RELIANCE WATER HEATERS HPTV-66 2**
3.2 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 verifying the RELIANCE WATER HEATERS HPTV-66 2**, this electric tank uses 1,550 kWh a year at the high draw pattern, the standard daily hot-water usage DOE tests against. That figure sits 244 kWh above its class median of 1,306 kWh. It ranks 162nd lowest energy use of 194 comparable models.
Energy use per year
1,550 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 162 of 194, lowest energy first.
Solid line: this model (1,550 kWh). Dashed line: the class median.

UEF 3.2 · Grade D Price it on your ZIP
The 1,550 kWh figure is computed by this site, not published by the registry. It combines the registry's UEF, the ratio of hot water delivered to energy used, with the DOE test's daily hot-water draw for the high draw pattern. This model's UEF is 3.2, from DOE CCD data retrieved on 2026-09-19. The total holds only at the federal test's daily draw. A home that draws more or less hot water than the test will use a different amount. This data does not include that amount. The class median quoted above is computed for the same high draw pattern. The calculation steps are set out in how the annual energy and cost figures are calculated.
The high draw pattern describes a larger household, or one where showers and laundry overlap. For that use, the registry lists a first hour rating, the gallons of hot water available in the first hour from a full tank, of 76 gallons. The registry gives a rated volume of 68 gallons. A plumber or seller checking a listing can compare these registry values with the unit's label. This data cannot show whether the tank covers a specific home's peak demand, because that depends on the home's own usage. Readers who need a different size or fuel can narrow the field with the water heater selector by fuel, space and size.
The 244 kWh gap noted above puts this model in the highest quarter of its class for energy use. Its class is the 194 models registered as an electric tank at the high draw pattern. A reader who wants lower test energy use within the same class can find a same-class replacement by model number. This text does not state the running cost for 1,550 kWh of electricity. That cost depends on the reader's own utility electricity tariff. The page therefore computes it from the reader's ZIP in the cost calculator for your own ZIP. The 244 kWh gap is priced at that same rate. The installed price range appears in its own block as a modeled range, not a quote.
