There is that too. Although I think that is not necessarily entirely part of his improvising and a part of his devil fruit powers. Lightning has been known to cause fires, explosions and other similar damage where it strikes. Considering the amount of electricity and the fact that the discharge releases hot plasma, it would make sense that the electricity from Eneru would cause electrical heat. He is able to reshape metals presumably by running electricity through them thus superheating them in the process. That is why the metals he shapes hurt when Luffy touches them although he doesn't seem to make much use of it. He seems to prefer using the items he makes in more direct ways. I wonder if he could use the heat from his electricity to defend himself or attack.
