Midea JSG52-32PCH-NG

The figure of 178 therms is not a registry entry. This site computed it from the registry's UEF, the ratio of hot water delivered to energy used, which is 0.95 for this model. It also used the daily hot-water draw that the DOE test assigns to the high draw pattern. The fuel is natural gas, and the source is the DOE CCD, retrieved 2026-09-19. The figure describes the test's daily draw, not your household. Actual gas use will differ with real hot-water use, inlet water temperature and settings, and none of those appear in the registry data, so this page does not estimate them.

Among the 397 models registered as a gas tankless unit at the high draw pattern, this one ranks 45th lowest in energy use. That places it in the lowest quarter of its class. The class median is 182 therms, and this model sits 4 therms below it. The gap describes position within the class, not savings for any particular home. The high draw pattern fits a larger household, or one where showers and laundry overlap. The maximum flow rate in gallons per minute is 5.7. The registry data does not show whether that rating covers the simultaneous use in a specific home.

A household with lighter hot-water use falls under a different draw pattern, and the 178 therms figure does not apply to it. A figure for this model at other draw patterns is not available on this page. Running cost is not stated because it depends on your state's average residential gas price. The cost calculator applies that price from your ZIP to 178 therms, and the page on how the annual cost is calculated describes the method. To compare by fuel, space and size, use the water heater selector. To look for a same-class alternative to JSG52-32PCH-NG, you can find a replacement by model number. The modeled installed-cost range appears in its own block on this page, with its source and date.
