RELIANCE WATER HEATERS ENL-30 1**
0.9 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).
Checking this listing: RELIANCE WATER HEATERS ENL-30 1**, an electric tank, uses 2,494 kWh a year at the low draw pattern, the standard daily hot-water usage DOE tests against, here a one- or two-person household. That is 55 kWh above the class median of 2,439 kWh, and it ranks 122nd lowest for energy use among 163 models.
Energy use per year
2,494 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 122 of 163, lowest energy first.
Solid line: this model (2,494 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 figure of 2,494 kWh is not a registry value. This site computed it from the registry's UEF, the ratio of hot water delivered to energy used, which is 0.9 for this model. It also used the DOE test's daily hot-water draw for the low draw pattern. The source is DOE CCD, retrieved 2026-09-19. The result applies only to that draw pattern, with electricity as the fuel. It sits 55 kWh above the class median of 2,439 kWh, taken across the 163 models registered as an electric tank at the low draw pattern. That places the model in the second-highest quarter of its class for energy use. The data used here does not show what causes that gap, so this page does not explain it.
The low draw pattern matches a one- or two-person household, and the energy figure holds only 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 44 gallons, and a rated volume of 26 gallons. A household of that size can compare its own expectation with 2,494 kWh and with the class median of 2,439 kWh. A household that draws more hot water than the test assumes is not described by 2,494 kWh. This page has no figure for other draw patterns; that value is not available. The water heater selector filters by fuel, space and size, and a same-class replacement by model number can be looked up for comparison.
Running cost is not stated in the text, because it depends on the electricity tariff the reader pays. The annual energy of 2,494 kWh at the low draw pattern is multiplied by that rate. The cost calculator does this from the reader's ZIP, and the methodology page explains how the annual cost is calculated. Because the model sits 55 kWh above the class median of 2,439 kWh, its cost is above the median model's at any single rate, and the size of that difference depends on the rate. The installed price range is not published. This model's ratings, a first hour rating of 44 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 limit.
