          Installed under Engineered floor Nov. 2019, this product worked for the first few months and has now seemingly reduced its preformance. Tested the controller and that is not the issue. I have not tested the resistance of the floor wiring.

            Easy way to provide extra heating to a room.
            I installed this heating underlayment mat under an engineered hardwood floor. It was eay to install and worked beautifully. My daughter's room tends to be cooler than other rooms in our household so I used the heated underlayment as a supplement. No more space heaters needed anymore!

            radiant floor mat
            This particular floor mat is made by NU-Heat and is an exceptional product and easy to work with. I have used it in high end bath remodels under ceramic tile and the thermostats that are offered to work with this product are pricey but worth the money and are simple to use, attractive and user friendly. You will want an electrician to install the feed wires for the thermostat but the rest you can do yourself.
