Loose Cable Flooring Information

  • You can use the Warmup® Underfloor Heating System under carpet, vinyl, wood or any ceramic or natural stone floor tile such as slate, porcelain, limestone, marble and terracotta. You can even use the heater under thicker floor finishes such as flagstones - just plan a little more time for the floor to heat up.
  • You may choose to cover or protect the heater as part of pre-floor finishing work with a cement-based smoothing underlayment (this is especially useful when laying flagstones). Follow the floor manufacturer's instructions closely, using grout and thin-set tile adhesive, each with a compatible latex additive.
  • You may install the heater on an interior wood subfloor or solid (concrete slab) sub-floor. In either case, a cement backer board should be installed for maximum stability. If you are using a water proofing, or moisture barrier system, consult with the system manufacturer to establish if the membrane must be fitted above or below the heater. Please bear in mind that the heating element can reach temperatures of 131°F, so it may be necessary to use a skim or scratch coat layer to dissipate the heat.
Preparing interior wood subfloors
  • When installing the heater to a timber sub-floor, make sure you fix a suitable tile-backer board to the existing floor. Prior to installation, attach the existing floorboards securely and, if necessary, ensure a flush fit by first levelling with a latex or cement underlayment.
  • Secure the backer board according to the manufacturer's recommendations and in line with the American National Standards Institute (ANSI) specifications. Tile and stone installation should also conform to TCA (Tile Council of America) guidelines. Underlayment fasteners should not penetrate joists below.
  • Chipboard, MDO and other particle boards are not appropriate bases for tiling.
Preparing solid floors
  • When installing flooring onto a concrete slab sub-floor, Warmup recommends using insulated polystyrene tile-backer insulation board to improve the performance and efficiency of the heating system so that no heat is lost into the subfloor.
  • Warmup Loose Cable Systems will work with un-insulated concrete sub-floors, but once completed, the floor will take significantly longer to heat up because some heat will be lost to the subfloor, leading to extended heat-up times and higher running costs.
