UEF is the uniform energy factor. A dash means the model has no such figure.
Sold as 30 gallons, it holds 30 gallons in the test. Over one hour from a full tank, it gave 42 gallons in the test (its first-hour rating). That is 12 gallons more than its tank holds, since it reheats during the hour. Of 477 electric storage models, 416 give more hot water in the first hour. Among electric storage models, the median first-hour rating is 55 gallons.
In tests, 92% of the energy went to hot water, so its UEF is 0.92. Its test ran at the low level of daily hot water use. Its UEF is lower than that of 12 of the 157 electric storage models with its draw pattern. On its draw pattern, its UEF is also the median electric storage UEF. When it reheats water in the test, 98% of the energy it uses ends up in the water.
There are 2 more basic models with the same test figures. Of those, one or more are under the Hubbell and VAUGHN brands. For the full group, see the Hubbell MP30F.
