Instructions

This product is Under Tile Heating and not In Screed Heating.
If you are looking to install a screed over the element you will need to contact your place of purchase to exchange this product.
You can lay a thin self leveller over the element if required but it should not exceed 5 mm in height.
Please read the instructions prior to your installation: The incorrect installation of the heating element may lead to damage and would invalidate your warranty

GENERAL:

1. The heating mat must only be installed as per the Hotwire instructions.
2. The heating mat MUST NOT be cut or shortened or the cold tail join be put under any strain
3. In accordance with the local electricity laws an authorised electrician must carry out all prescribed electrical work.
4. Your Hotwire element is classified as an electrical appliance. All electrical connections including the connection of the thermostat must be undertaken by a licensed electrician.
5. IMPORTANT: A certificate of Compliance (COC) must be issued by the electrician once the installation has been completed. Your electrician may need to check and test the mat installation prior to any floor covering being laid including the screed.
6. The design wattage for Hotwire mats is 150 watts per m2.
7. The mat width is 450mm wire to wire.
8. Subfloor: It is essential that the subfloor is sufficiently rigid to support the heating elements and not allow unnecessary movement.

FLOOR PREPARATION:

1. Floors must be entirely clean, dry and level. If necessary sand or grind the floor first. Clean working surfaces will provide good adhesion.
2. If a timber subfloor is being used, then we recommend tile and Slate underlay being installed prior to the elements to give the floor the rigidity required. This is especially important if the subfloor is tongue and groove flooring.
3. Water proofing membrane requirements are determined on installation methods and are subject to local council requirements/regulations.
4. Where there is no water proofing, the floor must be painted with primer and allowed to dry for 30-40 minutes. This will ensure good adhesion for taping down the element.

MARKING THE FLOOR FOR MAT INSTALLATION:

1. Mark the floor with a marker pen or crayon to show the exact area to be heated. Be sure not to lay elements in areas that may have floor fixtures installed after tiling (vanities, showers, toilets, and doorstops etc) The minimum spacing between 2 runs of the mat is 50mm and the maximum should be no more than 80mm to achieve efficient heat  distribution.
2. Calculate the exact “net m2 heating area” based on your floor plan Eg: 4m2 = 600 watt heating mat. When measuring the net floor area, measure off the walls, benches and shower trays the distance you require.

PRIOR TO THE INSTALLATION OF THE ELEMENT:

1. Before starting, use a multi-metre to check the resistance on the cable ensuring  there is a circuit. Note the correct ohms reading (-5 + 10%) which is labelled on each cable outer packaging.

2. Prior to starting your installation, a flush box needs to be prepared for your thermostat, Then chisel or cut out 2 short channels in the subfloor at 50mm spacing. These channels are to accommodate the black joins of the cold tail, and the temperature sensor from the thermostat. This will minimise their height and create a flat surface for tiling.
   Note:
   The Thermostat that comes with the Kit is vertically mounted. The heating element  must be protected by an RCD with a ratedresidual operating current not exceeding 30mA. An electrician must either install a dedicated RCD or use an existing one.

3. Plan your laying path in advance, starting directly below your flush-box position. Where you start is where you finish.

4. You can lay the mat in any configuration you want as long as the spacing is even over the total area to be heated. See examples below.

INSTALLATION OF THE ELEMENT:

1. Secure the heating element using a hot glue gun or tape. Make sure no part of the element lifts from the floor surface. This will ensure no damage occurs while screeding or tiling. The use of a spray adhesive along the areas where the cable loops acts as a primer for the tape which will also ensure no lifting occurs.
2. Once you are about 50% through the installation of the heating mat, it is recommended to unroll the remainder of it to ensure you are on target with your initial laying calculations.
3. The mat must be turned when reaching an end wall. To do this cut the tape / mesh from the mat nearest the wall, and turn the mat and place parallel to the existing lane. (Ensure even spacing between lanes is maintained.)
   Note: If you have excess element remaining, you may go back and uplift a percentage of the mat, cut the tapes / mesh then free spool the extra element out across the floor. Never cut the cable (shorten) and remember that the spacings should be kept as even as possible. Test the element again to ensure correct ohms reading after installation and prior to any screed being laid.

FLOOR PROBE (SENSOR) & COLD TAILS:

1. Recess the probe flat onto the floor approximately 50mm from the heating element. This is to ensure that it obtains the correct temperature readings. Use hot glue to hold it in place. The Thermostat sensor should be run in a conduit so it can be easily replaced if required. Warranty claims on probes will not be accepted if not laid in a conduit.
2. The probe wire must NOT cross over the heating element.
3. Ensure that there is enough probe wire to go up to the controller with the cold tail.
4. Attach a draw wire to the ends of both cold tail as well as the floor probe wire.
5. Gently pull up inside the wall so that the cold tail and probe wire can reach the flush box.
6. NEVER allow the heating element to be within the wall cavity.
7. Tape the cold tail to the flush box to avoid them dropping back down inside the wall.
8. Attach the continuity tester included in the kit to the cold tail of the element as per the instructions. This will ensure that any subsequent work on the floor will be monitored for damage.
9. Prior to tiling AVOID ANY UNNECESSARY foot traffic on the element. If the floor is not being tiled /screeded immediately, a sheet of cardboard should be laid over the element as an interim measure.

DO’S AND DON’TS:

Do’s

1. Read the installation instructions prior to the installation.
2. Ensure the surface is clean and clear of obstructions
3. Plan the heat mat layout prior to installation.
4. Pre-plan post drilling Eg: doorstops vanities etc to eliminate damage to the element.
5. Before starting and after laying use a multi-metre to check the resistance on the cable ensuring there is a circuit.
6. Ensure that all heating element is positioned on the floor and not up into the wall cavity.
7. Protect the element prior to tilling
8. Check the element again for resistance readings prior to tiling starting and when tiling be very careful not to damage the element.
9. Use Tile adhesives and grouts that are suitable for use with underfloor heating.
10. Ensure that each tile is solidly bedded in adhesive with no air gaps.
11. If you are unsure of any aspect of the installation or the suitability of the subfloor to be heated, check with your supplier (place of purchase) or call 0800 HEATING for technical advise.

Don’ts

1. Don’t cut or attempt to shorten the element
2. Don’t commence installation on concrete floors that are not fully cured
3. Don’t allow the heating element to cross over or touch – nor cross over into another room.
4. Don’t allow the element to be installed on irregular surfaces.
5. Don’t commence tiling before checking the continuity tester is working and that it is fitted to the elements cold tails.
6. Don’t turn on the heating until the adhesives has fully cured (7 days)

ELECTRICAL SPECIFICATIONS OF HEATING MATS:

TILING INSTRUCTIONS:

1. Always use a flexible adhesive.
2. We recommend the use of a notched trowel and if possible a plastic trowel.
3. To eliminate the risk of damage to the heating cables, you may choose to apply a self levelling compound (screed) Ensure that levelling compounds are used as per the manufacturers instructions. (In particular for non-concrete floors)
4. A cement based grout should be used with no less than 10% latex content. (Latex modified acrylic, PVA,SBR)
5. Always move your trowel in the same direction as the heating elements
6. Use sufficient adhesive to eliminate voids or hollows under the tile.
7. Be careful when removing excess adhesive when scraping between tiles.

AVOID THE FOLLOWING:

1. Cutting tiles over the heating elements
2. Dropping tools or sharp objects onto the elements
3. Don’t wear hard soled shoes.
4. When lifting misplaced tiles ensure that you DO NOT lift the heating cable.
