What's this sound?

My boiler is making noises, I call it banging. I recorded it but don't think I can post a video. Is there any way to post it?

    I prefer to upload videos to youtube and then share a link here.

    It may be easier to show us pictures of the boiler, tell us the location the sound seems to be coming from and describe it the best you can.

    Please try and provide a picture of the boiler and piping from far away so we can see the big picture, so to speak.

    Have your service provider come over and check it out. Could be something simple or could nave a major disaster waiting to happen.

    I uploaded to youtube thanks for the ideaand added pictures here of the system.  it's like a bang at the start of the video. I can't tell where it comes from 😔

    @Juggatweet , is your T&P gauge working? It looks like you have no water pressure in the system. I don't know if that would cause the problem, but it is possible. It would be advisable to have your service company take a look at everything and make sure the system and safeties are all in proper working order, and to resolve the possible pressure issue and determine if there is a reason the heating system is losing pressure. The boiler is over 20 years old from looking at the nameplate (still young by Energy Kinetics standards).
    For reference, our Territory Manager for your area is Pippy Ostrow (518) 215-5126. I've made her aware of your post.
    Thank you,

    @Roger it appears the bottom half of the gauge isn't moving... would it make a difference that the heat isn't on for the season yet?

    There should be pressure in the system even when it’s not operating. Usually 12 to 25 psi for a two story home.

    Not enough water the system is breaking steam . Check the boiler feed valve....

    in your pictures,
    I think I see the makeup water feed valve turned off,
    the pressure reducing feed valve is the green fixture, all the way to the right, at about the same level as the compression tank, and air vent,
    follow that copper line up and to the left, looks like the yellow handle ball valve is off, turn that on, and watch the pressure gage go up, to 12, 15,
    if it exceeds 15, then swing that valve shut again,
    because you're at 0, you may have air in there, keep an eye on the pressure, and the pressure at or above 12,

    are the caps loose on the vents? air needs to get out,

    but wait, there's more,
    before adding water, and while system pressure is at 0,
    check your tank precharge, that air pressure should match what you want for system fill pressure, let's call it 12 psi,
    tank air pressure should be 12 before adding water to the 0.

    Ideally that expansion tank shouldn't be sidewards. That leads to tank failure. That's a great boiler. It just needs a TLC from the right person who is familiar with Energy Kinetics boilers.

    Sounds like flashing in the HX. Increase the water to a pressure of 15 psi on the blue part of the gauge.

    @neilc the tank has pressure, I turned the yellow valve... heard water coming through the pipe... the gauge works. I will check it next time it kicks on and see if I hear the banging. Thanks for your input!

    This is great, I don't hear the noise anymore and the gauge stayed in the same spot all night. Thanks for everyone's help!

    That's good news, @Juggatweet . It's important that you have a professional inspect your system as there is some reason it lost pressure originally, and there's likely a reason someone turned off the pressure reducing valve feed (also called an autofeeder). It may not be easy to find the source of the water leak, but having a professional check all of your safety functions and overall system operation is important.
