    The pump should not stay on without demand. It sounds like overheating. Could be lack of flow (faulty pump) or scaling. Probably also a lot of dirt in the system which would require a powerflush. Open vent systems like the one you have are really quite outdated. To get rid of your problems once and for all, the best thing to do is to upgrade your system to a sealed and pressurised system like Worcester or Vaillant and have the works done by a known, local company. Added benefit is that you can drink the water from every tap in the house without the danger or unacceptable levels of bacteria in summer.

    I'm not sure if my problem is related:

    I rent a place in Bath, a high limescale area. I'm not sure if that is relevant.

    Our heating works fine, most of the time, apart from exorbitant gas bills despite the fact we have the heating on very rarely (as I type this I have three jumpers on, as usual in this damned fridge of a house). This isn't the immediate problem, although it would interesting to know if a technical fault could somehow boost our gas usage.

    We have a Baxi Solo 40PF. The "Overheat" light won't turn off, no matter how long we leave the boiler either switched off at the mains or set to zero. The boiler doesn't even attempt to heat up, though, when we set the dial to a non-zero number, so how can it be overheating? It's probably about 15 degrees in there!

    Thanks if you can give any information.
