Floor heating: electric in-slab cable

Electric in-slab heating with Safe-t-SLAB cable

Safe-t-SLAB is an electrical resistance heating cable, fixed to the reinforcing mesh before the concrete is poured. The slab then stores warmth and releases it slowly into the room.

How it works

How the slab stores and releases warmth

The cable warms the concrete. Because the slab holds heat, the stored warmth is released over the following hours. Where an off-peak tariff is available, the system can be scheduled to run during those hours.

Suitability

Is in-slab heating right for your project?

Well suited to

  • New homes and extensions on a concrete slab
  • Projects planned with the builder and concreter
  • Larger floor areas
  • Cold-store floors, where slab heating is specified to help prevent frost heave

Things to consider

  • It must be installed before the pour, so it cannot be added to an existing slab
  • The slab takes time to warm up and cool down
  • Running costs depend on your tariff and how the system is controlled
  • A licensed electrician connects the system

What Ron will ask about

  • Your suburb or postcode
  • Slab plans and the areas to heat
  • The construction timetable and pour date
  • Your electricity tariff, if known
  • For cold stores, the room temperature range

How a project runs

From assessment to installation

  1. Assessment

    Send Ron the slab plans and your construction timetable.

  2. Specified quote

    Cable selection, layout and controls, ready before the pour.

  3. Supply

    CBS supplies the specified cable and controls in time for the slab work.

  4. Installation guidance

    The cable is fixed to the mesh before the pour, and a licensed electrician connects the system, with Ron's technical guidance. Installation arrangements are discussed case by case.

Existing slab? See under-tile cable, ultra-thin cable or carbon film on top of the slab, or ceiling heating.
