UEF is the uniform energy factor. A dash means the model has no such figure.

It holds 37 gallons in the test, 3 gallons less than its 40-gallon sold size. Over one hour from a full tank, it gave 54 gallons in the test (its first-hour rating). Its tank holds 37 gallons, so reheating adds 17 gallons during the first hour. Of 763 gas storage models, 734 give more hot water in the first hour. Among gas storage models, the median first-hour rating is 78 gallons.

As of Oct 26, 2026, it was not listed as ENERGY STAR certified. In tests, 59% of the energy it uses ends up as hot water (UEF 0.59). Its test simulated a day of medium hot water use (its draw pattern). Of 288 gas storage models with the same draw pattern, 185 have a higher UEF and 58 a lower one. For its type and draw pattern, the UEF runs from 0.57 to 0.75. The water took in 78% of the energy used to reheat it (its recovery efficiency).

Its 2 model numbers are RG2MH40T*N and RG2MH40T*X. There is one more basic model with the same test figures. The brand name on that one is JETGLAS.
