I just bought a house with forced hot water heating. It has a Burnham V7 series hot water boiler. The house is 14yrs old and I assume the boiler is original to the house.
The home inspector told me that the boiler requires yearly service so I called a company to come out. They told me that the boiler was cracked and needed to be replaced.
My question is...how can I tell if the boiler is actually cracked? It's not leaking any visible water (even a novice such as myself would take that as a hint that there was a problem!).
The contractor said he thought it was cracked before he even really looked at it? He then popped the side panel off and pointed to a discoloration on the side of the cast iron hx and said that this is where the crack is. When I asked why there was no water present (dry as a bone actually) he stated that the water is leaking out very slowly and evaporating so it is leaving behind the discoloration.
I will have to pop the panel and take a closer look myself but it looked to me like the cast iron part was in three bolt together sections and that the discoloration he was indicating was at the seem where two of the sections meet.
I want to get this taken care of if it is a problem but on the other hand this guy really seemed to be assuming the boiler needed to be replaced before he even looked at it so I'm wondering if there really is a problem at all. I've read the articles on the V7 crack problem so I guess it's possible (likely??) that it is cracked but every article/post I have been able to find, the people with the problem have said they had water coming out of the boiler through the crack, not just a discoloration??
Any help would be greatly appreciated.
