Schlüter®-DITRA-HEAT-E-DUO-S are complete sets for electrical heating of floor and wall coverings. They contain the uncoupling mats Schlüter®-DITRA-HEAT-DUO-MA (0.8 x 1 m), the heating cables Schlüter®-DITRA-HEAT-E-HK, and the touchscreen thermostat Schlüter®-DITRA-HEAT-E-R or the WiFi touchscreen thermostat Schlüter®-DITRA-HEAT- E-R-WIFI. Thanks to its special anchoring fleece, the uncoupling mat not only reduces impact sound, but also facilitates a quicker heat-up response. If necessary, the uncoupled area can be expanded with additional Schlüter®-DITRA-HEAT-DUO membranes. Please see the attached image on the left to see how the 200w/m2 heated area compares to the 136w/m2 heated area and how many mats you will get in each kit size.
