This package contains a 15 sqft electric floor warming mat sized 20″ x 9′ and a TH115-AF-120S digital programmable thermostat with a floor sensor. The mat is UL listed for the US and Canada and rated for wet areas.
Key specifications: 12 W/sqft output at 120V, 1/8″ thickness, and an installation alarm that sounds if the heating wire is damaged during installation. The mat can be flipped and turned for layout flexibility and uses double-sided tape for adherence to the subfloor.
Installation emphasis: The included alarm monitor is intended to prevent damage during cutting and setting; the product is positioned for straightforward retrofit or new construction installs in small areas like bathrooms.
LuxHeat 30sqft Floor Heating Mat Kit
The 30 sqft kit is a larger version of LuxHeat’s mat offerings and includes the UDG4 programmable thermostat with an integrated GFCI, a cable monitor/alarm, and a floor sensor. Suitable for under tile and laminate flooring.
Design and installation: The mat uses the same 3″ wire spacing and self-adhesive mesh approach, allowing turns and layouts for irregular shapes. The product reiterates the requirement that heater wires be fully embedded in a self-leveling compound or thinset for safe performance.

Warranty and support: Like other LuxHeat kits, this product emphasizes manufacturer experience and warranty coverage to address long-term reliability and service needs for residential installations.
30 sqft Electric Floor Heating Mat Kit, HeatTech
This 30 sqft mat kit includes an AUBE TH115-AF-120S digital 7-day programmable thermostat with floor sensor. The heating cable is 1/8″ thick, with an armored cold lead about 10 ft long, and the mat is advertised as having zero EMF.
Performance data: Specified at 12 W/sqft (360 W total), 120V operation, and a 3″ spacing of heating cable. The adhesive-backed mat is engineered to lay flat without staples and can be cut at the mesh to make turns during installation.
Application notes: The kit targets tile, stone, marble, laminate, vinyl, and wood floors where a thin-profile electric system is desired. The listed thermostat supports 7-day programming for scheduled operation and energy management.
LuxHeat 45sqft Electric Radiant Floor System
This kit uses a loose heating cable combined with a manual Prova Flex-Heat uncoupling membrane, offering a 3-in-1 underlayment solution for heating, waterproofing, and crack control. The system includes a touchscreen UDG4 thermostat with GFCI, alarm, and a floor sensor.
System advantages: The membrane supports tile installations by decoupling substrate movement and providing waterproofing, while the cable layout enables custom configurations in complex floor plans. The thermostat lists advanced features including dual sensing (air/floor), power logging, child lock, and programmable schedules.
Installation guidance: Heating wires must be covered with a self-leveling compound or thinset. The uncoupling membrane may require additional thinset or mortar work and is intended for use where waterproofing and crack isolation are priorities.
Buying Guide: How To Choose The Right Radiant Floor Heating Kit
Selecting a radiant floor heating kit requires balancing room size, floor covering, installation method, and electrical capacity. The sections below outline the primary factors to compare.
System Type And Coverage
- Pre-Spaced Mats — Best For Regular Areas: Mats with fixed cable spacing are faster to install in rectangular or moderately shaped zones. They are common for bathrooms and small rooms.
- Loose Cable With Membrane — Best For Complex Layouts: Cable plus uncoupling membrane allows custom runs around fixtures and irregular shapes and adds waterproofing and crack isolation for tile installations.
- Square Footage Match — Choose a kit that closely matches your heated area. Avoid overlapping or excessive trimming of heating wires; mesh can be cut but wires cannot.
Thermostat Features And Safety
- Floor Sensor — Essential For Stable Surface Temperatures: Dual sensing (air + floor) or floor-sensing-only thermostats provide accurate control for tile and stone floors.
- Built-In GFCI — Non-Negotiable For Wet Areas: Integrated GFCI in the thermostat or separate GFCI protection reduces electrical shock risk and may be required by code in bathrooms.
- Programmability & Wi-Fi — Schedule Heating For Efficiency: 7-day or multi-event programs and Wi-Fi connectivity reduce runtime and can lower operating costs.
Installation Considerations
- Floor Type Compatibility — Verify manufacturer guidance for tile, laminate, engineered wood, or vinyl. Some kits specify underlayment or thinset requirements.
- Embedding The Cable — Most products require the heating wires to be embedded in a self-leveling compound or thinset to protect the wires and transfer heat effectively.
- Installation Monitor/Alarm — A cable monitor that detects damage during installation helps prevent failures and is recommended for DIY projects.
- Professional Electrical Connections — Final connection to household wiring usually requires a licensed electrician to comply with electrical code and ensure proper GFCI function.
Performance And Power
- Watts Per Square Foot — Common outputs are around 10–12 W/sqft for supplemental heating. Higher outputs produce faster warm-up but require more electrical capacity.
- Room Heat Load — Consider insulation, ceiling height, and window area. In well-insulated rooms, lower wattage may be sufficient; in poorly insulated areas, consider higher output or additional heating sources.
- Electrical Circuit Capacity — Check that your panel and circuit can support the kit’s amperage. Kits typically specify voltage and amp draw (e.g., 120V, 1.5–3.0 A for smaller mats).
Durability, Warranty, And Support
- Manufacturer Warranty — Compare warranty lengths and coverage for both mat/cable and thermostat components.
- Customer Support And Documentation — Look for clear installation instructions, wiring diagrams, and accessible technical support.
- Third-Party Listings — UL/cUL or CSA listings indicate that the components meet recognized safety standards for North American use.
Comparison Perspectives
- Small Bathroom Retrofit — Pre-spaced mats sized to the area with an integrated thermostat and GFCI are efficient and straightforward.
- Large Or Irregular Room — Loose cable with an uncoupling membrane offers layout flexibility and added waterproofing for tile installations.
- Energy Management — Programmable thermostats and scheduling allow targeted runtime, reducing energy use compared to continuous heating.
- DIY vs Pro Installation — Mats are often more DIY-friendly; membrane and loose cable installations may require more advanced tiling skills and professional electrical work.
When evaluating kits, focus on matching the system type to your floor material and room layout, ensuring required safety features like floor sensors and GFCI protection, and confirming electrical compatibility with your home. Proper embedding of cables and following manufacturer instructions are key to long-term performance and safety.
