12 year warranty. We guarantee the products for 12 years and, in case of any defect, repair the damaged heating cable or offer you a new product. This warranty does not include preparatory work, i.e., works involved in locating the product and restoring the floor. Negligible magnetic fields. In the vicinity of electrical appliances, such as household appliances and home electronics, electric and magnetic fields may form. There is speculation that these fields may cause health problems. Since the heating cable is continuously switched on wherever people are present, it is important to choose a heating cable that does not emit unnecessary electric or magnetic fields. T2 products are made in such a way that they emit the lowest possible electric and magnetic fields, well below the supposed marginal values presently being discussed. In other words, T2 means the peace of mind option PVC-free. Our products are completely free from PVC. T2 products help to improve the environment.
