Do not damage the heating element please check the sizing guide to ensure that you have the correct heater(s) for the area you wish to heat. Your warmtech undertile heating element is one continuous resistance wire with electrical conducting wires connected to each end. It must not be cut, shortened...

Technical notes to fully utilize the long-term durability of your tiles, whether heated or not, it is important that the design and construction of the sub floor is carried out correctly. The sub floor must be sufficiently rigid to support the ultimate weight that it will have to bear without moveme...

1. Work out the actual sqm to be heated (see grey shaded area) i.E. 3.53sqm. 2. Divide this figure by the length of the wire to be used per the sizing guide 3.53m 2 ÷ 41.5m = 0.085. 3. Multiply this figure by 1000. 0.085 x 1000 = 85mm apart is your wire spacing. Summary: 3.53m 2 41.5m of wire = 0.08...

Step 1 – floor preparation as a general rule if your floor has been suitably prepared for tiling then it will be suitably prepared for undertile heating. If the heater is being fitted to a solid concrete floor, it is essential that the concrete is fully cured (as per manufacturers specifications) be...

Steps 2 and 3 – mark the floor for element position calculate in square metres the actual size of the area to be heated. Then, using the sizing/calculation guide on pages 6 and 10, establish the actual element spacings. Using a fibre tipped pen mark a start point no further than 1.50m from the power...

Installation step 4 and 5 – lay out heating element and secure with fixing tape. Gently unroll the power supply cable from the spool. After 3 metres of black cable has been removed, you will reach the point at which the power supply cable joins the heating element wire (which is of a different colou...

When you have completed about 90% of the element layout, gently unroll the remaining wire and the second power supply cable (black) from the spool. At the end point where the power supply cable meets the heating element you will find another join. Tape this join to the end point (which is the second...

This is quite acceptable provided that: a. The element is spaced at least 50mm apart at all times. Not closer. B. The element should never cross over. C. Never allow the heating element to be within the wall cavity, the black ‘power supply leads’ only. Once the laying of the element is complete mean...

Installation step 6 – cover the heating element with thermal screed installation step 7 – testing of the heater (prior to and during tiling/tiling procedures) fit the power supply cables into the channels and secure with fixing tape. Remove all debris and chippings from the floor. Check the subfloor...

Installation step 8 – connection and testing of the continuity alarm ensure that the batteries are correctly installed. Test by turning the switch to the on position and ensure that the audible alarm sounds. If the alarm sound cannot be heard, please call 1300 138 126 for technical assistance. Turn ...

Installation step 9 - tiling the tile adhesive and grout should be suitable for use with underfloor heating. For further information refer to the technical notes section on page 9. Where possible when tiling, gently comb the adhesive in straight lines in the same direction as the runs of the heating...

Installation step 10 – controller connection grout the floor as soon as possible as per the adhesive manufacturer’s instructions (extra care should be taken when cleaning between the tiles prior to grouting). Do not switch on the heater until the tile adhesive has fully cured (7-10 days). Once the h...
