How Do I Choose the Correct Size of ThermMAT for my Installation ?
Plan the installation. Draw a general view of the room and mark the area which will be covered with heating elements. Take measurements of the room. Avoid heating under units and sanitary ware as this can cause heat blockage and it is unnecessary to heat these areas anyway. Always start by measuring the FREE floor area available to apply the heat. In a bathroom the FREE area is the floor area LESS the bath, shower, toilet, washbasin and any units. In a kitchen the FREE area is the floor area LESS the kitchen units and appliances. Select the size of ThermMAT below the actual FREE area available e.g. if the FREE area is 7.6m you should select a 7m pack, for 4.2m a 4.0m pack and so on. In each case check that the mat will fit into your room as it is not possible to cut the heating element. Bear in mind to leave a minimum 50mm unheated gap around the room perimeter when calculating the heated area.
