Heating cable HiSmart HT260164 300W 25 m — electric trace heating cable for frost protection and pipe heating

Electric Heating Cable 300W, 25m, 12W/m, AC 230V is a slim constant-power underfloor heating cable designed to deliver even and reliable heat in indoor spaces. With a 3.6 mm diameter and a solid heating core, the cable provides precise 12 W/m output along its full length and is intended for installation under tiles, stone, laminate, wood floors and similar coverings. The twin-conductor design allows single-end connection for easier installation in renovation projects and areas with limited installation height. Inner FEP insulation, an outer PVC jacket and an integrated aluminum shielding layer provide thermal resistance, mechanical protection and reduced electromagnetic interference. The product is suitable for wet areas (IP68) and is controlled via a thermostat to avoid overheating. Technical data: 25 m length, 300 W total power, AC 230 V, resistance 176.33 Ω, cold lead 2.5 m, resistance tolerance +10% / -5%, certifications CE, EAC, TUV, CSA — warranty 25 years.

Advantages

The heating cable combines a very small diameter (3.6 mm) with a solid heating core for uniform temperature distribution and stable power output of 12 W/m. Twin-conductor single-end connection simplifies routing and speeds up installation in bathrooms, corridors and other confined or irregular spaces. FEP insulation, PVC outer jacket and aluminum-plastic shielding ensure durability, mechanical protection, high thermal resistance and minimized electromagnetic interference. The cable is rated IP68 for waterproof installation and is compatible with thermostats to optimize energy use and protect floors from overheating.

Suitable for

• Under-tile or under-laminate underfloor heating in bathrooms and kitchens
• Renovation projects with limited installation depth
• Residential and light commercial spaces (corridors, rooms, small offices)
• Wet zones and areas requiring IP68-rated waterproofing

How to use

Select the required cable length based on the heated floor area and the chosen cable spacing — for typical rooms a spacing of approximately 12 cm is recommended. 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 into tile adhesive or leveling compound according to the floor covering manufacturer’s instructions and the thermostat installation requirements. Connect the twin-conductor cable from one end to the thermostat and feed the cold lead to the thermostat location; ensure correct electrical protection and grounding. Use a qualified electrician for final electrical connections and follow local regulations and the thermostat manufacturer’s instructions.

Usage recommendations

For durable and safe performance, install the heating cable with appropriate floor insulation, maintain the recommended spacing (about 12 cm for standard layouts), and control the system with a compatible thermostat and floor sensor. Do not cut the heating cable; use only the cold lead for connections. For wet areas and outdoor-adjacent installations, verify sealing and waterproofing per local codes and follow manufacturer guidance.
