Home heating cable for frost protection that helps prevent burst pipes and icy gutters. Homeowners gain peace of mind from consistent, weatherproof operation with errorpot Heat Cable. Will it suit every installation and power supply?

⚡ At a Glance
  • Heating Performance: Nominal 20 W/m output for steady frost prevention along runs
  • Best for: Homeowners protecting pipes, gutters and small outdoor plumbing from freezing
  • Not ideal for: Large industrial heating projects that require thermostatic control or high power density

Self-regulating heating cable available for 24V DC and 220V AC use. PE-sheathed construction and composite insulation make it suitable for outdoor frost-protection tasks.


Overheat protection – thanks to self-regulating output

The cable adjusts its output according to ambient temperature, eliminating the need for a separate temperature controller. Manufacturer notes state the cable will not overheat under normal use.

Reduced fire and damage risk during freeze conditions, so installations remain safe without an added thermostat. Safer operation is particularly useful for unattended exterior runs.

Flexible installation – with cut-to-length within circuit limits

Cable can be trimmed to suit the required run as long as the maximum circuit length is respected (24V: 15 m, 220V: 30 m). Any metres beyond the stated maximum will not produce heat.

Customisable lengths simplify routing along irregular pipework and gutters without waste. Planning runs to stay within the maximum ensures every metre heats as intended.

Weatherproof durability – with PE sheath and composite insulation

Outer PE sheath combined with an internal PE composite insulating layer provides enhanced sealing and protection. Product description specifies waterproofing and fire-retardant properties.

Suitable for exposed locations such as roofs, gutters and outdoor pipes where moisture and cold are present. Long service life can be expected when correctly installed and secured.

✨ The 4 Key Reasons for errorpot Heat Cable
  1. 24V and 220V compatibility – Compatible with 24V DC and 220V AC supply types
  2. Maximum circuit length – Extra metres beyond limit remain unheated, avoiding overloads
  3. Slim profile – 8mm by 3mm cable fits inside narrow pipe clips easily
  4. Durable PE sheath – Waterproof and fire-retardant for long outdoor service life

❓ Frequently Asked Questions

Q: Does the cable need a thermostat?

A: No, the cable is self-regulating and adjusts output with temperature, so a separate thermostat is not required.

Q: Can the cable be cut to fit my run?

A: Yes, the cable may be cut to length provided the maximum circuit length is not exceeded (24V: 15 m, 220V: 30 m); any excess beyond the maximum will not heat.

Q: Is the cable suitable for outdoor use on gutters and roofs?

A: Yes, the outer PE sheath and internal PE composite insulation are described as waterproof and fire retardant, making the cable suitable for outdoor frost-protection applications.
