Underfloor Heating Mat

We are custom made underfloor heating mats.

Installation Guidance of Indoor Underfloor Heating Mat 1. Floor Heating Design and Product Selection Step 1: Measure the heated area Determine the heated area of the floor where there are no permanent fixtures or furniture such as showers, toilets, vanities, or cabinets. Measure the heated area of the floor. For example, the total area of the bathroom is 96 ft2. When you subtract the area of the sink, bathtub, shower and toilet, the total heated area is only 74 ft2. Step 2: Determine the power supply voltage The available supply voltages include 120 V or 220 V. Warning NEVER install a heating mat designed for a 120 V power source on a 220 V power source. Important Operating the 220V cable at 120V reduces the power output to approximately 1W/ft. (25% reduction) Step 3: Plan the design Determine the optimum floor heating mat layout for your heated area to ensure coverage. Select a spot for the thermostat in the wall above the heated area where it can be reached by the 8-foot cold lead on the FTM-Mats, and the 10-foot floor temperature sensor. The predetermined FTM-Mats spacing must be maintained to ensure proper floor heating. Do not change the heating mat/cable spacing when you lay out the mat or the floor may have cold spots. 2 installation Important: Tools and materials required You will require the following items to install and test the floor heating system: ·Scissors ·Utility knife ·Wire strippers ·Tape measure ·Screwdriver ·MultimeterYou will also need the appropriate tools and materials to install your particular floor. These will likely include products like self-leveling mortar, thin-set mortar, backer board, tile, a notched trowel, and any other tools for your specific floor. Follow these steps to ensure a successful FTM-Mats Heating System installation. Step 1: PLAN LAYOUT Make a sketch layout or a floor plan of the room; include all permanent furnishings such as toilets, bathtubs, appliances, cabinetry, etc. Indicate all dimensions required to determine the available floor area and the position of the thermostat. Important We recommends that the installation is documented with photos to note the location of connections and the sensor. Step 2: TRANSFER LAYOUT TO FLOOR Draw an outline of the layout on the room floor including a foot print of all furnishings that are not yet installed. Unroll the first few feet of the heating mat. The starting point of the cable must be placed within 8 feet from the thermostat. Using your floor plan determine your desired area of heating mat. Important Minimum distance between the cables must be 10cm(3" or 4"), as applicable. Mark the position of the connection point between the power lead and the mat heating cable. This connection must be concealed in thinset or self-leveling cement. When using a floor temperature sensing thermostat, mark the sensor position in the middle of 2 heating cables, about 10 inch (25cm) away from the wall (within the heated area), as close as possible to the thermostat. Step 3: INSTALL SENSOR If using a floor temperature sensing thermostat, install the sensor now, either in conduit tube, or directly to the subfloor. It is recommended that the sensor be installed in conduit tube. This will allow the sensor to be easily replaced in the unlikely event of failure. The sensor and/or tube needs to be installed between the thermostat wall box and the sensor position. The conduit tube must be partially countersunk into the subfloor. Cut a channel approximately 5/16"deep×5/16" wide in the floor and wall up to the thermostat for the sensor conduit. The conduit has to go from the thermostat and minimum of 25cm/10"away from the wall towards the middle of the floor.Important The sensor conduit must be centered in the cable loop (between two blue heating cables). Use duct tape to close the end of the conduit so that thinset can't penetrate the conduit. Use duct tape to hold the sensor conduit into the groove to prevent it from floating up when the mortar or thinset is poured. If the sensor is installed directly in the mortar bed, use duct tape to secure to subfloor. Step 4: PREPARE SUBFLOOR SURFACE Clean and vacuum the floor thoroughly and remove dust and debris from the floor that may damage the heating cable. Ensure that the subfloor is secure and stable. Carefully fill in all cracks to prevent any potential damage to the new tiles resulting from shifts in the subfloor.Step 5: MEASURE THE RESISTANCE (THE FIRST TIME) Use a digital ohm meter to measure the resistance of the FTM-Mats. Record the measured resistance. Documenting the resistance at each stage of installation is required for warranty purposes. Also, measure the resistance between the blue, brown and shielding/ground wire. Both should read infinity. Step 6: BEGIN LAYING THE FTM-Mats An adhesive has been added to the bottom of the mat which will prevent the mat from moving during installation. Start by placing the mat such that the connection point and the temperature sensor are in their intended positions and bring the power cable to the thermostat or connection box. Begin unrolling the Heating mat evenly across the floor outside the areas that you marked previously. The adhesive on the mat is made such that the mat may be moved several times before it loses its adhesiveness. When you reach the next wall, cut the mesh, turn the mat, and begin rolling in the desired direction. Ensure that the Heating mat is in full contact with the subfloor at all times. Avoid walking on the heating mat. If this is not possible, use shoes with soft soles. When approaching obstacles (toilets, cabinets, etc.), carefully remove some of the heating cable from the mat and lead the cable around the obstacle. In some cases pieces of the mesh will be cut away entirely. Remember to never cut or shorten the blue heating cable. Use hot melt glue or a thin strip of tape to secure the loose cable to the floor. DO NOT CUT OR SHORTEN THE BLUE HEATING CABLE! ENSURE THAT THE SENSOR CONDUIT HAS BEEN PROPERLY INSTALLED BEFORE PROCEEDING (refer to Step 3). It is highly recommended to take photographs of the installed Heating mat before installing the flooring. MEASURE THE RESISTANCE (THE SECOND TIME) Please refer to Step 5. Step 7: Embed the floor heating mat in mortar For tiling applications, proceed with the installation of the tiles by covering the heating mats with a layer ofthinset cement as directed by the tile manufacturer. Ensure that the thinset mortar covers the entire heating mat/cable as the tiles are installed. For engineered wood or laminate floor coverings, it is recommended to consult the flooring manufacturer for maximum temperature allowance (use a thermostat with a floor temperature limiter). Ensure that all moisture in the self-leveling cement has been fully eliminated in accordance with the drying times recommended by the cement manufacturer (consult the manufacturer for exact drying time). Important The system must not be turned on until the thinset cement has fully dried. A minimum of two weeks is recommended. Step 8: MEASURE THE RESISTANCE (THE THIRD TIME) Please refer to Step 5. Step 9: INSTALL THE TILE To install the tile, apply a layer of acrylic or latex modified thin-set using the ridged side of your trowel. Tile and grout the floor using best industry practices and in accordance with instructions provided by the manufacturer of the tile. Step 10: CONNECT POWER SUPPLY AND THERMOSTAT The connection of the power supply and the thermostat must be done by a qualified electrician. The electrician should connect the floor sensor to the thermostat, take the final resistance reading and record it. Note: You need to mark the appropriate circuit breaker reference label indicating which branch circuit supplies the circuits to those electric space heating cables. Step 11: MEASURE THE RESISTANCE (THE FOURTH TIME) Please refer to Step 5. Step 12: ENJOY THE COMFORT OF FTM-MATS HEAING SYSTEM The FTM-Mats heating system is now ready to use. Increase the floor temperature gradually and adjust it until it reaches a comfortable level depending on the type of room and your personal preferences.
