Guaranteed to feel cosy

With our system warranty

The day is finally here – your new Kermi heating system, or perhaps a Kermi ventilation system, has been installed and there’s now nothing standing in the way of that cosy feeling spreading throughout your home.


Our five-year system warranty is a testament to the quality of our products and our service promise to you.

The statutory warranty is 24 months – but when it comes to creating a feeling of well-being, we don’t think that’s enough. With our five-year system warranty, we provide 60 months of security for Kermi heating and ventilation systems, free of charge. Because trust and security are also an important part of feeling good.


How you benefit:

Reliability thanks to coordinated components from the Kermi x-optimised system

Fast, dependable assistance if you make a warranty claim

More for your money – because there are no additional costs for the five-year system warranty

The secure feeling of having chosen a sustainable, future-proof solution

A contact person for your installed system components

Just three steps to a five-year system warranty

1. Have the Kermi system installed by a specialist company

2. Have Kermi Customer Service commission the system

  • In the case of ventilation systems, a specialist company
  • In the case of heat pumps, a specialist heat pump partner certified by Kermi

3. Have Kermi Customer Service perform regular inspections of the system

  • In the case of ventilation, a specialist partner
  • In the case of heat pumps, an authorised specialist company
