  1. Temporary repair of heat exchanger - JB Weld ?

    We have a gas pack that has a estrus exchanger with a spot that is rusting - about the size of dime - and at the eye is a small-scale pin tip area that looks about fix to requite way. Nosotros want to exercise a temporary prepare for a few months until atmospheric condition warms upwards and contractors are less decorated. No elevated carbon dioxide levels in abode - but a gassy smell at the unit exhaust. Was told this means the exchanger is on it's last legs and other causes were ruled out.

    Would JB Weld agree up to the oestrus of the exchanger - or some other product? Trane ii ton gas pack dated 1999. Used to encounter commercials for something chosen "Allumaloy" - but call back that requires welding.

  2. BAD idea, if y'all do this it volition put the lives of anyone in the habitation at hazard!

    If you knew y'all wouldn't ask that type of question.
  6. Typical this time of year when the gaspac'due south run a long bike and the Truth comes along.
    There is no 'fixing' of a bad HX exterior of replacement of it or the unit.
    Period,Stop,Cease of discussion.
    We let it run,You die,Hospital,Lawyer's,
    Story never cease'due south well for Everyone.
    Y'all,Should have Whatsoever 'Gas Heating Unit' checked annually BEFORE it become's Cold and You are 'Without,'When.
  7. Time to lock this one upwards.

  8. Why?
    These are Factory designed,formed,welded 'pieces' which Nosotros are NOT 'allowed' to gear up.
    L-I-A-B-I-L-I-T-Y.......
    Nosotros 'try' to repair them,
    Nosotros Assume the liability of Your LIFE. And we are not GOD.
    10-4.
  9. Replace the HX, or unit now. Waiting just increases the chances of health problems.
  10. A crack or small hole is a FAILED HEAT EXCHANGER. None of us can tell you it's ok to patch it. We can tell you it'south a failed function and needs to be replaced. Either the heat exchanger or the furnace. No getting around it. If your fan motor failed and you asked if y'all could put a paw crank on information technology and manually spin it for a few months I'm certain people would say, "Sure go ahead, the furnace has limit controls to protect against over temping" just the furnace has no protection for carbon monoxide leakage (non carbon dioxide). The merely protection is a sound heat exchanger, that's it'due south task, if it'due south bankrupt information technology tin't do it's chore.

    I didn't write the book I only read it!

  11. I appreciate folks in the trade not wanting to set a heat exchanger for liability purposes. But that'south not what I asked and wanted to know if some grade of temporary patch can be practical.

    If there is no CO2 upshot at present - what is the problem ?

    I am just request because I am a homeowner and the "just buy a new one" doesn't fit into our budget right at present. Accept to believe this is a common problem out there.

  12. You take been given more than information than virtually DIY questions become, the issue is you are not taking it. Go your budget in order and get a new heat exchanger or complete unit. I retrieve that is all you will become here.

    I am just asking because I am a homeowner and the "just buy a new one" doesn't fit into our budget correct now. Have to believe this is a common problem out in that location.

    The "folks in the trade" are experts. The answer from the experts is an emphatic No. At that place is no temporary fix. You run a risk the prophylactic of all in the house if yous try some cockamamie repair. To repeat an earlier correction, CO2 is non a concern. CO is a very real business.
    I promise that is clear plenty for yous.

  15. You land you accept no elevated CO2 in the habitation...

    The result has NOTHING TO DO WITH CO2...

    The event is with the Blood POISIONING Chemic CO WHICH IS CARBON MONOXIDE... the hole does two things, it alters the oxygen mix feeding the flame resulting in a high CO production, and the hole allows the concentrated mix of the chemical into the home.

    NO. NO. NO. YOU CANNOT SAFELY REPAIR THE HOLE...

    Yous MUST REPLACE THE HEAT EXCHANGER OR THE FURNACE, OR ENDANGER YOURSELF, AND YOUR Family.

    Period!

    How do you know there'south no CO leakage considering the detectors oasis't gone off? Dwelling house detectors trip at to high a setting. 50PPM or higher all the same low levels are dangerous.

    Get the unit repaired or replaced. Your life depends on information technology

  17. Folks that have estrus exchanger failure and tin can't afford to repair or supersede it at the fourth dimension accept few options. Offset option is finish the season with space heaters. 2d option is utilize for state or local assistance. Financing is a 3rd choice only that one might require working a second task .
  18. Cracked or compromised estrus exchanger presents a burn and CO run a risk. Hacking "temporary" repairs elevates those risks and could even drag them.
    Afterward you slap a pile of goo on the old exchanger what do yous remember will happen to the hot spot you only created?
    There is no "cheap" way effectually information technology. Doing something similar you ask is incredibly stupid and puts your family'southward lives in danger and puts your dwelling house at risk of fire.
    Why not telephone call the makers of JB and inquire them if their product is rated for gas fired heat exchangers? Encounter what they have to say.

  21. Basically isn't JB weld just plastic? Doesn't plastic melt and or cause toxic fumes?
    In that location is NO rubber fashion to practise what you want. There is no one on this forum who would recommend any kind of unsafe fix. This is the best answer we could give you.
