The right electric radiant floor heating kit depends on the area you plan to heat, the flooring installation, and the controls included. For a small project, consider the 15-square-foot cable kit or a compact LuxHeat mat. The 30- and 40-square-foot systems suit mid-sized areas, while the 150-square-foot kit is designed for broader coverage. Product listings do not provide current prices here, so compare the included components and coverage before checking the latest cost.
| Product | Listed Coverage | Best For |
|---|---|---|
| LuxHeat 40 Sq Ft System | 40 sq ft | Tile projects needing a membrane |
| Electric Cable Kit | 15 sq ft | Small heated-tile areas |
| LuxHeat 30 Sq Ft System | 30 sq ft | Mid-sized projects with a touch thermostat |
| LuxHeat 150 Sq Ft System | 150 sq ft | Larger areas and Wi-Fi controls |
| LuxHeat 20 Sq Ft Mat | 20 sq ft | Small mat installations with GFCI protection |
LuxHeat 40 Sq Ft System With Membrane

Best for: A medium-sized tile installation where an uncoupling membrane and programmable controls are useful. This 120-volt kit lists 40 square feet of coverage and includes heat cable, a UDG4 programmable thermostat with GFCI, a sensor, and an alarm.
The membrane is a distinguishing inclusion compared with simpler cable-only kits. Choose this system if you want the heating components and under-tile membrane together. Its listed coverage is limited to 40 square feet, so it may not suit a larger project without a separate plan for additional coverage. Confirm installation and electrical requirements before purchase.
15 Sq Ft Electric Radiant Floor Cable Kit

Best for: Small tile areas that need a cable-based system with programmable control. The listing specifies 15 square feet, 120 volts, a UWG5 thermostat, a sensor, and an installation monitor. It also lists a 25-year warranty and says the product is made in the USA.
Compared with the 20-square-foot mat below, this kit offers five fewer square feet of stated coverage. It is a suitable option when the planned heated area is compact and the listed cable-kit components match the project. Avoid choosing it based on room size alone; measure the actual area intended for heating.
LuxHeat 30 Sq Ft System With Touch Thermostat

Best for: A mid-sized floor area when a touch programmable thermostat is a priority. The product name specifies 30 square feet and 120 volts. That coverage places it between the 15-square-foot cable kit and the 40-square-foot system in this selection.
Choose this option if the listed area and thermostat style fit your project. The supplied product information does not specify all included components or flooring types, so check the current listing for those details before ordering. Its 30-square-foot coverage may be insufficient for a larger installation.
LuxHeat 150 Sq Ft System With Wi-Fi Thermostat

Best for: A larger tile project where broader listed coverage and Wi-Fi programmable control are desired. This 120-volt system includes a UWG5 Wi-Fi thermostat with GFCI, uncoupling membrane, heater cable, sensor, and alarm.
Its 150-square-foot coverage is substantially greater than the other options in this comparison. Choose it when the planned heated area is large enough to justify that coverage and the listed kit components fit the installation. The supplied details focus on tile use; confirm flooring suitability and electrical requirements for your specific project.
LuxHeat 20 Sq Ft Heated Floor Mat

Best for: A compact installation where a pre-spaced mat and built-in GFCI thermostat are appealing. The 120-volt kit includes a 20-square-foot self-adhesive heating mat, cable monitor and alarm, OJ Microline UDG4-4999 programmable thermostat, and floor sensor. The listing says it can be installed under tile, laminates, and more.
The mat can be cut and turned, flipped, or rotated, but the listing warns not to cut or shorten the red heater wire. It also says the heating wires must be embedded in self-leveling underlayment, thinset, or mortar. Choose this over a cable kit when the stated mat format and 20-square-foot coverage suit the layout.
Buying Guide: How To Compare Electric Floor Heating Costs
How much floor area should the kit cover?
Measure the area you intend to heat and compare it with the kit’s stated coverage: 15, 20, 30, 40, or 150 square feet. Do not assume that the entire room needs heated flooring. A kit that is too small may not cover the intended zone, while excess coverage may not suit the layout. Check the manufacturer’s installation guidance for how to measure usable heated area.
What affects the total project cost?
The kit is only one part of a floor-heating project. Compare what each package includes, such as thermostat, sensor, GFCI protection, cable monitor, alarm, and uncoupling membrane. Installation materials and labor may also affect the total, but these product details do not establish those costs. Check current product listings and obtain installation estimates for your project rather than relying on a kit name alone.
Should you choose a mat or cable system?
A mat may offer pre-spaced heating wire and adhesive backing, as described for the 20-square-foot LuxHeat kit. Cable systems may be a better fit when the included cable and installation format match the layout. Confirm that the selected system works with your planned flooring and installation method; do not cut heating wire unless the manufacturer explicitly permits it.
Which thermostat features matter?
These options list programmable thermostats, and the 150-square-foot kit specifically lists Wi-Fi control. Other kits identify touch or programmable controls, sensors, and—in some cases—GFCI protection. Compare the controls you actually need, and verify the exact thermostat model and included safety components in the current listing.
What should you check before buying?
Verify voltage, coverage, included parts, flooring suitability, installation requirements, and electrical needs. Several products listed here are 120-volt systems, but that alone does not confirm that a particular home circuit is suitable. Consult product instructions and a qualified professional when needed.
Frequently Asked Questions

The 20-square-foot mat listing specifically says not to cut or shorten its red heater wire. Follow the instructions for the exact product you buy.
Do all kits include a thermostat?
The listed product names or details identify a thermostat for each of these options, but features vary. Verify the included model and functions in the current product listing.
