The warranty is a series of five individual, best-in-market warranties to give you full peace of mind while using Electric Heating products

We provide two warranty types:

Product warranty

The product warranty is valid for the agreed warranty period and shall offer a new comparable product or repair of the product if it is found to be faulty by reason of defective design, materials or workmanship. This warranty covers all our products that are not covered by Full-service warranty. Its term may vary depending on different product types (as shown in the table below).

Product warranty covers costs for:

  • Product replacement with a new comparable product or 
repair of the product
  • Transportation costs

Full-service warranty

If the product is covered by full-service warranty, in addition to repair or replacement of the defective product Danfoss will also compensate installation costs and any damage to floor/surface materials (e.g. brickwork, tiles and roof surface) if the damage is caused by the defective product or is an unavoidable result of repairing the defective product.

Except for such costs and damage, Danfoss shall not be liable for any resulting losses or consequential or incidental damages including, but not limited to, damages to property or extra utility expenses. No extension of the warranty period following repairs undertaken is granted.



Full-service warranty is valid for resistive ready-made heating cables and mats.

Full-service warranty covers costs for:

  • Inspection of the warranty claim
  • Product replacement with a new comparable product or repair the product
  • Payments for the installation
  • Floor materials of similar type or price level (e.g. damage to brickwork and tiles)
  • Transportation costs

The warranty shall be valid only if the WARRANTY CERTIFICATE is completed correctly and in accordance with the instructions; and provided if the fault is submitted to the installer or the seller without undue delay and proof of purchase is provided. The warranty shall not cover any damage caused by incorrect conditions of use, incorrect installation or if installation has been carried out by non-authorized installers. All work will be invoiced in full if Danfoss is required to inspect or repair faults that have arisen as a result of any of the above. The DEVIwarranty shall not extend to products which have not been paid in full. Danfoss will, at all times, provide a rapid and effective response to all complaints and inquiries from our customers. All claims not meeting the above conditions are explicitly excluded from the DEVIwarranty.
