JETGLAS RG2MH30T*N
0.54 UEF DOE CCD · 2026-09-19Grade G: where this UEF sits among the 9 models in its class, lowest (G) to highest (A). A position, not an official label. How the grade is set
A gas tank, low draw pattern (a one- or two-person household).
Checking this listing: the JETGLAS RG2MH30T*N uses 142 therms of natural gas a year. That figure is at the low draw pattern, the standard daily hot-water usage DOE tests against. It sits at the class median of 142 therms, a difference of 0 therms, among 9 gas tank models.
Energy use per year
142 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 equal to the median of 142 therms for the 9 models registered in the same heater type and draw pattern; it ranks 4 of 9, lowest energy first.
Solid line: this model (142 therms). Dashed line: the class median.

What it costs to install
Not published: Installed cost range
This model's UEF lies outside the range NLR REMDB's cost model was fitted on, and the range is not stretched past it.
The annual energy figure on this page does not depend on this range and is unaffected.
Safety record
No CPSC recall names this model.
Checked against the CPSC recall database. CPSC does not publish a model-level match for this product category, so this list is curated by hand from the manufacturer's recall filings.

The registry lists a UEF, the ratio of hot water delivered to energy used, of 0.54 for this model. This site computed 142 therms a year from that UEF and the DOE test's daily hot-water draw for the low draw pattern. The registry supplies the UEF, and this site does the calculation. The fuel is natural gas, and the data come from DOE CCD, retrieved 2026-09-19. Its energy use ranks 4th lowest of 9 models, in the second-lowest quarter of its class. The class median is 142 therms, and this model's difference from it is 0 therms.
The low draw pattern describes a one- or two-person household. The first hour rating, the gallons of hot water available in the first hour from a full tank, is 50 gallons. Its rated volume is 29 gallons. The 142 therms figure applies only at the low draw pattern. For a household that matches the pattern, the rank of 4th lowest of 9 applies as well. A household that draws more hot water than the federal test does not match it. This page has no annual energy figure for any other draw pattern. Those readers can compare options with the water heater selector by fuel, space and size.
Running cost is not stated in the text, because it depends on your state's average residential gas price. The cost calculator on your own ZIP applies that price to the 142 therms figure. The methodology for the annual cost explains each step. At any one gas price, this model costs the same to run as a model at the class median. The class median is 142 therms, and this model's difference is 0 therms. Installed price is not published. This model's ratings lie outside the range the cost database's model was fitted on. The page does not stretch that range to cover it.
