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 without the bath, shower, toilet, washbasin and any units -10%.
In a kitchen the FREE area is the floor area without the kitchen units and appliances -10%.
Select the size of the mat below the actual FREE area available e.g. if the FREE area is 7.6m² you should select a 7m² pack, for 4.2m² a 4.0m² pack and so on.
Ensure 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.
