DESIGNING FLOOR HEATING AND CHOOSING THE PRODUCT

Pre-installation planning

1. Assess the surface to be heated
   Define the surface to be heated by leaving out the territory covered with fixed sanitary devices (shower, toilet, bathtub, kitchen cupboard, etc.) Calculate the size of the surface to be heated.
   For example, the bathroom shown in Figure 2 is 8.75 m2. When deducting the area covered by the shower, toilet, and sink, the remaining area is only 6.45 m2. Choose the 6 m2 size heating mat with the competent capacity.

2. Check grid voltage and available capacity
   The system operates using 230 V grid voltage. Check the available capacity, and request an extension from the provider if necessary.

3. Design the system
   Plan the optimal placement of the heating mat with full coverage. When defining the place of the thermostat, take note of the 2.5-meter-long connection cable of the heating mat required to reach the thermostat, as well as of the signal transmitter of the thermostat on the floor to be an adequate distance. It is advised to lead/install the connection cable of the heating mat from the place of the thermostat. See Figure 3.

Important information

To ensure even heat distribution, keep cable distance as set by default during installation.
By increasing cable distance, cooler floor areas may be created.

INSTALLATION

Important information: Tools needed for the installation
You will need the following tools for the installation and check-up of the heating system:

• Scissors
• Tile cutter
• Cable stripping tool
• Measuring tape
• Screwdriver
• Electric measuring device/multimeter

Make a drawing of the layout
Make a drawing or sketch indicating the planned layout. Indicate every area covered by fixed sanitary and other devices (shower, toilet, etc.) Calculate the size of the surface to be heated. Write down all the needed size data for the surface to be heated, and define the place of the thermostat and the floor sensor.
Copy the drawing onto the floor

Draw the outlines of the planned system on the floor. Leave out the places of devices to be placed as fixed later. Roll out and place the first couple of meters of the heating mat. The starting point of the cable should not be more than 2.5 meters away from the thermostat.

Important information

Make sure that the connection point (connection cable – heating cable) of the BVF H-MAT cable is placed in a conduit. Placement of heating cable in the conduit pipe is prohibited! Only the connection cable shall be put through the conduit pipe.
Make sure to place the floor sensor of the thermostat exactly in between two heating mats (on a heated surface), at a distance of at least 65 cm from the wall, in a conduit pipe, to enable replacement if necessary.

Installation of the sensor
Place the thermostat’s floor sensor lead in a conduit pipe. It is advised to use a conduit pipe to enable easy replacement in the unlikely case of malfunction. The thermostat’s floor sensor and conduit pipe shall be led to the wall module box of the thermostat. The conduit pipe shall be partly encased in the floor.
Important information

Make sure to place the floor sensor of the thermostat between two heating cables, at an equal distance. Secure the end of the conduit pipe using adhesive tape to prevent floor leveling compound or tile adhesive from getting to the sensor. Secure the conduit pipe as well to avoid floating. When placing the sensor directly into the tile adhesive, fix it to the floor as shown in Figure 3.
Preparation of the subfloor
Clean or vacuum the subfloor removing all kinds of contamination which may damage the cable. The pre-installation manual presents the method of preparation in detail.
Check the flatness of the floor. Fill in any gaps or uneven parts to prevent cable damage.
Read system resistance (1st time)
By using an electric measuring device, carry out a resistance reading (between the blue and brown terminals) and compare the data with the values shown in the table (Section 3.2). Record the date on the Warranty Card. Recorded resistance values may be required during later eventual warranty issues. Then, read the resistance between the blue, brown, and the grounding, which should show an open circuit reading. For more information on resistance, reading see Chapter 5.

Placement of the heating mat
NEVER CUT OR SHORTEN THE HEATING MAT!
The bottom side of the heating mat contains adhesive, which shall secure the mat on the floor during placement. Begin the placement in a way that the connection cable and the sensor are put in their places when starting the placement. Lead the connection cable and sensor cable to the thermostat’s connection point.
Install the heating mat evenly on the previously marked places. Prior to applying the adhesive, you can replace the mat before final fixing. When reaching the wall, cut the net, and turn the heating mat in the needed direction.
Make sure that BVF H-MAT is directly fixed to the floor on the entire surface. Avoid stepping on the placed heating mat. If it is inevitable, use smooth bottom shoes. Should you experience heating cable floating, apply a thick adhesive or glue tape on direct points.
When reaching different obstacles (shower, toilet, etc.) carefully remove the heating cable from the net and lead the cable around the obstacle. In some cases, partial or full removal of the net may be necessary. Remember that cutting the cable is prohibited! Use adhesive or tight glue tape to fix the removed cable on the floor.

Important information
It is advised to take a photo of the system prior to covering it.

Read system resistance (2nd time) in accordance with Section 5.
Covering

Prior to covering check the fixing of the thermostat’s floor sensor (as in Section 3.).
When placing the ceramic cover, apply a thin layer of tile adhesive and proceed according to the producer’s instructions. The tile adhesive shall fully cover the heating cables.
Important information

Do not activate the heating system before the full dry-out of tile adhesive. This shall take a minimum of 2 weeks.

Read system resistance (3rd time) in accordance with Section 5.
Placing the cover

Place the cover in accordance with the instructions provided by the producer.
Connection of the thermostat and electricity
Assign an electrician to carry out the electricity and thermostat connection. Following connection, read the resistance for the last time, and record the values on the Warranty Card. See Section 13.
Note: Mark the circuit-breaker of the heating system on the switchboard.

Read system resistance (4th, last time) in accordance with Section 5.

HEATED FLOOR/COVER

1. Ensure the electric floor heating’s steady heat radiation, and avoid placing sizeable objects/furniture without legs on the floor.
2. Avoid covering the floor with materials having high thermal insulating qualities (thick rug, mattress, under-bed bin, thermal proof materials, etc.) during operation.
3. Protect floor covering from moisture, and long-term wetting.

CONTROL

1. Calibrate the thermostat using a room thermometer, since default settings of any type may be different than the actual temperature. (For details see the User Manual of the actual thermostat)
2. In case of individual heating, place the sensor operating mode of the thermostat to double (floor+room) position, where the thermostat shows the air temperature based on data provided by the built-in sensor, and the floor sensor sets the limit temperature of the floor (heat sink) in the value of the set temperature.
3. Set the disabled temperature of the floor sensor to 29-31°C. (For details see the User Manual of the actual thermostat)
4. If the system is equipped with a programmable thermostat, for the most efficient operation the use of programming functions is advised.
5. BVF H-MAT floor heating system is NOT a heating storage or partly heating storage system, thus shorter heating-up times shall be taken into consideration when starting and programming heating cycles. Heating up, depending on the floor’s original temperature and thickness (thermal storage capacity/thermal inertia) may take a longer time.
6. During the heating season, for the best results, avoid turning off the heating system, when out of use set the air temperature back by 3-4°C the maximum, thus preventing the overcooling of walls and other devices. In case the heated premises are to be out of use for a longer period, the use of the anti-freeze program option is advised for conservation purposes.
