I recently bought an electric heater from argos. It is working ok but
when switched on/off at the wall socket sometimes a spark is seen
inside the socket. The house was re-wired a couple of years ago and is
all properly fused etc.

Is this normal behavior for an electric heater / does it indicate a
fault and should be replaced?

How can you see a spark inside the socket when you switch off the
socket or do you mean you can see the spark inside the unused half of
a double socket or are you just pulling the plug out with the socket
switch in the ON position? *

I see a light through the plastic socket cover and sometimes see the
spark through the gap the switch sits in.
