TONGYI Heat Pump Buffer Tank for Efficient Thermal Storage Solutions

In a heat pump system, the buffer tank is an indispensable component. When the heat pump starts or stops, it effectively cushions the flow changes within the system, protecting the heat pump equipment. During heating or cooling processes, it stores excess heat or cold energy and releases it promptly when demand increases, thereby improving the system's response speed and energy efficiency.

Technical Specifications

Product Description

Hydraulic Separation – Solves Flow Conflicts

When the heat pump has a fixed flow rate but distribution circuits have variable flow (due to zone valves closing), the buffer tank decouples the two circuits, ensuring stable operation on both sides.

Compatible with Multiple Heat Sources

Can integrate heat pumps, solar thermal, biomass boilers, gas boilers, and backup electric heaters into a single thermal storage system—ideal for hybrid renewable energy systems.

Thermal Stratification for Maximum Usable Energy

Internal diffusers maintain temperature layering (hot at top, cold at bottom), ensuring that the heat pump always draws from the coldest part of the tank (improving COP) and the distribution system draws from the hottest part.

product advantages

02.Optimize water temperature regulation

2.It can store a certain amount of hot water. When the system's heat demand changes, it can act as a buffer, preventing significant fluctuations in water temperature and ensuring that the heat pump always operates within an efficient and stable temperature range.

The material is mostly made of high-quality stainless steel, which has strong corrosion resistance and extends the service life.
