Heating cables play a crucial role in the operation and maintenance of underfloor heating systems, especially in relation to frost protection. These unique units generate heat along their length and can effectively prevent the water pipes in underfloor heating systems from freezing under extreme temperature conditions. Heating cables are a reliable solution that ensures the system's lifespan, efficiency, and reliability through the cold months. Below, we will delve into the basic principles of heating cables, their use in underfloor heating systems, and the importance of frost-proofing your cables.

How does a heating cable work?

A heating cable is an essential component in an underfloor heating system. It operates by conducting electric current through a resistive element, most often a metal wire or strip, which results in the production of heat. This heating cable is typically embedded in the floor and generates the necessary heat to warm the surface, thus creating a comfortable atmosphere in the room.

The heating cable is installed beneath the floor covering in loops at a certain distance apart, depending on the desired heat output and the insulation capacity of the floor. Electricity passes through the cable, generates heat, which is then transferred to the floor, heating it, and thus the room the floor is located in.

Heating cables for underfloor heating can be of different types, but self-regulating cables are particularly popular. They automatically adjust their heat output based on the ambient temperature, providing optimal efficiency and energy savings. In this way, the heating cable ensures constant and even heating, regardless of the outdoor temperature.

How does a self-regulating heating cable work?

Self-regulating heating cables for underfloor heating are advanced systems that adjust their heat production according to the ambient temperature. The inner core of the cable contains two conductors surrounded by a semi-conductive polymer material that changes its electrical resistance based on the temperature. At low temperatures, the resistance decreases, which leads to increased current flow and therefore more heat.

At higher temperatures, the resistance increases, reducing the current and thus the heat. This allows the system to adapt its heat production, minimizing energy consumption and ensuring an even temperature, regardless of the room's size, shape, or construction. In other words, a self-regulating heating cable is an advanced yet energy-efficient solution for those wishing to install underfloor heating in their homes.

Multi-purpose heating cables

Heating cables for underfloor heating can be installed in different areas of the home to ensure comfort and warmth. The bathroom is a popular place as it provides pleasantly warm floors on cold mornings. The kitchen is also a suitable place as it often serves as a central room in the home with much traffic. Living rooms and bedrooms can also benefit from underfloor heating for added comfort. If you live in a country like Denmark, with changing temperatures and many months of frost, it is also essential to pay attention to frost protection for your heating cable..

Heating cables can also be useful in basement areas, which are often colder. In entrance areas or utility rooms, where you often take off your coat and shoes, underfloor heating can be a welcome luxury. However, the installation should always be considered in relation to the type of floor, as some materials conduct heat better than others.

Can you install heating cables yourself?

In Denmark, there are specific rules for installing heating cables yourself. According to the Safety Authority's rules, only simple electrical work is allowed to be performed by private individuals. However, the installation of heating cables in the floor is not considered simple electrical work and therefore requires an authorized electrician. This is because the work involves risks of both electric shock and fire hazards. Moreover, it is important to note that any errors in the installation can affect the building's insurance coverage.

If the heating cables are part of a heat pump installation, this must be reported to the energy company, as it is considered a fixed electrical installation. It is, therefore, strictly regulated and requires professional expertise. However, it is allowed to lay the heating cables yourself, but when it comes to the electrical work, the Danish rules in the area require that you hire an authorized electrician to carry out the rest of the task. By hiring a professional, you can be sure that the work is carried out correctly and safely.


How much is a heating cable?

The cost of different heating cables varies. This is due to several factors, such as type and quality. At Handyheat, prices start at DKK 250 and up, which means that you can get quality cables at an affordable price.

Which heating cable should one choose?

The choice of heating cable does not directly depend on its location in the home, but rather on the type of floor covering and insulation. Self-regulating heating cables are generally suitable for most rooms and floor types, including wood, tiles, and concrete. It is a good idea to seek professional advice before making your final choice.
