Warmflow Boiler Warranty 2021

What is a boiler warranty?

You purchase a boiler with the vision that it will be heating your home for many years to come. So knowing that the manufacturer is there to correct any issues will give you the peace of mind that if anything goes wrong, you're covered. That's why boiler warranties are important.

Warranty periods tend to be between 1-10 years but can differ from manufacturer to manufacturer and model to model. During the warranty period, the manufacturer will send an engineer to your home to repair any faults, leaving you with a fully functioning boiler.

Warranties, like most things in life, come with terms and conditions that could end up meaning you're not covered for everything you thought you might be. That's why we've put together a complete guide of everything you need to know about Warmflow boiler warranties before making your final decision and purchasing your perfect boiler.

Who are Warmflow?

With 50 years' experience, Warmflow manufactures market-leading heating products at the company's headquarters in Lisburn. The company attributes its success and longevity to 3 key priorities: 'Quality manufacturing, quality sales support and quality back up service.'

Warmflow is the brand that brought the UK and Ireland's first and only AA rated combi oil boiler to market, and now they have gone even further thanks to a market leading patented design that sees the combi boiler moving from AA rated to AAA rated status. You can find out much more about Warmflow on their Boiler Guide page.

Standard Warmflow warranty

In the UK, most Warmflow Agentis boilers include a 2 year warranty as standard, while in Ireland Warmflow boilers include a 1 year warranty. The Agentis Professional range, which is designed to save the installer and homeowner time and money as it comes with over £250 of time-saving components already fitted, includes a 5 year warranty as standard.

How to extend the warranty

If your Warmflow boiler installed by an installer who is a Warmflow Connect scheme member, it will be covered by a 5 year warranty. Alternatively, the warranty can be extended to 5 years for a small fee.

What's covered by the warranty?

The warranty period includes all controls, plate heat exchangers and associated equipment contained within the boiler casing, such as the burner and flue system (if supplied by Warmflow).

Terms and conditions

The boiler must be installed and commissioned by a Warmflow Connect engineer, or an alternative engineer who is OFTEC registered. After the boiler has been installed, you'll need to either complete and return the guarantee registration form to Warmflow or register online, within 30 days.

To keep the warranty valid, your Warmflow boiler needs to be serviced by a Warmflow or OFTEC registered engineer every 12 months after the date of installation for the length of the warranty period.

How to register your warranty

You can either fill and return the guarantee registration form and send it back to Warmflow, or register online via the Warmflow website.
