This is the Danfoss 83020745 DEVImat 7.0 square metres heated area (14m x 0.5m mat dimensions) 1385W Underfloor Heating Self-Adhesive Mat ideal for Concrete Floors DTIF-200T 200W/m2. 

The Devimat DTIF-200 grants you the luxury of warm tiled flooring, letting you bask in the  satisfying warm heat spread evenly across your floors surface. It will leave no significant increase in your floors height, with an ultra thin depth of only 3.5mm.

This is a high output mat, with an impressively warm blast of 200 Watts per m², granting you speedy heating when you need it most. The rapid response time of the Devimat combined with the high wattage output gives it numerous possible usages, combined with a timer control for ultimate IOT convenience.The controller is a Devireg 550, which is an intelligent flush mounted thermostat, that comes complete with a floor sensor, and each part works finely in tandem with each other.

Furthermore, the mat is prefabricated for easy installation, comprised of a self-adhesive open mesh onto which a thin heating cable is attached. Mats are available in a range of sizes for your convenience, ranging from 1-12 metres². 

It is ideal for when you are renovating large areas such as conservatories and cellars, which can lose large amounts of heat, for use in small bathrooms with a relatively small floor area compared to the size of the room. 

DEVImat 200T (DTIF) Underfloor Heating - installation

  • Important notices before you begin installing the DEVImat DTIF: firstly you should not be installing thin mats at temperatures below 5 degrees. Ensure you don’t damage the thin mats with sharp objects. The minimum distance between heating cables, heating cable and conductive parts, heating cable and other heating sources should be at least 50mm. 
  • Your heating cables should not touch or cross themselves, or other heating components.  The heating cable bending diameter must be at least 6 times the cable diameter. Thin mats should not be installed on irregular (for instance very bumpy) surfaces. The subfloor construction should be secured to avert relative movement after installation, and the thin mat must be fully embedded in the screed.
  • When rolling out the mat, check that there are no imminently placed objects that could cause a thermal block, such as furniture, thick carpets and so on. Position the mat so that it is at least half the Centre to Centre (C-C) distance from any obstacles, and that they are in good contact with a heat distributor (e.g. concrete). Roll out the thin mat with the heating cables facing up and ensure that they do not crease the thin mat. 
  • If any additional securing is needed, then hot melt glue, double-adhesive tape or tile glue that could be used. When the thin mat reaches the area boundaries, cut the liner/net and turn the mat before rolling it back up. Make sure you never cut the heating cable under any circumstances.
  • Recommended areas for installation: DTIF-200 is designed for installation in floor constructions of concrete or with tiles and where the heating element is installed close to the floor surface.
