Corroded tankless coil in 20 year old Burnham

Posted by Al on August 26, 2008 at 12:10:18:

I have a 20 year old Burnham boiler with a tankless water heating coil. The bolts are very corroded and the plate has started leaking on the side. When serviced I was told that it would be cheaper to replace the boiler which seems odd to me. I was alos told that boilers typically last around 20 years which I thought was low. I thought that I would get around 30 years out of it.
In any case, I was quoted a VERY wide range of $2000-$4000 to replace the heat coil. This assumes that the bolts will break off and the holes will need to be tapped and rethreaded.
The question is this: Is it possible to successfully tap the holes if the bolts break off? Does the estimate sound reasonable for such work? Is it really better to replace the boiler?

Of course if the bolts don't break off then the work would be much cheaper but I am considering worse case scenerio.

Thanks
