Boiler switched off for months but still delivers warm water

Hi,
My 30 year old Potterton Kingfisher is switched off at the controller but I still get enough tepid water for a daily shower. This has been puzzling me and I wondered if anyone could suggest a possible cause.

    Most likely a stuck zone valve which is allowing some hot water through.

    Is the pilot light still on?

    Ours is down to our pilot light being on all the time. We can actually have a reasonable bath out of ours without switching the heater on at all.
    make the most of it, we are only here for the weekend.
    and we will never, ever return.

    Is your cold tank in a very hot loft?

    Two very relevant questions by G4Y and Mac. Also I'd like to ask if its a gravity DHW configuration?

    My guess is pilot light, gravity circs, and well insulated cylinder.

    Thanks for the replies,it is an old gravity system. I didn't realise that the pilot light could produce so much heat.
