Questions & Answers


Will the heating system be able to heat the room sufficiently ?


This depends on a number of factors including room height and insulations levels in floor and walls, but if insulation boards are used (blueboard or Heatstore tile backer boards for tiles – depron or blueboard for wood) then the system should heat the room. The system always works best if used with suitable insulation boards as this prevents the heat from going downwards instead of upwards. We understand that not everyone has the floor height to install a board so in this case you could use Thermacoat thermal paint, which does not raise the height at all.


What wattage do I need?


If you would like to heat a standard room which is well insulated 150 watts or greater is required. If you are heating a conservatory, which is considered high heat loss or a room with lots of fixed furniture such as a kitchen then we suggest 200w. 200w by nature heats up faster than the 150w so if you can use it then you may as well have the most powerful.


What is the maximum wattage per meter square for my room?


Underwood – 140w per meter Under Tiles / stone floors - up to 200w per meter Under carpet or lino - maximum of 150w per meter


How high will the system raise my floor levels?


Our heating cables are 2mm thick, but you need to allow for your tile adhesive (5mm), your tile and any insulation board used.


How wide are the mats?


The mats are 500mm wide and come in different lengths to suit the size of the room you require. For instance if you require a 4m2 mat kit, it would come on a roll of 8m2 long by 500mm wide. This covers 4m2. You roll out the mat and cut it when you reach the end of the room then flip it over and come back the other way.


What is the difference between the heating mats and cable systems?


Heating Mats: Heating mats are the same cable as the loose cable kits (2mm loose heating cable rated @10 watts/m) already spaced out for you and attached to a fully adhesive mesh backing. Our heating mats come in 3 wattages: 200 watts per square meter This is the most powerful type of heating mat. It can be used beneath tiled or stone floors and is recommended for high heat loss areas such as conservatories. It should also be used where laying onto a concrete floor when not using insulation boards. The maximum size of mat on 1 thermostat is 18m2 150 watts per square meter This is a mid-range powered mat which is suitable for most applications which can be used as a primary source of heating beneath most floor finishes. It should be noted that finishes such as Kardean or Amtico have a maximum of 150w per meter. The maximum size of mat on 1 thermostat is 24m2 100 watts per square meter This is the lowest powered mat which is suitable for taking the chill off cold tiles – it is not suitable for a primary heating source. The maximum size of mat on 1 thermostat is 30m2 Heating mats are for use on a finished subfloor such as concrete screed or plywood and we recommend they are encased in either a flexible tile adhesive (if laying tiles) or a flexible levelling compound if laying any other floor finish. Heating Cables: The loose heating cable is rated at 10 watts per linear meter and is the same cable used in the heating mats. The cable comes on a drum and spacing must be manually measured (full instructions on how to do this are included in the kit). In Screed Heating Cable: Must be encased in the finishing screed of the concrete floor (usually a minimum of 65mm as per Building regulations) with a minimum of 20mm of the screed above the cable. The same maximum outputs are recommended for the in-screed cable, that is, up to 200watts/sqm beneath tiles / stone and 160 watts/sqm beneath all other floor finishes.
