The Bosch T-9900 199k BTU Residential Indoor Tankless Water Heater is a Bosch Greentherm T9900 SE indoor condensing gas tankless water heater configured for large residential hot water applications. The 199,000 BTU/hr input gives this SE model the higher-capacity option within the non-i T9900 indoor lineup.
Bosch T9900 SE submittal literature lists the platform as CSA/ANSI Z21.10.3 certified, dual-fuel capable, low-NOx certified, and constructed with a copper primary heat exchanger plus stainless steel secondary condensing heat exchanger. It is best suited for users who need T9900 capacity without the integrated pump/WiFi emphasis of the i model.
Product Features:
- 199,000 BTU/hr T9900 SE Capacity: Higher-output non-i indoor T9900 option for multi-bath residential demand.
- Copper Tube-and-Fin Primary: Bosch lists a multi-pass copper tube and fin primary heat exchanger.
- Stainless Condensing Secondary: Secondary heat exchanger uses multi-pass stainless steel construction.
- Dual-Fuel Capable: Submittal states operation with natural gas or propane fuel.
- Low-NOx Combustion: SCAQMD Rule 1146.2 certification is identified in Bosch engineering data.
- Non-i SE Configuration: Provides T9900 capacity without being the integrated-pump T9900i SE variant.
- Modulating Gas Valve: Gas valve modulates firing rate to match changing hot water demand.

- Defective Product, Atrocious SupportI general contracted an entire house for my family and my $1800 Bosch Greentherm Water Heater has given me more trouble than every other piece of hardware combined.
The device started having miscellaneous errors after a few months and now fails multiple times per day roughly a year later. It can’t even make it through its own “auto-adjust” process - the burner goes out.
I’ve reached out to their technical support after registering the product and called their warranty department. Both are no help at all. They demand that I hire a licensed HVAC contractor to come perform diagnostics on it. Even if I could get a contractor to come do that, why should I pay a dime to troubleshoot? Nothing of the sort is mentioned in their warrant. In my opinion, they’re just trying to weasel out of repairing it.
I would recommend against buying any Bosch product because both the product and service are toilet-worthy.
tl;dr I paid 1800 for a defective unit and now Bosch wants me to pay to diagnose the piece of trash.
p.s. The mobile app also doesn’t work at all.
