Installation of heating cable
The installation of the heating cable must be adjusted to the method of construction of the stair. To obtain quick and even melting of the stairs it is important that the cable is applied in an adequate depth (30-50mm below the surface).
Single-course casting
The cable is lashed on to the armouring with a plastic coated lashing wire or electrical tape. If the armouring is placed too deep down special fixing irons are to be mounted for the heating cable. This application work has to be supervised by a competent engineer. The cable should always be tested (mega tested and ohm-measured) by a responsible electrician before the floor concrete is applied. You have to be very careful not to damage the cable when applying the floor concrete.
Double-course casting
Special fixing strips for the heating cables are mounted on the group-stone mortar. The heating cable is applied and is fixed to the strips with the plate tabs. This work has to be supervised by a competent engineer. The cable should always be tested (megatested and ohm-measured) by a responsible electrician before the floor concrete is applied. You have to be very careful not to damage the cable when applying the concrete.
Tiling
Application according to the double-course casting. Please pay attention to the fact that the thickness of tiles can make the cables go too far down below the surface.
Please note! Do not forget to apply a plastic tube/pipe for possible thermostat sensors. The pipe should be plugged at the termination end not to let concrete or finishing mortar penetrate. Flexible tubing are often used for electrical wires.
