LuxHeat 20sqft Floor Heating Mat Kit
This kit Includes a 20 sqft 120V self-adhesive heating mat, a cable monitor/alarm, and an OJ Microline UDG-4999 programmable thermostat with floor sensor and built-in GFCI. The mat features 3″ pre-spaced heating wires on an adhesive mesh that can be flipped, cut around (mesh only), or rotated to fit room shapes. Installation requires embedding the heater wires in self-leveling underlayment, thinset or mortar. The manufacturer provides a 25-year limited warranty and claims 50 years of industry experience. This kit is presented for use under tile and laminate flooring where a 20 sqft coverage is appropriate.
Warming Systems 15 Sqft Heating Mat
The Warming Systems kit contains a 15 sqft electric floor warming mat sized 20″ x 9′ and a digital programmable thermostat TH115-AF-120S with a floor sensor. It includes an installation warning monitor that sounds an alarm if the cable is damaged during installation. Mat specifications show 12 W/sqft output, UL listing for USA and Canada, 1/8″ thickness, and safe for wet areas. The mat is designed to be flipped and turned to fit complex layouts and uses double-sided tape on the mesh for adhesion to subfloors.
LuxHeat 50sqft Radiant Floor Kit
This 50 sqft kit is a larger-coverage option and includes a self-adhesive heating mat, cable monitor/alarm, and an OJ Microline UWG4-4999 WiFi programmable thermostat with floor sensor and built-in GFCI. It retains the same 3″ pre-spaced heating wire mesh that can be flipped, cut in the mesh, or rotated to conform to a layout. The thermostat supports WiFi connectivity for remote control and includes features typical of the UDG4 series. Installation guidance specifies embedding the heating wires in thinset or self-leveling underlayment.
30 sqft Electric Floor Heating Mat Kit
This HeatTech 30 sqft kit ships with an adhesive-backed heating mat sized 20″ wide x 18.3′ long, a 10 ft cold lead, and an Aube TH115-AF-120S 7-day programmable thermostat with floor sensor. The cable spacing is 3″ and the system outputs 12 W/sqft (approx. 41 BTU/sqft). The mat is 1/8″ thick, laid flat without stapling, and the manufacturer notes zero EMF. Installation follows common practice: heating cable must be embedded in appropriate mortar or leveling compound and connected to the supplied thermostat and sensor.
LuxHeat 45sqft Radiant System With Membrane
The 45 sqft LuxHeat kit includes a heating cable sized for 45 sqft, a 60 sqft Prova Flex-Heat uncoupling membrane for waterproofing and crack prevention, a touchscreen programmable thermostat (UDG4-4999) with integrated Class A GFCI, an alarm, floor sensor, and a wood float for membrane installation. The uncoupling membrane offers 3-in-1 benefits: heated floor support, waterproofing, and crack isolation, which is useful beneath tile installations. As with similar systems, heater wires must be covered with thinset or a self-leveler and must not be cut.
Buying Guide: How To Choose A Radiant Floor Heating System
Selecting the right radiant floor heater depends on coverage area, floor type, thermostat control, and installation constraints. This guide breaks down the most important considerations and compares perspectives to help identify the best fit.
Coverage And Sizing
- Measure Usable Floor Area: Exclude cabinets, fixtures, and other non-heated zones. Choose a mat/cable size that matches or slightly under-sizes the usable area.
- Multiple Mats vs Single Mat: For irregular rooms, multiple smaller mats or loose cable on an uncoupling membrane can provide better fit than one large mat.
Thermostat Features And Control
- Floor Sensor Required: Floor-sensing thermostats measure surface temperature and prevent overheating—important for tiles and laminate.
- Programmable Schedules: 7-day or multi-event programming improves energy efficiency by heating only when needed.
- WiFi Or Remote Access: WiFi thermostats allow remote scheduling and energy monitoring; useful for vacation homes or centralized control.
Safety And Electrical Considerations
- Built-In GFCI: Thermostats with integrated Class A GFCI provide ground-fault protection without requiring a separate GFCI breaker in some installations.
- Installation Monitor: An installation alarm that detects cable damage during installation reduces risk of post-install failures.
- UL/cETL Listings: Choose systems with recognized safety listings for U.S./Canadian code compliance.
Flooring Compatibility And Installation
- Tile & Stone: Direct thinset embedding or using uncoupling membranes is common; membranes can provide waterproofing and crack isolation.
- Laminate, Vinyl, Wood: Verify manufacturer approval; many mats are suitable under specific engineered or vinyl planks but check maximum floor temperatures.
- Embedment Requirements: Heating wires must be embedded in mortar or leveling compound according to product instructions to ensure even heat transfer and protect cables.
Output And Performance Metrics
- Watts Per Square Foot: Typical electric systems range from about 10–20 W/sqft. Lower values suit supplemental warmth; higher values suit primary heat in colder spaces.
- Response Time: Electric radiant has moderate thermal inertia; tile retains heat longer. Expect slower ramp-up compared to forced-air but stable, even surface temperatures.
Installation Flexibility And Accessories
- Cuttable Mesh vs Loose Cable: Mesh mats simplify installation in rectangular areas. Loose cable with membrane allows more custom layouts and odd-shaped rooms.
- Uncoupling Membrane: Useful when installing tile over substrates prone to movement or moisture. It also allows creative tile layouts and integrated waterproofing.
- Cold Lead Length: Check cold lead length to ensure the thermostat location is reachable without splicing in-conduit.
Warranty, Support, And Longevity
- Warranty Terms: Compare limited warranties and what they cover—some manufacturers offer multi-decade coverage on cable and components.
- Technical Support: Manufacturer installation guidance, available customer service, and compatibility documentation reduce installation risk.
Comparison Perspectives
- Small Bathroom Install: 15–20 sqft mats (Warming Systems 15, LuxHeat 20, BLARALA 20) are optimized for individual baths and limited layouts.
- Larger Room Or Whole-Room Heat: 30–50 sqft kits (HeatTech 30, LuxHeat 45/50) cover larger footprints and may include membranes or WiFi thermostats for central control.
- Budget vs Feature Set: Basic mat kits with a programmable thermostat are cost-effective for simple projects; WiFi thermostats and membranes add flexibility and convenience but increase system complexity.
Final installation tips: Always follow manufacturer instructions, test the cable with the included megohmmeter or monitor before embedding, install the floor sensor exactly where recommended, and confirm local electrical code requirements for dedicated circuits and GFCI protection.
