Loose Wire Underfloor Heating Installation

STEP 1
Smooth, clean and dry the subfloor surface. Paint the floor with Warmup Primer (you do not need to use primer if installing on an insulated tile back board). The light green colour of the primer will change to a dark green once dry. Avoid traffic once primer is down.
STEP 2
Calculate in square metres the size of the area to be heated. Use the Sizing Guide (found in the back of the Installation Manual) to correctly fit your heating wire into the space provided. Layout the heating wire in parallel lines. Begin at the start point and in U shapes go to the furthest point. Using the wire spacing markings as tape down points, secure the heating wire to the floor with adhesive tape. Once completed, tape down the entire length of the heating wire, positioning the tape centrally over the wire.
STEP 3
Follow the instructions supplied with your thermostat. Your underfloor heating system will not function without a correctly installed thermostat.
STEP 4
Check if the heating wire is fully taped and secured. Grout the floor as soon as possible as per the manufacturers’ instructions. Tile as normal, taking care not to damage or dislodge the heating wire.
  • The heater can be installed without the need for specialist tools or expertise (in accordance with local building code). It is important, however, that the Warmup Thermostat be connected by a qualified electrician.
