RELIANCE WATER HEATERS HPTS-80 2**
3.88 UEF DOE CCD · 2026-09-19Grade B: where this UEF sits among the 194 models in its class, lowest (G) to highest (A). A position, not an official label. How the grade is set
An electric tank, high draw pattern (a larger household, or one where showers and laundry overlap).
If you are checking this unit's figures, RELIANCE WATER HEATERS HPTS-80 2** uses 1,279 kWh of electricity a year at the high draw pattern. A draw pattern is the standard daily hot-water usage DOE tests against. That is 27 kWh below the class median of 1,306 kWh across 194 electric tank models.
Energy use per year
1,279 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 below the median of 1,306 kWh for the 194 models registered in the same heater type and draw pattern; it ranks 72 of 194, lowest energy first.
Solid line: this model (1,279 kWh). Dashed line: the class median.

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.

UEF 3.88 · Grade B Price it on your ZIP
The figure of 1,279 kWh was computed by this site, not by the registry. The registry lists a UEF, the ratio of hot water delivered to energy used, of 3.88. The site combined it with the DOE test's daily hot-water draw for the high draw pattern. The source is DOE CCD, retrieved 2026-09-19. Among the 194 electric tank models at this draw pattern, the unit has the 72nd lowest energy use. That puts it in the second-lowest quarter of its class. Its use is 27 kWh below the class median of 1,306 kWh. The method is set out on the page about how the annual cost is calculated.
The high draw pattern describes a larger household, or one where showers and laundry overlap. The figure of 1,279 kWh applies to that use only, and this page has no energy figure for other draw patterns. The registry lists a first hour rating, the gallons of hot water available in the first hour from a full tank, of 95 gallons. The rated volume is 82 gallons, but whether those gallons cover a particular household is not something this data shows. To compare units by fuel, space and size, use the selector by fuel, space and size. To look up a unit of the same class, use same-class replacement by model number.
The running cost is not stated here because it depends on your own utility electricity tariff. Annual cost is the 1,279 kWh multiplied by your rate per kilowatt-hour, at the high draw pattern. The cost calculator on your own ZIP does that step with the tariff for your location. A different daily draw than the federal test's would change the result. The installed price range is not published for this model, and this page does not estimate one. Its ratings, including the UEF of 3.88 and the rated volume of 82 gallons, lie outside the range the cost database's model was fitted on. The range is not stretched past that limit.
