BANGING BOILER

UBHAPPYUBHAPPY Member Posts: 1
The boiler bangs. Our heating contractor blames it on contamination in the water/glycol.

Can this be the cause? We have a seperator now he has recently installed a sock filter. Claims this will filter out the fine contaminants. I have a high efficiency Lochinvar Boiler. Claims the piping in the boiler is very narrow. No help as yet. Can this be the cause of the banging or could it be air in the system?

    Head Bangers:

    What's the anti-freeze solution? It shouldn't be more than 1/3 glycol, 2/3 water. It gets too thick and the pump(s) can't push it fast enough.

    What's the boiler system pressure? If it has sediment in the boiler, it needs to be flushed out. Sediment gathered in low spots in the HX can cause your problem but I think it is more complicated that what some may think.

    Have you ever had your potable water tested? What are the results? What else can you tell us about the system?
