10 Best Under Tile Heating System 2025 in the United States

The LuxHeat 150 Sqft Mat Kit is an electric radiant floor heating system designed for use under tile, stone, and laminate floors. It uses 120-volt self-adhesive heating mats, providing efficient and even heat distribution across a 150 square foot area. The heating mats are easy to install due to their pre-spaced design and self-adhesive properties, although the heating wires must be embedded in a self-levelling underlayment, thinset, or mortar, which might require professional help for proper installation.

The kit includes a high-quality OJ Microline programmable thermostat with a built-in GFCI (ground fault protection) and a floor sensor, enhancing both safety and ease of use. The thermostat's 7-day program schedule and dual sensing capabilities (air/floor) allow for customized comfort and energy efficiency, though some users might find the programming process slightly complex at first. The system operates at a maximum power of 1800 watts and 15 amps, making it highly efficient.

Another significant benefit is the 25-year limited warranty on the heating mats, providing long-term performance assurance. Additionally, the product's low electromagnetic field (EMF) emissions and safety certifications (UL certified and safe for wet locations) further enhance its reliability. However, the initial cost and the potential need for professional installation could be considered drawbacks. This under-tile heating system is suitable for homeowners looking for a reliable and efficient way to add warmth to their floors, especially in bathrooms, kitchens, or other areas with tile or stone flooring.

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 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.
