    ...then he should be experiencing "pitching" through the expansion pipe if the pump is too strong. But there has been no mention of that symptom from him.

    Is that not what he has been talking about since the beginning?

    I'll check tomorrow how pump is fitted. So far I notice that water goes to tank small tank thru this pipe with yellow arrow. Water is warm in that small attic tank. Also I could hear some kind of banging from time not sure from where.
    I have it same problem before pump was replaced that noise and water overflow so plumber told me that's my old pump not going strong enough.

    Ok, just to be clear, the water goes up through that pipe, that pipe hangs over the top of the small tank, and water is dripping or pouring out of it and into the tank?

    If that,s the vent pipe then there should be no gate valve in the hot feed to the cylinder as the vent continues on up from there and should be completely unrestricted.

    I got the impression that the tank was filling with warm water, but through the tank feed pipe rather than the expansion, giving suspicion to a possible leak on the coil.

    Spotted that as well, I wonder what else might be wrong with the pipework :rolleyes:

    I just presume going on his description and first pic that it was pitching.

    Also tomorrow, see whether the pump is installed on the return to the boiler with arrow pointing into the boiler OR is installed on the flow from the boiler with the arrow pointing away from the boiler. Also if you can see where the cold feed is connected into the system.

    That how it looks and then goes thru overflow pipe when level is too high. Now after a good while when heating is off i could hear that weird sound like water dripping and hitting the cealing or something and that spund goes for good while.
    Guys could that dripping shower mixer can cause any of that like cold water get mix with hot etc
    Those 3 pipes from cylinder are hot is that how should be ?

    Out of curiosity, turn the red valve a full half rotation anti clockwise and see if that makes any difference to things.
    Also, are all of your radiators heating up properly and does this happen while they are they all On.

    Red valve is fully open can't turn it more anti clockwise. All radiators are very hot no problem with them or air in them. If you ask about that sound it happens even sometimes when I use the bath and after I turn off hot water tap.

    Can you change the pump to UFH mode.

    That happens because of the pitching I'm presuming?

    Arrow at pump is pointing down.

    Pump is correct, on the boiler flow, pumping away from it.

    You might note the pump power on speed 1 before you change to UFH mode and then note it again in this mode.

    If pitching ceases and if the rise in the tank level doesn't reach the overflow then you can probably live with it even though not ideal, you might also note if the level rises as soon as the pump starts up of if it rises after the system heats up.
    Also see where cold feed tees into the system.
