Viessmann Boiler Catalogue

Crucially, the catalogue demonstrates a pragmatic understanding of the current infrastructure. It offers hybrid systems that combine gas condensing boilers with heat pumps. This approach acknowledges that while the future is electric, the transition must be seamless. By offering hybrid solutions, Viessmann provides a catalogue that caters to the retrofit market—older homes with high heating loads—as well as modern, passive houses.

Ideal for homes with multiple bathrooms, these work with a separate hot water cylinder but house most major components (like the pump and expansion vessel) inside the boiler itself. Viessmann Direct 3. Open Vent (Heat Only) Boilers viessmann boiler catalogue
