Hot water in Header Tank

Post  Nolly on Wed Nov 21, 2012 6:34 am

Hi'
I have a situation where water is trickling into the header tank via the small hole from the main tank which I presume is meant to work the other way around and keep the main tank full!
The header tank has a ball valve to keep it topped up to the ridge marker, but the hot water keeps entering the header until it of course exits via the overflow (luckily there was an overflow pipe fitted!).

Does this mean that the coil is damaged and is presurizing the tank?
Does that mean a new tank?
Best Regards,
Paul.

I would say yes, depending on the Pulsacoil you have, if yours is a 2000 , means a new exchanger needet to be fit, this will mend your problem, if yours is a Pulsacoil 3 or before, yes you need a new boiler

Many thanks for advice Mario.
Not sure what model it is as it's not in my property (it's at my daughters flat), but everything seems to be enclosed within the main cylinder.
i.e. there are no valves etc. on the outside) with just a 22mm cold mains feed and 22mm hot exit pipe with a flow regulator.
I suspect a new boiler is needed!
Best Regards,
Paul.
