In the house I purchased a couple years ago I have an old hydronic heating system with 3 zones.
Last winter and this winter I've started to hear a big "BANG" from the boiler. The noise carries through the pipes and can actually 'startle' you because it's so loud.
It didn't do it much when I first turned the boiler on this winter, but now it's doing it more and more.
Also, from a timing standpoint...it seems to make the noise after the boiler or pump or heat "shut's off". I know it's not happening when the thermostat is turning on...it's more after it's turning off.
I'm ready to call the local plumber, but I'd like a verification of what he may tell me.
Does anyone know what could be causing this big bang?
