LOCHINVAR ENJ-30 1**
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).
If you are checking the LOCHINVAR ENJ-30 1**, an electric tank water heater, it uses 2,466 kWh of electricity a year. That figure belongs to the low draw pattern, the standard daily hot-water usage DOE tests against. It is 27 kWh above the 2,439 kWh median of the 163 electric tank models registered at that pattern.
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 registry does not print the 2,466 kWh figure. This site computes it from 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 pattern. The listed UEF for the ENJ-30 1** is 0.91, taken from DOE CCD records retrieved 2026-09-19. The figure applies only at that test draw. A household with a different daily draw would get a different annual figure, and the registry does not list one. Among the 163 electric tank models at the low draw pattern, this unit ranks 88th when the class is ordered from lowest energy use. Its gap of 27 kWh is measured against a class median of 2,439 kWh.
DOE applies the low draw pattern to a household with low daily hot-water use. The ENJ-30 1** has a rated volume of 26 gallons. Its first hour rating, the gallons of hot water available in the first hour from a full tank, is 43 gallons. The model was tested at the low draw pattern, and its registry figures describe that test only. A home whose busiest hour needs more than 43 gallons is outside what this rating covers. For such a home, the registry figures for this model do not describe how it will perform. To compare models by other criteria, use the water heater selector by fuel, space and size. To match this class, find a same-class replacement by model number.
The running cost is not stated here because it depends on your own utility's electricity tariff. The page computes it from your ZIP by applying your rate to the 2,466 kWh figure at the low draw pattern. The water heater cost calculator for your ZIP shows that result. The page on how the annual cost is calculated sets out each step. An installed price range is not published for the ENJ-30 1**. Its ratings lie outside the range the cost database's model was fitted on, and the site does not stretch that range past it. This page therefore does not have an installed price for this unit.
