Change your hour and flowFlow 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 5.6 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
| Model number | UEF | Flow at a 67°F rise (gal/min) | Recovery efficiency | Draw pattern |
|---|---|---|---|---|
| RP*199iB | 0.98 | 5.8 | 100% | High |
| RP*199iP | 0.98 | 5.8 | 100% | High |

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 median gas tankless model heats 4.8 gallons per minute by 67°F. Its flow at a 67°F rise trails 26 of the 487 gas tankless models.
On Oct 19, 2026, this heater was not listed as ENERGY STAR certified. In tests, 98% of the energy it uses ends up as hot water (UEF 0.98). Its test simulated a day of high hot water use (its draw pattern). 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. Of the energy it spends heating water, 100% ends up in it (its recovery efficiency).
It is sold under 4 model numbers in all. Its test figures match those of 3 other basic models. Of those, one or more are under the CAMPLUX, GASLAND, and ThermoMate brands. For the full group, see the CAMPLUX JSG53-32PCH-A2-NG page.
It may qualify for 2 rebate programs. It may qualify for 2 more if it meets terms its figures do not show.
