Dunkirk steam boiler problem

I had a dunkirk boiler installed less than 2 1/2 years ago. It turns out the boiler has a hole in it above the water line causing water loss out the chimney. What would cause the hole to form in such a short time. The boiler parts are covered under warranty but I'll have to pay for labor, what a ripoff. Also, what can I do to prevent this from happening again.?


  • a couple things

    Have a water meter installed on the feed pipe to the boiler, and avoid high amounts of fresh water.

    Have your water quality and pH tested by someplace like Rhomar Water. Follow their guidelines.

    Maintain your water quality often enough that it stays in good condition.

    There is only one thing that can cause this, Kevin,

    and that's too much fresh water. Do you have a water meter on the feed line? There's a leak somewhere in your system. Hydrolevel has an automatic feeder that tracks the amount of water entering the system.

    There's not a steam boiler in the world that can last long under these circumstances, and while upsetting, I don't think you're being ripped-off.
    Retired and loving it.
