Ensun-Buffer Tank Manufacturer in China
The buffer tanks play the role of keeping a minimum water volume in situations where there is a very low heating load. This function prevents short cycling of the heat pump and sustains the minimum flow rate along the heat pump.

The expansion tank provides head pressure to a circulation pump while a buffer tank helps prevent short cycling and adds volume to the system.
Buffer tanks are mainly divided into two types, the “Hot Water Buffer Tanks” and “Chilled Water Buffer Tanks”.

Working Principle
The buffer tank’s primary function is to decrease cycling heat. Other than that, its other operation is for thermal energy storage. This tank can hold enough heated water and runs it through the hydronic system.
As a thermal energy storage, it is possible since they used the tank to generate heating. This heat is usable for later usage. Additionally, the buffer tank’s efficiency in storing enables balanced cycling requirements for alternate turns. The process of reducing the cycling frequency cuts regular costs.
Why Choose Buffer Tanks
Here are some benefits of using buffer tanks that might be appropriate for optimization
-
Ensures absolute efficiency of flowing
The structure of buffer tanks has an excellent circulation system for water and gas. Waters discharge from the lower part and release gas in the upper portion with pressure. Therefore, the role of the buffer tanks improves the risk of malfunctions and flowing.
-
Prevents typical system issues
On the bottoms of the buffer tanks, impurities from the water source are retained. It avoids creating a problem for the internal pipework that might impair performance.
-
Minimizes compressor damage
Without buffer tanks, the compressors continue to alternate, switching on and off when temperatures rise, impairing their lifespan.
