Large systems

The system for large solar installations SUNimpact®

The SUNimpact®systems open up new possibilities for solar technology wherever large draw-off volumes must be provided. Benefit from our many years of experience, which we also gained with Germany's currently largest solar hot water system  (800 m²) on the roof of the Südharz hospital in Nordhausen.

• Maximum system efficiency thanks to lowest temperature level for cold-water preheating
• Low-flow technology allows lower pipe cross section in the solar circuit and therefore reduces heat loss
• Additional post-heating of the domestic hot-water storage tank by the buffer storage tank allows optimum use of the available solar energy
• High flow rate of domestic hot-water thanks to downstream hot-water tank
• Quick and easy installation thanks to prefabricated components
• Alternatively used for additional central-heating support
• Easy to retrofit since you can continue to use your existing domestic hot-water storage tank and post-heating equipment
• Excellent price-performance ratio
• Hot-water circulation system is incorporated in an energy-efficient manner
