RELIANCE WATER HEATERS HPTV-50 2**

3 UEF DOE CCD · 2026-09-19
C

Grade C: where this UEF sits among the 426 models in its class, lowest (G) to highest (A). A position, not an official label. How the grade is set

An electric tank, medium draw pattern (a typical three- or four-person household, about 55 gallons on a busy morning).

If you are checking the RELIANCE WATER HEATERS HPTV-50 2**, this site computes 1,083 kWh of electricity a year for it. That figure holds at the medium draw pattern, the standard daily hot-water usage DOE tests against. It sits 2,448 kWh below the 3,531 kWh median of the 426 electric tank models at that draw pattern.


Energy use per year

1,083 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 3,531 kWh for the 426 models registered in the same heater type and draw pattern; it ranks 116 of 426, lowest energy first.

This model: 1,083 kWh

What these figures mean

The 1,083 kWh figure does not appear in the registry itself. This site computed it from the registry's UEF, the ratio of hot water delivered to energy used. It combined that ratio with the DOE test's daily hot-water draw for the medium draw pattern. The registry lists a UEF of 3 for the HPTV-50 2**. The inputs come from the DOE CCD, retrieved 2026-09-19. On that computed figure, the model ranks 116th lowest energy use of 426 in its class. That places it in the second-lowest quarter of its class for energy use. If your household draws more or less hot water than the test assumes, your actual use may differ from 1,083 kWh.

The HPTV-50 2** has a rated volume of 46 gallons. Its first hour rating, the gallons of hot water available in the first hour from a full tank, is 52 gallons. These figures fit a home whose busiest hour of hot-water use stays within 52 gallons. The energy figure fits best where daily use is close to the medium draw pattern. These numbers do not describe a home that regularly needs more than 52 gallons in its peak hour. For that case, the water heater selector by fuel, space and size filters models by size. If you are matching an existing unit, you can find a same-class replacement by model number.

This page gives no running cost in the text. The cost of 1,083 kWh a year depends on your own utility's electricity tariff. The cost calculator for your own ZIP applies your local rate to that figure. The same rate also applies to the 2,448 kWh gap to the class median described above. The page on how the annual cost is calculated explains how the rate and the energy figure combine. The installed price range appears in its own block, with its source and date. It is a modeled installed-cost range, not a quote. Your own hot-water use is not available to this page, so the 1,083 kWh figure reflects only the test's medium draw.
