Boiler Economizers | CBW Industrial Boiler Waste Heat

Studies have shown that over a 20 year period, 96% of the cost of operating a boiler system comes from fuel costs. 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
