Installation of charging floor heating

The heating cable is cast inside the concrete slab, in a depth of app. 50 mm. The slab should be app. 100 mm thick. The slab can be cast in one or two (recommended) phases.

Handle the cables carefully during the installation. Do not use a vibrating concrete mixer. Fix the cables with plastic strip - not with wire. Do not walk on the cables.

 
Casting in two phases

The lower part of the slab (app. 50 mm) is cast first. The heating cable is fixed on the slab, and the upper part is cast. This method prevents the cable from damaging during the installation.
 
  1. Ground  

  2 Tightened gravel
  3. Heat insulation
  4. Plastic foil
  5. Reinforced concrete slab - clean the surface well before cable is laid
  6. Installation clips, fixed in the cast
  7. Heating cable
  8. Leveling concrete - don't use a vibrator! Installation depth 50 mm (in continuous heating 30 mm). The slab should not be thicker than 100 mm.
  9. Floor covering
  10. Thermostat
  11. Thermostat sensor in a closed tube, halfway between two cable runs
 
 
Casting in one phase

The heating cable is fixed onto the reinforcement mesh. Concrete is cast in one phase and the cable remains inside it.
 
  1. Ground

  2. Tightened gravel
  3. Heat insulation
  4. Plastic foil
  5. Reinforcing mesh
  6. Reinforcing mesh
  7. Heating cable (fix onto mesh)
  8. Leveling concrete (don't use vibrator) - in charging heating, the thickness of the slab should not be thicker than 100 cm. Installation depth 30 mm (continuous) or 50 mm (charging)
