    How easy to replace a secondary heat exchanger

    Thank you, it is not blocked, it is letting water into the system and therefore the overflow is constantly running. I have had a problem with sludge and intend to flush the system at the same time as replacing heat exchanger.

    No Hot Water, overflowing overflow!!!

    Well, I dont know if I have answered my own questions, hence the post for advice. I have to wait a month where I live just for a plumber to have a look at it, so I am afraid I am still waiting in the cold for help :(

    No Hot Water, overflowing overflow!!!

    ok. looking at a diagram, I assume now it must be secondary heat exchanger that is faulty and letting water into system? Pressure is staying same. With regards to inhibitors/flush, can I put this in a new radiator before installing? How do I clear the sludge, is it a matter of taking each...

    what I meant is pipe is stiff when tap is turned on, If i turn tap off it slackens. What I wanted to know is if I disconnect the inflow pipe using one of the screws at either end, will water then leak out of either the mains inlet or the radiator inlet?

    How do I disconnect infill loop? It has a screw off fitting on each end, any end in particular to unscrew? Also if I take it off what happens to pipework, does this need a valve shutting or anything to stop it leaking? cheers

    It only started overflowing like a cpl of months ago, so I cant blame plumber for anything. Heating is fine and Rads never need b leeding (I keep checking) However there is sludge in the system probably due to oxygen getting in which I assume is same problem as overflow constantly flowing...
