Our central heating system loses pressure in a dramatic way (gauge is down to zero within 2 weeks of topping up the system). This has been going on for several months. We've looked at all the radiators and at the wall/floor around the boiler, and re-checked an underfloor pipe that was mended a few years ago, and there are no obvious water leaks that we can see. Also, our downstairs neighbours know about this but haven't reported any damp on their ceilings (yet!).
The boiler is a Vokera Mynute, 9 years old. Nothing plumbing-related has been changed in our house to explain the problem starting. Even at very low pressure, the central heating system works correctly. It doesn't seem possible that we could have a water leak going on for months at a stretch without our neighbours finding water patches. Can anyone suggest anything?
