Richmond 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).

Checking the Richmond PROG30-30N RH63 MH DV, a gas tank water heater? At the low draw pattern, the standard daily hot-water usage DOE tests against, it uses 134 therms of natural gas a year. That is 8 therms below the class median of 142 therms, and it ranks 1st lowest of 9 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.

This model: 134 therms

Solid line: this model (134 therms). 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.

What these figures mean

The 134 therms figure is computed by this site, not by the registry. It combines the registry's UEF, the ratio of hot water delivered to energy used, of 0.57 with the daily hot-water draw that DOE's test assigns to the low draw pattern. The source is the DOE CCD, retrieved 2026-09-19. The comparison class is the 9 models registered as a gas tank at the low draw pattern, where the median is 142 therms. This model sits 8 therms below that median, which places it in the lowest quarter of its class for energy use. The figure describes the test's standard draw only. A household that draws more or less hot water than the test assumes will use a different amount of gas.

This model suits a household whose hot-water use resembles the low draw pattern, which the registry describes as a small household. Its first hour rating, the gallons of hot water available in the first hour from a full tank, is 46 gallons, and its rated volume is 29 gallons. A plumber or seller can compare those two ratings with the household's peak demand. It suits a household with heavier use less well, because the 134 therms figure and the rank of 1st of 9 do not carry over to another draw pattern. This page gives no energy figures for other draw patterns. To narrow the choice by fuel, space and size, use the water heater selector.

The running cost is not written here because it depends on your state's average residential gas price. You can apply that price to the 134 therms figure yourself, or enter your ZIP in the cost calculator. The methodology for the annual cost explains how the calculation works. An installed price range is not published for the Richmond PROG30-30N RH63 MH DV. Its ratings, a UEF of 0.57 and a first hour rating of 46 gallons, lie outside the range the cost database's model was fitted on, and the range is not stretched past it. To compare within the same class, you can find a same-class replacement by model number.
