By using TASSU underfloor heating cables, a direct or partial storage floor heating can be carried out. The direct underfloor heating is used in wet or damp areas, where the floormaterial is low thermal resistant, e.g. clinker. The direct underfloor heating is suitable also in other areas as the only heating form. The partial storage underfloor heating is used for example in living rooms and kitchens. The output per square meter should be 80-150 W/m², the installation distance 13 – 25 cm and the installation depth 5-10 cm. The heating cable is a preterminated twin-conductor cable with a PVC sheath. The lowest installation temperature is -10°C. The output of the cable is 20W/m with a nominal voltage of 230V. The heating cable is supplied with a cold lead of 2.5 or 3,0 meter.
