Underfloor Heating Installation
As with all electrical underfloor heating systems, certain procedures must be followed. Ensure you have read all technical specifications and you are happy to fit Warmup Underfloor Heating to your room. To install your Warmup underfloor heating system follow these five steps. Please note that this is a summary.
STEP 1: APPLY PRIMER
1. Smooth, clean and dry the subfloor
2. Paint the floor with Warmup Primer
If fitting to a wooden floor, the floor must be fitted with tile backer board or plywood.
If fitting to a solid floor the concrete must be completely dry.
3. Allow primer to dry
1. Mark the heater position on the floor
Use the Sizing Guide (found in the back of the Installation Manual) to correctly fit your heating wire into the space provided.
2. Mark the start point
3. Mark perimeter and spacing intervals
Join the corners to form a marked out perimeter.
Mark the spacing intervals for the underfloor heating wire.
Remember: Plan the heater layout and installation so that any drilling after tiling will not damage the wiring.
STEP 3: LAYOUT THE WIRE
1. Gently pull the black power supply cable from the box
After 3 meters, you will reach the point at which the power supply cable joins the heater wire.
Tape to the floor at the start point and at each corner
2. Layout the heater wire in parallel lines
3. Secure the ends of each run
4. Find the other end
At the end where the power supply cable meets the heating wire you will find another joint. Tape this to the end point at least 50mm from the start point.
You will be left with unsecured heater wire – layout in reverse order, starting from end point.
5. Tape down the entire heater
6. Fix power supply cables.
If necessary, chisel out channels for power supply cables and the floor probe wire – this will minimise the increased height.
Fit the power supply cables into the channels and secure with fixing tape.
Remove all debris and chippings from the floor.
Remember: Protect the heater wire with cardboard or hardboard between installation andtiling.
Follow the instructions supplied with your thermostat. Your underfloor heating system will not function without a correctly installed thermostat.
STEP 5: TILE AND GROUT
1. Check the heater wire is fully taped and secure.
2. Tile as normal, taking care not to damage or dislodge the heater wire.
If tiling with mosaic or similar tiles, it is advisable to cover the heater element with latex self-levelling compound before tiling.
When using a notched trowel, gently comb the adhesive in straight lines in the same direction as the runs of the heating wire.
DO NOT lift tiles once the adhesive is dry, as this will damage the heater wire.
3. Grout the floor as soon as possible as per the manufacturers instructions.
DO NOT switch on the heater until the tile adhesive is fully dried (minimum 7 days).
Remember: Use ceramic tile adhesives and grouts are suitable.
Check the floor heater is working directly before commencing tiling.
