20-year full warranty

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 authorized 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.
