JETGLAS RE130L*-*****

The figure of 2,439 kWh applies only to an electric tank heater at the low draw pattern. This site computed it, not the registry, from the registry's UEF and the DOE test's daily hot-water draw for that pattern. UEF, the ratio of hot water delivered to energy used, is 0.92 for this model. The source is DOE CCD, retrieved 2026-09-19. The class median is 2,439 kWh, so the difference is 0 kWh. The data also rank the model 19th lowest energy use of 163, which is in the lowest quarter of its class. The supplied data give both the zero difference and that rank, and this page does not explain how the two fit together. A figure for any other draw pattern is not available here.

The first hour rating, the gallons of hot water available in the first hour from a full tank, is 42 gallons for this model, and the rated volume is 26 gallons. The energy figure fits a household whose daily hot-water use matches the low draw pattern, which the registry describes as a one- or two-person household. It does not describe a household that draws more hot water each day than the federal test does. For that household the real annual energy use would differ from 2,439 kWh, and the data hold no estimate. To compare tanks by fuel, space and size, use the water heater selector. To look up a unit in the same class by model number, use same-class replacement search.

The running cost is not stated in the text because it depends on your own utility electricity tariff. The energy figure of 2,439 kWh is the quantity to multiply by your rate per kilowatt-hour, and it holds only at the low draw pattern. The cost calculator on your own ZIP does this for you, and how the annual cost is calculated sets out the method. An installed price range is not published for this model. Its ratings, a first hour rating of 42 gallons and a rated volume of 26 gallons, lie outside the range the cost database's model was fitted on, and that range is not stretched past its limits.
