@ July 29, 2014 6:41 AM in Burnham IN4 steam boiler pipingThe risers coming off the boiler may also have been reduced in diameter to a size too small. With the present arrangement, the steam and water exiting the boiler are being unsuccessfully forced to go in opposite directions, which they will not do.
Contact your local Burnham rep, and see if they will honor the warranty with the boiler piped in this way. What sort of warranty was offered by the installer on his contract?
You probably will have an unstable waterline, which puts abnormal thermal stress on the sections of the boiler. Was the boiler ever cleaned (skimmed), following the install? Draining and refilling 20 times does not count.--NBC
@ July 28, 2014 11:27 PM in Near boiler piping issue?Besides the possibility of an improper piping issue, there is always the chemistry contractor. Would he ever say that it is not fine? The best additive to our heating boilers is H2O, unless there is some clear water problem which needs a Ph adjustment.
Drain off some of the boiler water in to a pan, and place it on the stove. It may behave like a pot with potatoes, covered and boiling too fast. The resulting overflow, will swiftly empty the pot of water, and dry out the potatoes, just as it can empty the boiler.
What is the steam being used for-process, or heating purposes?--NBC
@ July 24, 2014 5:49 AM in Cemetery chapel improvementsThe existing system is a Dunham vapor, with a leaking, mis-piped Bryant (Dunkirk?) boiler. I may even do a little vacuumizing with it.
Interesting that you mention Cleveland, because there is the beautiful Wade chapel there. Someone from Cleveland was telling me how beautiful it was, and then when he saw our chapel; said ours is more beautiful!
As this is a part time project, we have been first stopping all the leaks into the basement and crypt, and completing other deferred maintenance, before replacing the boiler.
A City-Multi Mitsubishi could handle the cooling.
Like any historic project, you make a list at the beginning, and as you cross off some jobs at the top, you discover more jobs popping up on the bottom!--NBC
@ July 23, 2014 2:19 PM in Cemetery chapel improvementsThe steam rejuvenation is still on hold, but hopefully will get to a couple of ounces this winter.

@ July 20, 2014 4:47 PM in Advice needed on heating system installwhy is it you are rejecting steam? when steam systems were being regularly installed, they were sometimes regarded as superior to gravity hot water, because of their efficiency. those old systems were quiet, even, and economical.--NBC
@ July 15, 2014 7:23 AM in Steam heat and Programmable Thermostats, good idea?Why not start a new thread for your question in the steam section, stating the type of system you have, what you wish to do, and any symptoms you encounter.
We really don't know if you have resistance heat, or steam, and is it a barn or an old hotel?--NBC
@ July 15, 2014 7:19 AM in How LongCan you put a funnel on one side, and then fill the pipe with a 5 gallon bucket, to find its volume?
Then it should be a simple matter to determine its length.
Figuring out its depth underground before it enters the lake, would prevent freeze ups in winter as well.--NBC

@ July 9, 2014 10:58 AM in What do you think of this new product?Unlike English toilets, our domestic varieties have a separate passage (I believe) up to the ball-cock in the tank, which allows the trap to fill after a flush.
I am sure this will prevent any pressure from being applied to the blockage. Most of the time it is the suction stroke which pulls the debris up enough to loosen it.
This device follows the arrangement of a well-known English practical joke, wherein some clear plastic sandwich wrap is stretched across the porcelain bowl. The next user is in for an unpleasant surprise.--NBC
@ July 9, 2014 7:56 AM in Old Vaillant boiler info neededRemember to follow the proper procedures for sizing the replacement water/steam boiler, and not merely go off the old specifications!--NBC
@ July 5, 2014 5:44 AM in Can this boiler leak be fixed? (homeowner w/ pictures)Replacement is the lowest hanging fruit you will find in this. The new boiler, whether it be cast iron, or mod con must be chosen for its ability to keep up with the heat loss of the building, so use the SlantFin software to calculate that.
Use the find a contractor button here to find an expert in your state, and compare his heat loss calculation with your own. Check his references for such installations.
Do a search here for gravity systems, and read the various post on the adaption of new boilers to old systems. Many manufacturers will provide recommended piping diagrams for gravity system installation.
We do not discuss pricing here as the costs vary state by state.--NBC
@ July 3, 2014 10:16 AM in Replace the header or supply it.It would be wise to do a survey of the radiators to check on the sizing of the new boiler, since the old one may have been incorrect.
The manufacturer's piping instructions should be followed at a minimum. A drop header will solve many problems of installing and running, especially with a large header, and both risers being used.
