Underfloor Heating Wire Construction – 100% Aluminium Earth Shield

In electric underfloor heating wires a 100% aluminium earth shield is the most assured way of guaranteeing a heating cable is fully earth protected. The aluminium layer is wrapped around the heating element wires and it also incorporates an earth drain wire to ensure the system will trip the RCD if there is any earth leakage.

Heating cables with aluminium earth shields comply with the most stringent electrical regulations and they never require an earthing grid to be installed above them when used in wet rooms such as bathrooms.
