Midea JSG48-29PCH-NG

0.95 UEF DOE CCD · 2026-09-19
B

Grade B: where this UEF sits among the 397 models in its class, lowest (G) to highest (A). A position, not an official label. How the grade is set

A gas tankless unit, high draw pattern (a larger household, or one where showers and laundry overlap).

If you are checking the Midea JSG48-29PCH-NG against its registry entry: this gas tankless unit uses 178 therms of natural gas a year at the high draw pattern, the standard daily hot-water usage DOE tests against. That is 4 therms below the class median of 182 therms.


Energy use per year

178 therms a year

Computed by this site from the registry's UEF and the federal test's daily hot-water draw for this draw pattern. What it costs depends on the natural gas rate where you live.

That is below the median of 182 therms for the 397 models registered in the same heater type and draw pattern; it ranks 45 of 397, lowest energy first.

This model: 178 therms

What these figures mean

The registry does not state annual energy use for this model. This site computed 178 therms from the registry's UEF, the ratio of hot water delivered to energy used, of 0.95 and the DOE test's daily hot-water draw for the high draw pattern. The figure is for natural gas and comes from the DOE CCD, retrieved 2026-09-19. The comparison group is the 397 models registered as a gas tankless unit at the high draw pattern. Within that group, this model ranks 45th lowest energy use of 397, which places it in the lowest quarter of its class. Its 178 therms sits 4 therms below the class median of 182 therms.

The high draw pattern describes a larger household, or one where showers and laundry overlap, so 178 therms applies to that kind of use and to no other. A household with a different draw would be tested against a different daily volume, and its energy use for this model is not available on this page. The unit's maximum flow rate in gallons per minute is 5.2. The registry data used here does not show whether that flow covers a particular home's simultaneous demand. To compare options by fuel, space and size, use the water heater selector. To match an existing unit, you can find a same-class replacement by model number.

The running cost is not stated here because it depends on your state's average residential gas price, and this page does not estimate it. Multiply the 178 therms by your gas price per unit of gas to get a yearly figure, or let the cost calculator on your own ZIP do it. The 4 therms gap to the class median of 182 therms carries over to cost at whatever rate applies to you. The steps behind the calculation are described in how the annual cost is calculated. The modeled installed-cost range for this model is shown in its own block with its source and date. It is a modeled range, not a quote, and it is not repeated in this text.
