This is a hot water economizer and is a big preheater for domestic hot water use. This boiler plant serves a large community for heating and domestic hot water use. Domestic hot water is used for showers, washing dishes, laundry, ect, ect, ect…. The cold water supply from the city is routed through the economizer to be pre-heated before it goes through a heat exchanger and then the hot water storage tank. This system saves money because it uses the exhaust gases from the boiler to pre-heat the city water supply which is normally 50 degrees Fahrenheit. The exhaust gases from the boiler would otherwise be vented to the atmosphere and would be considered wasted heat. (more…)

Commercial Boiler Stack Economizer | HVAC Heating

Commercial Boiler Stack Economizer
Commercial Boiler Stack Economizer - This is not a normal commercial boiler stack in this boiler room. It has a bypass stack for a commercial hot water economizer. All boilers have make-up water to make up for water lost in the systems especially for domestic hot water use. An economizer makes things more efficient. In this regard, the economizer utilizes the waste heat. Waste heat that is normally vented into the atmosphere. This system was specially engineered and tested to ensure proper operation of design.  (more…)
