Comfort E XL

SONNENKRAFT’s® COMFORT E XL system guarantees maximum solar yield for large-scale systems.


  • Approx. 30 – 70 % coverage of water heating
  • Ideally suited for integration of solar swimming pool heating and / or backup heating
  • Highly efficient strata charging of the backup tank by means of premounted stratified charging module
  • Areas of application are many, such as tourism, hospitals and care facilities as well as public buildings


Use In New Constructions

  • Fresh, hygienic hot water through continuous water heating (fresh water module)
  • Prevention of infections or legionella formation in the drinking water heating system


Retrofitting Application

  • optimal solar energy use through continuous water heating (pre-heating phase)
  • low conversion costs through simple integration into existing systems without the typical boiler expansion
  • Higher efficiency than with hot water tank preheating systems
