Boilerroom Equipment, Inc. (BEI), a division of Thermal Energy International, is the engineering force behind the HeatSponge line of high-value-added conventional and condensing boiler economizers. 

HeatSponge steam boiler economizers represent the global state-of-the-art in industrial heat recovery. Engineered from the ground up for maximum efficiency, durability, and ease of maintenance, these systems deliver long service life and outstanding performance. The Two-Stage HeatSponge integrates two separate heat exchangers within a single casing, pushing steam boiler efficiencies beyond 90%. BEI’s proprietary Type III multi-pass multi-stage designs further extend this innovation, capturing every available heat sink to deliver the highest possible gains in boiler efficiency.

BEI is also widely recognized for its proprietary software platform, Bruce—the industry’s most advanced engineering and estimating tool. Developed entirely in-house by the company’s founder, Bruce generates fully engineered and priced proposal packages in real time via the internet, streamlining the sales and design process like no other tool in the industry.

When was the last time a product changed an entire industry? 

BEI pioneered the concept of external secondary condensing heat recovery for hot water boilers, introducing breakthrough technologies that allow both new and existing conventional-efficiency boilers to achieve condensing-level performance—without the limitations of integrated condensing systems. Notably, the HeatSponge Rainmaker lines enable full condensing performance while maintaining compatibility with standby oil operation.

BEI’s Rainmaker product lines represent that shift—a revolutionary external condensing economizer that renders most conventional condensing boilers obsolete. Designed for both new installations and retrofits, these systems deliver condensing-level efficiencies at a significantly lower cost.
