Bosch T-9900 160k BTU Residential Indoor Tankless Water Heater

The Bosch T-9900 160k BTU Residential Indoor Tankless Water Heater is a Bosch Greentherm T9900 SE indoor condensing tankless water heater sized at 160,000 BTU/hr. It is built for efficient residential hot water service where the installation needs the T9900 platform but not the larger 199k firing rate.

The T9900 SE 160 shares Bosch’s condensing construction, low-NOx combustion certification, CSA/ANSI listing, and modulating gas control platform. Its 160k rating is useful for tighter sizing, smaller households, or applications where gas supply and demand calculations do not justify a 199k heater.

Product Features:

• 160,000 BTU/hr Input: Lower-output T9900 SE capacity for correctly sized residential applications.
• T9900 SE Platform: Uses Bosch’s SE indoor condensing gas tankless architecture.
• Gas-Fired Condensing Design: Submittal describes a gas-fired condensing tankless design.
• Natural/Propane Fuel Capability: Bosch identifies both fuel options for the 160/199 T9900 SE platform.
• Lower Gas Demand Than 199k: Useful where fixture load calculations support 160k sizing.
• CSA/ANSI Certified: Listed to CSA/ANSI Z21.10.3 per Bosch engineering submittal.
• Low-NOx Certified Burner: Documented to meet 2016 SCAQMD NOx Rule 1146.2.
