    BIG BANG - FROM HOT WATER PIPES

    A new heating system was installed in my duplex.

    Our main floor has a hot water 20 Kw Electric Hydra boiler and our second floor is only electric baseboards.


    We originally had hot water oil furnace.

    The problem is from our main floor with the hot water electric boiler. Every time it turns on there's this loud bang that comes from the pipes of the baseboards.

    What can be the problem? Is this safe? We already called the technician.

    You'll need the tech to find out what it is for sure.
    Looks like 2-¾" return lines, and 1-¾" supply.
    That can give you some hammer noise.

    How many times must one fix something before it is fixed?

    Been, how'd you see those attachements? All I see is an empty box that says there's attachments but nothing in it.
    If YOU want change, YOU have to first change.

    If you are waiting for the 'other guy' to change first, just remember, you're the 'other guy's' other guy. To continue to expect real change when you keep acting the same way as always, is folly. Won't happen. Real change will only happen when a majority of the people change the way they vote!

    Sounds like water hammer, nothing compared to a 6" water line form a fire hydrant busting, LOL !!! We used to do that once a month without fail here in town. Villiage guys didn't like us to much

    Big bang from hot water pipes

    Just got alook at the first picture never could get the second one to load anyway back to your problem looks like you have aexpansion tank need to know if the cir. pump runs all time if not the hot water will hit the cold pipes causing them to expand guess what something got to give end results is alound bang.

    its hard to tell from the pic but it looks like you have 2 way valves. they take a while to open so if your pump comes on instantly it will cause hammer

    Usually, I'm the one that can't see them.

    Thanks for ur help. I have re-posted the images and added 2 more pics.

    I appreciate the help and will give the info to the technician if he ever bothers 2 show.

    I have to tell you that this is just not a bang but sounds more like one big explosion every time the heat turns on.

    the main floor has an upstairs and a downstairs if that matters.
