Hydraulic buffer energy storage tank

What is a hydronic buffer tank?

Heat-flo’s Hydronic Buffer Tanks are designed to be used in closed loop heating systems with low-mass boilers, geothermal systems, and chilled water applications. Utilizing our hydronic buffer tanks improves system efficiency and can extend equipment life by reducing the wear and tear on chillers or boilers due to short cycling. HF-22-BT

What is a buffer tank in a heating system?

A buffer tank, also known as a thermal storage tank, is a vessel that holds a volume of water within a heating system. It acts as a reservoir of heat, allowing for the efficient distribution of heat throughout the system.

Do hydronic HVAC systems need a buffer tank?

Buffer tanks play an important role in hydronic HVAC systems, enhancing efficiency and stability, but they are not utilized in every system. Understanding when and why to use a buffer tank is crucial for anyone looking to deepen their knowledge of hydronic HVAC systems.

How do buffer tanks improve equipment efficiency?

They improve equipment efficiency by reducing frequent on/off cycling (short-cycling), which extends the lifespan of the equipment. Buffer tanks provide a “buffer” between the heating or cooling source and the system load to ensure stable temperatures.

What is buffer tank design?

Buffer tank design refers to the process of designing a storage tank that helps regulate and stabilize the flow of fluids, such as water or gas, in a system. It is used to mitigate pressure fluctuations, maintain consistent flow rates, and prevent damage to equipment.

Why is a buffer tank used instead of a thermal storage?

Inadequate Turndown: When equipment can't reduce output capacity to meet the minimum load requirement of a system, it can use the buffer tank’s thermal storage instead. This prevents short cycling by not requiring the equipment to cycle on.
