Hi, Ive been having a problem with my wall mounted Bosch/Worcester 35cid boiler. It constanly needs topping up as it vents on a regular basis. It's fine when the boiler comes on to heat the water for general use only, but when the central heating kicks in the pressure goes up to and the boiler vents. This eventually leads to the boiler requiring topping up before it can be restarted, any thoughts.
