residential gas fired boiler

Pension Lover

I went down to survey the boiler room in my basement after work today . . . a daily ritual during the heating season . . . I discovered a small puddle of standing water on the floor next to the boiler. The origin of the leak that created the puddle is somewhere behind the sheet metal that surrounds the boiler.

I am new student of hydronic heating systems . . . and as long as nobody tells anybody else . . . I will admit here in this private space to being fascinated with the physics, the science, the mechanics of the whole process. I have purchased and read all of Holohan's books on the subject, but not confident in my ability to diagnose the problem.

Is it time to shop for a boiler? Mine is about 50 years old I guess (Crane Co.). The plate on the side of the boiler says: IBR rating for water: 225,100, AGA Rating input: 375,000 BTUH, output: 300,000 BTUH. It also says it is a Series 209 boiler (model 209-6).

Sharing means caring right? Anybody care to share their thoughts?

Sounds like a leak between the sections. You need to take off the covers and look around.If it is between the sections you can try tighting the draw rods.Also if you are the least bit hesitant CALL A TECH.

leak

Jim, it depends on where the leak is in relation to the boiler structure. Do you have a tankless coil? Is the leak in that vacinity? Anywhere near a safety valve? Anything overhead that may be leaking? That boiler has a lot of age to it, but we have many old Cranes still in service here.
You could test the boiler by checking the pressure gauge. Turn off the water make-up and observe the gauge (don't leave it unattented and don't forget to turn it back on). Isolate the expansion tank and watch the pressure. A drop would indicate a leak. Then you'll have to go and find it.
Good luck.
