Boiler Economizers | CBW Industrial Boiler Waste Heat

Boiler Economizers. Also, in a typical boiler system, 10% to 20% of energy input is lost in the form of heat escaping to the atmosphere. The installation of a boiler economizer helps to solve this problem. An economizer is a unit that captures heat from the stack, and then returns it to a water system.
