I am having real difiiculty in removing a failed heater element from the cylinder. It is the upper of two 14inch 3kw type. The lower element has never been connected as there is not sufficient current available, so the upper one, now failed, provides all of the hot water to the flat. I am using a box-spanner but am reluctant to exert too much force in case of distorting the cylinder. I left this on Friday evening (two days ago) having been given a liberal spraying of WD40. Today I returned believing it could be removed. It didn't. I have left it once again doused in WD40 and intend to return tomorrow. Are there some elements that simply cannot be withdrawn 'cos it has become fused to the cylinder by the limescale? Don't really want tot have to put in a new cylinder?
Any advice much appreciated.
