Dear All

The 3 Port Valve failed on my Central heating system which is an Valliant Eco Tec 428 Boiler with Magna Clean attached. System is a sealed system. System drained down, valve changes, inhibitor added. System re-filled but now 2 Downstairs Rads have cold cold spots in the middle and do not heat up as before. Both Rads have been bled.

Cold Spots still remain. Anyone have any ideas to resolve this situation?

Many Thanks

Caesar
