| Model number | Storage volume (gal) | UEF | First-hour rating (gal) | Recovery efficiency | Draw pattern |
|---|---|---|---|---|---|

UEF is the uniform energy factor. A dash means the model has no such figure.
Starting full, it gives 54 gallons of hot water in its first hour of use. Reheating lets it give 11 gallons beyond the 43 gallons in its tank. In the first hour, 239 of the 477 electric storage models give more hot water. The median electric storage model gives 55 gallons in the first hour of the test.
In tests, 93% of the energy it uses ends up as hot water (UEF 0.93). Its test simulated a day of medium hot water use (its draw pattern). Among 297 electric storage models on its draw pattern, 20 have a higher UEF. A UEF of 0.92 is the median for its type and draw pattern. The water took in 98% of the energy used to reheat it (its recovery efficiency).
It is the basic model for ELDS52-FTB and ELDS52-TB. All of its test figures are shared by 2 other basic models. Of those, one or more are under the Friedrich and Rheem brands. For the full group, see the Rheem PROE47 S2 RH95 page.
