Although technically a separate catalogue, Viessmann now integrates boilers with heat pumps digitally. Look for the Vitocal 200-S (Air/Water) or Vitocal 300-G (Brine/Water ground source).
The catalogue dedicates a section to the Vitosol-F flat plate collectors. These connect to a Vitocell DHW cylinder to pre-heat water for the boiler, reducing gas consumption by up to 30% annually. viessmann boiler catalogue
