The SONNENTANK is suitable for hot water preparation and heating support in one to two-family houses. Optimal results are achieved in combination with heat pumps, solar, pellet and biomass systems or the solar power module SONNENKRAFTWERK. This allows the self-consumption share to be increased up to 100%.

ENERGY STORAGE WITH A SYSTEM
The production of renewable energy is weather dependent. The excess energy can only be used at a later point in time with energy storage systems. Here the SONNENTANK system storage system offers the most cost-effective and, at the same time, most hygienic solution. The built-in fresh water station heats the required hot water exactly when it is drawn off, thus avoiding the dangerous formation of legionella in the storage tank. System storage is the smartest way to store energy.

EVEN MORE PERFORMANCE WITH OUR SUNBOOSTER
If you want to bring the energy produced into your storage system even more quickly, you can opt for the system expansion with the SONNENBOOSTER and the solar power module SONNENKRAFTWERK. The highly efficient heat collectors from SONNENKRAFT finally complete the storage system – for 100% use of your own energy.
