10 Best Under Tile Heating System 2026 in the United States

The LuxHeat 100 Sqft Mat Kit is a comprehensive electric radiant floor heating system designed for under tile, stone, and laminate surfaces. Its key features include a 100 square foot self-adhesive heating mat, a cable monitor/alarm, and a user-friendly OJ Microline programmable thermostat with floor sensor and built-in GFCI. The system is designed for ease of installation, with the mat being cuttable and rotatable to fit various floor plans, though care must be taken not to cut the red heater wire. The mat's low-profile heating wires (1/8" in diameter) minimize the impact on the finished floor height, which is a significant advantage for maintaining a seamless floor appearance. Additionally, the product boasts a 25-year limited warranty, reflecting the manufacturer's confidence in its durability and performance.

The thermostat offers advanced features like dual sensing, power logging, a child lock, self-learning capabilities, and a 7-day programmable schedule, which helps manage energy consumption efficiently. However, it is essential to note that the thermostat has a 3-year warranty, which is shorter than the mat's warranty period. The system's energy efficiency is noteworthy, with a power output of 1200 watts and a voltage of 120 volts. The inclusion of Class A GFCI protection enhances safety, making it suitable for wet locations.

On the downside, the initial installation requires careful handling and potentially professional assistance to ensure the heating wires are properly embedded in underlayment or mortar. Despite its complexity, this product is ideal for users seeking a reliable, efficient, and comfortable underfloor heating solution for their indoor spaces.

The LuxHeat 25sqft Electric Radiant Floor Heating System offers a convenient way to add warmth and comfort under tile floors in rooms like bathrooms, kitchens, basements, or living spaces. It uses electric heating cables built into a special uncoupling membrane, which not only heats the floor but also helps prevent tile cracks and protects against moisture – a useful bonus for tile installations. The system delivers 300 watts of heat across 25 square feet, providing efficient and even warmth. Installation requires covering the cables with a leveling compound or thinset, and the membrane adds about 0.26 inches in height, so you’ll want to plan for that in your flooring setup.

Control is a strong point here – the kit includes a programmable touchscreen thermostat with safety features like a ground fault interrupter, dual sensors that measure both air and floor temperature, and a child lock. You can customize heating schedules to save energy and keep costs down. The system is designed for indoor use only and is safe for wet environments, even showers.

It’s backed by a solid warranty: 25 years on the heating system and an impressive 50 years on the membrane, plus responsive customer support, which adds peace of mind if you run into any issues. On the downside, the heater cable cannot be cut or shortened, which means the layout must fit your space as-is. Also, while the system is energy-efficient with programmable controls, running electric floor heating can increase your power bill, so it's best suited for targeted heating rather than whole-house use. If you want a reliable, well-supported under-tile heating solution with easy temperature control and long-term durability, LuxHeat is a strong option to consider.

The LuxHeat 40sqft Electric Radiant Floor Heating System offers a convenient and effective way to add warmth beneath tile, vinyl, or laminate flooring. It uses electric radiant heating with a 240-volt, 480-watt heating cable that covers 40 square feet, delivering a solid heat output of 12 watts per square foot—ideal for maintaining cozy floors in bathrooms, kitchens, or basements. A notable advantage is the inclusion of the Prova Flex-Heat uncoupling membrane, which not only supports the heated floor but also provides waterproofing and crack prevention, enhancing durability over time. Installation height adds about 0.26 inches (6.5 mm), which is relatively low profile and shouldn't significantly affect floor height.

The system comes equipped with a modern Wi-Fi programmable touchscreen thermostat that allows remote control and scheduling via smartphone apps for personalized comfort and energy management. Safety is well addressed through an integrated ground fault circuit interrupter (GFCI) in the thermostat, a key feature to protect against electrical issues. From an energy standpoint, electric heating systems like this can be efficient for targeted room heating, especially with programmable controls to avoid unnecessary use. Warranty coverage is strong, with 25 years on the heating system and 50 years on the membrane, backed by accessible customer support.

It is important to note that the heating cable must not be cut or shortened, which means careful planning of the layout is essential. Also, the system requires the heating wires to be covered with a self-leveler or thinset mortar, so installation may need some skill or professional help. This kit is well-suited for homeowners wanting an easy-to-control, reliable under-tile heating solution with good safety features and long-term warranty, though installation care and layout planning are important to achieve the best results.
