JETGLAS RG1PV50S*N19

The figure of 245 therms is computed by this site, not published by the registry. It combines the registry's UEF, the ratio of hot water delivered to energy used, of 0.69 with the DOE test's daily hot-water draw for the high draw pattern. The result applies to natural gas at that draw only, and the source data was retrieved from DOE CCD on 2026-09-19. A household whose real hot-water use differs from the test draw will use a different amount, and this page holds no measurement of that. The derivation is described under how the annual cost is calculated.

The rank of 130th lowest among the 414 comparable models places this unit in the second-lowest quarter of its class for energy use. The gap to the median of 260 therms is 15 therms, measured in therms at the same draw, so it says nothing about hot-water capacity. Capacity is shown by the first hour rating, the gallons of hot water available in the first hour from a full tank. For this model it is 78 gallons, with a rated volume of 48 gallons. The high draw pattern describes a larger household, or one where showers and laundry overlap. Energy figures for lower draw patterns are not available for this model on this page. To compare other fuels, spaces and sizes, use the water heater selector.

The running cost is not written here because it depends on the state average residential gas price, which differs by reader. The 245 therms figure is the fixed input, and the price multiplies it. The same rate also sets what the 15 therms gap to the class median of 260 therms is worth, so that gap is not a cost figure. Enter your ZIP in the cost calculator to apply the price for your state. The modeled installed-cost range appears in its own block with its source and date, and it is a modeled range, not a quote.
