soojuskaablid

Soojuskaablid are electrical heating cables designed to generate heat when powered, used to prevent freezing, melt snow and ice, or provide radiant floor heating. They consist of a resistive heating core surrounded by insulation and a protective jacket. Some cables include a self-regulating polymer core that changes heat output with surface temperature, while others are constant-wattage types that produce a fixed heat output along their length. They are typically controlled by a thermostat, a temperature sensor, and sometimes a dedicated heat-trace controller.

Common applications include underfloor heating in residential and commercial spaces, roof and gutter de-icing to prevent ice dams, and freeze protection for water pipes, tanks, or other equipment exposed to cold temperatures. The choice of cable type depends on the application, desired heat output, installation method, and local electrical codes.

Installation and design considerations are important for safe and efficient operation. The system must be sized to the area or pipe length, powered by an appropriate voltage, and integrated with a suitable thermostat and protection devices. Self-regulating cables simplify installation and offer a higher margin of safety in variable-temperature environments, while constant-wattage cables can provide precise heat output for large areas when properly spaced. Proper insulation, moisture protection, and restrictions on electrical connections in wet or outdoor locations are essential. Installations typically require licensed electrical work and must comply with national electrical codes and relevant standards; in many regions, products are CE-marked and meet local building and safety requirements.

Maintenance involves regular inspections for damage, improper insulation, or moisture ingress, and prompt replacement if faults are found.
