Hi, I have Worcester bosch 30cdi condenser boiler that is loosing pressure pretty quickly, I would say over 24 - 48 hours from 1.5 bar to 0. When topping up it takes around five minutes so we are talking a significant amount of water loss.
I have checked all the piping apart from around 12 ft that I can't get too, what I have also done is isolate the flow and return pipes beneath the boiler to the radiators, and over a period of around 8 hours it lost 0.5 bar pressure. Would I be right in thinking this is defintaley a problem with the boiler and not the pipework???? If so any ideas on what could be??
