Danfoss TX-FH Electric Floor Heating System Danfoss TX-FH Electric Floor Heating System Danfoss TX-FH cables are a thick floor heating solution. Thick cables have a larger diameter than the Danfoss LX floor heating cables, allowing them to be lower in COST, higher in HEAT OUTPUT, and more DURABLE. They are installed in mud beds below the flooring materials and are most often used in new construction where overall material cost is a primary concern.

This is the area you would walk upon. Do not install heating cable under the permanent fixtures. Select the cable spacing. Never space cables closer than 4” apart . Danfoss recommends 6” standard spacing. You should also plan the location of the thermostats, floor sensors locations and their conduit’s location.
