Richmond PROG40-30P RH62 DV

This site calculates the 191 therms figure; the registry does not publish it. The model's UEF, the ratio of hot water delivered to energy used, is 0.58 in the DOE Compliance Certification Database, retrieved 2026-09-19. This site combines that UEF with the DOE test's daily hot-water draw for the medium draw pattern. That draw pattern represents a typical family household with a busy morning of hot-water use. Within its class, the model ranks 231st lowest energy use of 288, so most gas tank models at this draw pattern use less gas in the same test. A household that uses more or less hot water than the test assumes will use a different amount of gas, and that amount is not available here. The page on how the annual energy figure is calculated sets out each step.

The model's first hour rating, the gallons of hot water available in the first hour from a full tank, is 58 gallons. Its rated volume is 38 gallons. The registry lists it at the medium draw pattern, so the energy figure above applies to households with about that level of use. A home whose busiest hour needs more than 58 gallons of hot water needs more than this rating covers. A home that wants lower gas use at this draw pattern can compare it with the other models in its class of 288, given the rank above. The selector by fuel, space and size filters that class. A same-class replacement search by model number can start from PROG40-30P RH62 DV.

This text gives no running cost because the cost of 191 therms a year depends on your state's average residential gas price. The page calculates that cost from your ZIP instead, using the same medium draw pattern. The cost calculator on your own ZIP repeats the calculation with your local rate. Because this unit uses 6 therms more than its class median, at any given gas rate it costs more to run than the median model. The difference equals the cost of that extra gas at your rate. The installed-cost range shown in its own block is a modeled range with its own source and date, not a quote. The cost to install this unit at a specific address is not available here.
