Installation of underfloor heating is simple and perfect for DIY renovators. The basic installation steps are here, a more comprehensive guide and instructions will come with your kit.
HOW TO INSTALL
Step 1: Plan the layout of your underfloor heating, make a sketch of the area ensuring the cable mat is free of any permanent fixtures and that the size is correct. Decide on a set-out point, this is where the thermostat will be located. The cable mat will start from this point.
Step 2: Prepare the floor for the installation of the mat, ensure the surface is free of any sharp edges and clean. Where there are jagged edges use a floor levelling compound to level the area.
Step 3: Prepare the electrical connections, this is where the cold tail connects to the wall mounted thermostat, ensure all electrical connections are undertaken by a licensed electrical contractor in accordance with AS/NZ3000 wiring rules.
Step 4: Position the cable mat on the floor starting from the thermostat set-out point. As you roll the cable mat out, cut the red mesh (do not cut the cable) to change directions or avoid obstructions such as drains. It may be necessary to cut away all of the mesh, ensure that the heating cable does not overlap as this will cause excess heat in that area.
Step 5: Fix the underfloor mesh to the floor, this can be achieved by using tape, screws or concrete plugs. Be careful not to damage the blue cable and if working near waterproofing ensure the membrane is intact.
Step 6: Install the external floor thermostat sensor, this should ideally be positioned between the mat blue cables to get an accurate measurement of temperature.
Step 7: Feed the cold tails connection to the location of the thermostat and connect the test monitor. This monitor will allow you to track the condition of the mat during installation and will alert you if the mat is damaged.
Step 8: Let tiles and screed cure for 14 days before connecting and using the heating mat.
