JETGLAS RG2MH40T*N
0.59 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 water heater's energy figure, here it is. The JETGLAS RG2MH40T*N, a gas tank, uses 188 therms of natural gas a year at the medium draw pattern, the standard daily hot-water usage DOE tests against. That is 3 therms above the class median of 185 therms.
Energy use per year
188 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 186 of 288, lowest energy first.
Solid line: this model (188 therms). Dashed line: the class median.

What it costs to install
Not published: Installed cost range
This model's rated tank size 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 figure of 188 therms was computed by this site, not by the registry. It combines the registry's UEF, the ratio of hot water delivered to energy used, with the daily hot-water draw of the DOE test. The registry lists a UEF of 0.59 for this model. The source is the DOE CCD, retrieved 2026-09-19. The steps are described on the annual cost methodology page. The figure holds only for the medium draw pattern, which describes a typical household on a busy morning. Real use in a home with a different pattern will differ, and this page does not estimate by how much.
Among the 288 models registered as a gas tank at the medium draw pattern, this unit ranks 186th lowest in energy use. It sits 3 therms above the class median of 185 therms, in the second-highest quarter of its class. The registry lists a first hour rating, the gallons of hot water available in the first hour from a full tank, of 54. The rated volume is 37 gallons. These ratings suit a household whose busiest hour stays within that first hour rating. Households that draw more hot water than that in one hour are a weaker match. To compare models in the same class, use the same-class replacement finder.
Running cost is not stated here, because it depends on the state average residential gas price. Multiply the 188 therms by the gas price in your state to get the yearly cost at the medium draw pattern. The cost calculator for your own ZIP does this for you. An installed price range is not published for this model. Its ratings, 54 gallons first hour and 37 gallons rated volume, lie outside the range the cost database's model was fitted on. The range is not stretched past that limit. If you need a different fuel, space or size, the water heater selector filters on those.
