My recently acquired two story flat came with a Glow worm 24ci combination boiler which keeps losing water pressure daily. Sometimes I cannot even get the pressure upto 0.5 bar. I called a boiler man who said that I should either replace the expansion vessel (recently recharged by him) or replace the whole boiler, which seems a bit drastic as it is only two years old. There are no apparent leaks on the system and the overflow pipe sometimes not always discharges water.
Can anyone help?
