The following example illustrates this process, with Keraflex Super thin-set mortar, a 1/4" x
1/4" x 1/4" (6 x 6 x 6 mm) trowel for installing
Mapeheat Membrane, plus filling the
membrane and installing the tiles with a
1/2" x 1/2" x 1/2" (12 x 12 x 12 mm) trowel.*
In this example the total floorspace requiring
coverage is 250 square feet (23.2 m2). To
determine how many bags of Keraflex Super is needed to install tile over Mapeheat
Membrane, we need to add the amounts from three separate calculations:
a) Installation of Mapeheat Membrane with a 1/4" x 1/4" x 1/4" (6 x 6 x 6 mm) trowel (with Keraflex Super):
At the per-bag minimum coverage of 100 sq. ft. (9.29 m2),
b) Filling of Mapeheat Membrane (with Keraflex Super)
At the per-bag minimum coverage of 60 sq. ft. (5.57 m2),
c) Installation of tiles (with Keraflex Super)
At the per-bag minimum coverage of 50 sq. ft. (4.65 m2),
Total = 12 bags of Keraflex Super

* Note that the amounts of coverage for each recommended trowel are available on the Technical Data Sheets of MAPEI's thin-set mortars.
When going over membranes, check the Technical Data Sheet of the thin-set mortar for proper water ratios, as
additional water may be required.
No, only one sensor is to be connected to the thermostat. We do recommend installing a second sensor in the floor and running its wires into the junction box, but not connected to the thermostat. The spare sensor is necessary in case of failure of the first sensor.
Yes, you can control the Mapeheat Thermo Connect thermostat with devices enabled by Google Assistant, Alexa and IFTTT.
No, cutting the cable will cause the cable to fail and will also void the warranty. If too much cable is left, you need to install it in a buffer zone or re-install the cable closer to the perimeter of the heated area.
