Radiant Floor Heating System for Existing Floors

Electric Floor Heating Systems - Existing Floors

Product Information

QuietWarmth radiant heat film for under subfloors is the perfect solution to add comfort and warmth to any existing flooring, including nail-down wood floors and carpet. Simply place the mats between the subfloor joists and run pre-attached lead wires to an available thermostat. Completely unseen, under subfloor heating panels, warm existing floor surfaces for unparalleled comfort.

Since it is an electric floor heating system, there are no hot water pipes to worry about, thick electrical cables to bury in cement, and most of all no messy installation. Install retro-fit radiant heat to any of your existing floors to add gentle heat for your feet.

The system is incredibly easy to install and can be cut to fit-to-length.
