4 Best Thermostats for Heated Floors

It’s important that you realize not all of these thermostats will be a viable option for your specific in-floor heating system. It has to match your system’s voltage, so pay close attention to the specs as you weigh your options. 

Other than that, the best thermostat for heated floors just comes down to how much smart home integration you want, how much you’re willing to pay, and a few other factors. 

These are the top 4 in-floor heating thermostats on the market right now.  

1) Mysa For Electric In-Floor Heating 

• Price: $199
• Available at: getmysa.com, Home Depot, Amazon
• Rating: 4.57/5 (275 reviews)
• Why we chose it: Highest amperage, smart home support, comes with floor sensor & Class A GFCI

This high-voltage smart thermostat handles 16A of load, which works out to 3,800W of heating capacity at 240V. That’s 200W more than every other option on this list. More wattage = more floor coverage per thermostat, which translates to fewer units needed for your home. 

Coverage coupled with the affordable price of under $200 makes this the best heated floor thermostat as far as value for the money goes. But it also comes with a 10K ohm floor sensor (16-foot run). Mysa also works with existing sensors between 5K and 40K ohms if you're swapping out an older unit.

You can choose from two control modes, too. 

• Floor Mode: Targets actual tile surface temperature
• Ambient Mode: Targets the room’s air temperature. 

The other standout feature is Early On, which calculates how far ahead your system needs to start heating to hit your scheduled temperature on time. This way your bathroom floor is warm when your alarm goes off, not by the time you’re heading out of the house for the day. 

You can connect to HomeKit, Alexa, and Google Home without a hub/bridge. You’ll be able to set up 7-day scheduling, energy and cost tracking, and temperature alerts from within the Mysa app. It’s the best thermostat for heated floors across every category that actually matters. 

2) QuietWarmth Smart Thermostat

• Price: $192
• Available at: Home Depot, Amazon, other online retailers
• Rating: 3.7/5 (16 reviews)
• Why we chose it: Color touchscreen and WiFi under $200

QuietWarmth's THERMAEGH is the most affordable option on this list, albeit only by $7. It performs fairly well for its price, too. You get a responsive 4-inch color touchscreen with an intuitive scheduling system that breaks the day into four events:

• Wake
• Away
• Home
• Night

Adaptive start decides when to start heating your floor so they hit target temp when each event begins, much like Mysa’s Early On capability. You can set your Wake event for 6:30 AM and the system will start working when it needs to so you step out of bed onto warm floors.

This thermostat works with Alexa and Google Home, but not Apple HomeKit. Not a dealbreaker unless your household runs on iOS. The 15A rating at 120V or 240V is fairly standard, but the 10-foot sensor is a bit short - so measure carefully before buying. 

3) SunTouch SunStat CommandPlus

• Price: $208
• Available at: Home Depot, Lowe's, Amazon, SunTouch website
• Rating: 4.2/5 (21 reviews)
• Why we chose it: Biggest display, auto-detects voltage

If the best thermostat for heated floors is synonymous with display size, SunTouch is the top contender. It’s 4.3 inches, full color, and can be mounted in either portrait or landscape. 

The other reason we think it deserves a spotlight on our best heated floor thermostat roundup is the auto-voltage detector, which saves you the hassle of manually configuring the unit. It determines whether your system runs on 120V or 240V. You don’t have to figure it out yourself.

The catch is that the SunStat CommandPlus is thin on the voice assistant front. You get WiFi and the Watts Home app for remote scheduling. However, there’s no Alexa, Google, or HomeKit compatibility. You’ll have to upgrade to the ConnectPlus model for voice commands and automation - that thermostat is nearly $275.

4) Schluter Ditra-Heat-E-RS1

• Price: $348
• Available at: Home Depot, Lowe's, Schluter website
• Rating: 4.8/5 (4 reviews)
• Why we chose it: Purpose-built for DITRA-HEAT systems, Control4 compatible

It’s the most expensive on this list by far. But you could still make the case for the Schluter Ditra-Heat-E-RS1 as the best thermostat for heated floors. So what makes it worth the money? 

This model comes equipped with a mirror-finish faceplate, geofencing, and scene creation for coordinating multiple thermostats across zones. It also has Control4 integration, which matters if you want to automate your home’s comfort. It’s compatible with HomeKit, Alexa, and Google.

But at a nearly $350 price tag (depending on where you’re shopping), it can be quite frustrating to discover you have to buy floor sensors separately. You might be able to make an existing sensor work if it matches 10K resistance.

The other thing that might rule it out is the app experience, which a lot of customers complain about. Overall the thermostat has solid reviews, but the negative ones almost always point back to the app experience. 

Which is the Best Heated Floor Thermostat For YOUR Home or Business? 

You can feel pretty confident choosing Mysa as the best heated floor thermostat. However, there are a few things you need to double-check before you buy anything. The first is voltage. 

Voltage 

Most household in-floor electric systems are either 120V or 240V. All four thermostats we compared today can handle both. However, commercial buildings often use 208V. Mysa is the only option that supports that system.

Smart Home Integration 

Adjusting by voice (or through automations) becomes effortless once your heating schedule runs through Alexa or HomeKit. Mysa and Schluter cover all three major platforms, while QuietWarmth is missing the HomeKit integration. The CommandPlus by SunTouch doesn’t support any voice commands.

Amperage 

This dictates how much floor your thermostat can cover. While every other option caps at 15A, Mysa gives you a little more wiggle room at 16A. That matters if your mat or cable system pulls nearly 15A and you want a bit of a buffer.

Value 

Not the lowest price, but the best value overall. That would either be the Mysa In-Floor unit or the QuietWarmth Smart Thermostat. Both come in at under $200 and give you everything you need to seamlessly manage your in-floor heating system. 

The difference is Mysa has much stronger reviews and has a longer sensor. 16A vs 15A, too. The display is a bit more upscale and intuitive as well, and Mysa comes backed by a 5-year limited warranty so you can order it with peace of mind. It’s the best home smart thermostat for this type of system.

Frequently asked questions

Do you need a special thermostat for in-floor heating?

Yes. These heating systems require floor sensor inputs and higher wattages. The best heated floor thermostat supports line voltage and has built-in GFCI to automatically shut the system down if it detects a ground fault. 

What types of thermostats work with underfloor heating?

You need a line voltage smart thermostat with a floor sensor port to actually read floor temperature. It must have GFCI as well for safety purposes.

What are the best underfloor heating thermostats?

Mysa makes a smart thermostat for every heating system, including in-floor heating systems. It’s the #1 choice when you look at how many boxes it checks - system compatibility, ease of use, intuitive control, smart home integration, and value for the money.
