Had the electrician fish the wires to the electrical box, and then I completed the hook-up once the heat mat was installed. After reading the instruction manual (it sure helps to read it) I scrolled down the list of options one-by-one and was done in about 5 minutes. Easy as can be. We ran it for a day or two just to make sure and then shut it off until cool weather returns. Makes a nice nite-light too.
The thermostat was pretty easy to install and it worked fine. Warm ceramic tile again!! However, I expected the equipment to be acceptable. It is easy to program and works very well.
What impressed me was that WYF provided very good service instructions and the price was quite reasonable. I received the product in less time than expected and they emailed me at each stage of shipment including telling me the day it would arrive.
