  • Coil blow out

    This is a Carrier heat coil that did not have hot water in it yet. It did not freeze and the pressure was 13 psi. There is a zone valve on the supply that was closed.
    This is the 2nd one that did this.
    What is your thoughts on why this happened.

    Looks like it was extremely overheated at the factory and the copper was compromised. Possibly made worse when the system was filled and purged as the flush pressure is usually higher.

        Ah well, then my best guess was it was too thin to handle whatever pressure was put to it.

          wouldn't want to have this in the ceiling of a computer room. Faulty copper or crap cu from China maybe.........??????????????????

          What did the manufacturer say when you returned it. If I was them I would be jumping into damage control mode immediately. Recall of batch would be high on the agenda too wouldn't you think.....?????

            Don't know if Carrier there is like Carrier here but if it is, GOOD LUCK with that. They took over one of the best heating companies around and cheapened up the product. Because they are so big they think they are untouchable. Would be good to see them get a smack or five. As a side issue there was another of their evaporative coolers caught fire on top of a roof a little over a week ago. Another product that should have been recalled for safety but they are too powerful and the regulators are too gutless.

            Oh as a thought do they have quality assurance or are they just a hack company. Do what we do, threaten to go viral with picture and comments on any blog posting possible. At worst, they threaten to sue you. Problem they have is the TRUTH is THE BEST DEFENSE.

              The Company that put it did replace the two of them at no cost. The suppler they got it from did not charge them for the two coils. The suppler is now fighting with Carrier to get there money back.
              I know if this happened when I worked in PA for an HVAC company my boss would have ate the cost and relapsed all the coils.
