JETGLAS RE240S*-*****
0.91 UEF DOE CCD · 2026-09-19Grade 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).
You are checking the JETGLAS RE240S*-*****, an electric tank water heater. This site calculates it uses 2,466 kWh of electricity a year at the low draw pattern, the standard daily hot-water usage DOE tests against. That is 27 kWh above its class median of 2,439 kWh, ranking 88th lowest in energy use of 163 models.
Energy use per year
2,466 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 above the median of 2,439 kWh for the 163 models registered in the same heater type and draw pattern; it ranks 88 of 163, lowest energy first.
Solid line: this model (2,466 kWh). Dashed line: the class median.

What it costs to install
Not published: Installed cost range
This model's UEF 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.

The 2,466 kWh figure does not come from the registry itself. This site computed it from two inputs. The first is the registry's UEF, the ratio of hot water delivered to energy used, which is 0.91 for this model. The second is the daily hot-water draw the DOE test sets for the low draw pattern. The rating data come from the DOE CCD, retrieved 2026-09-19. The figure therefore holds only at that test draw. At a different daily draw the annual use would differ, and this page does not calculate that case. The steps are set out in how the annual energy and cost are calculated.
The low draw pattern represents a one- or two-person household. For that use, the model has a first hour rating, the gallons of hot water available in the first hour from a full tank, of 48 gallons. Its rated volume is 36 gallons. The class comparison above covers only the 163 electric tank models registered at the low draw pattern. Models tested at other draw patterns are not ranked against it. A household that draws more hot water each day than the low pattern falls outside the condition behind the 2,466 kWh figure. For that case, the water heater selector by fuel, space and size lists other models. You can also find a same-class replacement by model number.
No running cost appears in this text. It depends on your own utility electricity tariff, which this page does not know. The cost calculator on your own ZIP applies your local rate to the 2,466 kWh figure. The installed price range for this model is not published. Its ratings, including the 0.91 UEF and the 36-gallon rated volume, lie outside the range the cost database's model was fitted on. The site does not stretch that model past its fitted range. Any installed price for this unit is therefore unknown here.
