Self-limiting Cables

Self-limiting heating cables

The self-limiting heating cables for indoors are used for maintenance of the hot water supply and other fluids that need to maintain a certain temperature. The self-limiting capability of the cable ensures that the output increases or decreases according to the surrounding temperature. It ensures hot water in all taps, providing savings compared to a circulatory hot water system.

Heating cable reduces water waste as hot water is immediately supplied.

Protection against Legionella—the system maintains the water supply at the required temperature level and provides appropriate disinfection to suppress the Legionella bacteria.

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.

DEVIhotwatt™ (B) / EChotwatt 45/55/70

The DEVIhotwatt™ (B) / EChotwatt 45/55/70 is a self-limiting heating cable that is used for temperature maintenance of the hot water supply and other fluids that need to maintain a certain temperature. The self-limiting capability of the cable ensures that the output increases or decreases according to ambient temperature. It ensures hot water in all taps and savings when circulation of the whole pipe system is unnecessary.

Features and benefits using self-limiting cables

Provide appropriate disinfection to suppress the Legionella bacteria

Reduce water waste as you can get hot water immediately

50% less pipes, insulation, valves, and pumps to be installed since no return pipes are required

Heating cables provide power where needed adapting output according to the ambient temperature
