We had a Pearless steam boiler (1991) when we bought the house in 2006. Last October the boiler was cracked and we had to replace the boiler. We applied to see if insurance could cover a the replacement seeing that the boiler was a hazard. They came and check and said... due to corrosion of the boiler it was not possible. That doesn't sound right to me. So, if the house blew up due to us turning on the boiler, they wouldn't pay?

I had to replace my furnace a few years ago. It's something that wears down and fails. Insurance usually will not cover something like this.
