Heating cable HiSmart HT260171 375W 31.25m — electric trace heating cable for frost protection and pipe heating

Electric Heating Cable HiSmart HT260171, 375 W (31.25 m), 12 W/m, AC 230 V — thin constant-power underfloor and trace heating cable designed to provide even and reliable heat distribution in indoor spaces and for frost protection on pipes and gutters. With a slim 3.6 mm diameter and a solid heating core, the cable delivers precise 12 W per meter, resists overheating and can be embedded in tile adhesive, leveling compounds or laid along pipes for frost protection. The twin-conductor design enables single-end connection for simpler installation in confined or complex layouts. FEP inner insulation and a PVC outer jacket with integrated aluminum shielding ensure thermal resistance, mechanical protection and reduced electromagnetic interference. The cable is rated IP68 and supplied with a 2.5 m cold lead; control is provided via a thermostat to optimize energy use and protect the floor or pipe from overheating.

Advantages

The HiSmart HT260171 heating cable offers a compact 3.6 mm profile suitable for renovations and low-build installations, constant power output of 12 W/m for predictable heating, and a solid heating core that ensures uniform temperature along the full length. Twin-conductor single-end connection simplifies installation in bathrooms, corridors or along pipes. Durable FEP insulation and PVC outer jacket with aluminum shielding provide high thermal stability, mechanical protection and reduced electromagnetic interference. The cable is IP68 rated and certified (CE, EAC, TUV, CSA), and comes with a 25-year warranty.

How to use

Determine the required cable length based on the heated area and chosen spacing. For typical indoor installations a spacing of about 12 cm is recommended; calculate approximate cable length by dividing heated floor area (m²) by spacing in meters (e.g., 6 m² ÷ 0.12 m = 50 m). Lay the cable in tile adhesive, leveling compound or attach it along pipes or gutters according to the layout, keeping the specified spacing and avoiding overlaps. Connect the cable to the supply and thermostat using the single-end connection and the provided cold lead; ensure short-circuit protection and follow local electrical codes. Use appropriate sensors and a thermostat to control temperature and prevent overheating.

Usage recommendations

Install only in accordance with local regulations and manufacturer instructions; verify floor covering compatibility and required insulation layers. Do not overlap the heating cable, and ensure thermostat and temperature sensor placement follows the installation manual. For pipe tracing, secure the cable to the pipe and provide proper waterproofing and fixation where required.
