Gutter heating

As a result of cold temperatures, snowfall and alternating freezing and melting stages, winter poses a great risk to roofs and gutters. Ice can form due to heat losses from buildings and unfavourable solar radiation. The melt water that forms here cannot drain off and freezes. This may lead to burst downpipes, water ingress in buildings and damage to outer facades.

Your benefits from a Perobe gutter heating system:

  • Output of 25 – 27 watts
  • Watertight
  • UV-resistant outer sheath
  • Ready to connect directly to an existing 230 V socket
  • Incl. control thermostat and plastic spacers (for installation)

How long does the heating installation have to be?

The following formula can be used to calculate what you need overall:

2 x length of gutter + 2 x length of downpipe + 1 m at the end (frost area)

Easy to assemble

First place the thermostat (at the end of the heating line) at the coldest point of the gutter (the part not exposed to direct sunlight). The thermostat switches the heating cable on at approx. + 5°C. The heating cable is laid in the gutter with the aid of the spacers, which prevent the heating lines from touching one another. Make sure that the melt water of the gutter heating system can drain into a frost-free area.


Pre-assembled heating lines with a seamless gland transition and chemical-resistant PTFE insulation are used in the gutter heating systems. The gland transition is completely watertight and ideally suited to this application (moisture protection).

In line with VDE 0100, the electrical connection must be carried out by a certified electrician using a residual current device with a cut-off current of 30 mA. The plug for connecting the system to the power supply must remain easily accessible at all times.

The residual current device (< 30 mA) is mandatory as a protective measure.
