The pressure on my Baxi combi 105e instant is 1 bar when idle and rises to 1.8 bar when CH is on. With the CH off and hot water running (including preheating) the pressure drops to around 0.6 bar.
Would appreciate thoughts on why the pressure is dropping so low.
Have just fitted a new expansion vessel as the old one was leaking internally.
Thanks
