Thermal stratification ensures maximum energy savings
The charging and discharging behavior of the storage tank is decisive for the efficiency of a heating system. For this reason, Sailer stratified storage tanks are stratified by the stratification cones according to the temperature level (hot at the top, warm in the middle, cold at the bottom) without mechanical or electrical aids, which saves a great deal of energy. This stratified cone technology enables savings of up to 60% in primary energy.

Stratified storage tank - Maximum energy efficiency saves costs in the long term
Stratified storage tanks with Sailer stratification ensure the greatest possible energy efficiency for heat storage and hot water preparation.
Thermal stratification ensures the greatest possible energy savings
The charging and discharging behavior of the storage tank is decisive for the efficiency of a heating system. For this reason, Sailer stratified storage cylinders stratify the heat through the stratified cones according to the temperature level (hot at the top, warm in the middle, cold at the bottom) without any mechanical or electrical aids, which saves a great deal of energy. Sailer stratified cone technology enables savings of up to 60% in primary energy.
Stratification without mechanically moving parts Sailer stratification loaders work without mechanically moving parts, such as membrane flaps. This means that the stratification loaders are completely maintenance-free.
Stepless stratification The many outlet openings on the stratified loader are evenly distributed over its entire height. This allows stepless stratification into the appropriate storage layer.
Horizontal 360° stratification The outlet openings extend around the entire circumference of the stratified loader. This results in a large flow cross-section, which ensures a very smooth inflow. Furthermore, the layering elements are designed in such a way that the inflow is horizontal. This horizontal 360° layering prevents turbulence and thus unwanted mixing.
Stratification quality remains stable The stratification charging device is designed in such a way that no water can penetrate from the storage chamber into the stratification charging device in the event of density differences between the storage chamber and the stratification device. This ensures that the stratification quality remains stable.
Most efficient heat storage Optimum stratification enables thermal energy to be stored with maximum efficiency. The temperature level provided by the heat generator is stratified almost loss-free and can be used again later by the consumers.
Stratified charging units adapted to the heat generator Different stratified charging units are available depending on the type and output of the heat generator.
Optimum size and division of the storage areas for each heat generator and consumer Various storage types and sizes are available as standard. These have been designed for standard applications and differ essentially in the division of the storage areas and the equipment of stratified charging devices.
Optional: Integrated heat exchanger with stratified charging device for solar The Sailer stratified charging device is also used for solar charging. Even with low solar radiation, the solar energy can be stratified in the cylinder for use.
How a stratified storage tank works

How does a stratified storage tank work?
A stratified storage cylinder, also known as a stratified charging cylinder, works by efficiently storing and utilizing thermal energy in different temperature layers. The stratified cylinder function is based on the natural layering of water, which has different densities depending on the temperature. Warmer water is kept at the top of the cylinder, while cooler water remains at the bottom. This stratification enables optimized use of energy, as exactly the amount of hot water that is needed at any given time is extracted. This minimizes energy consumption and maximizes efficiency. A stratified cylinder is particularly advantageous for heating systems and hot water preparation systems, as it ensures a constant and reliable heat supply.

What are the advantages of a stratified storage tank?
A stratified cylinder offers several advantages. It maximizes the efficiency of heat storage by using different temperature zones in the cylinder. This makes optimum use of the energy and minimizes losses. The stratified cylinder function enables hot water to be provided quickly, as the different layers can be addressed in a targeted manner. A stratified cylinder can also facilitate the integration of renewable energies such as solar thermal energy. The flexible storage technology ensures better adaptation to individual heating requirements and can lead to cost savings. Overall, a stratified storage tank improves energy use and contributes to sustainable energy management.
When is a stratified storage tank worthwhile?
A stratified storage cylinder is particularly worthwhile in households that rely on renewable energies such as solar thermal energy. This type of cylinder can efficiently store excess heat and release it when required. As a result, the energy is used optimally and heating costs can be reduced. A stratified cylinder can also be advantageous in buildings with a high heat requirement or variable heat demand, as it distributes the heat evenly. If you also value sustainability and energy efficiency, a stratified cylinder could be the right choice.
Which is better, stratified storage or buffer storage?
A stratified cylinder is a specialized form of buffer cylinder. Both types can store thermal energy in the same way, but a stratified cylinder is much more efficient in the way it works. The decision between a stratified cylinder and a buffer cylinder depends on your individual requirements. A stratified cylinder offers the advantage of optimum temperature stratification, which leads to more efficient use of the stored energy. This means that you have faster access to hot water, which can be particularly beneficial in households with high hot water requirements.
Consider your specific hot water supply requirements and existing heating technology to make the best choice. A professional can help you choose the right option for you.
