Based on 80 years of experience, DEVI Electric Heating products deliver value for customers through quality, reliability and innovation and are backed by market-leading support.

This support includes DEVIwarranty™ which covers not only cable or mat replacement but also the cost of installation and materials – for up to 20 years! The warranty is a series of five individual, best-in-market warranties to give you full peace of mind while using Electric Heating products.

DEVI Electric Heating provides solutions for electric heating with a dedicated focus on advanced and user friendly systems, delivering all products dedicated to this for both indoor and outdoor.

These solutions are covered by a wide range of products e.g. heating cables, heating mats, self-limiting cables, contemporary thermostats and accessories.

A 20-year full service warranty is valid for DEVI electrical heating cables and mats.

You can rely on the DEVI quality; but, in the event of failure, the DEVI cables or mats, which can be tracked back to a manufacturing defect in the DEVI product, can be repaired or replaced free of charge.

Not only does this warranty include costs of reparation or replacement, but also installation and floor materials, such as damage to brickwork and tiles.

The installation of DEVI products must be performed by an authorised installer in order to apply for this warranty, and the warranty certificate has to be stamped, signed, and provided. For more details, read our warranty terms and conditions.
