Third steam boiler in 18 years
My Burnham Independence steam boiler has just corroded through after 4 years in service. I replaced two Peerless boilers prior that lasted 8 and 6 years each. When I purchased the Burnham I stated to the heating/plumbing company that this cannot happen again and they assured be that Burnham boilers rarely fail. I asked them to look into any problems I might have and all they did is replace a steam trap and fixed the slope on the main line. I had to call them back to skim the boiler the following day because the boiler was surging due to the tap oil in the system.
Clearly I have a problem but no one knows what it is. I have a 1-pipe system with 8 radiators, northwest of Boston, town water.
I keep all the steam vents clean and new. I add about a gallon every 2-3 weeks in Jan-Feb when the boiler is cold. I flush the cutoff valve frequently removing about a quart of water and fire the boiler up immediately to remove the oxygen. The rusty sludge is removed when I see it in the glass.
Thought? I cannot continue to replace boilers at $6000 each every few years.
