household on a busy morning. The energy figure applies to that usage only. Energy use at other draw patterns is not available in the registry data, so none is stated. If your peak-hour demand differs, compare sizes with the water heater selector, which filters by fuel, space and size. Households that fit the medium pattern can read the 165 therms figure directly.
The running cost depends on your state average residential gas price, and this text states no price. The cost calculator applies your own ZIP to the 165 therms figure. The annual cost methodology explains each step of that calculation. The gap of 20 therms from the 185 therms median is measured in natural gas, so its cost also follows your rate. The installed price range appears in its own block on this page. It is a modeled range, not a quote.
