Vysa-Mat Classic Heating Mats

The overall size of the Vysa-Mat Classic heating mats has been optimised so that they closely match the most common room sizes encountered. We offer a wide range of sizes in each power rating to fully allow any area to be fitted – check under the Order Codes tab for details. More than one mat can be installed and wired to a single thermostat.

Their specification is even superior to most others with an IP67 rating that protects the heating cables in the event of short-term flooding up to a depth of 1m of water!

•Vysa-Mat Classic heating mats rated 100W/m2 are generally suitable only for floor warming and comfort heating. However, larger areas in well insulated homes are often heated adequately using 100W/m2 – in well insulated Scandanavian houses they only use 80W/m2!


•Vysa-Mat Classic heating mats rated 150W/m2 can provide primary heating for most medium sized rooms, including conservatories, where sub-floor insulation complies with building regulations

•Vysa-Mat Classic heating mats rated 200W/m2 can provide primary heating for conservatories and all but the smallest rooms in the house. They can also be used in commercial applications especially in high heat-loss areas


We do recommend that Vysa-Pron MAX Tile backer Boards are installed to reduce energy costs and improve warm up times. Without adequate insulation, you are effectively heating the sub-floor and foundations as much as the floor covering.

Easy to Install – The Vysa-Mat range are a combination of a heating cable attached to a fibreglass mesh scrim that can be simply rolled out over the floor saving precious time. The mats have double-sided tape on the underside so that they are easily secured in place on any clean surface.

All the Vysa-Mat range are 0.5m wide and are thus suitable for even the smallest spaces. The mesh scrim can be cut enabling the mat to be turned and laid alongside the first run (the heating cable must never be cut and when laying the second or subsequent run, you must ensure that none of the heating cables overlay each other). Full and detailed installation instructions are always supplied.Diag bathroom hmat

Vysa-Mat Classic heating mats can be installed on top of existing wooden or concrete floors that are sound and suitably prepared. See guidance on floor construction on this website. We would always recommend fitting a layer of Vysa-Pron Max insulated tile backer board before laying the cable mat. This will minimise heat losses and insure quicker heat-up times for the floor.

It is good practice to plan your installation using a sketch marking your laying pattern and planning the position for your floor sensor, connection box and thermostat. You should avoid all floor obstructions like baths, shower trays and floor mounted cupboards. Also avoid any areas where floor fixings may require to be drilled. It is important that you spend time planning your installation as the cable mat cannot be shortened.

Cut a groove in the floor to accommodate the floor sensor for the thermostat. The sensor should be installed in the 10mm diameter flexible conduit supplied with the thermostat. The sensor should be positioned between 2 heating cable loops under the mat approximately 500mm from the wall.

The floor should be prepared as normal for tiling. The entire floor should be swept clean and be free of any sharp projections. The floor should then be primed if required using Vysa-Bond Primer. Before laying the mat, check the resistance using an Ohmmeter and compare against the value marked on the cold tail label. Planning is extremely important at this stage so it is advisable to lay the mat over the surface of the floor without sticking it down to enable you to have a clear ideal of how the mat will be laid.

When rolling out the mat, flip the mat over when you reach the end of a run by simply cutting the backing mat (NOT the orange cable). Turn the mat through 180º and run the next strip adjacent to the first. Please ensure a minimum space of 50mm between cable loops. When satisfied with the proposed layout stick the matting to the floor using integral self adhesive fixing strips. For hard to reach areas the cable can be removed from the mat and attached to the floor uniformly with adhesive fixing tape.

The matting can be further secured to the floor by hot glue gun, staple gun or adhesive tape. This is recommended on the outer edges of the matting when using self levelling compound to prevent the matting lifting. These additional fixing methods should only be used on the matting and not on the cable.

Before and after covering the cable mat with the tile adhesive/self levelling compound the cable resistance should be checked against the label value.

When using tile adhesive it is important to ensure the cable is totally encapsulated to prevent air gaps. The heating cable must not be cut or shortened and the joint between the cold tail (black) cable and the (orange) heating cable must not be bent or put under strain. Orange heating cables should never cross or touch (50mm gap minimum) and must be installed in the room to be heated. Always wear shoes with rubber soles when walking on cable mat and avoid any unnecessary traffic over the area until the cable is completely protected below the self-levelling compound.

