So I'm woken up to a racket coming from the water pipes, sounded like it was going to explode. It happens quite often during the summer, but then the damn thing is near-enough fine all winter. Fortunately someone else who was already up made it shut up, and I went back to sleep 
.
Solution is always to run cold water, and we've found that the tap and even better the toilet in the upstairs bathroom fixes it best.
Boiler is a traditional classic boiler (not condensing/combi), and the central heating is a sealed/pressurised system (red pressure vessel thing in the loft).
Hot water storage tank is in the downstairs airing cupboard (cold water fed, heating loop to the boiler, and 3KW immersion heater for when the boiler fails).
I know that in the loft is a cold water header tank, but others think it might have been disconnected and isn't in use since the system was pressurised about 12 years ago... I'm not sure whether it is or isn't currently in use so should probably check.
Being summer, the central heating controls are currently turned on (auto), but the room temperature is above the thermostat setpoint so it hasn't kicked in. All the radiators are turned down/off on their thermostatic radiator valves, apart from downstairs bathroom towel rail (so that if the thermostat kicks the system on or there's any residual heat, it gets directed there).
It only really started for this season yesterday, but it happens most years. In the upstairs bathroom the hot tap has always had naff pressure, and if someone downstairs is running hot water you'll probably get nowt out upstairs. If I'm trying to think about what happened yesterday that might have kicked it off, I remember that someone was trying to get hot water out upstairs whilst someone was using it downstairs, and they were moaning about not getting anything.
So... where do I start!? That hammer noise is damn annoying!
