Flow where you live

Colder incoming water needs a bigger rise, so the heater gives less flow.

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 5.5 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 5.7 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. Among 487 gas tankless models, 60 give more flow at a 67°F rise.

Its single model number, JSG52-32PCH/199KWP, is ENERGY STAR certified. In tests, 95% of the energy it uses ends up as hot water (UEF 0.95). Its test simulated a day of high hot water use (its draw pattern). Among 399 gas tankless models on its draw pattern, 49 have a higher UEF. On its draw pattern, the median gas tankless UEF is 0.93. While it heats water, 99% of the energy used goes into the water (its recovery efficiency).

Its test figures match those of 15 other basic models. Besides this brand, 4 brands list one or more of them. You can find the whole group on the page for the Elios EROD199N0000.
