Richmond PRO+G50S-40N RH67 PD

This site computed the 245 therms figure; the registry does not publish it. 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 high pattern. This model's UEF is 0.69, taken from the DOE CCD, retrieved 2026-09-19. The figure holds only at that test draw. A home that uses more or less hot water will have a different yearly total. Among the 414 gas tank models at the high draw pattern, this unit has the 130th lowest energy use. That puts it 15 therms below the class median of 260 therms. The steps behind the figure are set out in how the annual cost is calculated.

The high draw pattern stands for a larger household, or one where showers and laundry overlap. This unit has a first hour rating, the gallons of hot water available in the first hour from a full tank, of 78 gallons. Its rated volume is 48 gallons. The rating does not cover a home whose busiest hour needs more than 78 gallons of hot water. The 245 therms figure also does not describe a home with lighter use than the high draw pattern, because it assumes the high test draw. This page does not show whether a smaller gas tank would suit that kind of home. The selector by fuel, space and size filters models on those terms.

This text does not state a running cost. The cost depends on your state's average residential gas price, so the page works it out from your ZIP. The input is the 245 therms at the high test draw, and your rate sets the result. To see it, use the cost calculator on your own ZIP. The installed price appears in its own block, with its source and date. It is a modeled range, not a quote.
