Is your flooring going to be glued down?  

If yes, then no vapor barrier is needed.  

Is this installation being done on a platform that moves (an RV, trailer or Tiny Home that is planned on being moved more than once)?  

If yes, then a vapor barrier is needed between the top of the Black Gold panels and the flooring material.  

Does the flooring material lack padding, or does it have a rough backing and is a floating floor?  

If yes, then a vapor barrier is needed between the top of the Black Gold panels and the flooring material.  

Do you question the waterproofing of the flooring material or expect that there may be spills?  

If yes, then a vapor barrier is needed between the top of the Black Gold panels and the flooring material.

The difference between a 15 watt/sf heat mat and a 12 watt/sf heat mat is the percentage of time it is turned on.  If a 15 watt/SF mat would operate with a duty cycle of 5 minutes on and 5 minutes off to maintain temperature, then a 12 watt/SF heat mat would operate at 6.25 minutes on and 3.75 minutes off deliver the same heat.  The cost of operation would be the same.

Simply put, a 12 watt/sf mat does not provide enough heat to maintain temperature at all times.
