Something still needs to be fixed. There is no way to tell from
looking at the panel, that different phases are required.
As I said in another pose, it shouldn't be too hard to rewire an
outlet, eliminating the (shared neutral) situation. I'll do that.
First, I'd replace the dangerous and illegal [for this use] 12-2 cable
with 12-3, with the red and black wires connected to a two-pole 240V
breaker. Then I'd wire the space heater across the black and white, and
the hair dryer across the red and white.
That's 15A in the black wire, 14A in the red wire, and (15A - 14A) = 1A
in the white wire.
If you don't understand how that works, and why it's safe, and why the
setup you described is not ... then you oughta stop offering electrical
just enough to be dangerous. But in any wiring or other repair, I don't go
by what will 'be safe for me, because I know how it is set up.' I go by what
will be safe for any guests, or for the next owner of the place. A wiring
setup can easily be in place for 50+ years or more. Are <you> gonna be
around that long, to make sure everyone knows about your 'good enough'
shortcut? Spend the few extra bucks, wire it to code or better, and never
have to worry about it again. If nothing else, when it comes time for you or
your heirs to sell, the buyer's inspector will likely catch it anyway, and
you'll have to pay more to redo the work at that point.
