When you are hanging from the box spanner. Just be careful not to twist the whole cylinder.

I also find if it is too stiff. Try tightening it up more then undo.If it is really stubborn ( and it will be) then cut away some of the foam and apply heat to aid in removing them.
ok....centralheatking guide to changing immersion heater element...others will chip in
turn cold water supply off to cylinder, let a couple of litres water out of hot tap. Leave rest of water in cylinder to keep it strong. turn lecky off and undo the 3 wires then with proper immersion box spanner undo immersion, it will resist,,, smart tap with decent hammer.
a little bit of water might appear as you undo unit. remove unit ...measure it and or go to plumbers merchant not bq get like for like plus a new stat. and small tub of boss white. smear boss white on thread carefully hand twist unit back into cylinder then nip up with box spanner. turn water on check for leak. re connect wires switch on listen to unit heating up. check temp and adjust thermo as required . sit down pat self on back open 1st of 4 beers bought on way back from plumbers merchant

Also your cylinder immersions are side entry so once you have got the immersion cracked(moving) drain it from the drain point to below the immersion level. (Scoop out any scale if there is any when you change it and make sure you get the right type of immersion for your water hardness)
Hello Rob,
I know that You have just missed this when writing your `Guide` to replacing an Immersion Heater - I am not `being funny towards You` - but just in case the OP does exactly what you wrote:
As the OP`s Immersion Heaters are on the side of the Cylinder He will need to drain off more than `let a couple of litres water out of hot tap` or he will be in trouble when the Immersion Heater is unscrewed.
OP / WesternPathfinder - You will need to drain the Cylinder to below the Immersion Heater point before unscrewing it.
