Image: DEVISelf-limiting heating cable fixed along water pipes and under the insulation stops them freezing and bursting in exposed or unheated locations. The cable puts out more heat where the pipe is colder.
Benefits and advantages
- Prevents frozen and burst pipes, and the water damage that follows
- Self-limiting: output adjusts along its length as temperatures change
- Cut to length on site, or ready-made lengths with a plug
- Small cable size for easy fitting
- Low running cost: runs only near freezing when thermostatically controlled
System design starting points
- DEVIpipeheat 10 V2 (10 W/m at 10 °C) on the outside of the pipe, under weatherproof insulation
- Maximum 100 m of cable on a 10 A C-curve breaker at 10 °C
- Must be controlled by a thermostat and protected by a 30 mA RCD
- Control with a DEVIreg 330 (-10 to +10 °C range) and sensor
Typical uses
Exposed and roof-space pipesTank outlets and metersFire and sprinkler lines
