Heating cable for underfloor heating SH10 – 230 V, 10 W/m

The SH10 heating cable is designed for electric underfloor heating in interiors. It is a reliable and proven solution for comfortable temperature control and the main source of heating of floor surfaces. Thanks to the constant power of 10 W per meter, it ensures even heat distribution and long-term stable operation at 230 V AC power supply.

How to choose the right length of heating cable

Choosing the right length of heating cable depends on the total power required and the size of the heated area. The SH10 cable has a fixed power of 10 W per meter of length, therefore the total power is calculated simply by multiplying the cable length.

• 10 m cable = 100 W
• 15 m cable = 150 W
• 20 m cable = 200 W
• 25 m cable = 250 W
• 50 m cable = 500 W

For underfloor heating, a surface power of 50–75 W/m² is commonly used, depending on the type of room, the composition of the floor and the level of thermal insulation. The cable length must be selected so that the total power corresponds to this value. The cable is never shortened – the correct length is always selected according to the design.

Expert explanation of the function

The SH10 heating cable works on the principle of resistance heating. After connecting to a 230 V AC network, an electric current flows through the conductor, which is converted into heat due to electrical resistance. This heat is evenly transferred to the floor structure, where it is accumulated and gradually radiated into the space.

The cable is intended for installation in screed, self-leveling compound or under tiles. For proper function and safe operation, it must always be used in conjunction with a floor thermostat and temperature sensor, which provide regulation and protection against overheating.