A fully qualified Electrician must now make the final connections to the mains supply and install the thermostat. The thermostat should be installed in the room to be heated. For bathrooms the thermostat must be placed outside Zones 1 & 2. Finally the electrician should check the continuity of the floor sensor and retest the resistance of the cable. A further insulation test should be carried out in accordance with IEE regulations. The installation should be protected by an RCD for safe operation. Consult the adhesive manufacturer’s instructions as to be suitable drying out period before turning on the system.

  • Q. Why can I not cut the cable?

    A. Specific cable lengths have been adapted to provide the correct resistance value and therefore the appropriate heat output in W/lin metre. If the cable is cut or shortened, the resistance will be changed and therefore the designed power output will be changed.

    Q. What if the heating mat/cable is too long?

    A. The most crucial part of an underfloor heating installation is the design. Always accurately measure the effective floor area that you want heated and choose the nearest mat size down after subtracting a 10% perimeter allowance. Before installing the mat or cable check the size against the floor. If the mat/cable is obviously too long – Stop. At this stage it is best to return the product for exchange for the correct size as you cannot cut the cable. A small oversize maybe dealt with by reducing the cable spacing but any reduction will have an effect on the heat output (W/m²). Do not cross the heating cable and make sure that the minimum cable spacing distance is 50mm.

    Q. Will my cable mat provide Primary Heating.

    A. If you are considering using underfloor heating as the sole source of heating in your room you need to ensure that you allow for sufficient heat input to cover the heat losses. We recommend that you consult your architect or heating engineer to provide heat loss calculations. As a guide however, if your room complies with the insulation standards in the current building regulations, Vysa-Mat Classic 150 or 200 watts/m² cable mats can be used as a primary heating source. Rooms with potentially high heat losses such as conservatories may require a supplementary heat source on very cold days.

    For your information, mats with higher heat outputs per square metre, do not mean that they will use more energy to run. Heat input is controlled by the thermostat. Rather they provide quicker warm-up times.

    Q. Would I be best with a Cable Kit or Cable Mat.

    A. Loose cable is ideal for installations involving intricate and irregular room designs as the cable provides maximum installation flexibility. In addition cable spacing can be varied to provide more output in designated high use areas around basins and sinks. Heating mats have a set width for installation in regular shaped rooms where they are very quick and easy to lay and provide a regular and even heat output.

    Q. Can I heat a wooden floor using a cable mat?

    A. Yes you can do this but it is not the best solution. We would recommend the use of Vysa-Film underfloor heating element for heating laminate of timber floors. Vysa-Film elements provide a simple dry installation method and is ideal for all floating wood floor installations. It is ultra thin and provides minimal floor height build-up.
    If you must use a cable mat for heating under a wooden floor it must be covered with a minimum layer of 10mm of floor self-levelling compound over the top of the heating cable. This layer acts as a heat dispersion medium so that the heat from the cable is evenly dispersed throughout the surface it reaches the wood or laminate floor covering.

    Q. Can I use my Floor Heating immediately after installation?

    A. NO. You need to give the installation adhesives time to dry out. Consult the information provided by the tile adhesive and/or self-levelling compound manufacturer used in your installation for recommended drying times. Premature use of the underfloor heating to cause accelerated drying of the adhesive can cause micro cracking of the material which could be detrimental to its long term performance.

    Q. Can I join 2 mats together?

    A. Heating mats or cables can be joined together in parallel via a junction box to the control thermostat. Be careful not to exceed the rating of the thermostat (which is 3450 watts). If this rating is exceeded a suitably rated contactor needs to be used in conjunction with the thermostat.

    Q. Can I tile directly on top of my cable or cable mat installation?

    A. Yes you can. There are 2 recommended methods for covering the cable.
    The first is to apply flexible tile adhesive on top of the mat or cable so that it is completely covered, ensuring that there are no air pockets. This should be done using a rubber backed trowel or similar taking care not to damage the cable. Another layer of adhesive can then be applied using a traditional notched trowel to comb the adhesive before laying the tiles.

    An alternative method for all but the smallest installation is to cover the cable/cable mat installation with a suitable latex self-levelling compound. This product will find its own level and once dry will provide a suitable flat surface to apply a layer of flexible tile adhesive before laying the tiles.
