Can STRATA_HEAT™ Wire be used in shower applications?

Yes, however showers may only be 120v systems. When installing a STRATA_HEAT™ Wire system in a shower, it must be placed between two non-combustible materials.

Install the STRATA_HEAT Wire system on top of the sloped pan if shower base is a poured mortar bed. Then, skim-coated with thin-set and tile over. Do not install STRATA_HEAT Wire directly over the rubber moisture membrane. We also advise against embedding STRATA_HEAT Wire in the mortar bed as long heating times could ensue. In the case of building panels such as backer-boards or HYDRO BAN® Board, you can install STRATA_HEAT Wire directly over the boards. Please refer to the corresponding installation manual for more information.

Can I cut the STRATA_HEAT™ blue heating element (wire) if I have too much left over?

No, you cannot cut the STRATA_HEAT wire for any reason. If you cut the wire, you could possibly permanently damage the wire. However, if you have too much floor heating wire for your floor configuration there are some options.

First, it is best that you carefully measure your desired heating area prior to ordering your product to avoid unnecessary installation delays.

If you have excess wire, it is possible to adjust the spacing of your wires. For example, if the wires are spaced at 3 (76mm) apart you can adjust the spacing to be closer. Note: Make sure that you never space the wires closer than 2" (50mm).

If you used a 4" (102mm) border, make it a 2" (50mm) border instead. Place the wire in sections of the room not currently covered to use up additional wire. Always remember not to place the wire under any permanent fixtures and not positioning them closer than 2" (50mm) apart.

In some cases you may have simply miscalculated how much floor heating wire was needed and you just have too much. In this case you will have to re-measure your space and request a different size.

As a reminder, it is vital that you carefully measure your desired heating area prior to ordering your product to avoid unnecessary installation delays. Failure to comply will void any warranty or claims.

I slightly nicked the STRATA_HEAT™ Wire. Do I need a repair kit?

The STRATA_HEAT Wire consists of two inner conductors, each insulated, then surrounded by a ground braid and a final cable jacket. A very slight scrape to the cable may only reveal the ground braid. If that is the case, it should be sufficient to shrink wrap the area tightly. If that is the case, it should be sufficient to shrink wrap the area tightly. However, if any damage has been made to the braid, a proper repair needs to be completed. Any damage, however slight, could result in issues down the road. But so could an improper repair, so it is up to the installer to weigh the pros and cons and the level of cable damage.

Why does my floor feel warmer in some spots?

Your floor can reach higher temperatures in some areas where furniture, area rugs, dog beds or other fixtures are trapping the heat. Avoid placing thick mats, rugs and floor level furniture on your heated floor, specifically in the area where the sensor probe is located. These restrict the transfer of heat away from the cables and result in the floor area beneath them being warmer than other areas.

Warmer spots can also be caused if wire spacing is closer in some parts than others. Make sure the wire is spaced consistently at the time of installation. Additionally, this can result if the installation has more mortar or self-leveling over the wires in different areas.

Wire spacing and levelness of the floor can make a big difference. If wire spacing and floor height isn’t consistent, your floor may not heat evenly.

Where must the factory joint of STRATA_HEAT™ Wire be installed?

The factory joint MUST be installed in the floor. 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. To help with the height the joint adds, consider cutting a channel in the sub-floor for the joint. This will help avoid adding height and maintain levelness in the floor.

What is the Electric Magnetic Field (EMF) level of STRATA_HEAT™ Wire?

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. Any value under 100 mG is typically defined as having no measurable impact on humans.

EMF concerns were related to high frequency items such as industrial equipment and high voltage lines in residential areas. Not microwaves, cell phones or floor heating systems. Human exposure to EMF is not an issue at these very low levels.

Keeping in mind that floor heating industry products will measure around 2 to 3 mG (up to 19 mT for single-core cable) and at times below 1 mG, here are some comparative levels of EMF;

  • Vacuum Cleaners 300mG
  • Microwave Ovens 200mG
  • Dishwashers 20mG
  • Electric Dryer 3mG
When measuring the EMF of floor heating cables, the reading will vary whether measured on single-conductor or dual-conductor cables. So the important consideration as a consumer is whether you’re considering a “single core” or “dual core” cable product. All STRATA_HEAT™ Wire systems are dual conductors.
