Richmond PROG29-32N RH63 *

The 185 therms figure is calculated by this site, not taken from 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 for the medium draw pattern. This model's UEF is 0.6. The medium pattern stands for a typical household load on the federal test, not for any particular home. A home that draws more hot water each day will use more gas than 185 therms, and one that draws less will use less. The UEF comes from the DOE CCD, retrieved 2026-09-19. The steps behind the figure are set out in how the annual cost is calculated.

The class for this model is the 288 models registered as a gas tank at the medium draw pattern. In that class it ranks 89th for lowest energy use of 288. That places it in the second-lowest quarter of its class for energy use. Its first hour rating, the gallons of hot water available in the first hour from a full tank, is 63 gallons, from a rated volume of 28 gallons. These figures are useful for checking this unit against other medium-pattern gas tanks. They do not support a comparison with electric, heat pump or tankless units, because those are registered in other classes. To see models in the same class, use find a same-class replacement by model number.

This text does not state a running cost. The cost of 185 therms of natural gas depends on your state's average residential gas price, so the page calculates it from your ZIP. The same annual energy use can cost a different amount in each state. You can get that figure from the cost calculator on your own ZIP. This page does not publish an installed price range for this model. Its ratings lie outside the range the cost database's model was fitted on, and the site does not extend that range beyond its fitted limits. The installed price of the Richmond PROG29-32N RH63 * is therefore not available here.
