Steam boiler feeding!

Ifollowinstructions

I installed a residential steam boiler 6 years ago, last year the return into the boiler rotted and leaked.  This year the sections are leaking.  The boiler is manually fed with a ball valve, is this boiler shock! I have never seen this with a gate valve for feeding a boiler.  In theory if the boiler was filled slower when hot this might never happen.  A automatic boiler feeder kicks in for 30 seconds through a small orifice so less cold water entering boiler.  The homeowner heard that a automatic feeder masks leaks! says it right on the control. Never seen any buried steam lines in a residential home and most people pass through their basements and woulds see a leak.  Good for the boiler company's.

If you use hot water to fill the boiler will the boiler company's stand by the boiler, its not mentioned in the manuals.  We are left with a $450 home owner rebate for a new steam boiler that is 6 years old.  You get a better deal with a water  heater warranty.

thermal shock does not show up as rot or rust,   usually cracks  stress related.    check the water have an analysis done.    what was wrong with the boiler you pulled out?   rotten pipes and rusted sections?

You have a leak somewhere

that boiler is taking in a lot of water. It's probably a steam leak rather than a water leak. Check the vents and the valve packings.

Chlorides

Have the water tested for chlorides, a lot of 60 year old boilers replaced by newer ones the last 10 years have leaked thru the top of the sections above the water line> If this is where it is leaking, chlorides are most likely the problem, Replacing the boiler without diagnosis will restart the problem.



Contact the boiler rep for assistance in checking this problem out.

A boiler feeder with readout will help in determining how much water the system is actually taking> check everything as stated elsewhere.  Nothing worse the replacing the boiler to have the same problem again>









I should have checked the date of this post>
