FRIEDRICH PROG30-32N RH63 MH *

0.6 UEF DOE CCD · 2026-09-19
F

Grade F: where this UEF sits among the 288 models in its class, lowest (G) to highest (A). A position, not an official label. How the grade is set

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

If you are checking the FRIEDRICH PROG30-32N RH63 MH *, here is its energy use. This gas tank uses 185 therms of natural gas a year at the medium draw pattern, the standard daily hot-water usage DOE tests against. That equals its class median of 185 therms, a difference of 0 therms, ranking 89th lowest of 288.


Energy use per year

185 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 equal to the median of 185 therms for the 288 models registered in the same heater type and draw pattern; it ranks 89 of 288, lowest energy first.

What it costs to install

Not published: Installed cost range

This model's rated tank size 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.

What these figures mean

This site calculates the 185 therms figure; the registry does not list it. The calculation uses the model's UEF, the ratio of hot water delivered to energy used. The 0.6 rating is combined with the DOE test's daily hot-water draw for the medium pattern. The rating comes from the DOE CCD registry, retrieved 2026-09-19. The class is the 288 models registered as a gas tank at the medium draw pattern. Their median is also 185 therms. This model ranks 89th lowest in energy use, which places it in the second-lowest quarter of its class. The figure applies only at the federal test's daily draw. The registry does not give your actual gas use at home.

The medium draw pattern stands for a typical household's daily hot-water use. The 185 therms estimate fits homes whose use is close to that test day. The tank holds 28 gallons. Its first hour rating, the gallons of hot water available in the first hour from a full tank, is 52 gallons. A household that needs more than 52 gallons in its busiest hour would draw beyond what that rating covers. This data does not give the model's energy use at any other draw pattern. To compare other units, use the water heater selector by fuel, space and size. To check a unit in the same class, find a same-class replacement by model number.

The running cost is not stated here because it depends on your state's average residential gas price. The page uses your ZIP to apply that price to the 185 therms of natural gas at the medium draw pattern. You can run the same figure in the water heater cost calculator for your ZIP. The steps are set out in how the annual running cost is calculated. No installed price range is published for the FRIEDRICH PROG30-32N RH63 MH *. Its ratings lie outside the range that the cost database's model was fitted on. That range is not extended to cover this model. The installed price of this unit is therefore unknown on this page.
