  • Approved for use with the following finished flooring: Ceramic tile, porcelain tile, granite, marble, natural stone and luxury vinyl tile (LVT).

Mapeheat Cable Recommendations

  • Never cut, shorten or modify the heating cable in any way; it will change the electrical characteristics of the cables and possibly cause overheating and a fire.
  • Never allow the cable to overlap or cross over itself.
  • Do not use in exterior applications.
  • Do not use with solid, hardwood flooring.
  • If LVT is being installed, ensure that the manufacturer’s instructions allow for use with radiant heating systems and that the LVT is acclimated at least 24 hours before installation.
  • Do not place objects directly on top of the floor that could impede/trap heat emanating from the floor heating system including but not limited to flush-to-floor furniture, rubber or memory-foam mats, and mattresses. These objects could cause unsafe temperatures to be reached underneath these objects that may damage the object and/or the flooring material.
  • Do not install Mapeheat Cable in direct contact with any combustible surfaces, or install it in/on/under walls or in closets.
  • Do not lay heating cable under cabinets, fixtures or appliances.
  • Do not extend Mapeheat Cable beyond the room or area in which it originates.
  • Do not use over cracks or control joints subject to out-of-plane movement, or where in-plane movement exists greater than 3 mm.
  • Do not use over Woodplank flooring, metal, fibreglass, laminate or any other dimensionally unstable substrate.
  • Do not use in areas at will be constantly submerged or subject to standing water.
  • Do not use on bituminous substrates.
  • Do not use on highly flammable material.
  • The total R-value of layers on top of heating products should not exceed R value of 0,15m2K/W.
  • Floor temperature is limited by the thermostat to + 40°C. The typical operating temperature range of Mapeheat systems is +27°C to +35°C.

Suitable Substrates

When used over sand/cement screed, the screed must be suitable to support tile installation traffic without leaving indentation as determined by the project design professional, construction manager or general contractor.

  • Cement mortar beds and levelling coats.
  • Tile backer boards.
  • Exterior grade plywood refer to BS 5385 part 3.
  • Existing, well-bonded ceramic tile and dimensionally stable natural stone.
  • Existing, cement terrazzo floors.

Consult MAPEl’s Technical Services Department for installation recommendations regarding substrates and conditions not listed.

Surface Preparation

  • All substrates should be dry, flat, structurally sound and free from loose materials, grease, oil, and any contaminant that can reduce the aualitv of the bond.
  • Anhydrite or screeds containing calcium sulphates should be dry to 0.5%W/w when measured with a carbide hygrometer. All surface laitance should be removed and the screed should be primed with a suitable MAPEI primer.
  • To improve the upward heat transfer from the cable to the flooring surface, best practice is to insulate the concrete slab subfloor before installing Mapeheat Cable.
  • Before installing consult a qualified electrician.
  • Any modification of or tampering with Mapeheat Cable will completely void the manufacturer warranty and liability.
  • Do not connect the Mapeheat Cable while it is on the spool; this could damage the cable and cause a fire.

  • The installation of Mapeheat Cable must be in accordance with these instructions and in accordance with the relevant UKand or EU standards. Please see the Mapeheat Cable Installation Manual for more information.
  • The thermostat used in the floor-heating system must be compliant with the relevant UKand EU standards.

  • Mapeheat Membrane, is the only approved accessories to secure Mapeheat Cable onto the subfloor.
  • Indicate on the electrical panel which circuit is used for the Mapeheat Cable System
  • The entire heating portion of Mapeheat Cable and mechanical joint must be secured to the floor and covered with self-levelling underlayment or tile adhesive.
  • Keep the ends of heating devices and kit components dry before and during installation.
  • To improve the upward heat transfer from the cable to the flooring surface, insulate the concrete slab subfloor before installing Mapeheat Cable.

BTP very helpful in supplying a pallet of floor leveller. I needed it on the Saturday, but didn’t want it sitting on the driveway for several days. I called and they recommended ordering for Thursday to give a day’s grace in case of any delivery issues. In the event the pallet arrived on Thursday as requested. Reliable and good value
