JETGLAS RG2DV40S*N-***

It holds 38 gallons in the test, 2 gallons less than its 40-gallon sold size. Over one hour from a full tank, it gave 62 gallons in the test (its first-hour rating). Its tank holds 38 gallons, so reheating adds 24 gallons during the first hour. In the first hour, 671 of the 763 gas storage models give more hot water. The median gas storage model gives 78 gallons in its first hour.

As of Oct 26, 2026, it was not listed as ENERGY STAR certified. In tests, 60% of the energy it uses ends up as hot water (UEF 0.60). Its test simulated a day of medium hot water use (its draw pattern). Of 288 gas storage models with the same draw pattern, 88 have a higher UEF and 103 a lower one. Its UEF is the median for its type and draw pattern. The water took in 75% of the energy used to reheat it (its recovery efficiency).

Its 3 model numbers are RG2DV40S*N-***, RG2DV40S*X-***, and URG2DV40S*N-***. All of its test figures are shared by one other basic model. That one is listed under the Bradford White brand. For the full group, see the Bradford White RG2DV40S*N-***.
