Self regulating heating cables offer protection against burst water pipes, frozen roof gutters, ice or snow-covered ramps, stairways and walkways. The use of these systems provides a reliable and long-term solution to costly damage or operational disturbances. But how do they work?

When Do You Need Self Regulating Heating Cables?

Despite being a productive counter to ice damage, thermal insulation alone can’t offer total protection against frost damage to piping. And, pipes aren’t the only things that need to be protected during Winter, as frost can also affect drains and sewers. There are alternative systems, but many of them don’t offer energy-efficient options and require ongoing maintenance. 

However, a self-regulating system protects buildings against the damage of frost while offering many other benefits. 

How Do Self Regulating Heating Cables Work?

Self regulating systems work by:

  • Attaching the heating cable in a straight line underneath the insulation on the pipe.
  • Applying heating power in relation to the ambient temperature to maintain a holding temperature above freezing.
  • As the ambient temperature changes, the differential with the holding temperature, heat flow and energy consumption are reduced accordingly.

This makes self regulating systems the energy-efficient option, as they power on only when the temperature drops.

Why Should You Consider Self Regulating Systems?

During winter, ice can cause many dangerous situations in buildings. 

  • There have been many instances of icicles falling from gutters causing serious injuries to people below.
  • If temperatures rise during the day, the melted water cannot run off through drains and will spill over courtyards and walkways. When it refreezes at night, it can produce a dangerously icy surface.
  • Ice can cause damage to gutters and drains. A malfunctioning roof draining system poses risks to the building itself, especially to the roof and facade.

Self-regulating heating cables are highly effective in protecting pipework against frost damage while remaining a safe option. The technology is designed for a variety of applications including inside homes and buildings.

Add all of this together, and it’s easy to see that frost damage to buildings and service lines can be avoided while reducing operating costs thanks to the functionality and versatility of freeze protection systems.
