The heater gives less flow when colder incoming water needs a bigger rise.
- Cold water
- Cold water must be at least 10°F colder than the hot water setting.
- Flow estimate
- The estimate uses the lowest certified flow among the listed models. It is about 5.6 gal/min at a 70°F rise.
Flow limits
- The estimate excludes the flow needed to turn the heater on, heat lost in pipes, and installation.
- Cold water from a well or long pipe run can differ from the temperature you enter.
- Without a stated flow limit, estimates for warmer water may exceed the heater’s actual flow.
Certified figures by listed model

UEF is the uniform energy factor. A dash means the model has no such figure.
At a 67°F rise, its flow in the test is 5.8 gallons per minute. The gas tankless type has a median flow of 4.8 gallons per minute. Its flow at a 67°F rise trails 26 of the 487 gas tankless models.
As of Oct 19, 2026, it was not listed as ENERGY STAR certified. In tests, 98% of the energy went to hot water, so its UEF is 0.98. The daily hot water use in the test, called its draw pattern, was high. No other gas tankless model among the 399 on its draw pattern has a higher UEF. On its draw pattern, the median gas tankless UEF is 0.93. While it heats water, 100% of the energy used goes into the water (its recovery efficiency).
It is sold under 4 model numbers in all. There are 3 more basic models with the same test figures. Those basic models are sold with CAMPLUX, GASLAND, and JUNSKY as their brand names. You can find the whole group on the page for the CAMPLUX JSG53-32PCH-A2-NG.
