10 Best Under Tile Heating System 2026 in the United States

The SunTouch TapeMat Electric Under Floor Heating Kit is designed for easy installation under various types of flooring such as tile, stone, wood, or laminate. This flexibility makes it a versatile choice for both residential and commercial applications. It offers a decent heat output with its 420-watt power, suitable for heating a 35 square foot area effectively, making it a good fit for smaller spaces like bathrooms or kitchens.

One of the kit's standout features is its user-friendly installation process. The mat can be easily rolled out and adjusted to fit awkward spaces by cutting the mesh and placing the blue wire as needed. The inclusion of a programmable touchscreen thermostat adds convenience, allowing for precise temperature control and the implementation of auto-scheduling, which can enhance energy efficiency if used effectively.

The mat's installation height is relatively thin at 1/8 inch, which minimizes the impact on floor height but may require careful handling during installation. The included LoudMouth installation monitor is a thoughtful addition, providing a safety check and peace of mind with its alarm system during the installation process. In terms of energy efficiency, the system relies on a 120-volt power source, which is standard but might not be the most efficient compared to some alternative systems available. This heating kit is best suited for users seeking a reliable and straightforward underfloor heating solution with moderate heating needs.

The LuxHeat 200sqft Floor Heating Cable Kit offers a comprehensive solution for under-tile heating needs. One of its notable strengths is the ease of installation, making it accessible even for those without extensive technical skills. The kit includes everything you need: a heating cable, a programmable touchscreen thermostat, a floor sensor, strapping, and an alarm, which is particularly useful for ensuring a smooth installation process. The thermostat is user-friendly and comes with various features like dual sensing, power logging, child lock, and a 7-day program schedule that helps in managing energy costs efficiently.

Additionally, the heating system allows for individual room control, enhancing personal comfort. The design flexibility of the loose-lay heating cables makes it suitable for various flooring types, including tiles and laminate. However, it is crucial to note that the heating cables must be properly embedded in a self-leveling underlayment, thinset, or mortar and should not be cut or shortened. Energy efficiency is another strong point, with the system offering ultra-low electromagnetic fields and UL certification for safety. The 25-year limited warranty is a significant assurance of the product's longevity and performance.

On the downside, the initial cost and the requirement for a 240-volt power source might be a consideration for some users. Additionally, while the thermostat has a 3-year warranty, some might find it relatively short compared to the 25-year warranty of the heating cables. In summary, this heating kit is well-suited for those seeking a reliable, customizable, and energy-efficient under-tile heating solution, especially in residential settings.

The LuxHeat 60sqft Floor Heating Mat Kit offers a luxurious and comfortable heating solution for under-tile installations, as well as laminate and vinyl floors. Key features include a 120-volt self-adhesive heating mat and the OJ Microline UDG-4999 programmable thermostat with ground fault protection (GFCI). The mat's design promotes easy installation, as it can be cut, flipped, or rotated to fit various floor layouts, though it's essential to embed the heating wires properly in a self-leveling underlayment or mortar for safe use.

One strength of this system is its high heat output of 720 watts, providing ample warmth for most indoor spaces. The minimal installation height of the 1/8-inch diameter heating wires ensures a negligible impact on the finished floor level. The programmable thermostat offers advanced features like dual sensing (air and floor), power logging, and a 7-day program schedule, which helps reduce operating costs and enhance comfort. The unit is energy-efficient and includes a built-in GFCI for safety.

LuxHeat's 25-year limited warranty on the heating mat and 3-year warranty on the thermostat provide added peace of mind. However, users should be aware that the system requires careful installation, particularly regarding the handling of the red heater wire, which must not be cut or shortened. Despite this, the LuxHeat team's experience and commitment to customer service make this product a reliable choice for those seeking an efficient and user-friendly under-tile heating solution.
