Oil Furnace boiler leaking water? Repair or replace?

Hi and thanks to those who read and respond to my post.





I think the oil furnace boiler is leaking water internally. I did my spring furnace clean, and found the soot in the bottom of the boiler inside was moist. Before, inside was VERY dry and easy to vacuum. Soot does not smell like fuel oil. The concrete pad around it and the water heater is damp, but not wet. (Gas Water heater just replaced and problem remained). There is also evidence of water in the flue pipe, with dried rust stains on outside of pipe. The furnace was very noisy this season at shutoff.





Is this a leaking boiler, or could it be something else? Is is repairable, or time to replace? The hot water unit (Vaillant) is about 20 years old. The Igniter unit (Blue Angel) is about the same age.

At 20 years old I think it would be wise to replace it with a more modern unit , I just went through the same with mine once they start leaking then some other part goes,it doesn't run as smooth or efficient as it used to etc. If you can't afford getting a new one or want another opinion ask your service people to evaluate it for no charge.Oil Furnace boiler leaking water?

Did you check your chimney to see that the rain cap was still on? Maybe that is where the water is coming from.
yeah,sounds like its from outside. the water is under pressure and if it cracked,ud have lots of it
