    The HW tank below must be about 50 perhaps 60 years old. The less than a year-old element appears to have failed (not giving a consistent 20 ohms or thereabouts, in fact the reading on the multi-meter jumps around). The owner tells me the element was installed by an electrician who had quite a bit of trouble dealing with the amount of scale in the bottom of the tank. What is clear is that he did not attempt to remove the access panel, presumably thinking that it could prove very difficult to reseal back in position after changing the element. No doubt there is a gasket of some sort which presumably will disintegrate upon dismantling.


    It might be entirely preferable to replace this steel tank with a more current GRP equivalent but I am off on holiday in a couple of days and am pretty short on time. Also I am not sure I can source this sort of thing very quickly. It is probably going to be bloody heavy anyway. I would replace element with a titanium equivalent.

    Would anyone have any views as to the best thing to do here?

    1) Replace tank with something more contemporary?

    2) What would be the best way to reseal the access panel once the element is replaced? LSX or something similar?

    Thanks in advance for any contributions.

    The immersion heater will come out without removing access door.
    However is looks like an essex flange it screws into, you may loosen that when attempting to unscrew immersion heather so act with care.

    My advice would be to bite the bullet on this one, and fit a new copper cylinder in place of this, let's face it, museum piece. It's done it's time and will not be a serviceable item for very much longer. Time to say tubby byebyes. :p:p
