BEI Indirect Contact Water and Heat Recovery


​The most modern steam boiler economizers available.

In June 2018 Thermal Energy International acquired Boilerroom Equipment Inc (BEI). Founded in 2005 and based outside of Pittsburgh PA, BEI engineers and manufactures indirect contact heat recovery equipment for many different industries. They are best known as the innovators behind the HeatSponge brand of boiler economizers. BEI also engineers and fabricates wet and dry steam accumulators
​
​BEI’s Heat-Sponge SIDEKICK and RAINMAKER product line is the first boiler economizer specifically designed for hot water boilers. Prior to the advent of the Sidekick and Rainmaker the only option for owners of older, less efficient boilers was to demolish them and purchase newer boilers.  
 
Unlike steam boilers, that have utilized economizers for over a century, hot water boilers handle significantly higher water flow rates requiring the design of this first-to-market heat exchanger.
 
The Sidekick excels when used to retrofit conventional efficiency boilers into condensing boilers often for less than a third the installed cost of a new condensing boiler.

​Any size boiler is a candidate for a Sidekick or Rainmaker, with the majority of the return on investment coming in under three years.

The key benefits are:
  • Easy to procure, install, and operate
  • Converts conventional boilers to condensing efficiencies
  • Full stainless steel construction
  • Retrofit existing or new installations at substantially reduced cost
  • Eliminates the need to demolish and replace existing non-condensing boilers
  • Units are designed to provide for high performance heat recovery
  • Designed for small and large industrial, commercial and institutional sectors
  • The industry's only repairable coiled economizer
  • Steam boiler economizers from 20 HP to 250,000 pph
  • Hot water boiler economizers from 500 mbtu to 50 mbtu pph
  • Conventional and condensing models
