15. m boards should be laid out in a tessellating pattern similar to the way house bricks are placed in walls The boards can easily be cut with scissors or a Stanley knife and once they are laid out on the floor you should tape the joins between the boards with duct tape or similar The boards should not be secured to the floor base itself Test each mat with a multi meter before unpacking to ensure you have received the product in full working order See the bottom of page 6 for testing instructions You should now roll out your underlaminate heating mats metal side up and place them in accordance with the diagram you previously made The mats should not be bent or twisted and they should lie flat on the floor As you roll out your first heating mat onto the floor continue until you reach an obstruction such as a wall You should now lift up the end of the heating mat and being careful to avoid cutting the cable you should cut through the aluminium foil and clear acrylic from one side of the mat to the other You should ensure that you do this between the correct cable run to allow the mat to turn the way you desire The mat can then hinge back on itself at the point where the green cable now joins the two sections of the heating mat and you can start rolling out your mat in the opposite direction In awkward areas you can cut between a number of the runs of wire on the heating mat to provide you with runs of cable that can be laid out
16. not allow your coldtails to reach the thermostat easily you can re design the system without having laid out a single heating mat Please visit our website www heatmat co uk for further information Installation instructions Floor preparation Ensure the sub floor is solid level and dust free Wooden sub floors can be reinforced using 18mm WPB plyboard Marmox Insulation boards or suitable Tilebacker boards There should be no sharp debris or objects protruding from your base before you begin the installation The sub floor should be insulated to current building regulations however if you are unsure how well insulated your sub floor is Heat Mat can supply 10 or 20mm Marmox Insulation boards Insulation improves the performance and efficiency of your system therefore reducing running costs If there is little or no insulation within the sub floor we would recommend using a suitable additional layer of insulation as well as our Decora insulation If installing Marmox boards these should be secured with flexible tile adhesive onto concrete sub floors or with galvanised screws and washers onto timber bases Reinforcement tape should be used across the joins See www heatmat co uk for further details Installing your earthed Underlaminate Heating system To ensure a completely even floor surface you should cover the entire floor base with Heat Mat s soft insulation board even where no heating is going to be laid The 6m
17. nsider that no mats or heating cable must touch and the coldtail connections and wires cannot cross over any heating cable To simplify your installation the heating mats are provided with 4m coldtails as standard These can be extended by a suitably qualified electrician or alternatively you can cut the heating mat between the cable to provide you with loose sections of the heating wire still affixed to a section of the foil These loose wires can then be laid out effectively extending the coldtail We suggest placing the largest heating mat you have first Start by planning to lay your heating mat from the wall with your thermostat on and run it to the far side of the room You should then return the heating mat to the wall with the thermostat on it parallel to the previous run Continue drawing out the diagram in this method until you have no further linear meters of mat left The coldtail on your heating mat is 4m long So if this is not long enough to return it to the thermostat you will either have to lengthen it or use some of the cable on the mat to return it to the thermostat Remember that if you strip the heating cable from the mat the mat will effectively be shortened You should then design where the next heating mat is going to be placed and we would suggest starting this where the other heating mat finished Continue this process until you have designed you entire floor layout and at this point if you find the layout will

19. pinch the tape so that there are no air pockets beneath it This will help the heat from these areas to spread evenly If you are using a thermostat with a wired floor sensor rather than a remote infra red sensor you should now lay the sensor between two runs of the heating cable in one of the mats To obtain the most accurate temperature reading you should position the floor sensor at least 30cm from the edge of the room in an area where no items will be placed on top of the flooring Cut a channel in the insulation where you wish to lay the floor sensor and line this with aluminium foil before placing the floor sensor on top You should then use a section of aluminium tape to hold the floor sensor in position and this will ensure that the sensor picks up an accurate temperature reading from the floor Finally you should tape down the edges of all of the heating mats and also cover all of the connection wires and the floor sensor wire with tape to protect them during the installation of the flooring If you use a foil tape this will further assist the heat transfer of the system however it is acceptable to use duct tape or similar Now the system is fully installed carry out your electrical checks on each heating mat to ensure that they are in full working order If the heating system is suitably protected with a dedicated RCD at this point then a competent person can turn on the heating system for 10 minutes to ensure that it is h
20. the floor covering and heating system Heat Mat s thermostats are IP21 rated and the heating mats are IPX7 rated which means systems can be installed in bathrooms and other wet areas and if a suitable zone is available the thermostat can also be placed in the bathroom When you first turn on your underfloor heating system after installing your floor covering you should take care to increase the floor temperature slowly over a number of weeks If your floor manufacturer has instructions on the process they recommend please follow these In the absence of any manufacturer s instructions we would suggest limiting the floor temperature initially to 25 C and then gradually increasing this to 32 C over the course of two weeks This process should ensure that the floor does not rapidly heat to too high a temperature which could lead to movement within the floor Although care should be taken with under floor heating when it is used with laminate and wooden floors it should be remembered that laminate and wooden floors are often exposed to high temperatures when they are installed in conservatories without ill effect If you have particular concerns that your floor may suffer from thermal blocking once the heating is installed you should consider using conventional heating mats covered with Thermoplan levelling compound as this compound is very efficient at dissipating the heat that can build up under a thermal block Remember
