hi

so for now im going to fit the old immersion heater
wireing back together
its old say about 20 years the immersion heater is still in the tank
its just acase of putting the wires back
can anyone see a problem with this
Thanks
Mick

Ours was put in as a standby twenty odd years ago and was never needed.
I eventually diverted the circuit for other purposes, but made sure I
could restore it in minutes should it ever be needed for its original
purpose.

If yours is just a matter of reconnecting and you know what you are
doing, just get on with it - there should not be a problem.
