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 Ditra-Heat Electric Floor Warming Kit is designed primarily for indoor use beneath ceramic or stone tiles. It includes a heating cable that covers 37.5 square feet, paired with an uncoupling membrane to cover a larger area (60.3 sq. ft.). This setup provides radiant heat, which is effective and evenly distributed. The system runs on 120 volts, making it suitable for most standard home electrical setups.

One of its highlights is the programmable touchscreen thermostat, which allows you to set up to six heating periods per day, helping manage comfort and energy use effectively. This can lead to better energy efficiency compared to simpler controls. Installation height is kept minimal since the membrane doubles as uncoupling and heating layers. The product is well-suited for bedrooms, home offices, and living rooms, offering a cozy warmth underfoot.

The kit has a limited coverage area per heating cable—only 37.5 sq. ft.—which means larger rooms may need multiple kits, increasing cost and installation complexity. Also, it is designed mainly for indoor use and tiled floors, so it’s not suitable for carpet or hardwood. This kit is a solid choice for homeowners looking for a straightforward, programmable under-tile heating solution for small to medium-sized rooms, but those needing to cover larger areas should consider the added expense and planning.

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.
