Rheem Broadens Hydronics Boiler Offerings with Heating and Hot Water Solutions
Expansion includes new boiler, combi boiler and high-performance indirect tank solutions.
Rheem has announced an expansion of its hydronics portfolio. The addition includes three product offerings: the Rheem FT Series Combi Boiler, Rheem FT Series boiler high-capacity models and new Rheem STID Indirect Tank MAX models.
Building on the launch of the Rheem FT Series Boiler platform in 2025, the new offerings feature higher output and enhanced hot water performance to provide more options and meet the growing demand for larger residential and light commercial applications.
"High efficiency hydronic heating is undergoing rapid change, and we anticipate continued growth in the market,” said Patrick McLaughlin, Hydronics Product Manager. “Rheem is providing a more complete portfolio to help contractors serve a wider range of applications while combining comfort and powerful performance with a user-friendly design for both homeowners and contractors."
The new Rheem FT Series Combi Boiler is an ENERGY STAR certified, super high-efficiency condensing gas solution that combines space heating and continuous domestic hot water delivery in a compact, 2-in-1 design. Engineered with contractors in mind, the unit features a pre-installed boiler pump to reduce installation time and costs, while the integrated combi block enables domestic hot water production, allowing a single appliance to provide both space heating and hot water. Other features include full-color touchscreen control, a stainless-steel fire tube heat exchanger, and efficiencies up to 95% AFUE.
The ENERGY STAR certified, Rheem FT Series boiler high-capacity 260k and 399k BTU/hr models extend the FT Series into higher-output applications for light commercial solutions. The units feature a 10:1 turndown ratio and cascade capability to control up to 24 boilers. The heat exchanger in the Rheem FT Series Combi Boiler and the Rheem FT Series boiler high-capacity models are backed by a 15-year warranty.
The Rheem STID Indirect Tank MAX models are part of Rheem’s stainless steel indirect water heater line, delivering a high-performance domestic hot water solution when paired with high-efficiency boilers. Available in 80- and 119-gallon capacities, these models are designed for larger homes and light commercial applications. Using a high-capacity heat exchanger coil, the STID 80 MAX model provides up to 70% greater first-hour delivery and up to nearly 90% more continuous hot water output than the standard STID 80 model, based on engineering specifications.* The durable stainless-steel tank is backed by a lifetime limited warranty.
The Rheem FT Series Combi Boiler, Rheem FT Series boiler high-capacity models and new Rheem STID Indirect Tank MAX models are available now through Rheem's network of wholesale distributors across the U.S. and Canada.
