Heating cable HiSmart HT260232 — 900W total, 75 m length

Heating cable HiSmart HT260232 — 900W, 75 m, 12 W/m is a thin, constant‑power underfloor heating cable designed to provide even heat distribution in indoor spaces. With an outer diameter of 3.6 mm and a solid heating core, the cable delivers a precise power output of 12 W per metre and is suitable for installation under tiles, stone, laminate, wood floors and similar coverings. The twin conductor design enables single‑end connection for simplified installation. The cable includes FEP inner insulation, PVC outer jacket and an integrated aluminium shielding layer; it is rated IP68 and supplied with a 2.5 m cold lead. Total power output for the 75 m variant is 900 W.

Advantages

The cable’s slim 3.6 mm profile and flexible construction make it suitable for renovation projects and areas with limited installation height. The solid heating core ensures uniform temperature along the entire length and reduces the risk of hotspots. Twin conductor single‑end connection speeds up installation in confined or irregular spaces. FEP insulation and PVC jacket provide thermal resistance and mechanical protection, while the aluminium shield minimises electromagnetic interference. IP68 protection and quality certifications (CE, EAC, TUV, CSA) support safe use in residential wet zones when installed according to requirements.

Suitable for

• Underfloor heating in bathrooms, kitchens and corridors
• Installation beneath tiles, natural stone, laminate and wood flooring
• New construction and renovation projects with limited floor build‑up
• Wet areas requiring IP68 rated heating solutions

How to use

Determine the required cable length based on the heated floor area and chosen spacing. A typical spacing for standard rooms is approximately 12 cm; calculate cable length by dividing the heated area (m²) by the spacing in metres (for example, 6 m² ÷ 0.12 m ≈ 50 m). Lay the cable in tile adhesive or levelling compound according to the manufacturer’s installation instructions and local regulations, leaving the specified cold lead and making the single‑end electrical connection. Control the heating circuit using a compatible floor thermostat to regulate temperature and prevent overheating. Ensure all electrical connections and installations are carried out by a qualified electrician.

Usage recommendations

Do not install the cable directly under carpets or insulated floor coverings that restrict heat dissipation. Verify compatibility of the floor covering and adhesion materials with electric underfloor heating. For wet areas, follow IP68 installation requirements and use appropriate sealing and grounding. Refer to product documentation and local standards for spacing, maximum surface temperatures and thermostat settings.
