Try heating it with your gas bottle for a bit (about a minute or so), but take it easy. That normally works, but not every time.
Good Luck.

Mark theres a spray on the market now that works initially as a freezer spray thus shrinking the core element but simultaneously sprays oil and solvent (like WD40 and 3 in one) and since the cold burst creates a gap that the lubricant can get into theoretically allows good/better penetration. worth a try.

A decent immersion spanner and a tap with a hammer before youdrain down normally does it for me.

thats what id try but dont try it when the cylinder is empty
if that doesnt work drain it remove all wiring, stat and plastic from the element then apply plenty of heat
there usually stuck because of the jointing paste and heat will soften this
worse case scenario is getting the washer cut out between the element and the cylinder flange with a hacksaw blade spray with wd then retry all the above
in thity five years ive only mashed one cylinder using the above

will you damage an empty cylinder in this way?

Yeh mate when you try and remove the heater from and empty cilinder you can buckle and twist the thin walls of it, when its full of water it makes it more dense and less its likely to cave in.
