Tile and radiant floor heating

I just gutted my 1st floor bathroom, and installed a new subfloor. Now I want to add radiant floor heating, before I add the tile on top, but I am not sure what is the best option as I have come across several suggested methods and systems

1) On top of new subfloor place Electrical pad, covered by cementboard and then tile
2) On top of new subfloor place radiant track (1/2 pex snaps into track), covered by cementboard and then tile
3) Undermount (alluminum stapled up between joists and snap in pex) radiant heat, and add cementboard and tile on top of subfloor

Which is the best/ current method?

What are you trying to accomplish? Electric heat mats arent a primary source of heat. They basically warm the floor so its not cold to walk on. They augment the primary source of heat. A hydronic (pex) system is a primary source of heat and its design is to warm the entire space.

Will this be a primary source for heat or just a "foot warmer"?
