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 4.1 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.

It warms 4.3 gallons per minute of water from 58°F to 125°F in the test. The median gas tankless model heats 4.8 gallons per minute by 67°F. Of 487 gas tankless models, 346 have a higher flow than this one.
The single model number sold under it is ENERGY STAR certified. In tests, 98% of the energy it uses ends up as hot water (UEF 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. A UEF of 0.93 is the median for its type and draw pattern. When it runs, 98% of the energy it uses reaches the water (its recovery efficiency).
Its test figures match those of 4 other basic models. Those basic models are sold with Kiturami and Laars as their brand names. For the full group, see the Bradford White KGWH-150JFN page.
