Worcester Greenstar 24 Pressure Relief Valve Leak
Hi Plumbers Guild,
The pressure on this Worcester Greenstar 24 I Junior goes from 1.0 bar when the system is cold and then to 3 bar when it is hot and then the pressure relief valve starts leaking outside.
What would you advise?

Hi this sounds like a faulty expansion vessel on the boiler.
Unfortunately these are located at the rear of the boiler and you will need to take the flue off and remove the boiler from the wall.
With the age of this boiler I would recommend replacing the boiler with a new Worcester 25 kw 4000 series Combi boiler.
Good luck!
