RELIANCE WATER HEATERS HPTS-50 2**
3.8 UEF DOE CCD · 2026-09-19Grade A: 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 verifying the RELIANCE WATER HEATERS HPTS-50 2**, it uses 855 kWh of electricity a year at the federal test's daily draw. That figure belongs to the medium draw pattern, the standard daily hot-water usage DOE tests against. It sits 2,676 kWh below the 3,531 kWh median for electric tanks at that pattern, 16th lowest of 426.
Energy use per year
855 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 16 of 426, lowest energy first.
Solid line: this model (855 kWh). Dashed line: the class median.

UEF 3.8 · Grade A Price it on your ZIP
The 855 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, and the DOE test's daily hot-water draw for the medium pattern. For the HPTS-50 2**, the UEF is 3.8, as listed in the DOE CCD retrieved 2026-09-19. The result holds only at that test draw. A home that uses more or less hot water in a day will use a different amount of electricity. That amount is not available here. The 2,676 kWh gap to the class median also describes test conditions, not real homes. The conversion steps are set out in how this site calculates annual energy and cost.
The medium draw pattern stands for a typical household's daily hot-water use, including a busy morning. This model's first hour rating, the gallons of hot water available in the first hour from a full tank, is 65 gallons. Its rated volume is 46 gallons. These figures fit a home whose busiest hour stays within 65 gallons of hot water. They do not describe a home whose peak hour draws more than that. The 855 kWh figure applies only to the medium pattern and does not carry over to other draw patterns. For other fuels, spaces or sizes, see the water heater selector by fuel, space and size. To match this unit within its own class, use the same-class replacement search by model number.
No running cost appears in this text. The cost of 855 kWh a year depends on your own utility's electricity tariff, which this page does not assume. The page computes it from your ZIP instead, and the running-cost calculator for your own ZIP lets you check it on your own rate. The 2,676 kWh difference from the 3,531 kWh median is also measured in kWh. Its value in money depends on the same tariff, so it is not stated here. The installed price shown elsewhere on this page is a modeled range with its own source and date, not a quote. The ranking of 16th lowest of 426 is based on kWh, so a different tariff does not change it.
