Heating wires are protected by GFI thermostats
The heating wires are protected by GFI thermostats for the heating cable or matts. I'm not an expert but I believer this is safer than electric baseboard heaters.
I have looked into many different heating options over the past year and have chossen for my home to install an old school boiler and column radiators.
I found many wall hung electric fan heaters and electric radiator heaters available. If you are concerned with this install an electric wall hung heater a couple feet of the basement slab.
