Radiant Floor Heat Keep those toes toasty! From "Bathroom Renovations" episode DBTR-507

Matt and Michelle love their vintage, craftsman-style home – but not the high heating bills and chilly drafts. Amy Matthews helps out with a radiant floor heating system that will keep them and their four kids toasty warm.

Materials:

radiant heating mat
scissors
cement board
cement board screws
screw gun
mesh tape
ohmmeter

Cut through the mesh — but not the red wire — to bring the heating mat around corners.

Installing Radiant Floor Heat

• Cover the subfloor with cement board, attaching to the joists with screws. Tape the seams with mesh tape designed for use with cement board.

• The radiant heating mat is self-adhesive. To install, first decide where and how the unit will receive electric power. Starting at that point, roll out the mat, pressing the sticky side of the mat to the floor.

  Note: The heat is carried through the mat by the thick red wire. Amy checked the mat with an ohmmeter before installation to make sure the circuit was working properly. Be sure not to cut or damage the red wire during installation, or the unit won't work.

• To go past an obstruction – such as the toilet – simply cut through the mesh with scissors and spread the mat apart. Remember, don't cut the red wire.

• To make a turn – or to start a new row – cut through the mesh and extend the mat. The mat doesn't need to cover every inch of the floor; the heat will radiate to the open areas.
