Rheem CRHBH-L99i ThermaForce Super High-Efficiency Condensing Boiler is engineered to deliver reliable residential heating while maximizing energy efficiency.
With efficiency ratings up to 96% AFUE, this condensing boiler helps homeowners lower heating costs and reduce fuel waste. ENERGY STAR® certification confirms its high-performance efficiency standards and supports lower long-term utility costs.
The integrated outdoor reset technology automatically adjusts heating water temperatures based on outdoor conditions, helping improve comfort and optimize seasonal efficiency.
At the heart of the ThermaForce® boiler system is Rheem’s patented single-pass Labyrinth Heat Exchanger with integrated copper waterways.
This advanced heat exchanger design is engineered to maximize heat transfer while minimizing heat loss, helping improve thermal performance and operational reliability. The condensing technology captures more usable heat from combustion gases, increasing overall system efficiency.
The integrated copper waterways also support long-term durability and consistent heating performance in residential applications.
Rheem CRHBH-L99i ThermaForce Super High-Efficiency Condensing Boiler features an illuminated touchscreen control panel that simplifies diagnostics, system monitoring, and operational setup.
For larger heating applications, the system supports wireless cascading through RF communication, allowing up to 8 boilers to work together without requiring Wi-Fi. Cascading technology helps balance workloads across systems to reduce wear and extend equipment life.
The built-in ECM variable speed pump further improves efficiency by automatically adjusting flow rates to match heating demand.
CRHBH-L99i is designed for installation flexibility and simplified long-term maintenance.
Installation and servicing advantages include:
The simplified mechanical design helps reduce servicing complexity while supporting dependable long-term operation.
Unlike combi boilers, Rheem CRHBH-L99i ThermaForce Super High-Efficiency Condensing Boiler is designed primarily for hydronic heating but can connect to an indirect tank to provide domestic hot water.
This allows homeowners to create a customized whole-home comfort system capable of supporting radiant heating, hydronic heating zones, and hot water storage solutions.
With a compact wall-mounted footprint measuring only 32.5″ high, 17.69″ wide, and 10.88″ deep, the CRHBH-L99i is ideal for basements, utility rooms, mechanical closets, and retrofit heating installations where space efficiency matters.
