1. SunTouch Tape Mat, 120v, 24"x7'6"
2. SunTouch Sunstat Non-Programmable Dial Control
Installation was on a minor renovation of a guest bath, under ceramic tile on concrete slab floor. My installer was a young man, just starting in the general contractor business who had not done a radiant floor before. He and I viewed the install video and read all the guidance and did the install together.
Installation: I did most of the wiring. My contractor decided to lay the mat with a minimal layer of thinset, then let that harden before laying the tile on top. He was concerned with having to lay tile over the mat only attached to the floor with the tape. Only complication was that the floor was then not perfectly smooth (thinset over mat somewhat irregular) but by having the mat firmly installed the tile setting task wasn't so critical in care to avoid the loose mat. I checked wire integrity before, during, and after it was set in the thinset.
Operation has been checked and is fine.
I plan a future remodel of the master bath and will install a much larger area of mat, and will use a more standard programmable thermostat because I will depend on the mat for supplementary heating in the bath area. I have installed solar electric and planned for additional power consumption so power use will not a factor.
Your install video and installation instructions were very helpful.
