The most important things in brief

Increased efficiency: A buffer storage tank optimizes the operation of heating systems by storing excess heat and releasing it when needed.

Energy saving: Reduces the number of burner starts and lowers fuel consumption.

Subsidies: State subsidy programs support the installation of buffer storage in combination with renewable energies.

How does a buffer storage work?

A buffer storage tank stores heat energy and releases it to the heating system as needed.

  • Heat absorption: The excess heat from the heating system or a solar system is stored.
  • Layered storage: Different temperature layers ensure that the heat remains usable for a long time.
  • Demand-based release: The stored heat is released into the system when heating is required.

types of buffer storage
