Viessmann Boiler Warranty 2021

What is a boiler warranty?

Wouldn't it be nice to know that if your boiler stops working one cold wintry day, you can count on the manufacturer to send an engineer to your home and fix the fault? Boiler warranties are important for this very reason.

A warranty period will tend to last between 1-10 years from the day of installation, depending on the manufacturer and model. While you're in the warranty period, the manufacturer will send an engineer to your home whenever there's an issue to leave you with a functioning boiler.

Sometimes, it's sadly not as simple as that though. So, we've gone through the terms and conditions and taken a magnifying glass to the small print so you don't have to. With our complete guide to Viessmann warranties, you'll find the perfect warranty to you and your home.

Who are Viessmann?

Founded in 1917, Viessmann is a family-owned company that has grown to have over 12,000 employees in countries all around the world. They're one of the leading international manufacturers of systems for heating, industrial energy and cooling, committed to the highest standard of manufacturing. Find out even more, on our Viessmann page.

Standard Viessmann warranty

Viessmann gas boilers come with a 3-5 year parts and labour warranty, as standard. Meanwhile, their oil system boilers have a 2 year standard warranty.

How to extend the warranty

The warranty attached to Viessmann boilers can be extended to as long as 12 years (depending on the range) when certain conditions are met. To benefit from the longest possible warranty, Viessmann typically state that the installation must be performed by a Viessmann Trained Installer.

What's covered by the warranty?

During the warranty period of Viessmann products, they will fix or replace any manufacturing or material defects free of charge.

Terms and conditions

During the warranty period, Viessmann will repair or replace any boiler parts that have been manufactured by themselves, and are proved to be defective in material or workmanship. The warranty doesn't cover any corrosion or deposits, including water corrosion and water borne deposits.

To keep your warranty vaild, you will need to arrange an annual service for your Viessmann boiler.

How to register your warranty

You will need to register the warranty online, via the Viessmann website, which you'll need some personal details for and also details of the boiler, so keep them to hand.
