my valve to increase the pressure is broken. pressure currently 0.5 bars. Is this gonna damage the boiler and how much is this going to cost to repair?

Hi, I have a problem with my worcester 35cdi. The hot water from tap is fine. But occasionally the pressure fall to zero when i put the radiators on. I'm fairly sure there are no leaks.

What can it be.

as a gas fitter i can tell you that worcester engineer is the road to go down i know i sounds alot but you get a corgi guy in who is not 100% clued up and he buys loads of parts untill he gets it right he will charge you a fortune because the parts are non refundable...what i can say is that it sounds like you might not have a auto by pass fitted. are you rads down low? if so leave one radiator open all the times and see how you get on with that it could be a over heat problem...

Call in a CORGI Registered Gas fitter and he will fix it for u its his job. DIY Gas work is not much fun when it fails. However as a guide could be Fan, Pcb, Sensors, Scale, Pressure Vessel, Divertor Valve, Gas suply, Gas Rate/Pressure, Water Pressure Fault finding I love it !!
