This is explained in the answer to the question "Why does a neutralization reaction occur?"

The formation of the strong covalent H-OH bond of the water molecules, from opposite charge #H^+# and #OH^-# ions causes the exothermicity of the reaction and the fact that the amount of evolved energy per mole of water formed is more or less the same independently by the nature of the acid and bases that are neutralized, if these are strong.
