Rheem RTGH-SR11i – 11.0 GPM Indoor High-Efficiency Condensing Tankless Water Heater with Recirculation Pump
The Rheem RTGH-SR11i is a high-efficiency, condensing tankless water heater designed for commercial-grade performance in residential or light-duty commercial applications. This model delivers a maximum flow rate of 11.0 gallons per minute at a 35°F rise and is equipped with an integrated recirculation pump to minimize hot water delivery times across the distribution system.
This unit operates on either natural gas or liquid propane and is intended for indoor wall-mounted installations. Featuring stainless steel condensing heat exchangers, commercial-grade components, and built-in WiFi for remote monitoring, the RTGH-SR11i provides a solution for applications requiring consistent hot water with reduced standby losses.
Product Highlights
- Condensing Technology: Dual stainless steel heat exchangers recover additional energy from exhaust gases, increasing system efficiency.
- Recirculation Pump: Built-in recirculation reduces wait times and supports dedicated return lines or crossover valve configurations (Smart-Circ™ ready).
