Schluter DITRA-HEAT-E-DUO-S Thermal Backed WIFI Underfloor Heating Kits

Schluter Ditra Heat Duo with WiFi is a complete underfloor heating kit that contains the complete set of Schluter Ditra Heat Products; the Schluter Ditra Heat Duo Uncoupling Mat, Schluter Ditra Heat E HK electric heating cable, and a Schluter Ditra Heat E R Wifi touchscreen thermostat. The Schluter Ditra Heat Duo WiFi Kit is quick and easy to fit – the Schluter Ditra Heat Duo Kit uncoupling membrane is supplied in a number of rectangular mats measuring 0.8m x 1m. These mats are adhered to the substrate using a tile adhesive. The heating cable can then be installed in the matting in the exact area that you want to heat, then connected to the thermostat. When this is done, the tiles can be laid straight on top of the entire installation using tile adhesive.

The Schluter Ditra Heat Duo Uncoupling Mat is a polyethylene uncoupling membrane with a cut-back stud structure and a 2mm anchoring fleece laminated to the underside. The Schluter Ditra Heat Duo Membrane is designed to work as an uncoupling, crack bridging, waterproofing and vapour pressure equalisation layer that is able to carry the Schluter Ditra Heat E HK Heating Cable. The special thermal barrier fleece reduces impact sound and enables faster heating. This integrated heating cable matting negates the need for a separate heating mat, reducing floor height build up and costs. It can be used on walls and floors, and is suitable for use on unstable substrates.

The Schluter Ditra Heat E HK is an electric heating cable with a unilateral connection for installation in the uncoupling matting. Spaced at 3 studs apart, it produces a heat output of 136W/m², suitable for both floors and walls. Spaced at 2 studs apart, it produces a heat output of 200W/m², suitable for walls. It connects directly to the Schluter Ditra Heat E R WiFi Thermostat – a touchscreen thermostat with a backlit display that features adjustable timer programs, selectable room settings and is compatible with European integrated switch clusters. It measures 5.5cm x 5.5cm and is WiFi-Enabled – meaning you can control the heating via your smartphone with the dedicated Schluter Heat-Control App for IOS and Android.

How to install Schluter Ditra Heat Duo with WIFI Underfloor Heating Kits

Sensor & thermostat position

Please note: When installing Schlüter®-DITRA-HEAT-E in wet environments such as bathrooms and wetrooms, the placement of the thermostat needs to be in line with UK regulations for 230v supply.

Positioning the sensor:The sensors are installed directly in the newly installed Schlüter®-DITRA-HEAT uncoupling membrane. The sensor should be placed in the floor between two heating cables while ensuring the sensor is not placed next to the cold leg of the heating cable - see heating cable label for hot and cold side. Both sensors should be installed, one connected to the thermostat, and the second sensor as a spare positioned behind the thermostat for future connection incase the primary sensor ever fails.

Matting installation

Cut sections of Schlüter®-DITRA-HEAT/-DUO to size and fully embed the anchoring fleece into the adhesive using a 6 x 6 mm notched trowel. Immediately press the material into the adhesive with a float or roller. Work in a single direction, and observe the curing times of all materials. When installing rolled materials, it is best to align the studs of the Schlüter®-DITRA-HEAT/-DUO with light tension at the time of embedding the material. The individual membranes should be aligned next to each other with the stud structure lined up.

Important: Testing of the heating cable, must be carried out prior to installation, and again after installation of the heating cable and before tile/stone floor finish is installed. To test the resistance of the heating cable use the Schlüter®-DITRA-HEATE-CT cable tester with inbuilt alarm.

Floors: To prevent damage or detachment from the substrate, it is recommended to use walking boards (especially in the centre of the assembly) to protect the installed Schlüter®-DITRA-HEAT/-DUO membrane from mechanical impact. The heating cables can be installed immediately after adhering the uncoupling membrane Schlüter®-DITRA-HEAT/-DUO; the heating cable should be installed and pressed into position using a float. We recommend that a groove is prepared in a stud of the Schlüter®-DITRA-HEAT/-DUO membrane to position the heating cable end.

Walls: It is recommended to adhere the Schlüter®-DITRA-HEAT-MA/-DUO-MA mat to the wall with suitable tile adhesive and allow to set. Installation of the heating cable can begin once resistance has been checked and the matting is bonded to the substrate. Once the cable is secured and dependent on the tile or stone covering it may be necessary to in-fill the top of the mat with tile adhesive and allow to set, then comb out adhesive and install tiles.

Heating cable installation

Floors: The stud spacing of the uncoupling membrane is 3 cm. Heating cables should be installed with a distance of 9 cm (every third stud); closer spacing is not permissible. We also advise that the heating cable should be no closer than 60 mm (2 studs) from any building element, e.g. wall, column, bath, toilet, etc. The heating cable should not cross.

Walls: The stud spacing of the uncoupling membrane is 3 cm. Heating cables should be installed with a distance of 6 cm (every second stud) or 9 cm (every third stud); closer spacing is not permissible. We also advise that the heating cable should be no closer than 60 mm (2 studs) from any building element, e.g. wall, column, bath, toilet, etc. The heating cable should not cross.

Heating cable testing

The transition from the heating side to the cold connection cable (sleeve) is labelled as shown the transition must be installed straight within the matting (not installed curved around a stud). This cold side of the heating cable is 4 metres in length and can be connected directly to the thermostat or junction box. The minimum cut length is 1 metre from the label on the cold side.

Important: Testing of the heating cable, must be carried out prior to installation, and again after installation of the heating cable and before tile/stone floor finish is installed. To test the resistance of the heating cable use the Schlüter®-DITRA-HEATE-CT cable tester with inbuilt alarm.

We recommend an insulation test is carried out prior to the embedding of the heating cables to measure the resistance of the heating cables. Once the heating cables have been installed and tested, tiles can be installed in the thin bed method, using a thin bed adhesive that meets the requirements of the tile covering. Use a grout float to fill the grooves of the uncoupling membrane in a single step (heating cables and sleeves must be fully enclosed with tile adhesive) and then use a notched trowel to apply the adhesive. A minimum 5mm of covering (adhesive and tiles) is required above the heating cable.

Important: The assemfly should be left for a minimum of 7 days before turning on the electrical heating system.
