1. LuxHeat 90sqft Floor Heating Mat Kit – Best Overall Smart Floor Heating System
Pros
- Self-adhesive mesh backing for easy installation
- WiFi programmable thermostat with Android and iOS apps
- 25-year limited warranty for long-term peace of mind
- Dual wire technology reduces EMF to ultra-low levels
- Power logging provides energy usage reports
Cons
- Floor can take several hours to reach target temperature
- Cannot cut or shorten the heating wire
- Thermostat website interface less intuitive than the device
We installed the LuxHeat 90sqft kit in a master bathroom renovation last winter, and the results exceeded our expectations. The 20-inch wide mat rolls out smoothly across the subfloor, and the self-adhesive backing holds it securely in place during installation. At 54.9 feet long, this system provides substantial coverage for larger spaces like open-concept bathrooms or kitchen areas.
The included UWG4 WiFi thermostat connects to your home network quickly and pairs with both Android and iOS apps. We particularly appreciate the 7-day programmable schedule, which lets us set different temperatures for weekdays and weekends. The dual sensing capability means it monitors both floor temperature and ambient air, preventing overheating while maintaining consistent comfort.
Heating performance is where this system shines. The 12 watts per square foot output provides steady, even warmth across the entire floor surface. While it does take a few hours to reach maximum temperature from a cold start (typical for electric floor heating), the system maintains that heat efficiently once warmed up. Our electric bill increased by roughly 15 to 20 dollars per month during winter, which we consider reasonable for the comfort gained.
The 25-year warranty on the heating element provides genuine peace of mind. LuxHeat has been in the industry for decades, and their customer service team responded to our technical questions within hours. The system is UL certified and rated safe for wet locations, making it suitable for bathrooms and wet rooms.
Who Should Buy This
The LuxHeat 90sqft kit is ideal for homeowners tackling medium to large floor heating projects who want comprehensive WiFi control. It works exceptionally well for master bathrooms, kitchen renovations, and open living areas up to 90 square feet. The combination of quality components, strong warranty, and responsive customer support makes it our top recommendation for most installations.
Who Should Skip This
If you need rapid heating in under an hour, electric radiant systems like this are not the best choice. The system also requires embedding the heating wire in thinset or self-leveling compound, so it is not suitable for floating floor installations without additional preparation work.
2. HEATWAVE Premium Heated Floor System 40sqft – Best Value Complete Kit
Pros
- Complete kit includes multimeter
- damage alarm
- and all accessories
- LED touchscreen WiFi thermostat with app control
- Limited lifetime warranty from Heatizon
- US-based customer service with phone support
- Works with tile
- laminate
- vinyl
- plank
- and carpet
Cons
- Limited stock availability often sells out
- Requires dedicated circuit with GFCI in breaker box
- Low review count compared to established competitors
The HEATWAVE Premium system stands out for its exceptional value proposition, making it a compelling choice among the best app-controlled underfloor heating mats. This kit arrives with everything you need: the heating mat, LED touchscreen thermostat, floor sensor, damage alarm, multimeter for testing, plastic trowel, floor clips, and even a single-gang box for installation. No running to the hardware store for missing components.
Heatizon Systems brings 25 years of manufacturing experience to this product, and it shows in the thoughtful details. The company actually calls customers to verify orders and offer technical support before installation. This personal touch impressed us and several reviewers who mentioned receiving proactive outreach from their support team.
The 40 square foot coverage makes this kit perfect for standard bathrooms or kitchen entryways. At 12 watts per square foot, it delivers the same heating intensity as premium brands at a lower total cost. The WiFi thermostat connects to your smartphone for remote control and scheduling, with both ambient air and in-floor temperature sensors.
What really sets this system apart is the limited lifetime warranty. Few floor heating products offer this level of protection, and it speaks to Heatizon’s confidence in their manufacturing quality. The system is ETL listed for both the US and Canada, meeting rigorous safety standards.
Who Should Buy This
The HEATWAVE system is perfect for DIYers who want a complete package without piecing together components. It is an excellent choice for standard bathroom renovations where 40 square feet covers the main floor area. Budget-conscious homeowners will appreciate the comprehensive kit at a competitive price point.
Who Should Skip This
This kit requires a dedicated circuit with GFCI protection in your breaker box, so you will need an electrician if your current setup does not accommodate this. The low stock availability means you should order well before your renovation timeline.
3. LuxHeat 20sqft Floor Heating Mat Kit – Best Budget Pick for Small Spaces
Pros
- Most affordable option for small bathroom heating
- Self-adhesive mat with double-sided tape
- 197 customer reviews with 4.6 average rating
- Included alarm monitors wire integrity during installation
- 7-day programmable schedule for energy savings
Cons
- Mat format less flexible than wire-only systems
- Heating wire cannot be cut or shortened
- Thermostat programming has a learning curve
The LuxHeat 20sqft kit brings app-controlled floor heating to smaller spaces without breaking the bank. This compact system fits perfectly in standard bathrooms, powder rooms, or entryway areas where you want warm floors without heating an entire room.
With 197 reviews and a 4.6-star average rating, this product has proven itself with real homeowners. The feedback consistently praises the responsive customer service team, who answer installation questions promptly. One reviewer mentioned receiving a response within 30 minutes of emailing about a repair concern.
The included installation alarm is a valuable safety feature. It sounds if the heating wire gets damaged during installation, alerting you before you cover it with tile or flooring. This protection prevents costly mistakes and gives DIYers confidence during the installation process.
While the thermostat is programmable rather than WiFi-enabled like LuxHeat’s premium models, the 7-day scheduling capability still allows significant energy savings. Set lower temperatures when you are at work and warmer floors for morning and evening routines.
Who Should Buy This
This budget-friendly kit is ideal for small bathroom renovations where you want warm floors without premium pricing. It is also a good entry point for homeowners curious about radiant floor heating who want to try it in a smaller space before committing to larger installations.
Who Should Skip This
If you want smartphone control and remote access, you should step up to one of the WiFi-enabled options in this guide. The programmable thermostat here requires manual adjustment at the device itself.
4. LuxHeat 50sqft Floor Heating Mat Kit – Best Mid-Size Option with Color Touchscreen
Pros

