Common Support Questions
If I have extra cold lead wire, can I trim off what I don't need for my installation?
Yes. Unlike the heating cable for electric floor heating, the cold lead wires can be trimmed.

What breaker and wire size do I need to use for a floor heating system?
The breaker and wire sizes are selected based on the total amperage of the WarmlyYours heating system connected to a single thermostat. This information is on the WarmlyYours heating system's installation plan, electrical plan, or UL label. Based on guidelines from the National Electrical Code: loads up to 16 Amps may utilize 12 gauge wire with a 20-Amp breaker, and loads up to 12 Amps - 14 gauge wire with a 15-Amp breaker. Local code and/or other factors may change these guidelines.

Do I need to apply a layer of thinset over the subfloor first?
Yes, using a square-notch trowel (1/4” x 1/4” or larger), apply a layer of thinset to the subfloor area which will later be covered by the WarmlyYours TempZone™ Flex Roll, Easy Mat or Custom Mat.

What is the warranty for the TempZone™ floor heating system? Do you warrant the cost of replacing the flooring installed on top of the system? What if there was a surge that damaged the system?
WarmlyYours’ 25-Year No Nonsense™ Warranty is the most comprehensive warranty in the industry. In the event of a defect, we cover not only the repair or replacement of the TempZone™ system, but ALSO any labor costs AND flooring materials required to perform the repair. We do not cover the cost of flooring that needs to be replaced in the event of a repair necessitated due to damage. If a product is damaged by a power surge, that would not be covered by our warranty

How many square feet of floor heating can be connected to one thermostat?
One thermostat can control multiple heating mats/cables as long as all the heating elements are using less than 15 amps:
TempZone™ will cover aprx. 120 sq. ft. for 120V systems and 240 sq. ft. for 240V systems on one thermostat.
Environ™ will cover aprx. 150 sq. ft. for 120V systems and 300 sq. ft. for 240V systems on one thermostat.
Slab Heat will cover aprx. 90 sq. ft. for 120V systems and 180 sq. ft. for 240V systems on one thermostat.

Is the waterproofing above or below the heating wire?
Waterproofing for the room is in the layer above the floor heating system. The layers for waterproofing this type of floor are:
- subfloor
- thinset
- uncoupling membrane
- tempzone heating cable
- waterproofing tape for seams and corners
- thinset or self leveling cement
- tile floor

What if I have cracks in my concrete slab? Will that affect the floor heating installation?
Make sure any cracks or raised edges are sanded down before installation. Seal and patch cracks where possible. If needed, pour a layer of self-leveling cement to make sure surface is level and flat. Then proceed with instructions to install desired floor heating system and flooring.
It is strongly recommended that an insulating underlayment be installed between the slab and heating element to prevent heat loss.

Can the floor be waterproofed and still have floor heating?
Yes, we offer several options to help make your floor heating system water resistant or waterproof. Our TempZone product line is designed for wet areas - making it completely safe for rooms that will have water on the floor at times or may experience leaks or flooding. We also offer waterproofing bands for our TempZone Cable + Prodeso Uncoupling Membrane system. Allowing you to waterproof all seams and the perimeters of the wall - guaranteeing that your floor heating system stays safe and prevents water from leaking to areas below.

How do I determine if our heating cable is a Single Conductor or Twin Conductor?
Single Conductor vs. Twin Conductor Identification
- A single conductor floor heating system is a loop of one core wire, it starts at the thermostat and ends at the thermostat - this is the original method of manufacturing heating cable. Most single conductor floor heating systems have the same color cold lead wire connected to both load terminals/pigtails of the thermostat. Some early single conductor floor heating systems were produced with a white and a yellow cold lead wire.
- A twin conductor floor heating system terminates two core wires at the end, both wires start at the thermostat - this is the current method of manufacturing heating cable. Most twin conductor floor heating systems will have two different colored cold lead wires, and one of these is black. The other wire in a WarmlyYours floor heating system is either yellow (120V system) or red (240V system). A few early Environ systems had two black cold lead wires.
Note:
- Not all heating cables are wired directly to the thermostat. It may have been necessary during installation to terminate the heating cable in a junction box, and then run a separate (contractor-supplied) wire from the junction box to the thermostat.
- WarmlyYours single conductor cold leads were produced with a 13‘ length at the start of the loop, and a 26‘ length at the end. The 120V floor heating systems had a yellow and a white label attached to the cold leads, and the 240V floor heating systems had a red and a white label attached.
- If you have a single conductor floor heating system and notice that one cold lead is thicker or feels hotter than the other, please contact technical support at +1 (800) 875-5285

Is installing reflective insulation effective for making an electric radiant floor heating or snow-melting system more efficient?
Reflective insulation is not effective with conductive heating, which is how embedded floor heating and snow-melting systems transfer heat. To be effective, the reflective insulation surface needs to face an air space (air gap), which allows the reflected heat to be redirected.
An effective solution considers the insulating material's R-Value. This is the rating of a material's insulating properties. The "R" stands for "resistance" and refers to the material's resistance to heat flow, or temperature conduction.

What is the total power/amperage that the TempZone electric floor heating system draws and does this system need a dedicated circuit?
The amount of amperage draw depends upon how large the area is that you are heating. For coverage of areas less than 30 square feet, a 120V TempZone system will draw less than 4 amps. If you have a larger area over 240 square feet of heated space, then you will need a larger breaker plus additional controls. No matter what the size of the area you choose to heat, we recommend a dedicated circuit for your electric radiant floor heating system.
