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
heating buffer storage
Features: Storage of excess heat from boilers or solar systems for space heating.
Advantages: Increased efficiency, avoidance of burner starts, reduction of emissions.

hygiene buffer storage
Features: Combination of buffer tank and hot water tank with integrated heat exchanger.
Advantages: Hygienic drinking water heating, prevention of legionella, efficient operation.

stratified storage
Features: Stores heat in different temperature layers for better efficiency.
Advantages: Reduces heat loss, optimizes energy savings.
advantages and disadvantages
Advantages: Reduced fuel consumption, longer service life of heaters, efficient use of renewable energies.
Disadvantages: Additional space required, acquisition costs.
costs and subsidies
Heating buffer storage: From approx. 1,500 €.
Hygiene buffer storage: From approx. €2,500.
Subsidies: Up to 30% subsidy when combined with renewable energies.
possible uses
Buffer storage tanks are suitable for pellet heating systems, heat pumps and solar systems to increase their efficiency.
