U.S. CRAFTMASTER FPTU-50 1**

3.35 UEF DOE CCD · 2026-09-19
B

Grade B: 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 U.S. CRAFTMASTER FPTU-50 1**, this electric tank uses 970 kWh of electricity a year. That figure is at the medium draw pattern, the standard daily hot-water usage DOE tests against. It sits 2,561 kWh below the class median of 3,531 kWh, ranking 101st lowest of 426.


Energy use per year

970 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 101 of 426, lowest energy first.

This model: 970 kWh

What these figures mean

This site calculated the 970 kWh figure. The registry does not publish it. The calculation uses the model's UEF, the ratio of hot water delivered to energy used, and the daily draw from the DOE test. The registry lists a UEF of 3.35 for this unit, from DOE CCD data retrieved 2026-09-19. The calculation uses the test's fixed daily hot-water use, so the figure holds only at that condition. A household that uses more or less hot water than the test assumes would use a different amount of energy. How much different is not available here. The steps are set out in how the annual cost is calculated. The comparison class is the 426 models registered as an electric tank at the medium draw pattern.

The registry also lists a first hour rating, the gallons of hot water available in the first hour from a full tank. For this model it is 66 gallons, from a rated volume of 46 gallons. A plumber or seller checking a label can compare these two values directly. The model fits a household at the medium draw pattern whose busiest hour stays within 66 gallons. A household whose busiest hour needs more than that is outside what this rating covers. Its energy rank of 101st lowest of 426 applies only within this class. It does not apply to other fuels or other draw patterns. To check other models in the same class, use the same-class replacement search by model number.

This page gives no running cost for this model. The cost depends on your own utility's electricity tariff, which this page does not know. Multiply the 970 kWh figure by your rate to get the yearly cost at the medium draw pattern. The cost calculator for your own ZIP does that step with your local tariff. The 2,561 kWh gap below the class median applies whatever your rate is. Its value in money is not available until you enter your rate. Energy use away from the test draw is unknown, so any calculated cost holds only at the test condition. The installed price range on this page has its own block with its source and date. It is a modeled range, not a quote.
