JETGLAS RE230LN*-*****

0.92 UEF DOE CCD · 2026-09-19
G

Grade G: where this UEF sits among the 163 models in its class, lowest (G) to highest (A). A position, not an official label. How the grade is set

An electric tank, low draw pattern (a one- or two-person household).

If you are verifying this unit, the JETGLAS RE230LN*-***** uses 2,439 kWh a year at the low draw pattern, the standard daily hot-water usage DOE tests against. That equals its class median of 2,439 kWh, a difference of 0 kWh, among 163 electric tank models.


Energy use per year

2,439 kWh a year

Computed by this site from the registry's UEF and the federal test's daily hot-water draw for this draw pattern. What it costs depends on the electricity rate where you live.

That is equal to the median of 2,439 kWh for the 163 models registered in the same heater type and draw pattern; it ranks 19 of 163, lowest energy first.

This model: 2,439 kWh

What it costs to install

Not published: Installed cost range

This model's rated tank size lies outside the range NLR REMDB's cost model was fitted on, and the range is not stretched past it.

The annual energy figure on this page does not depend on this range and is unaffected.


Safety record

No CPSC recall names this model.

Checked against the CPSC recall database. CPSC does not publish a model-level match for this product category, so this list is curated by hand from the manufacturer's recall filings.

What these figures mean

The figure of 2,439 kWh is not a registry entry. This site computed it, not the registry. It uses the registry's UEF, the ratio of hot water delivered to energy used, and the DOE test's daily hot-water draw for the low draw pattern. The UEF listed for this model is 0.92. The condition for the figure is the low draw pattern, a one- or two-person household. The source is the DOE CCD, retrieved 2026-09-19, and the fuel is electricity. A household whose hot-water use differs from the test draw will see different energy use, and the calculation method shows how the annual figure is derived from these two inputs.

Among the 163 models registered as an electric tank at the low draw pattern, this one has the 19th lowest energy use, which is in the lowest quarter of its class. Its 2,439 kWh matches the class median of 2,439 kWh, stated above. The supplied data do not explain how a model at the median also ranks 19th lowest, so both facts are reported as given. This model suits the household the low draw pattern describes. Its first hour rating, the gallons of hot water available in the first hour from a full tank, is 41 gallons, and its rated volume is 26 gallons. Figures for higher draw patterns are not available here, so this page does not show how the model would perform for a larger household.

The running cost is not stated in this text because it depends on your own utility electricity tariff. To apply 2,439 kWh to your rate, use the cost calculator with your ZIP; the result holds only for the low draw pattern. An installed price range is not published for this model. Its ratings lie outside the range the cost database's model was fitted on, and that range is not stretched past it. If your household is larger or smaller than the low draw pattern assumes, the water heater selector filters by fuel, space and size. The replacement finder lists a same-class model by model number.