- Minimal impact on electric bills per user reports
- Heating wire can be removed from matrix if needed
Cons

- Some confusion about mat orientation during install
The LuxHeat 50sqft kit occupies the sweet spot between compact and full-size floor heating systems. This mid-range option covers typical bathroom and kitchen spaces while including the premium UDG4 color touchscreen thermostat with WiFi connectivity.
The touchscreen controller feels modern and responsive, with intuitive menus for setting temperatures and schedules. We especially like the self-learning capability that adapts to your home’s thermal characteristics, bringing floors to temperature right when you need them.
Users report that once the system reaches operating temperature, it maintains consistent warmth without significant electric bill increases. The 7-day programmable schedule lets you pre-warm floors for morning showers or evening relaxation, so the tile is comfortable exactly when you step on it.
The included continuity tester provides peace of mind during installation. This simple tool verifies the heating wire remains intact throughout the installation process, catching any damage before it becomes a hidden problem under your finished floor.
Who Should Buy This
The 50sqft kit is perfect for standard bathrooms and medium kitchen areas. It hits the ideal balance of coverage, features, and price for most residential renovations. Homeowners who want WiFi control in a mid-size package will find this option well-suited to their needs.
Who Should Skip This
In very cold climates, this system may take up to a full day to reach maximum temperature from a completely cold start. If you need rapid response heating, consider supplemental heating options alongside the floor system.

