Balancing ch system

[Pauline]

Hi,
Problem is two cold radiators furthest from boiler, and the cold water inlet pipe from expansion tank to ch system gets hot and flushes into the expansion tank. Assuming the system need balancing, but don't know how. Any help appreciated.

I presume they have worked in the past. so there should be no reason they need balancing. sounds more like an air lock or blockage of some kind as you are getting a feed back into the expansion tank.
