underlayments e.g. TCNA Methods RH 116A 140 can also be used to encapsulate electric floor warming systems when the substrate requires attention. Finish off the tile installa- tion with an appropriate ANSI 118.6 or better cement-based grout or an ANSI A118.13-compliant epoxy- based grout for even better perfor- mance and ease of maintenance. Cautions with electric ooring-warming installations Cure time Allow at least a 3-to-7 day cure period after the final grouting period before activat- ing the floor-warming system. This will allow all of the installation components adequate time to cure out and reach sufficient strength. If there is any doubt on this matter consult with the electric heat and tile installation materials manufacturer for their guidance. Typically the cure-period question arises during installations that require quick return to service times e.g. bathroom or kitchen remodeling. Expansion joints Since the heating and cooling of floors occurs at more frequent intervals with heat- ed floors the inclusion of movement joints is mandatory. In fact in many cases placing the movement joints in accord with the exterior recom- mendations of TCNA EJ171 is a good idea. Troubleshooting In addition to manufacturer-specific instruc- tions on troubleshooting electric radiant heat system the National Tile Contractors Association NTCA includes a troubleshooting section in its NTCA Reference Manual on this topic that can be consulted for common issues that might occur. The chapter is titled Radiant Heat Issues for Tile Stone Installations located on pages 159-160 of the 20152016 manual. As is the case with many sections in the publica- tion valuable and practical guid- ance is provided to assist installers with these applications. It is important to the end user to select an electric floor warming sys- tem with comprehensive warranty coverage that includes both labor and materials. Electric floor warming both in mat type or loose wire configuration is a cost-effective warming solution upgrade that creates a comfortable environment Keeping your custom- ers warm and content results in positive feedback great referrals and ultimately repeat business.
