Image titled Install Electric radiant-heat Mat underneath a Tile Floor action 1Prepare your floor for tile by installing tile backer board on the floor, securing it towards the existing sub-floor with thin-set mortar and cement board screws or nails.

Make a scale design associated with the restroom flooring, including lavatory, tub and vanity areas, and take it towards the tile store or house center to purchase the proper dimensions pad or combination of mats. Points to consider whenever sizing the pad tend to be: 1) Install the pad up to the location where in fact the vanity cabinet or pedestal sink will remain, however under it; that can cause exorbitant temperature buildup; 2) Keep the pad 4 in. far from wall space, baths and tubs; 3) keep consitently the mat at the least 4 in. from the lavatory wax band; 4) keep consitently the home heating cable at least 2 in. far from it self. Never overlap the cable; 5) Don’t leave large gaps between your mats. Your feet should be able to inform!; 6) If your pad is undersized, give concern towards the places where you’ll be standing barefoot most frequently.

Install an electrical outlet package 5 feet (1.5 m). up when you look at the wall surface near where wiring leads from the mat will end. Operate brand new wiring on box from circuit breaker panel or - if the mat is small - from a nearby outlet (consult maker's guidelines to find out more about wiring requirements).

Note: following your initial design, you really need to mark the path regarding the thick “power lead” between the mat and wall cavity and chisel a superficial trench to the floor. Notch the bottom dish to accommodate the two conduits that'll support the energy lead while the wires the thermostat-sensing light bulb.

Draw the layout lines when it comes to tile on the ground. Choose tile that is at the very least 6 in. square so each tile will span two or more parts of cable. Smaller tiles are more likely to conform to the minor mountains and valleys of this cable when you tamp them set up, producing a wavy area.

Don’t leave any humps or free sides; you’ll snag them with your notched trowel whenever you’re applying the thin-set mortar. [NOTE: This set up reveals an open sort of mat that is mortared and tiled in one action. Other forms of radiant-heat mats must certanly be mortared positioned first, permitted to dried out, and tiled. Follow the manufacturer's directions.]

Look at the mat wiring once more aided by the continuity tester.

Install conduit connectors to both ends of two pieces of 1/2-in. electrical tubular metal (EMT) being for enough time to operate from the flooring towards the electrical box for thermostat. Fish the energy lead cable through one duration of conduit. Hot-melt glue the power lead to the groove.Image titled Install Electric radiant-heat Mat Under a Tile Floor Step 4 Fish the thermostat wires through a moment little bit of conduit, after that weave it 12 in. to the mat, maintaining it equidistant from the cable for each side. Nail metal safety dishes throughout the notches into the base dish to protect the wires and cable in which they go through.


Spread the mortar over a 5- to 10-sq.-ft. area of floor. Use the flat region of the trowel to hit the mortar solidly through the mat and into experience of the cement board. You are able to establish an appartment, consistent level by softly floating the trowel over the tops associated with cable, after that utilize the notched part to brush the mortar to create ridges; a 3/8 x 1/4-in. trowel is effective for the majority of tiles. Again, gently skim your trowel on the cable. The sheathing on the cable is difficult, however you nonetheless need certainly to stay away from any “sawing” kind activity or jabs with all the trowel. It will require somewhat learning from mistakes for a flat layer.


Lay the tile, then tap it firmly into destination. Do two resistance tests while setting up the tile to make certain you have gotn’t damaged the cable. (In the event that opposition test fails, begin to see the manufacturer’s guidelines to get the problem.) When the mortar features dried, grout the bones.


Link the power lead and thermostat wire on thermoregulator, after producer's guidelines. Use a programmable thermoregulator so the pad will only think about it as it's needed. It costs even more in the beginning but could save energy and money eventually.
