You are right

It is an LGB-10 sorry I misread the label, can you tell me where the water line for this boiler is.  Thank for any help.

Got you information

Thank you for your reply.  It is a Weil-McLain Boiler, Model # CGB-10, Series #2.  Hope this helps as we do not have the manual.  I will check the wet return lines when we have it all tore apart.

Piping on one pipe boiler

@ April 17, 2012 10:12 PM in Piping on one pipe boiler

We have a one pipe boiler system, a Parallel Flow/Up-Feed System and
have had problems getting water back to the boiler fast enough.  The
return water is piped back into the boiler at the same level as the
boiler return pipe comes out of the boiler without much of a hartford
loop only 2 inches that it comes back up to feed into the boiler.  For
the right hartford loop it should be looped and tie in two inches below
the water line as I have been reading.  Is the water line half way up
the sight glass or is it the point where the low water cuts off.  If it
is half way up the sight glass and two inches down if the boiler gets
close to low water cut off the incoming water from the hartford loop
where it ties into the header could be higher than the water level would
that matter.

Sorry.

In the lost art of Steam Heating I have been reading and trying to understand the piping for a one pipe boiler system.  In chapter 7 it shows the Hartford loop should tie into the header 2 inches below the water line.  My question is where is the water line to measure from in the boiler so I know exactly where I should tie the Hartford loop (wet return) into the header pipe(the pipe that goes from the top of the boiler and around to the bottom of the boiler where the return condensate goes back into the boiler your main supply line branches off the top of the header).  Hope this helps I am new to this and just trying my best to understand how this all works.  Thanks for you help and please let me know if you have any other questions.

TRV

I have used the TRV valves in two pipe steam system and also in the one pipe steam system.  I have the control on the wall next to the radiator and they work very well.  Controls temperatures in the individual rooms nicely.  We have a old 3 story building with several bedrooms in it.  The heating system is hot water with a thermostat on the wall and air control to the valve that should open and shut as the thermostat controls the valve with air as it need heat.  Nothing works anymore valves bad and some thermostats bad.  Can not get the valves anymore and they have been trying to control the heat by turning the boiler on and off as needed.  Some rooms stay cold and other rooms are 90 to 100degreess.  Can you use or do they make a TRV that works with hot water system that would start and stop the flow of hot water as needed.  This would be much cheaper fix and easier than having to redo the whole system. 

Thanks.

Thanks for all your help.  This is my first time on this site as I just bought books by Dan Holohan.  I have been reading them and learning a lot.  Can anyone tell me what the pH in water should be so I can get it tested.  I have turned down our pressure as they were running it at 7 to 8lbs.  I had it down to 31/2lbs, but when the boiler would start back up at about 2lbs and the blower runs for almost 2 minutes to clear out any gas in the heat chamber the pressure is down to zero.  My guess is you will tell me we have traps leaking and need to be fixed.  Have not counted but would guess we have around a 100 traps.  If this is the case could be a summertime job.

Thanks Nicholas,
We have city water and they soften it to 10 grain hardness.  Other than that I am not sure how good or bad our water is.  I was told by several people that chemical would make our systems run better and keep traps cleaner.  Also after initial use of chemical and replacing pipes that are bad now but not leaking we would not have the problem of pipes corroding and leaking.  Is this bad information that I have been told.  I run the boiler in the school with 30 classrooms, gym, and cafeteria at 5lbs of pressure.
Thanks for your help.

I am in charge of three buildings with boilers.  Two are schools and a church.  One school and the church are two pipe systems.  The other school is a one pipe system.  All piping is over 50 years old and have never had any chemical put in the system.  The boilers have been replaced and are 10 to 15 years old.  I am thinking of starting to use chemicals and clean out the old pipe and the boiler.  I know this will give us a lot of problems, but think it might be the right thing to do.  We are currently having several leaks and replacing several pipes already.  Just want some opinions if I would be crazy to start using chemicals at this time.  Wish they would have done this from the start.
