RELIANCE WATER HEATERS HPTV-80 2**

3 UEF DOE CCD · 2026-09-19
D

Grade D: 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 model's energy use, RELIANCE WATER HEATERS HPTV-80 2** uses 1,654 kWh a year at the high draw pattern, the standard daily hot-water usage DOE tests against. That is 348 kWh above the class median of 1,306 kWh, and it ranks 167th lowest energy use of 194 models.


Energy use per year

1,654 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 1,306 kWh for the 194 models registered in the same heater type and draw pattern; it ranks 167 of 194, lowest energy first.

This model: 1,654 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 registry lists RELIANCE WATER HEATERS HPTV-80 2** as an electric tank at the high draw pattern. Its annual energy figure of 1,654 kWh is electricity use at the federal test's daily hot-water draw. It does not describe any particular home. This site computed the figure, not the registry, from the registry's UEF of 3 and the DOE test's daily draw for this pattern. UEF, the ratio of hot water delivered to energy used, is the rating that drives the result. The source is DOE CCD, retrieved 2026-09-19. The steps of the calculation are set out in how the annual cost is calculated.

The high draw pattern fits a larger household, or one where showers and laundry overlap. This model has a first hour rating, the gallons of hot water available in the first hour from a full tank, of 93 gallons, and a rated volume of 82 gallons. Whether those ratings meet a particular household's demand is not something the registry data settles. On energy use, the model sits 348 kWh above the class median of 1,306 kWh, at 167th lowest of 194, in the highest quarter of its class. A reader whose priority is low annual electricity use may want to compare other models. The selector by fuel, space and size and the same-class replacement search by model number both support that comparison.

A running cost is not written here because it depends on your own utility electricity tariff, and this page assumes no rate. The 1,654 kWh figure is the quantity to multiply by that rate. Use the cost calculator on your own ZIP to get the cost at your local tariff. Actual use in a home depends on how much hot water it draws, so it can differ from 1,654 kWh. This page holds no measured household data. An installed price range is also not published for this model. Its ratings lie outside the range the cost database's model was fitted on, and the range is not stretched past it.
