A Waste Heat Recovery Tank is a specialized thermal storage vessel designed to capture and utilize heat that would otherwise be lost from waste streams in industrial or commercial processes. In many systems, waste heat exists in exhaust gases, hot water discharge, or cooling circuits, and this energy can be transferred to a tank where it is stored and later used for water preheating or space heating. Waste heat recovery tanks typically incorporate heat exchangers or coils that absorb thermal energy from high temperature sources and transfer it to the tank’s water or thermal medium, reducing the load on primary heaters and improving overall system efficiency. By recycling latent heat that would otherwise be dissipated to the environment, such tanks help lower energy consumption, reduce fuel costs, and decrease greenhouse gas emissions. They are often integrated into combined heat and power (CHP) or heat recovery systems to maximize energy reuse and sustainability.
