FRIEDRICH PROPH40 T0 RH120
2.59 UEF DOE CCD · 2026-09-19Grade D: 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).
Checking the FRIEDRICH PROPH40 T0 RH120: it uses 1,254 kWh of electricity a year at the medium draw pattern, the standard daily hot-water usage DOE tests against. That is 2,277 kWh below the class median of 3,531 kWh across 426 electric tank models registered at that draw pattern.
Energy use per year
1,254 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 129 of 426, lowest energy first.
Solid line: this model (1,254 kWh). Dashed line: the class median.

What it costs to install
Not published: Installed cost range
This model's UEF lies outside the range NLR REMDB's cost model was fitted on, and the range is not stretched past it.
The annual energy figure on this page does not depend on this range and is unaffected.
Safety record
No CPSC recall names this model.
Checked against the CPSC recall database. CPSC does not publish a model-level match for this product category, so this list is curated by hand from the manufacturer's recall filings.

The 1,254 kWh figure is computed by this site, not by the registry. It is derived 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 draw pattern. The UEF is 2.59. The fuel is electricity, and the source is DOE CCD, retrieved 2026-09-19. This model sits 2,277 kWh below the class median of 3,531 kWh. Its rank is 129th lowest energy use of 426, which is in the second-lowest quarter of its class for energy use. The comparison covers only electric tank models registered at the medium draw pattern, so it says nothing about other fuels or other draw patterns. The calculation method explains how the annual cost is derived from this energy figure.
The first hour rating, the gallons of hot water available in the first hour from a full tank, is 43 gallons, and the rated volume is 37 gallons. The 1,254 kWh figure suits a household whose use resembles the medium draw pattern, which represents a typical household on a busy morning. It does not describe a household that draws more than that pattern. A household that needs more hot water in a single hour than 43 gallons is outside what this rating covers, and energy use for heavier demand is not available on this page. The installed price range is not published because this model's ratings lie outside the range the cost database's model was fitted on. The range is not stretched past it. To compare other units, use the selector by fuel, space and size, or find a same-class replacement by model number.
The running cost depends on your own utility electricity tariff, so this text states no cost figure. The cost calculator on your own ZIP applies your rate to the 1,254 kWh figure. At any single rate, the 2,277 kWh gap from the class median of 3,531 kWh carries over as a cost gap in the same direction, because both values are measured at the medium draw pattern. This page cannot show what you pay. It does not know your rate, your actual hot-water use or your household's draw pattern. The figure is a test-based value at the federal test's daily draw, not a measurement of your home. The rank of 129th lowest of 426 orders models by energy use only. It does not rank them by cost, price or hot-water capacity.
