No, unfortunately you cannot use one 240V circuit to supply power to ALL controls / heating mats. Since the thermostats have GFCI protection built-in, those areas / heating mats will need to be supplied with Non-GFCI Protected Circuits.
StickyMat System – DWM
Home / Bathroom Collection
Warmup’s radiant electric floor Heated Mats, also called “StickyMat”, or DWM, is an electric underfloor heating mat system. Installers install our heated mats in regularly-shaped areas. In addition, users find our heated mats provide even heat distribution as they are manufactured with the utmost superior material.
Sheet vinyl is a great solution over an underfloor heating system as long as the vinyl does not have insulating properties greater than R1.5.
There is no limitation for covering an underfloor heating system, however, the thicker the materials and floor covering, the longer your system will take to heat.
You will want to review these electric heating mat system installation tips before you begin your electric floor heating installation project. Tips such as how the factory joint is positioned to how to extend the unheated lead. Click “Read More” for details.
While you must NEVER cut the wire, the mat system is designed to allow you to separate the wire from the mesh. The unusable mesh can be cut away from the mat. Now that you have freed the wire, you can install the wire around the area using hot-glue or tape to secure the cable away from any drains or screw-mounts.
If it is not installed in the floor, the joint may give and your system will no longer work. Not only will your warranty be voided but you will have to repair the joint and place it back into the floor. The joint connects the heated wire to the unheated lead. NEVER leave the factory joint exposed to air and do not place it in or behind the wall.
This page discusses the recommended practices of installing Warmup mats or cables in a shower.
There is no neutral leg on a double pole breaker and the polarity between the two sides does not match. This will cause the thermostat to trip and/or it will send too much voltage into a 120V heater.
Connecting one system to the other in series is often referred to as “daisy chaining”. Each floor heating system must be connected individually to the operating floor heating thermostat.
As long as all systems that connect to the thermostat do not exceed 15 amps, running multiple leads up the conduit to the thermostat location is completely acceptable.
We highly recommend the use of polymer-modified adhesives, also known as “modified thinset.” Since the addition of the polymer compound creates a more dense bonding reaction during the curing process, this ultimately improves heat distribution. Acceptable tile adhesives include modified polymer self-leveler or thinset.
It depends on a lot of factors, but a classic installation over ¾” plywood with NADWM mats would take about 30 minutes to heat from 60F to 80F. Click “Read More” for details.
This page explains the difference of the mat and loose cable options but ultimately either the cable or mat option will give you the design freedom you are looking for.
Without a thermal break, the concrete acts as a heat sink. Therefore, the heat is drawn first into the concrete sub-floor before your floor covering. This is why Warmup recommends installing Warmup Insulation Boards over the concrete sub-floor to act as a thermal break. This forces the heat radiate upwards first rather than down into the concrete slab. Warmup insulation boards can increase ramp up time by over 70% and decrease heat loss by over 90%.
Instead, try pulling the cable off the mesh and spacing the cable every 2 or 2.5 inches apart. Consult your installation manual with further questions regarding where the cable or mat can be run.
That “Ground Fault” error on your thermostat after several years could indicate your floor heating system had been damaged during installation. Click “Read More” to learn why.
The thermostats come with a 9’ sensor cable to detect the temperature under the floor finish. The end of the probe wire contains a capped sensor that should be evenly centered between two heating cables at least 12” into the heated area. At no time should the probe wire cross the heating cable.
Warmup electric floor heating mats are designed to make installation easy. Take a peek at our brief installation video to see for yourself. Click here to view it. To view a demonstration, watch our video on heating mat installation below.
While you can operate your floor heating system without the floor sensor probe it is better to have it installed. Click “Read More” for detailed information.
Please verify that the circuit can handle the amount of amperage your heating system requires. Your thermostat can only handle up to 15 amps so if you are connecting multiple heaters to one thermostat location, you may need to use a relay and a larger breaker. Your or your electrician can find out the amperage rating of your specific floor heating system in installation manual or printed on the box. Note: Just because the Warmup thermostats are dual voltage, this does not mean you can supply any voltage to your heating system. You must supply the voltage supplied to the voltage of your specific heater.

Welcome to our guide on testing the resistance of floor heating system wires using a digital multimeter. To ensure that your floor heating system will function properly, always test the resistance of your wires with a digital multimeter set to 200 ohms before, during and after installation. Let’s dive into the steps of how to check the resistance readings of your electric floor heating system to help you get started.
The Warmup DCM-PRO or StickyMat system may be used under carpet tiles as long as it is embedded in latex based modified polymer self-leveling compound prior to the installation of the carpet tiles.
The megger is used as a quality control measure to test the insulation resistance to detect any fault in the heater cable jacket. Such leaks cannot be spotted with a regular ohmmeter and help spot any damage to the cable and cable jacket.
Thermostats with an internal GFCI including the Warmup 4iE and WUDG will fulfill this requirement. If a non-GFCI thermostat like our Tempo thermostat is being used, a GFCI breaker will be required. Consult with your local electrician to make sure your installation is properly protected and meets National and Local Electrical Code.
If using a DCM-PRO membrane, scrape/scratch and prime the vinyl to ensure bonding with a highly modified thinset and install the membrane directly to it.
Yes you can heat under glass tiles. The thin-set holds the heat. The glass (silicon) isn’t a very good conductor but the thin-set does the work.

This page will give you pointers about trimming your cold lead to fit easier in the conduit and electrical box.
