Frequently Asked Questions about Hermann Boilers
Is Hermann the same as Saunier Duval or Vaillant?
They are part of the same group (Vaillant), but differentiated brands with their own models. Hermann It is mainly distributed in Italy and part of Spain. The most recent models share the technical platform and many components with equivalent Vaillant and Saunier Duval models, making it easier to locate spare parts.
Are there spare parts for old Hermann boilers?
For models like the Super Micra and Eura Combi manufactured before 2010, some specific spare parts may be difficult to find as originals. However, as they share a platform with equivalent Saunier Duval and Vaillant models, many components (pump, NTC, gas valve, electrode) are interchangeable. Consult us with the model number to confirm availability.
How often should a Hermann boiler be serviced?
Maintenance, regulatory inspection and warranty conditions are different matters. Frequency depends on the equipment, power, use and maintenance manual. The contract identifies included visits and operations; it does not alone equate to a certificate or official inspection.
