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 20sqft Electric Radiant Floor Heating System offers a comprehensive solution for under-tile heating needs, making it a strong contender in its category. Starting with the heating type, it uses electric heating cables that are both efficient and effective. The heat output is substantial, providing 12 watts per square foot, ensuring ample warmth for comfortable living spaces. The 120-volt system is designed to cover 20 square feet, which is suitable for small to medium-sized rooms like bathrooms or kitchens.

One of its standout features is the Prova Flex-Heat uncoupling membrane, which not only aids in even heat distribution but also provides crack prevention, waterproofing, and load support capabilities. This adds a layer of durability and flexibility to the flooring, making it a versatile choice for different areas in the home. The installation height of 0.26 inches is relatively low, which is advantageous for maintaining the floor height and avoiding noticeable transitions between heated and non-heated areas.

Control options include a programmable touchscreen thermostat (UDG4-4999) that is user-friendly and modern, offering features like dual sensing, power logging, and a 7-day programmable schedule. This allows for tailored and efficient heating schedules to optimize energy usage. Additionally, safety is a priority with the included ground fault protection. Energy efficiency is further enhanced by the self-learning feature of the thermostat, which adapts to the user’s habits to reduce energy waste. The system includes a comprehensive warranty—25 years for the LuxHeat cable and 50 years for the Prova membrane—providing long-term peace of mind. Customer support is readily available, which is beneficial for troubleshooting any issues. On the downside, the system requires careful installation, particularly ensuring the heating wires are adequately covered, which might be challenging for DIY enthusiasts.

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.
