Profile: First Trace Heating Direct Ltd. supplies electric underfloor heating systems and electric trace heating for pipework, tanks & fittings. Our trace heating systems are the ideal solution for maintaining the temperature of pipework, tanks and fittings. We provide ThermMAT, which is a heating mat with a twin-wire heating element that is pre-mounted onto a self-adhesive, commercial grade fiberglass mesh. This holds the heating cable in place, maintains optimum spacing between rows of cable and makes the installation process both quick & simple.
