What is a Vaillant boiler warranty?

A Vaillant boiler warranty serves as a written guarantee where a boiler manufacturer agrees to repair damages or replace parts as long as it is within its terms and conditions.

When the problem is beyond repair or the cost of repair is more than the amount of the unit, a boiler replacement may be issued. This will provide you with a new Vaillant boiler for your heating system!

However, a boiler guarantee will not cover all damages and defects even when it is still within the warranty period. You must be aware of the limitations and exclusions set by the boiler brand.

Additionally, an extended guarantee may be given depending on some factors. This will lengthen the duration of your boiler’s warranty period.

How long does a Vaillant boiler warranty last?

The central heating system of a home plays an integral role in the comfort of a home, especially during the colder months. A functioning heating system is not just a want but a need to live comfortably.

Since a boiler is an expensive purchase, you want to be protected from unnecessary repair and labour costs from damages beyond your control. After a Vaillant gas boiler installation, you will be eligible for a warranty.

Terms and conditions of a Vaillant boiler warranty

vaillant boiler

Vaillant carries a wide range of boiler types under its brand for both domestic and commercial structures.

Depending on your needs, you can choose from a combi boiler or a system boiler. Warranties cover all types of boiler service and boiler repair.

But, as with all agreements between a purchaser and a manufacturer, there are conditions for these warranties to be valid and used.

For a Vaillant boiler warranty, the following terms and conditions apply:

  • Register the boiler within 30 days of installation to get the standard warranty time. Doing so guarantees that Vaillant boiler engineers can come to your rescue should something go awry with your boiler. Failure to register within 30 days will lessen the duration of warranty coverage to 12 months.
  • A Gas Safe registered engineer must install and commission a Vaillant boiler within 6 months from the boiler’s manufacturing date.
  • The engineer must follow all installation instructions from the manual that comes with the boiler. They should also complete the Benchmark log book and leave it to the homeowner for future use during a warranty claim.
  • The launch of the Vaillant boiler warranty period is on the installation date if there is an invoice or completed Benchmark log book. Without these documents, the warranty date will be based on the boiler’s manufacturing date.
  • Annual Vaillant boiler service must be done by a Vaillant or Gas Safe registered engineer. Failure to do so might render the boiler warranty invalid. This warranty doesn’t cover the cost of the annual service.
  • The warranty only covers problems within the boiler from manufacturing defects. Materials and labour costs may be free of charge if the repair is made by a Vaillant or Vaillant-authorised Gas Safe registered engineer.
