Installing your Enerfoil Underfloor Heating System

• Download Enerfoil Underfloor Heating installation instructions.

The Enerfoil Underfloor Heating System can be installed in any area where the ceramic floor tiles require to be heated for comfort. Before attempting to install the system read The following instructions. If in doubt contact your system supplier for further advice.

1. Ensure that the floor area on which the panels are to be laid is flat and free from sharp edges or projections. On wooden floors make sure that there are no nail heads protruding and it rough, sand to a smooth finish. Tongue and groove floors should be covered with plywood of minimum thickness of l5mm firmly secured at 300mm centres. Floors should be free from grease and contaminants. Concrete floors which do not have a floated finish are uneven or have protrusions should be smoothed with BAL-MULTIBASE.
2. Lay the panels flat on the floor and position them to ensure that they cover the required area. (Fig A) Each panel section is supplied with power cables at approximately 3.0 metres attached during manufacture. Panels should be positioned such that the power supply cables are all located along one edge of the room to facilitate connection to the power transformer. Note! Under no circumstances should the panel sections be cut or modified in any way as this will affect the electrical continuity and affect their effective operation. Maximum side overlap not to exceed 70 mm.
3. In areas where continuous floor temperatures are required. care should be taken to avoid gaps between adjacent sections.
4. Before setting out the panels. identify a suitable location for the transformer. The transformer should be located on a secure foundation in a dry, ventilated environment and never exposed in a bath or shower room. Care should also be taken to plan the cable runs both for the 230v ac supply to the transformer and the 24I28 v ac supply from the transformer to the panels. In the event that a number of panel sets are to be installed in parallel it will be necessary to use a suitably rated junction box. Maximum number of wires to be inserted into one terminal of transformer is 3.
Do not reduce the wire thickness as this will effect performance of the foil.
5. Before laying the panels, check the electrical continuity of the panel sections by connecting a suitable multimeter across each pair of feed wires. The resistance of each panel section should be in the range shown in the technical specification section. Record the readings. 6. Prepare the surface to receive the panels (Fig B) by applying the BAL-ENERBOND with a vinyl spreader in accordance with enclosed instructions (Fig C).
7. Allow the adhesive to dry for 5 mins until tacky before placing the panels onto the adhesive. using a rubber float, with a sweeping action from the centre press the foils into the adhesive ensuring that there are no air bubbles or ripples. 8. The panels should be primed using a coating of BAL- ENERBOND prior to laying the ceramic tiles. (Fig D.) Allow the priming coat to cure until it does not come away from the foil when touched by hand. Check the resistance of the foil.
9. The ceramic tiles should now be fixed in place using a suitable flexible floor tile adhesive such as BAL-FASTFLEX or BAL-RAPIDSET FLEXIBLE floor tile adhesive. 9 (Fig E) Normal floor tile fixing techniques are suitable for tiling over Enerfoil systems )Fig F) details of which can be obtained from the BAL Technical Advisory Service. Care must be taken to ensure that the panel sections are not damaged during the fixing of the ceramic tiles. Tiles dropped onto the panel sections during fixing may puncture the surface of the heating panels reducing the
operating effectiveness of the installation. Check the resistance of the toil before grouting. Grout the tiles using either a flexible cement based tile grout or an epoxy grout and finish in accordance with normal tiling practice. Do not attempt to connect the Enerfoil system to an electrical supply until the adhesive and grout have been allowed lo cure fully (normally at least 48hrs).
10. Before connecting the power cables of the panel sections to the junction box (or directly to the low voltage side of the transformer if less than three sections are being installed) carry out a final continuity check. If satisfactory connect the cables of the panel sections to the junction box Ensure that the cables of each panel section are connected in parallel i.e. black to black and blue to blue. Care should be taken to keep the cables approximately the same length.
11. The junction box should be connected to the low voltage side of the transformer using a suitably rated two core insulated cable. The cable used should be rated for the maximum current to be drawn by the panels and should be selected to provide no more than a 1 V drop at that current. For example, a 6.Omm cable running a 22 amp current from an ENl6 transformer feeding 16 panels will provide a 1 V drop al 15m length (7.5m run of dual cables).
12. Select the output connection required, 24 or 28vac. Connect the black cable to the common or black connection and the blue cable to the 24v or 28v terminal. Check all connections are secure and connect the transformer lo the 230v ac supply. The tiles should begin to feel warm after a few hours. 13 If there is no noticeable heating of the tiles. check the output at the low voltage side of the transformer. It there is no voltage, check the fuse. If tIhe problem persists refer to the system supplier or to Enerfoil Ltd. 14. Following completion of the installation a suitable notice should be displayed in a prominent position warning of the need to avoid drilling or penetrating the floor particularly when replacing or repairing damaged or defective tiles. It is also recommended that an accurate record be made of the layout of the panel sections and any buried wiring for future reference. Comprehensive fitting instructions are supplied with all foils. These must be read before installation.

To establish how much ENERfoil you need:
Measure the room, and create a sketch showing position of doors, radiators,, baths, toilets, cabinets, power supply etc. Experiment with different combinations and layouts of Enerfoil panels to achieve the optimum performance and coverage.

Applications:

Directly  under tiles, stone, marble, slate, wood, laminate vinyl and even carpets.

Under carpets on existing tile- or wooden floors.

Bathrooms

Living rooms

Kitchens

Conservatories

Caravans

Offices

Dog Kennels

Technical data

The Enerfoil system is designed to raise the temperature of the flooring material by generating an even constant heat. The actual temperature maintained will vary according to the ambient temperature, floor covering, insulation and the selected voltage.

The system comprises of a number of manufactured panels which are 600mm wide and come in lengths from 0.5m to 4.0m but always in multiples of 0.5m i.e. 1.0m, 1.5m etc and can be used in different configurations to get the best possible floor coverage. Other widths are available. A low voltage AC current, supplied via a transformer powers the heating panels. The size of transformer is determined by the number of panels used in the installation. The free design service is available for all customers.

Following the instructions contained in the installation sheet will ensure the reliable and effective operation of your ENERfoil Low Voltage Underfloor Heating System.
