WM cable maintaining water at a desired temperature
WM hot water maintenance cable is self-regulating. This means that the cables output reduces as the pipe temperature increases and that the cable cannot overheat or burn out.
The cable should be fixed to a water pipe in a straight line and must be covered with insulation. WM can be used with plastic or stainless-steel pipes but these pipes must be wrapped in aluminium tape before the cable is installed.
Insulation Thickness (mm) – Cable should be installed in a straight line under installation
Maximum circuit length and breaker size
|Max. Circuit (m)
Selection of Ancillary items
One CRJ-T1 termination kit will be required per circuit. The kit includes the necessary crimps and shrink-on material to prepare one end of the cable for electrical connection and to effectively seal the far end. The kit also includes a nylon gland suitable for making a moisture tight seal into a suitable terminal enclosure.
One CRJ-S1 slice kit will be required for each splice or T joint. . The kit includes the necessary crimps and shrink-on material to join two lengths of cable and to effectively seal the far end.
PF-T fixing tape is supplied in 33m rolls and is ideal for fixing heating cable to the pipe. We recommend securing the cable at 200mm intervals.
When heating a plastic pipe, the pipe should be wrapped in aluminium tape before the heating cable is installed. AL-50 is supplied in 45m x 50mm rolls.
PF-L warning labels are supplied as a pack of 10 and should be fixed to the outside of the insulation at regular intervals.
