Suntouch Vs Warmlyyours

SunTouch Floor Heating vs. WarmlyYours Floor Heating

SunTouch and WarmlyYours (TempZone) are both using a heating wire secured to a supporting material, still, there are major differences between these two electric floor heating systems.

In this section you will see why SunTouch is your best choice for your floor heating.

Heating Wires

Heating Wires (The Heart of the System)

SunTouch uses twin, multi-stranded, oxygen-free copper heating elements for redundancy, longevity and to reduce Electro-magnetic Field (EMF) for safety.

Products using a single heating element, can produce from 150 to 350 times more EMF than SunTouch.
uses Aramid to reinforce and add longitudinal strength to their heating wires, in case the wire is pulled during or after installation. Our dual-wire technology also allows us to start the mat at the thermostat and end at any other location in the room

A single-wire product such as WarmlyYours - TempZone MUST begin & end at the same location to complete the electrical circuit, making the installation more complicated.
Our PEX jacket material has been successfully used in radiant floor heating applications for over 30 years. We also use a fully shielded grounding jacket around our heating elements and it extends up our power lead to the grounding wire in the junction box for the thermostat. This gives SunTouch the highest degree of safety as well as using our power lead without a conduit in remodeling situations, as it is equal to romex wiring.

Heat Output

SunTouch has a heat output of 12 Watts/sq. ft. This allow us to cover up to 150 sq. ft. from one 120 Volt thermostat.

WarmlyYours - TempZonehas 15 Watts/sq. ft. products and the can only cover up to 120 sq. ft. before needing a second thermostat.
SunTouch at 12 Watts/sq. ft. produces over 40 Btu/Hr/sq. ft. With over 25 years of radiant floor heating experience, we know most room heat losses are around 30 Btu/Hr/sq. ft., and floor warming requires even less heat, so 12 Watts/sq. ft. is more than sufficient in a reasonably well insulated home.

Open Weave Design

The heating elements in a SunTouch mat are woven to the underside of the mat, which we feel is more secure than just attaching with a thread.
Our mat allows itself to be flipped and turned 90 and 180 degrees to fill in virtually any shape and the wire can be easily released and attached to the floor to fit angles or curves.
Our open weave mesh is 85% open, which meets the TCA & ANSI recommendations for 80% thinset contact with the substrate & the tile or stone surface above. This open mesh allows the thinset to more fully bond to the surfaces above & below the heating mat.

SunTouch received a moderate-commercial rating from testing at Tile Council of America (TCA). Moderate-commercial is approved for anything except for vehicular traffic (automobiles, fork trucks, etc.).

Wire Spacing

Wire spacing is typically determined on not exceeding the UL maximum allowable exterior wire temperature for a floor warming application which is 90 degrees C. Since SunTouch uses 12 Watts/sq. ft., we can space our elements further apart and still meet the UL temperature limit.

Wire spacing is not the main issue in laying out a floor. For example, when heating a bathroom floor, the mats should start at the vanity and then go to the wall as the vanity is the critical space to heat ones toes. The spacing away from the wall can vary from 2" to 8", depending on the specifics of the layout. Also, the SunTouch dual-wire has twice the heating elements per foot as a single-conductor wire, which results in a lower element temperature and greater longevity.


Our Loudmouth was the industry leader in monitoring floor warming mats during installation. With our dual-wire design, the mat can be tested the entire time during installation. Single-wire designs can only be tested when the two ends are brought back together at the thermostat. So if a single-wire product is damaged during installation before a monitor can be attached, then the installer doesnt know where the product has been damaged. Also, our Loudmouth has a test button & green battery indicator light to let the installer know if his battery is working properly.


The SunTouch warranty is now 25 years. WarmlyYours - TempZone is 10 years.
