Specifically, how is WarmWire different than SunTouch Mats?
Mats install faster in rectangular spaces and everything is preset for you. Mats add a fiber reinforcing to the thinset mortar and that makes your floor stronger. The mats have blue heating elements coated with a water resistant PEX polymer that makes them suitable for installation in a shower. The heating elements are factory-woven into a coated polyester mat with optimal 2.75 inch spacing and 12 watts per square foot output. WarmWire costs less per square foot than the mats and the installation works well with unusual room shapes. So, WarmWire is more popular in larger areas or rooms with angles, curves, nooks, or tight spaces that don’t fit well with mats. You can adjust the spacing of WarmWire to match the heat loss from the room.
