Buffer tanks are essential components in heating, cooling, and hot water systems. They serve as reservoirs to balance the flow of water or other fluids in HVAC systems, helping to maintain temperature stability and reduce energy consumption. By allowing the system to run smoothly, buffer tanks prevent rapid cycling of the HVAC equipment, enhancing the longevity of pumps, compressors, and boilers. These tanks are commonly used in both commercial and industrial applications, including chilled water systems, hydronic heating systems, and geothermal or solar water heating systems.
