Boiler pressure Worcester Bosch highflow 400 electronic floor standing

[AjiJon]

Hi
I have just changed a leaking radiator valve, after that when I checked there is no pressure on the system. I can't find any filling loop, it's a Worcester Bosch highflow 400 electronic floor standing boiler.
Anyone please help me..

Not the right forum, but I believe whilst most Worcester boilers have the filling loop built in, this one does not. So it could be anwhere where the mains feed and the heating piping are conveniently close and will be system dependant ! You're going to have to find it. Consult the installtion manual which is downloadable from Worcester's web site for guidance.

The manual also states that the boiler can be used in a non sealed system, so check the loft for a header tank!

Thanks. But there is not a header tank. Already checked

Did you ever find out how to pressurise the system?
