A. O. SMITH HPTV-80 2**
3 UEF DOE CCD · 2026-09-19Grade 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 the A. O. SMITH HPTV-80 2** against the registry, this site puts its energy use at 1,654 kWh of electricity a year. That figure belongs to the high draw pattern, the standard daily hot-water usage DOE tests against. At that draw, it sits 348 kWh above its class median of 1,306 kWh.
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.
Solid line: this model (1,654 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.

The 1,654 kWh figure is not a value the registry publishes. This site computed it from the registry's UEF, the ratio of hot water delivered to energy used. It also used the DOE test's daily hot-water draw for the high draw pattern. The registry lists a UEF of 3 for this electric tank. The DOE CCD data behind the figure was retrieved on 2026-09-19. A household whose daily draw differs from the test's draw will use a different amount. This page has no data on how large that difference would be. The steps behind the figure are set out in how this site calculates annual energy and cost.
The class for this comparison is the 194 models registered as an electric tank at the high draw pattern. This model is 167th lowest in energy use among them. That places it in the highest quarter of its class for energy use. The high draw pattern fits a larger household, or one where showers and laundry overlap. For that kind of household, the registry lists a first hour rating of 93 gallons. The first hour rating is the gallons of hot water available in the first hour from a full tank. The rated volume is 82 gallons. To check other models in the same class, use the same-class replacement search by model number.
The text on this page states no running cost. The cost of 1,654 kWh of electricity a year depends on your own utility tariff. So the page computes it from your ZIP instead of estimating it here. The running-cost calculator for your ZIP shows that result. At any single rate, this model's energy cost is higher than a model at the class median, because it uses more energy. An installed price range is 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. For a household with smaller daily hot-water needs, the high draw pattern figure does not describe its use. The selector by fuel, space and size covers other sizes.
