Hi all new to this so pse excuse,
I have a conventional indirect coil cylinder on a open vented system running off a suprima boiler.
Cylinder was leaking, cant afford new one at mo so drained down removed cylinder and repaired. Re-fitted, filled system heating coil flow and return ok, secondary stored water hot and ok, domestic hot and heating working well after bleeding but have got reverse circulation from cylinder secondary hot up the cold feed to expansion tank. Have bled feed pipe from drainoff cock, turned down cylinder and boiler stats to eliminate over heating, have bled at pump. None of which has helped. Unfortunately both domestic and heating ballcocks have gone pear shaped today so will strip try to repair or renew 2morrow. anyone got suggestions why i have got this reverse circulation and or any remedies greatly appreciated. thank you.
