Hello, here's my situation:

In an upstairs bedroom, there was a baseboard heater plugged into one
outlet and, in another outlet, a hair dryer and hair iron. Poof, all
outlets went dead and the holes of the outlet where the heater was
plugged in was scorched and slightly melted.

That's one reason why baseboard heaters are supposed to be hardwired
and on a dedicated circuit. Someone jerry rigged that heater by
putting a cord and plug on it.. You should seriously consider getting
that baseboard heater properly wired. You may not be so lucky next
time. JMHO.
