Radiant Floor Heating Frequently Asked Questions

Purchasing Questions

    Contact us at 1-866-714-3997 or click here
  2. Where can I install radiant heat mats?
    Nuheat may be installed under any ceramic tile, marble, or natural stone floor application, as well as laminate and engineered flooring.
  3. How much do mats cost to operate?
    In a typical bathroom, a radiant heat mat costs as little as the bathroom lighting. Energy consumption can be further minimized with a programmable thermostat. At full power, the mat uses only 12 watts per square foot to heat the floor to a temperature of 85-90F.
  4. What kind of warranty does Nuheat provide?
    Nuheat radiant floor heating mats and cable are UL approved and provide a 25-year warranty from date of purchase, when installed under tile, stone, laminate, and engineered wood floors.

Usage Questions

  1. Can radiant floor heating mats be used as a primary heat source?
    Nuheat is not sold as a primary heat source. However, homeowners often find they require no supplemental heat in a room after Nuheat has been installed.
  2. Can I use Nuheat cable or mats in my shower, on my shower bench, in my sauna, or other areas where the floor gets wet? Yes, Nuheat cable and mats are both warranted for use in wet applications and are an affordable luxury.

Installation Questions

  1. How is the mat installed?
    The tile setter simply installs the radiant heat mat with acrylic modified thinset directly over the  prepared sub-floor and under the finished flooring material.
  2. How much height does the Nuheat mat add to the floor?
    The Nuheat mat is 1/8” thick and, with thinset, will add between 3/16” and 1/4” inch to the floor height.
  3. How is the mat turned on and off?
    There are a number of options for controlling your floor-warming system. We recommend one of our Programmable Floor-Sensing Thermostats as they are Energy-Star Certified and operationally efficient.
  4. What is the mat fabric made of?
    The mat fabric is made of highly durable polyester material. It is strong, porous and extremely lightweight.
  5. What kind of thinset do I use?
    We recommend using polymer-modified thinset or acrylic-modified thinset. The additives give the thinset more adhesion to strongly bond the mat to the sub-floor.
  6. What kind of trowel should be used to install Nuheat?
    Radiant Way recommends a 1/4”x1/4” square notched trowel for bonding the mat to the sub-floor.
  7. Can I control more than one radiant heat mat on a single thermostat?
    Yes.  Mats can be used together with their individual leads joined at the  thermostat or an alternative junction box. The thermostat is rated at 15 amps in both 120V and 240V.
  8. What size box does the thermostat fit into?
    All our thermostats, with the exception of the Harmony, fit into a separate single gang box. Where possible, use a four square box with a single gang mud-ring to simplify the final hook-up.  The Harmony requires a double-gang box.
  9. How do I extend the leads?
    Nuheat manufactures all mats with a standard 10 foot lead. Customers can request extended leads up to 22 feet. Beyond 22 feet, the electrician can extend the leads by using a junction box utilizing romex or wire.
  10. What advantage does 240V have over 120V?
    If using Nuheat for a room over 140 square feet we recommend 240V. If using Nuheat for a room over 300 square feet, a relay allows the homeowner to use only one thermostat.
  11. What is a relay?
    A relay allows the homeowner to use one thermostat for an area over 300 square feet.
  12. If my installer damages the radiant heat mat, what happens next?
    If your MatSense Pro sounds an alarm, your mat or cable may have been damaged during the installation process.  Do not install flooring over the damaged mat.  Contact your electrician or tile-setter to trouble-shoot the problem.  We  can assist you in the purchase of a floor heating repair kit.
  13. What is EasyMat and why would I need it for my Nuheat job?
    EasyMat is an underlay for superior heat retention and also acts as an anti-fracture membrane.  If you plan to use Nuheat on concrete, EasyMat will allow your floor to warm up faster and retain heat longer. An anti-fracture membrane like Easymat is essential if you’re using tile on a uneven surface – it creates a bonded crack prevention system for sub-floor movement up to ¼”.
