LuxHeat 20sqft Floor Heating Mat Kit

LuxHeat 20sqft Floor Heating Mat Kit

Check Price on Amazon

This kit includes a 20 sq ft self-adhesive heating mat, a cable monitor/alarm, and an OJ Microline UDG-4999 programmable thermostat with integrated GFCI and floor sensor. It is designed for installation under tile, laminate, and similar finishes.

Key installation notes: the mat is 3″ pre-spaced and can be cut, turned, or flipped to cover irregular areas, but the red heating wire must not be cut or shortened. Wires must be embedded in a self-leveling underlayment, thinset, or mortar for safety and performance.

Warranty and support are highlighted by LuxHeat’s long industry experience and a 25-year limited warranty. The kit is positioned for compact rooms or zones where a complete in-floor heating system is required with built-in ground fault protection.

The 35 sq ft kit contains a self-adhesive heating mat, alarm cable monitor, and the UWG4 WiFi programmable thermostat with built-in GFCI and floor sensor. It targets larger rooms or multi-zone applications where remote control is desired.

Installation follows the same safety guidance: 3” spacing, do not cut heating wires, and embed cables in appropriate underlayment or thinset. The mat’s adhesive mesh and double-sided tape help the mat remain flat during tiling or laminate installation.

WiFi thermostat features allow scheduling and remote adjustments via app, which is useful for pre-warming floors before occupancy. The kit emphasizes convenience and centralized control for larger heated floor areas.

All-In-One Electric Radiant Floor Heating Kit 51 Sq Ft

GTDsupply 51 Sq Ft Radiant Floor Heating Kit

This kit is built around loose heating cable compatible with Schluter’s DITRA-HEAT membrane and includes the DHERT102/BW touchscreen programmable thermostat. The thermostat supports both 120V and 240V systems and up to six programmable cycles.

Two floor temperature sensors are supplied, which can be installed alongside the heating cable. The kit is positioned for installations where a membrane approach or uncoupling layer like DITRA-HEAT is preferred for waterproofing and tile movement management.

Because the system is membrane-compatible, it’s suited for professional tile installations or renovations that require an integrated membrane solution. The thermostat’s touchscreen interface and multi-cycle programming support repeated heating schedules for comfort management.

VEVOR Floor Heating Mat, 30 Sq.ft Kit

VEVOR 30 Sq.ft Floor Heating Mat

Check Price on Amazon

VEVOR’s 30 sq ft mat kit includes the heating mat, a touchscreen thermostat with built-in GFCI, an installation alarm, and a floor temperature sensor. The mat has 2″ spacing and an adhesive backing for straightforward placement on the subfloor.

The thermostat supports dual sensing (air and floor), power logging, child lock, and a 7-day scheduling mode with multiple control modes. The mat is thin (about 1/8 inch) and requires embedding in an underlayment or thinset to protect wiring and ensure effective heat transfer.

VEVOR highlights uniform bottom-up heating and multiple thermostat modes for occupant comfort. As with other kits, the heating cable must not be cut and must be fully embedded in the chosen leveling compound for safe operation.

Mysa Smart Thermostat For Electric In-Floor Heating

Mysa Smart Thermostat For Electric In-Floor Heating

Check Price on Amazon

Mysa is a high-voltage smart thermostat designed for electric in-floor heating systems operating on 120–240V. It includes a Class A GFCI and provides app-based control, voice assistant integration (Alexa, Google, Siri), and scheduling without subscription fees.

This unit is intended to replace a standard touchscreen thermostat and add smart features like remote control, energy usage history, and integration into home automation setups. It does not work with hydronic (water-based) systems.

Mysa offers a modern control interface and compatibility with a wide range of electric floor systems. Its built-in GFCI simplifies wiring in some setups, but installers should verify compatibility with the specific heating cable or mat being used.

Buying Guide: How To Choose An In-Floor Electric Heater

Selecting the right in-floor electric heating system requires matching the kit to room size, floor covering, electrical supply, and control preferences. The sections below cover key purchase considerations.

Tips for Getting the Best HVAC Prices

  1. Prioritize Quality Over Cost
    The most critical factor in any HVAC project is the quality of the installation. Don’t compromise on contractor expertise just to save money.
  2. Check for Rebates
    Always research current rebates and incentives — they can significantly reduce your overall cost.
  3. Compare Multiple Quotes
    Request at least three estimates before making your choice. You can click here to get three free quotes from local professionals. These quotes include available rebates and tax credits and automatically exclude unqualified contractors.
  4. Negotiate Smartly
    Once you've chosen a contractor, use the proven strategies from our guide — How Homeowners Can Negotiate with HVAC Dealers — to get the best possible final price.

1. Kit Type: Mat Vs. Loose Cable

  • Heating Mat: Pre-spaced mats are faster to install for regular layouts and tile or laminate. They simplify layout planning in rectangular rooms.
  • Loose Cable: Offers maximum flexibility for irregular shapes, around fixtures, or when using an uncoupling membrane like Schluter DITRA-HEAT.

2. Thermostat And Control Features

  • Programmable Thermostats allow schedules to reduce energy use and preheat floors before occupants arrive.
  • WiFi/Smart Thermostats (like Mysa or WiFi-enabled kits) offer remote control, voice integration, and energy tracking.
  • Built-In GFCI provides integrated ground-fault protection and can simplify wiring in some installations.

3. Electrical Requirements

  • Verify supply voltage compatibility (120V vs 240V) and circuit breaker capacity. Some thermostats support both voltages, others are voltage-specific.
  • Confirm that the chosen kit’s wattage per square foot matches your electrical panel and wiring capabilities.

4. Installation Method And Subfloor

  • Heating wires must be embedded in self-leveling underlayment, thinset, or mortar to ensure heat transfer and protect wiring.
  • Membrane-compatible kits are preferable for wet areas or where tile movement control is needed.
  • Adhesive-backed mats versus loose cables influence labor time and tile flatness during installation.

5. Room Size And Layout

  • Choose a kit that closely matches usable heated square footage; mats come in fixed sizes while cable kits can be configured to fit.
  • Consider leaving areas under permanent fixtures (cabinets, tubs) unheated unless recommended by manufacturer.

6. Safety And Code Compliance

  • Look for integrated GFCI protection and follow local electrical code for dedicated circuits and breaker sizing.
  • Use an installation alarm or cable monitor during installation to detect damage before covering with tile or underlayment.

7. Warranty And Manufacturer Support

  • Longer limited warranties indicate manufacturer confidence. Confirm warranty terms for mats, cables, and thermostats.
  • Manufacturer support can be important for layout advice, troubleshooting, and replacement parts.

8. Performance Metrics

  • Check wattage per square foot to estimate heat output and warm-up time. Higher wattage may be required in colder subfloor conditions.
  • Dual sensors (floor and air) provide more stable temperature control and prevent overheating of flooring materials.

9. Compatibility With Flooring Materials

  • Most electric floor heating kits are suitable for tile and some laminate. Verify with the kit manufacturer for specific flooring limitations.
  • Thicker underlayment or certain adhesives can affect heat transfer; follow manufacturer installation instructions to ensure optimal performance.

10. Budget Considerations

  • Balance the cost of the kit, thermostat, and installation labor. Mat kits reduce install time while loose cable systems may require more layout work but offer flexibility.
  • Smart thermostats may add upfront cost but can improve long-term energy management through scheduling and remote control.
