FRIEDRICH PROG40-34N RH62 MH

0.59 UEF DOE CCD · 2026-09-19
G

Grade G: 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 this listing, the FRIEDRICH PROG40-34N RH62 MH gas tank heater uses 188 therms of natural gas a year. That figure holds at the medium draw pattern, the standard daily hot-water usage DOE tests against. It sits 3 therms above the 185 therms median of the 288 gas tank models at that draw pattern.


Energy use per year

188 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 185 therms for the 288 models registered in the same heater type and draw pattern; it ranks 186 of 288, lowest energy first.

What these figures mean

The 188 therms figure is computed by this site, not by the registry. It combines two inputs from the DOE CCD, retrieved 2026-09-19. The first is the registry's UEF, the ratio of hot water delivered to energy used, which is 0.59 for this model. The second is the DOE test's daily hot-water draw for the medium pattern. That pattern stands for a typical mid-sized household on a busy morning. A home that draws more or less hot water than the test will use a different amount of gas. How large that difference would be for any single home is not available from the registry. The steps behind the figure are set out in how the annual energy and cost are calculated.

The registry lists a first hour rating, the gallons of hot water available in the first hour from a full tank, of 57 gallons. The rated volume is 38 gallons. The energy figure fits a household whose daily use is close to the medium draw pattern. A household whose morning peak regularly goes past 57 gallons is outside what this rating describes. For energy use, the model ranks 186th lowest of 288 in its class. Its figure is above the class median, so a reader looking for lower gas use can compare other models of the same class. The same-class replacement search by model number lists those models.

The running cost is not stated in this text because it depends on your own gas rate. The page multiplies the 188 therms figure by your state's average residential gas price, taken from your ZIP code. The 3 therms gap above the class median is priced at the same rate. So its cost changes with where you live and cannot be stated here. You can enter a ZIP in the water heater cost calculator for your own ZIP. The installed price shown in its own block on this page is a modeled range with its own source and date. It is not a quote for this model.
