Yes those stand alone heaters are no better than paraffin heaters for
condensation. I remember during the years of the rolling power cuts when
most people used on or the other that condensation and mould growth was a
nightmare unless you opened windows, which in mid winter of course meant
draughty rooms or possible carbon monoxide dangers if you sealed the room.

A balanced flue would be feasable.
