Midea JSQ40-20VHUS-NG
0.82 UEF DOE CCD · 2026-09-19Grade G: where this UEF sits among the 80 models in its class, lowest (G) to highest (A). A position, not an official label. How the grade is set
A gas tankless unit, medium draw pattern (a typical three- or four-person household, about 55 gallons on a busy morning).
If you are checking this unit's figures, the Midea JSQ40-20VHUS-NG uses 135 therms of natural gas a year. That is at the medium draw pattern, the standard daily hot-water usage DOE tests against. It equals the class median of 135 therms, a difference of 0 therms.
Energy use per year
135 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 equal to the median of 135 therms for the 80 models registered in the same heater type and draw pattern; it ranks 32 of 80, lowest energy first.
Solid line: this model (135 therms). Dashed line: the class median.

The registry lists a UEF, the ratio of hot water delivered to energy used, of 0.82 for this unit. This site combined that UEF with the daily hot-water draw DOE assigns to the medium draw pattern. The result is 135 therms of natural gas a year. The registry does not publish that figure itself. The maximum flow rate in gallons per minute is 3.7, and it does not enter this calculation. Both inputs are model-level values, so the figure applies to this model number only. The energy source is DOE CCD, retrieved 2026-09-19. The method is set out on the page about how the annual cost is calculated.
Among the 80 models registered as a gas tankless unit at the medium draw pattern, this model has the 32nd lowest energy use. Its 135 therms equals the class median of 135 therms, a difference of 0 therms. The data here does not give the spread of models around that median. The figure suits a household whose hot-water use matches the medium draw pattern, a typical household of several people on a busy morning. It is a weaker guide for a household that draws much more or much less hot water. Energy figures for other draw patterns are not available on this page. The selector by fuel, space and size covers other needs.
The running cost is not stated here because it depends on your state average residential gas price. The cost calculator applies that price, taken from your ZIP, to the 135 therms for this model. The result holds only at the medium draw pattern. Your own hot-water use may differ from the federal test's daily draw, and this site cannot estimate that difference. The installed price range is shown in its own block, with its source and date, as a modeled range and not a quote.
