The heat store is one of the key components of a heat pump that is used to store heat. The stored heat is then fed to different consumers depending on the needs of the heating system. The storage tank allows the heat pump to operate more efficiently, stably and flexibly, leading to reduced wear and tear, extended plant life and reduced energy consumption.
A storage tank, powered by a heat pump, is used to store a heated or cooled liquid as a heat transfer medium. This storage tank also provides a hydraulic damper function, which reduces the frequency of switching the heat pump on and off, thereby increasing its efficiency and lifetime. In addition, it enables the hydraulic balancing of the system by distributing the heat load evenly between the different circuits of the heating system.
