FRIEDRICH PROG30-30N RH63 MH DV

0.57 UEF DOE CCD · 2026-09-19
A

Grade A: where this UEF sits among the 9 models in its class, lowest (G) to highest (A). A position, not an official label. How the grade is set

A gas tank, low draw pattern (a one- or two-person household).

The FRIEDRICH PROG30-30N RH63 MH DV is a gas tank water heater tested at a low draw, sized for a one- or two-person household. At the federal test's draw, it uses 134 therms of natural gas a year, 8 therms below the class median of 142 therms. It ranks 1st lowest energy use of 9 comparable models.


Energy use per year

134 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 below the median of 142 therms for the 9 models registered in the same heater type and draw pattern; it ranks 1 of 9, lowest energy first.

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.

What these figures mean

This page reports the FRIEDRICH PROG30-30N RH63 MH DV's annual energy use as computed by this site, not the registry. It combines the registry's UEF, the ratio of hot water delivered to energy used, with the DOE test's daily hot-water draw. That draw follows the draw pattern, the standard daily hot-water usage DOE tests against. Here that pattern is set to low. At that draw, the unit uses 134 therms of natural gas a year, drawn from DOE CCD data retrieved 2026-09-19. Its UEF of 0.57 determines how the draw pattern converts to a yearly figure, so the 134 therms figure applies only under the low draw pattern. A first hour rating, the gallons of hot water available in the first hour from a full tank, is 46 gallons. Rated volume is 29 gallons, rounding out this gas tank water heater's published identity.

The low draw pattern reflects a one- or two-person household's typical hot-water use, per the DOE test's assumptions for this model. Among the 9 models registered as a gas tank at the low draw pattern, this unit's 134 therms sits 8 therms below the class median of 142 therms. It ranks 1st lowest energy use of 9. A household outside that draw pattern, or one needing more than 46 gallons in the first hour, may find a different capacity or draw pattern a closer match. The selector by fuel, space and size covers other models. A same-class replacement by model number tool starts from this model's own 0.57 UEF and 134 therms figures.

Running cost is not stated here: it depends on the reader's own state average residential gas price. The page computes it from the reader's ZIP rather than naming a fixed value. The cost calculator on the reader's own ZIP applies 134 therms to a local rate. The methodology behind the annual cost figure explains how that cost is calculated from the registry's UEF and DOE CCD data. An installed price range is not published for this model. Its 0.57 UEF and 46-gallon first hour rating lie outside the range the cost database's model was fitted on, and the range is not stretched past it.
