FRIEDRICH PROG50-38U RH60 EC1*
0.63 UEF DOE CCD · 2026-09-19Grade G: where this UEF sits among the 414 models in its class, lowest (G) to highest (A). A position, not an official label. How the grade is set
A gas tank, high draw pattern (a larger household, or one where showers and laundry overlap).
If you are checking this gas tank water heater, the FRIEDRICH PROG50-38U RH60 EC1* uses 269 therms of natural gas a year at the high draw pattern, the standard daily hot-water usage DOE tests against. That is 9 therms above the class median of 260 therms, and 320th lowest energy use of 414 models.
Energy use per year
269 therms 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 natural gas rate where you live.
That is above the median of 260 therms for the 414 models registered in the same heater type and draw pattern; it ranks 320 of 414, lowest energy first.
Solid line: this model (269 therms). Dashed line: the class median.

The registry lists a UEF, the ratio of hot water delivered to energy used, of 0.63 for this model. This site computed the 269 therms figure from that UEF and the DOE test's daily hot-water draw for the high draw pattern. The registry does not publish the figure itself. The source is the DOE CCD, retrieved 2026-09-19. The class median for the 414 gas tank models at this draw pattern is 260 therms, so this model sits 9 therms above it. Its rank of 320th lowest places it in the highest quarter of its class for energy use. The figure describes the federal test's draw, not any household's real use. The methodology page explains how the annual cost is calculated.
The high draw pattern describes a larger household, or one where showers and laundry overlap. For that pattern, this model has a first hour rating, the gallons of hot water available in the first hour from a full tank, of 86 gallons, with a rated volume of 48 gallons. It may suit a reader who needs a gas tank registered at the high draw pattern and accepts energy use 9 therms above the class median of 260 therms. It suits less well a reader whose main aim is low annual energy, given its rank of 320th lowest of 414. Readers can compare by fuel, space and size with the water heater selector, or find a same-class replacement by model number. The data here does not state whether the rating covers any one household's peak use.
The running cost is not stated in the text. It depends on the state average residential gas price, and this page assumes no rate. The cost is the 269 therms of natural gas at the high draw pattern multiplied by the reader's own rate. At any given gas price, this model's yearly gas cost is higher than that of a model at the class median of 260 therms. The gap equals the price multiplied by 9 therms. The cost calculator for your own ZIP computes the figure from your state's price. The installed price range is shown in its own block with its source and date. It is a modeled installed-cost range, not a quote, and it is not restated here.
