The self-limiting capability of the cable ensures that the output of the cable increase or decrease according to the surrounding temperature.

Lower initial investment of DHW (Domestic Hot Water) system without circulation – appx. 50% less pipes, insulation, valves, and pumps to be installed as no return pipes and insulation are required.​

Space saving – no need for return pipe gives more room in service ducts.
