Hi
I have a Vaillant Turbo Max (824e) boiler and pressure is normally around 1-1.5. I woke up this morning though and radiators were pumping out more heat than I have ever known although 'daytime thermostat setting' meant that they shouldn't have been on; pressure was climbing to 3 bar. I then turned boiler off for a while to allow pressure to decrease and when I switched back on pressure valve continued to climb again....
I have now switched radiators off and just kept hot water on and that seems to have bought the pressure back down to normal.
Any idea whats causing this?
Thanks for your help
