If insulating backer board is not installed there should be insulation in the subfloor to assist the performance of the heating system. A 160 w/m system is perfect for a warm tiled floor on uninsulated concrete subfloors, but up to 30% of the heating will be absorbed downwards into the concrete slab without a thermal barrier such as insulating backer board.