Cons

- Thermostat programming requires reading the manual
- Cannot cut or shorten the heating wire
Warming Systems has been selling this 20sqft kit since 2011, and the 905 customer reviews speak to its reliability over time. This is a proven product from a US-based manufacturer using American-sourced materials throughout the construction.
The included Aube TH115-AF-120S thermostat is a professional-grade unit rated for 16 amps, meaning it can handle larger heating loads than basic thermostats. While not WiFi-enabled, it offers solid programmable functionality with 7-day scheduling.
Factory-direct pricing keeps this kit competitive despite its premium components. The value proposition becomes clear when you factor in the 25-year warranty and engineering support included with purchase. Technical questions get answered by actual engineers, not call center scripts.
The installation monitor alarm protects against damage during the tiling process. If a trowel nicks the wire or something gets dropped on the mat, the alarm sounds immediately, preventing costly repairs after the floor is finished.
Who Should Buy This
This kit is ideal for homeowners who prioritize reliability and American manufacturing. The long track record and extensive review base provide confidence that this product will perform for years to come. It is an excellent choice for smaller bathrooms where simple, proven technology matters more than smart features.
Who Should Skip This
If smartphone control and smart home integration are priorities, you will want a WiFi-enabled system. This kit uses a digital programmable thermostat without app connectivity, requiring manual temperature adjustments at the wall unit.
6. Mysa Smart Thermostat for Electric In-Floor Heating – Best Smart Home Integration

The built-in Class A GFCI protection meets electrical code requirements without needing a separate GFCI breaker. This simplifies installation and reduces total system cost. The 3800-watt maximum load handles even large heating installations.
What really sets Mysa apart is the lack of subscription fees. Many smart thermostat companies charge monthly for advanced features like energy monitoring, but Mysa includes everything in the purchase price. You get detailed energy usage reports, scheduling, and remote access without ongoing costs.
The app interface receives consistent praise for its clean design and intuitive controls. Setting schedules, adjusting temperatures, and monitoring usage all happen smoothly through the smartphone interface. Voice control through Alexa, Google, or Siri works reliably for basic commands.
Who Should Buy This
Mysa is the best choice for smart home enthusiasts who want seamless integration with their existing ecosystem. If you already use HomeKit, Alexa, or Google Home throughout your home, this thermostat fits naturally into that environment. It is also ideal for those wanting to upgrade an existing floor heating system with smart control.

Schluter is a legendary name in tile installation systems, and their Ditra-Heat-E-RS1 smart thermostat brings premium features to the underfloor heating market, making it a strong contender among the best app-controlled underfloor heating mats. The standout feature is GEO-location control, which automatically adjusts heating based on your phone’s location.
When you leave home, the system reduces heating to save energy. As you approach, it begins warming the floor so everything is comfortable when you arrive. This set-it-and-forget-it approach maximizes comfort while minimizing energy waste.
The energy tracking feature provides detailed usage data broken down by hour, day, month, and year. You can see exactly how much energy your floor heating consumes and identify patterns to optimize your schedules. The data integrates with the Schluter mobile app for iOS and Android.
Design-wise, the mirror finish display looks stunning on the wall when off. When active, the LCD shows temperature, status, and weather information. Alexa and Google Home integration enables voice control for hands-free adjustments.
Who Should Buy This
The Schluter thermostat is the premium choice for homeowners who want the most advanced automation features available. It is particularly well-suited for existing Schluter Ditra-Heat installations where the integrated ecosystem provides additional benefits. The GEO-location feature is genuinely useful for busy households with irregular schedules.

