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.
It does not matter. Provided that the manufacturer of the flooring products (coverings, adhesives, etc.) says they are compatible with floor-heating systems (always defer to the floor-covering manufacturer’s instructions), the installation is UL-approved.
First, measure the actual heated area, not the total square footage of the room. Do not lay heating cables under cabinets, furniture or appliances.
Next, decide on heat output. When installing Mapeheat Cable with Mapeheat Membrane: A 3-pillar spacing in Mapeheat Membrane produces 10 W per sq. ft. (low output), which is not typically recommended but is acceptable for low-use areas when trying to stretch coverage. A 2-pillar spacing in Mapeheat Membrane produces 15 W per sq. ft. (high output), which is best for installations on a concrete slab or when heat loss is a concern. An alternating pillar spacing of 2-3-2 in Mapeheat Membrane produces 12 W per sq. ft. (standard output).
When installing Mapeheat Cable with Mapeheat Cable Guides: A spacing of 3" in Mapeheat Cable Guides produces 12 W per sq. ft. (standard output). Alternating spacing of 3"/2" in Mapeheat Cable Guides produces 15 W per sq. ft. (high output), which is best for installations on a concrete slab or when heat loss is a concern.
Always default to the lesser square foot on the chart.
In order to access all the wireless features of the Mapeheat Thermo Connect thermostat, you must first connect it to your WiFi network by going into “Settings --> WiFi Settings” and completing the WiFi setup. Once the thermostat is connected to your WiFi network, you will be asked for an email address to begin the setup for your MyMapeheat.com account. An email with an activation link and instructions will be sent to that email address. After your MyMapeheat.com account is set up, you can control your Mapeheat Thermo Connect thermostat via MyMapeheat.com or download the Mapeheat Thermo Connect app from the App Store or Google Play.
WiFi thermostats connect to your home WiFi and enable you to control many of your floor-heating system’s functions, depending on the model. They can be conveniently controlled via the manufacturer’s app for either Apple or Android devices, or from a Web portal on your browser. WiFi thermostat control is limited to setting the minimum or maximum temperature, and activating and deactivating a program. It cannot remotely turn the floor-heating system on or off, but can enable warm-weather shutdown to ensure that your floor-heating system doesn’t run when your home’s outdoor or indoor temperatures rise. With their convenient features, WiFi thermostats are ideal for vacation homes or to track energy usage.
You can install more than one Mapeheat Mat or Mapeheat Cable to a thermostat, provided that the total draw does not exceed 15 amps. The thermostat typically holds up to 3 or 4 sets of leads before fitting the lead wires into the terminals becomes difficult.
Installation of Mapeheat Membrane below luxury vinyl flooring follows the same installation method as engineered and laminate floors: First, embed the floor-heating system within cementitious material, ensuring in 1/4" (6 mm) of coverage above the heating system. Either a mortar or self-leveling compound can be used, but achieving the desired flatness is easiest with a self-leveling underlayment. Proceed with installing the floor covering on top, following the manufacturer’s instructions.
Before removing the heating cable from the packaging, measure and confirm the intended square footage of your heated area. Use the coverage chart on the cable box to determine which cable spacing will yield the desired square footage. Note that consistent spacing between the cable and across the room must be maintained for even heat distribution. If you have too much cable left over, double-check that you have purchased the right cable based on the square footage of the area. If the wrong cable was purchased, contact the distributor to see if a return is possible. Otherwise, install any excess heating cable in buffer zones (such as behind the toilet) or in areas not previously calculated; or, install the cable tighter to the perimeter.
