hi mate
changing an immersion heater is easy
first of all switch off the mains water as turning the gate valve on the cold feed doesnt always work and can pass water anyway
turn on all taps in the house to drain the tanks upstairs
when the water has stopped you then can change the immersion
turn off the main electricity and undo the live neutral and earth from the immersion stat then unscrew the immersion from its socket(BE SURE TO PUT SOME OLD TOWELS AROUND THE BASE OF THE CYLINDER AS THERE WILL BE RESIDUAL WATER BUT NOT TOO MUCH SO DONT WORRY)
you dont have to drain the whole of the cylinder
next take the new immersion heater and put the washer provided on and then get boss white from a merchants and put plenty around the thread screw the new immersion heater into the socket being carefull not to cross thread and tighten fully bu hand then get a hammer and just tap the spanner to fully tighten the immersion
rewire the live neutral and earth close all the taps and switch on the mains water again
job done
by the way i am a plumbing and heating engineer and have done this thousands of times
