Thanks bster - When cold pressure below 1 bar !!(but now when running wont go above 3 bar) seems that when i set pressure between 1 and 1.5 cold then it will go above 3 when hot. to be honest this boiler has always lost presure every year when you start using the heating again i would have to...
Hello folks - i have a glow worm compact 100 combi (9years old approx)
water presure keeps droping so top up via loop, checked for leeks found none then noticed leeking out side via presure releef pipe. also did notice when heating on presure above 3 bar
Any advice much appriciated - Cheers
