If you purchased a Digital Multi-meter from Warmup you will have 2 connectors as shown below. Please make sure that the contacts that will be plugged into the multi-meter are properly exposed as illustrated below. It is possible that you may have to remove some of the sheathing from the connector ends to expose them enough to make the needed contact with the multi-meter in order to receive accurate readings.
How long will my electric floor heating system take to heat up?
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.
Will the Electric Floor Heating System Work Without the Floor Sensor Probe?
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.
Can I connect more than one Warmup heater to a 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.
Can I cut my floor heating mat if it’s too large?
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.
Floor Probe Installation Instructions
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.
This page explains how to extend your lead wire or connect your heater to a thermostat in a remote location.
Can I install my Warmup system directly on top of plywood ?
This page outlines installation recommendations when installing over a plywood sub-floor.
This page will give you pointers about trimming your cold lead to fit easier in the conduit and electrical box.
The TDR Meter is used to measure the distance to an existing fault in the wiring of your heating system. It sends an electrical pulse into the connected cable, traveling along the cable until it reaches the fault and then that pulse is sent back to the TDR. The time it took for that pulse to reach the fault and travel back is measured and converted to a distance reading that will appear on the TDR Meter.
Was your electric floor heating system installed directly on a concrete slab?
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%.
What are the electrical requirements for my Warmup system?
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.
Do I choose cable or mat electric floor heating systems?
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.
Are you getting a “Ground Fault” error after a few years?
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.
What is the EMF level of Warmup electric floor heating cables?
Our cable was tested and measured 0.5 mG at 1/2” (a typical distance between the cable and your feet).
This measures at 1/200th of the acceptable value of 100 mG as established by the WHO and Intertek/ETL.
It therefore complies with EN50366.
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.

Should I use a 120V or 240V electric floor heating system?
As a rule of thumb, when you are using electric floor heating on an area over 130 sq ft, you will likely use a 240v system(s). Click “Read More” to find out why.
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.
Should I use Self-leveler or Thinset ?
Using self-lever or thinset depends on the type of flooring being installed and preference.
I nicked the wire slightly; do I need a repair kit?
When slight damage is caused to the wire, a visual assessment needs to be made. Read more.
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.
When a repair is completed, can I replace tile immediately?
After completing a heated wire repair it is safe to replace the needed tile. Make sure your resistance readings are correct before re-laying the tile after the repair is completed.
What do I need to prepare for my electric floor heating project?
Before you order your floor heating system, there are a several things you can do in preparation. Read this before your start!
How to install a floor heating mat around a drain in a shower.
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.
Can you heat under glass mosaic tiles ?
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.