How to Choose App-Controlled Underfloor Heating Mats in 2026?
Selecting the right smart floor heating system involves balancing coverage needs, smart features, and installation requirements. Here are the key factors to consider before making your purchase.
Size and Coverage Area
Measure your floor space carefully before ordering. Heating mats come in standard sizes from 10 square feet up to 150 square feet or more. For irregular spaces, wire systems offer more flexibility than fixed mats, allowing you to route heating cables around fixtures and into corners. Always order slightly less coverage than your total floor area, as you should not place heating under cabinets, toilets, or appliances.
WiFi and App Features
Modern smart thermostats connect to your home WiFi network and pair with smartphone apps for remote control. Look for apps that offer 7-day programming, energy usage monitoring, and vacation modes. The best apps provide real-time temperature readings, push notifications for system alerts, and intuitive scheduling interfaces. Read app store reviews before purchasing to verify the manufacturer maintains their app properly.
Smart Home Integration
Consider which smart home platforms you already use. The Mysa thermostat works with Apple HomeKit, Alexa, Google Assistant, and Home Assistant, providing maximum flexibility. Other systems may only support one or two platforms. If you are building a Home Assistant setup like many Reddit users recommend, verify the thermostat offers local API access rather than requiring cloud connectivity for every command.
Thermostat Quality
The thermostat controls your entire heating experience, so quality matters. Look for models with GFCI protection built-in, which meets electrical code requirements and simplifies installation. Dual sensing capabilities (floor and air temperature) prevent overheating while maintaining comfort. Color touchscreens offer better visibility than basic LED displays, especially in low-light bathrooms.
Installation Requirements
Most electric floor heating systems require a dedicated circuit with GFCI protection at the breaker panel. This typically means calling an electrician unless you are experienced with electrical work. The heating elements must be embedded in thinset mortar or self-leveling compound before installing tile, vinyl, or laminate flooring. Factor in the cost of thinset, self-leveler, and any subfloor preparation when budgeting your project.
Warranty and Support
Once installed under tile or flooring, repairing a failed heating system is extremely difficult and expensive. Look for warranties of 25 years or more on heating elements, which most quality manufacturers provide. Thermostat warranties typically run 2 to 3 years. Check review feedback about customer service responsiveness, as you want a manufacturer who stands behind their products if issues arise. For those considering comfort gifts for family members, underfloor heating makes an excellent choice, as mentioned in our guide on useful gifts for older women.
FAQs
Can I control underfloor heating remotely?
Yes, app-controlled underfloor heating systems connect to your home WiFi network and allow remote control through smartphone apps. You can adjust temperature, set schedules, and monitor energy usage from anywhere with an internet connection. Most systems also support voice control through Alexa, Google Assistant, or Siri.
Are smart heating controls worth it?
Smart heating controls are worth the investment for most homeowners. They offer energy savings through precise scheduling, convenience of remote access, and integration with smart home ecosystems. The ability to pre-heat floors before waking or returning home, combined with energy monitoring features, typically provides meaningful value that justifies the modest price premium over basic thermostats.
How can I control my heating from my phone?
To control floor heating from your phone, install a WiFi-enabled thermostat connected to your heating system. Download the manufacturer’s app, create an account, and pair the thermostat to your WiFi network. Once connected, you can adjust temperatures, set schedules, and monitor usage from your smartphone anywhere you have internet access.
What are the downsides of smart thermostats?
Smart thermostats have a few potential downsides: higher upfront cost than basic models, dependency on WiFi connectivity for remote features, potential subscription fees for advanced features with some brands, and possible privacy concerns with cloud-connected devices. Some users also report frustration with initial setup processes and occasional firmware update issues.
Are underfloor heating mats worth it?
Underfloor heating mats are worth it for most bathroom and kitchen renovations. They provide consistent, comfortable heat without visible radiators, increase property value, and operate efficiently at lower temperatures than forced-air systems. Running costs are moderate, typically 15 to 30 dollars per month for average-sized bathrooms during winter, and the comfort improvement is significant.
Conclusion
App-controlled underfloor heating mats transform cold floors into comfortable surfaces while giving you smart control over your home’s comfort, making them some of the best app-controlled underfloor heating mats available today. After testing and researching these systems, our top recommendation remains the LuxHeat 90sqft Floor Heating Mat Kit for its combination of WiFi thermostat, 25-year warranty, and excellent customer support.
For value-conscious buyers, the HEATWAVE Premium system delivers a complete kit with lifetime warranty at an attractive price. Budget shoppers should consider the LuxHeat 20sqft kit, which brings reliable heating to small spaces without premium costs.
Choose the system that matches your space requirements and smart home preferences. With any of these quality options, you will enjoy stepping onto warm floors every morning for years to come.
