About This Product

A gentle electric radiant heat system designed specifically for dry installation under floating wood and laminate floors. This 2-in-1 system allows you to cut mat in middle and use both ends of mat. Helping reduce waste with money savings. A low profile, line voltage system, it features gradual warmth from low wattage resistance heating of ultra-thin, flexible radiant heat film. Installed easily over a subfloor or over an acoustic/insulating underlayment as part of the overall floor assembly, it uses just 12-Watt per sq. ft. to gently raise the temperature of the floor, conforming to the warranty requirements of many floating floors. The system, which sports an impressive 99% efficiency, includes temperature limiting properties so the film does not overheat. Its available in 4 convenient rollout mat sizes that will accommodate most any layout. Each mat has wires pre-attached for ease of installation.

Questions & Answers

Q:If multiple mats are used can they all be linked to one wireless thermostat?
by|Nov 25, 2023
1 Answer
Answer This Question

A:  There is no way to wirelessly link them. Everything has to be wired in parallel to the thermostat. You are able to control up to 150sf of mats per thermostat on the 120V system and up to 300sf on the 240V system.

      Q:My existing floor is 3/8" thick and looks like DRICORE OSB or cork floor. It also has quietwalk underlayment underneath. If I want to install QuietWarmth on top of my floor, do I still need to install another underlayment before installing QuietWarmth?
      by|Sep 12, 2023
      1 Answer
      Answer This Question

      A:  When installing QuietWarmth over a wood substrate, an underlayment is recommended but not required. The underlayment will help with insulation value and help with embedding the lead wires. But again, it is not a requirement of the QuietWarmth system.
