Installation of thin layer heating mats
ECOFLOOR D, DT,DTS,T
Installation of ECOFLOOR mats to the electric net can be performed by qualified electrician
only. Laying of mat into mastic itself and subsequent laying of tiles can be performed by
tiler or investor himself/herself.
It is possible to install more mats ECOFLOOR connected in parallel into one room. It is not
allowed to have series connection for ECOFLOOR mats. Total mat output connected to one
thermostat must not exceed maximum values of the relay output on thermostat.
Condition for granting the guarantee is done plan of laying including marking of connections
of cold and heating cables locations.
There must not be fixed any arrangement objects ( WC, sinks etc. ) in area where the ECOFLOOR
heating mat is installed and also there must not be made any holes ( e.g. for plastic door
stop, WC gripping etc. ).
There must not be put any furniture with flat bottom on the surface. It is possible to use
furniture with feet which enables air circulation and heat removal from the floor.
Control of the mat operation is performed by thermostat ( with floor probe or spacial sensor
).
Installation on concrete
For heat isolation we recommend expanded polystyrene of minimum 25 kg/m3 parameters or
extruded polystyrene.
On the perimeter of the room we make dilatation joint from dilatation belt up to the height of
the floor.
After concreting will exist dilated floating concrete layer ( see chapter Dilatation ).
Because of the dilatation the floor will have better possibility to stretch after heating
without any destruction effects.
Tiles are laid down into a layer of special elastic mastic made for floor heating ( see
chapter Materials for tiles installation… ). Perimeter joint has to be filled with silicone
mastic or special dilatation profiles have to be used ( see chapter Dilatation ). Own mat
ECOFLOOR D,DT,DTS,T installation is being proceeded in accordance with the detailed
instructions for laying ( see instructions on www.fenixgroup.cz ).
Heating mat installation into self-levelling substance
Heating mats can be installed into special self-levelling substances designed for floor
heating, e.g. self-levelling substance MFC Level 350 from Morfico company as following :
- basis ( extruded polystyrene, plasterboard floor, concrete or other material ) will
penetrate with penetration paint according to the floor material.
- heating mat will be put on the penetrated basis in a way that non-heating edges of
individual mat tapes – glassy textile – do not overlap. This procedure proves that there
is a glassy textile of the mat on the whole heated area without any gaps. Glassy textile
creates continuous armature of the self-levelling substance. After consolidation the
self-levelling layer with glassy mat proves much better resistance from cracks. Heating
cables must not overlap or touch each other.
- Needed thickness of layer of self-levelling substance usually moves from 1 to 2 cm.
Maximum thickness of one layer, according to producers of self-levelling substances is usually
1,5-2cm. In case of MFC Level 350 substance from Morfico company it is possible to proceed one
layer at one dash up to 3 cm.
- After consolidation of the self-levelling substance it is possible to glue the tiles.
Sticking ( gluing ) and jointing is being made with elastic adhesive mastics.
