Why do I need a floor heating thermostat?

The thermostats we offer are specifically provide optimal control and safety for electric radiant floor heating units. Unlike HVAC and other thermostats, these stats are designed to handle high voltage (either 120v or 240v) and have built-in Class A GFCI, which is a requirement for all electric radiant floor heating systems.

What does GFCI mean?

GFCI stands for “Ground Fault Circuit Interrupter”. It’s a safety device that terminates electrical power to your radiant heat system immediately in the event of damage to a wire or other catastrophe. A GFCI is required by electric code for floor heating applications just like it is required in most North American bathroom outlets. All thermostats sold at Warm Your Floor have built-in GFCI protection.

I need to replace an old thermostat.  Will the new thermostats work with my older system?

Yes, all of the new thermostats are compatible with older mats, cables, and sensor wires. Simply turn off the breaker, unwire the old thermostat, wire the new thermostat up, and turn the power back on. Your system will work like new. (See instructional photos below.)

How do I install a new floor heating thermostat?

Upgrading your thermostat is easy and just about any homeowner can do it by following these simple steps.

For more specific instructions, please consult the manufacturer's installation guide provided with your new thermostat.

Can I get a replacement faceplate if my thermostat is not working correctly?

The two parts of each thermostat are made together, and the manufacturer only supplies them in sets.

But keep in mind, replacing the faceplate likely would not solve the problem anyway. Thermostat errors usually start in the back panel of the device or in both the faceplate and the back panel. Very rarely is there an issue with the faceplate only.

If you are receiving an error message or your thermostat does not work properly, contact the manufacturer for help. If your product is under warranty, contact the manufacturer and they will replace it for you or give you a claim number you can use to get a replacement from us.

Can one thermostat control 2 or more heating mats or cables?

Yes. You can connect up to 3 mats or cables to one thermostat as long as their combined AMP draw is less than 15 (which totals about 150 sq ft of heated area for a 120V system and 300 sq ft for 240V system.

Can a thermostat run two mats or cables at different times/temperatures?

No, thermostats run all mats and cables hooked up to them as a single system, meaning they will all activate at the same time and heat to the same temperature.

What does it mean for a thermostat to be Dual Voltage?

All the thermostats we carry are now dual voltage, meaning they can be used with either 120v or 240v systems, so you never have to worry about ordering the “wrong” thermostat for an installation.

Can mats of different voltages be controlled by the same thermostat, since the thermostats are “Dual Voltage”?

No, dual voltage means the thermostat can be used with either a 120v or 240v system, but the voltage coming into the thermostat from the breaker must always match the voltage of the heating elements attached to the thermostat.

    Does the thermostat have to be the same brand as the floor warming unit installed?

    • Author: Jacquelyn S. Posted: November 8, 2016

      Hello Kristina,

      Thank you for your question!

      All of the thermostats we carry are compatible across all brands of the floor warming elements we sell.

    Is it possible to perform a software upgrade on a SunTouch Command thermostat, and if so, how is this accomplished?

      Hi Dan,

      SunTouch pushes automatic updates directly to the units as they become available.

    I am considering one 24" x 96" mat for our bathroom. Is 120 volt or 240 volt better.
    How long does it take to heat a 120 volt mat?

      Hi Anne,

      There is no difference in the heat output of the 120v and 240v heating elements, so we would recommend 120v for a mat of that size. 240v is recommended only for areas over 150 square feet or if 120v is not available. The startup time of each system is different depending on the heat loss of the room, but programmable thermostats learn to compensate for that over time, so as long as you use one of those, it will not be an issue.

    Can I use Nest Third Generation thermostats with your product? I have a mixed house, forced air and radiant, and would like one standard thermostat for both.

      Hi John,

      As of right now, the only floor heating thermostat that can fully integrate with the Nest system is the Nuheat Signature. Click here to view its products page & place your order.

      Please don't hesitate to contact us if you have any additional questions!

    Regarding a new pour slab heat install - Can the thermostat sensor wire be run through the same conduit the heating cable lead runs through?

    • Jacquelyn Sutterman
      Author: Jacquelyn Sutterman Posted: May 3, 2017

      Hi Dave,

      No, you will need to run the power lead for the heating cable in its own conduit. The sensor wire can be run in a separate conduit or outside of the conduit since it is a low voltage wire.
