Hi, my mate ask me to look a his worcester cdi30 system boiler because the pressure was showing o.5 bar. I know that is to low but how do you re-pressurise the system as there seems to be no filling loop or charge key.
There is a charge key to fill this boiler. Inst instructions contain the info as does the WB web site. Easier for you to read and learn rather than extensive typing.
