"Help?!" My boiler seems to be falling apart, and I was wondering if I could count on anyone here to give me a (gulp) idea of how much one of these babies cost to replace if need be.......It was a horrible surprise to find just before the holidays, and before I get a service tech to my house, I found this site and thought it couldn't hurt to ask. Any takers???? I would be eternally grateful for any advice.........
