10 Best Underfloor Heating Mats 2025 in the United States

The LuxHeat 20 Sqft Mat Kit is designed for those looking to add electric radiant floor heating under tile, stone, or laminate flooring. One of its main strengths is the self-adhesive heating mat, which simplifies installation and ensures the mat stays flat. This kit also includes a high-quality, user-friendly OJ Microline UDG4-4999 programmable thermostat with a built-in GFCI and floor sensor, adding safety and convenience with its 7-day program schedule and various advanced features like child lock and power logging.

Additionally, the dual wire technology minimizes EMF levels, which is a plus for health-conscious users, and the mat’s 25-year limited warranty speaks to its durability and the company's confidence in their product. However, the heating mat cannot be cut or shortened, limiting flexibility in some layouts. Furthermore, the requirement to embed heating wires in a self-leveling underlayment, thinset, or mortar might add to the installation complexity for some DIY enthusiasts.

With a heating output of 12 watts per square foot, this mat is efficient for most residential applications. Potential buyers might want to consider their specific installation needs and whether the lack of cutting flexibility could be a limitation in their project.

The SunTouch ConnectPlus WarmWire Under Floor Heating Kit is a versatile option for those looking to add radiant heat to their floors. With a heating output designed to cover 20 square feet at 120 volts, it is suitable for small to medium-sized areas. The kit includes a comprehensive set of components: a heating wire, a floor sensor, and a Wi-Fi-enabled thermostat for remote control via a mobile app. This makes it convenient for users who want to maintain optimal temperature settings from anywhere.

Installation is straightforward over plywood, backer board, or concrete slabs, offering flexibility across various flooring types, including tile, stone, wood, and laminate. However, the heating wire cannot be cut, which might pose challenges in spaces with unique layouts. The included SunStat ConnectPlus thermostat stands out with features like touchscreen controls, voice activation via Alexa or Google, and energy usage monitoring. Some users might find the setup complex if they're not familiar with smart devices.

The product enjoys positive feedback, reflected in its strong customer ratings, although it ranks lower in popularity within its category. At 5.59 pounds, it is lightweight and portable, making handling easier during installation. It's ideal for someone looking for a sophisticated, yet easy-to-install underfloor heating system, but might not suit those with very large or irregularly shaped spaces.
