Richmond PRO+G50-47P RH62 PDV

This site computes the 260 therms figure; the registry does not publish it. The calculation 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 high draw pattern. For this model the UEF is 0.65, from DOE CCD data retrieved 2026-09-19. The figure holds only at that test draw. A household that draws more or less hot water than the test will use a different amount of gas, and that amount is not available from the registry data. Among the 414 gas tank models at the high draw pattern, this one ranks 204th lowest energy use. The steps behind the figure are set out in how the annual cost is calculated.

The high draw pattern represents a larger household, or one where showers and laundry overlap. This model's first hour rating, the gallons of hot water available in the first hour from a full tank, is 81 gallons. Its rated volume is 48 gallons. A home whose busiest hour needs more than 81 gallons of hot water needs more than this rating covers. A home with a smaller daily draw than the high draw pattern falls outside the test conditions, so the 260 therms figure does not describe its gas use. The registry data does not show how much less such a home would use. To compare other gas tank models by size, use the selector by fuel, space and size.

The text on this page gives no running cost. The cost of 260 therms of natural gas a year depends on your state's average residential gas price. The page therefore computes it from your ZIP. Enter your ZIP in the cost calculator on your own ZIP to see the figure for this model at the high draw pattern. The installed-cost range appears in its own block, with its source and date. It is a modeled range, not a quote. If you are checking a replacement for this unit, the tool to find a same-class replacement by model number lists other gas tank models registered at the high draw pattern.
