Bradford White RTG-K-199N1
Bradford White RTG-K-199N1 is in the DOE listing as of Oct 26, 2026 and is in the ENERGY STAR list as of Oct 26, 2026.
It has a certified UEF of 0.95 and a certified flow of 5.4 gal/min at a 67°F rise.
Its certified flow is 5.4 gal/min at a 67°F rise, while SupplyHouse advertises 8.7 gal/min at a 45°F rise (Archived copy, Nov 12, 2024), so the two figures are not at the same rise.

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 5.2 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 heats 5.4 gallons per minute of water by 67°F in the test. The median gas tankless model heats 4.8 gallons per minute by 67°F. Among 487 gas tankless models, 100 give more flow at a 67°F rise.
The single model number sold under it is ENERGY STAR certified. In tests, 95% of the energy it uses ends up as hot water (UEF 0.95). In the test, daily hot water use was set to high (its draw pattern). Among 399 gas tankless models on its draw pattern, 49 have a higher UEF. A UEF of 0.93 is the median for its type and draw pattern. When it runs, 100% of the energy it uses reaches the water (its recovery efficiency).
All of its test figures are shared by 3 other basic models. The Bosch brand lists one or more of them.
It may qualify for 6 rebate programs in 7 states. It may qualify for 2 more if it meets terms its figures do not show.