If there are 2 mains, then pipe a separate takeoff from the header for each.
Pictures of the current setup would be very helpful.--NBC
I think I now understand your exact question, so let's definitely see some pictures.
@ July 3, 2014 5:23 AM in Dan's newsletterThis article seems to have some logical black holes
It seems to recognize the benefits of radiant heating, but uses the less efficient (and green) form of electric radiant, compensating for that by trying to direct the radiant towards the occupants.
I think it a fallacy to blame energy waste on heating momentarily unoccupied spaces, when the real culprit is heating badly insulated spaces.--NBC
@ July 2, 2014 11:21 AM in New gas boiler sizingHave a look at the Lochinvar Solution, which has an outdoor reset option (may not be useful with your amount of baseboards).
It is a lightweight copper heat exchanger, 2-stage gas valve atmospheric, which will not break the bank, or your back carrying it downstairs.--NBC
@ July 1, 2014 9:28 AM in New gas boiler sizingWhat about putting a new gas burner in the present boiler. That would surely cost less than a new mod con, and you would be warm. When the boiler dies, then a new boiler could use the replacement gas burner.
Any piping problems should be corrected at this time.--NBC
@ July 1, 2014 9:20 AM in One Pipe Steam - What Is This?I would be afraid of making any penetrations in the roof to vent the trap exit, because the exit might become blocked with ice in the winter, and the hole might leak. Could you drop a pipe down the same pipe chase? Pex could be used here.
Alternatively, the venting could be increased on the dry returns so as to have capacity for the riser as well. Just keep the amount of venting on each dry return the same so each has the same resistance to the escaping air (as low as possible). Otherwise, you may have one return getting steam more quickly than its neighbors, leading to unbalanced heat. A 0-3 psi gauge will show you how close to the open pipe equivalent you are. With that size riser, you may need some big traps. Look in the venting guide available in the shop here for their capacities.
Remember, " air is the enemy-to be chased out like the raccoon from the garbage can".--NBC
@ June 30, 2014 1:58 PM in One Pipe Steam - What Is This?I tried to search for the thread showing that modification, but haven't found it yet.
I think Dave QCA, and others have done this, saving space, and gaining capacity, using a Monash trap.--NBC
Here it is:
@ June 30, 2014 10:52 AM in One Pipe Steam - What Is This?Probably the maintenance crew have been raising the pressure to compensate for inadequate main venting.
The existing vents could be replaced with some traps as others have done. Perhaps a trap at the top of the main riser would speed things up.--NBC
@ June 26, 2014 4:10 AM in Combine two heating zones into one, any savings?Did you ever notice, when the thermostats were set differently, that the boiler short-cycled when heating just one zone? These boilers work best when they fire for longer instead of shorter periods of time. If your boiler was correctly sized, then it will run on low fire for extended periods of time, just keeping up with the heat-loss on a milder winter day.
If it was oversized, then it will short-cycle, when heating only one zone, which is less efficient.--NBC
@ June 25, 2014 7:30 PM in boiler ventingGive some thought to protecting the boiler from freezing, while there is no call for heat.--NBC
@ June 24, 2014 4:09 PM in New Geo System vs. Old Steam System Systemfrom the radiator pictures in the other thread, it appears you may have a vapor/vacuum system [what name is on the traps-Dunham?]. these were very high quality systems for their day, and still run well, sometimes at 2 ounce down to subatmospheric pressures.
as far as age of pipes verses leaking, my pipes are from 1885 [not the oldest here], and I have had very few leaks.
I suspect that Jamie is right about failed traps, and high pressure, causing your high fuel use, which are easily put right. I suspect the boiler may have a 2 stage gas valve which would also reduce the cost of running if functioning.
post some pictures of the boiler, controls, and piping, and lets see what other suggestions we may have, to reduce your consumption by 50%..--NBC
@ June 24, 2014 7:18 AM in Need help rating these radiators.Good point to make SWEI, that heating with electricity is less Green (and more expensive) than heating with gas, in terms of carbon footprint.
Let's have some pictures of the fan-coil unite, and of the boiler, and maybe we can get your heating bills reduced with a few relatively simple alterations.
The desire for fuel economy is nothing new, and when your church was first built, steam was chosen for its economy, and comfort. Over the years, various repairs, and modifications, made by well-meaning, but unqualified people have made the system perform poorly, struggling to do its job, and burning extra fuel as a result.
What handles the air conditioning now?--NBC
