You may want to use a transformer to adjust the mains voltage to something which runs the regulators with a bit less voltage drop so the heat from them is no more than necessary.

Usually transformer windings are scaled to make enough overhead voltage for the worst-case mains input voltage and a set fully loaded with options like ISB.
