Central Boiler / Re: Questions
« on: December 20, 2016, 08:47:22 AM »
sounds like a lack of water getting to the exchanger. flow, air lock, pump size, head loss all could be a factor
What size pipe are you running from the stove to the exchange? Also - what is your elevation difference from A to B. As RSI said you may need a bigger pump, if your pipe can handle the volume.
also - did this ever work in the past? if so what changed? (ie, added a loop/zone, etc...)

Central Boiler / Re: M250
« on: November 22, 2016, 09:41:34 AM »I have a 200 bushel bulk bin and auger system on order, and will be installing that soon. I have been working on an Arduino based controller/monitor for the bulk bin feeding into the M250 hopper. I will also be monitoring the status of the furnace, things such as feed auger, blower motor, water temps, burn chamber temp, snap disk status, ect.
Ardunio, I love it!
Keep us posted how it goes, always been interested in doing something like this.

You should be good if it's still holding. I had almost the same issues last winter. My CB started leaking on the inside of the firebox. My brother in law is a pretty good welder but, we had many of the same problems you describe in getting a weld that didn't leak. My brother in law was embarrassed of the final product, it wasn't pretty but, it is still holding. I know that I didn't sleep for many nights wondering if it was going to start leaking again.
I can't complain though. This furnace is over 20 yrs old now and is still going strong.
Thanks for the vote of confidence!
My welder was feeling the same, looks like a high school kid with a stick welder did the job.
but if it works, it works.
20 year old CB? Didnt know they made them for that long...

« on: October 26, 2016, 09:20:54 AM »If its just the water jacket and NOT exposed to flame, Versachem makes a epoxy specifically for repairing radiators. Takes heat very well and I’ve used it in the past on radiator reservoirs and even a few oil tanks. Its the same company that I use their fuel tank repair product on diesel tanks on our trucks until I get enough spare time to remove the tank, steam clean it and weld a proper patch on.thanks, unfortunately its on the inside (fire side) of the water jacket where were welding. no access to the back side without major demo to the shell and exterior of the water jacket.
day 3 and its all good - so far...

So we have completed welding - welder ended up needing to get very creative on a patch but hes done and ready for testing.
Fired up the boiler last night and all is good. up to temp and no leaks, yet...
sure is nice to be back online for the time being. fingers crossed.

anyhow it worked for mean i told him to give it a try.
thanks for the thought, this has passed my mind, but my concern is in Feb when its 10 below and the JB fails... however I may be trying anything at this point.

Thanks Slim, going to be at the Hopkinton Fair this weekend, demo derby!!
Interested in learning more about the G200 though.
thanks for the offer to get me in the gate!

General Outdoor Furnace Discussion / Looking for a new boiler - replace CB2400
« on: September 01, 2016, 09:07:55 AM »
Hey All,
I currently have a Central Boiler 2400, which has developed a leak in the water jacket.
Several attempts from a welder to fix have not been successful. The water jacket is paper thin which is an absolute design flaw that CB knows of but will do nothing for me as Im the 2nd owner. The unit is 8 years old, they have a 25 yr warranty - to the original owner. I understand it is what it is, however they basically laughed at me when I called... and said, here is what others have done. So its a known issue and they can hide behind the language in their warranty rather then doing whats best for their customers. I was looking for them to work with me, not replace the unit. I asked what if I traded up? laughed, we dont have a program... so CB is now in my rear view window and I need to find a replacement. Rant Over.
I live in Central NH, heat an 1800sqft home and DHW and need to plan for a future 800-1000 sqft garage.
Burn seasoned hard wood, minimal pine.
Im looking for some input on units that have been proven and if there has been an issue the manufacture is willing to work with you on a fix.
thanks for any input
and if anyone is looking for a CB2400 project boiler, let me know as its likly headed to the scrap yard.

continuing to work on the patch. 2nd attempt has failed. the water jacket keeps splitting at the weld because its such thin crapty metal.
Welder has 1 more idea of a patch, next option is to plate the entire side of the water jacket with something thicker then the tin foil Central thought would be a good idea
Im only 500 into the "fix", wtf right??
Honestly, not sure im comfortable at this point, having an issue pop up in Feb will put me over the edge.
Im ready to crap can this thing and buy anything but a CB, time is ticking so I need to do something within the month....
Folks local to NH, what options for boilers are out there? 1800k sqft house and a future garage is what I heat.
100% wood

Update on the situation.
Had a welder come by to see what he could do
we cut out the leak (4"x4" area) to make sure we got it all.
We were both surprised on how thin the water jacket was (he felt it was 20ga).
upon attempting to weld a patch in, he was unsuccessful largely do to the patch was too thick and the existing water jacket too thin.
He needed to get new stock and a Mig to finish the job.
I feel like this is only the beginning - ugh

« on: March 22, 2016, 07:35:54 AM »15k into the OWB and we need to have a welder on standby... pricelessCorneroffice - I hope that's all I ever need from the welder, just standby for the "just in case" scenario. Oh, that reminds me; test the water to be sure the treatment is up to snuff.
So I get home last night and I hear a beep beep coming from the boiler... o no... the display is showing 000, o no, low water. The boiler has been running well for my second season (I got it used, its a 2008). So I check the sight class and sure enough its low. I check the basement first for a blown pipe, nothing, inspect around the boiler and it all looks good... but im thinking this is not good... I decide to fill the boiler to see if I can see whats going on. With the fire box door open I see a strange build up of creosote on the right wall about 3/4 the way up. I scrape a bit of it away and instantly a pin hole of water is shooting into the firebox. I then scrape a bit around it to see how bad this is and another hole opens up. Continue to clean around the area and no more holes but the area the size of a 1/2 dollar is very soft to the touch. I bet a soft tap of the hammer would go right through.
I have never had to add water, the PH and nitrate tests are right on the money.
Im sure based on what I have read on this site that CB is not going to give me any love, Im not the original owner (although the unit is only 8 years old) and I have had to do a slight mod to the air channels as they were riddled with cracks and not working any longer. I do have a call into them, so fingers crossed.
Plan B is what Im planning for now.
1 - looks like folks have success patching the infected areas. I have a few good friends that weld so I have access to that.
Also sounds like if Im going to patch this area I should clean and thoroughly inspect the entire jacket to ensure there are no additional weak spots developing.
2 - Dump the CB and look for a new one...
IF there is a silver lining in any of this, its the end of the season and I was planning on a shut down in a few weeks.
Thanks in advance for any suggestions or comments.
Jody

After modifying my air channels on my e-2300, adding a flow check to my manifold, expanding my radiant zone, and stacking 11 cords of nice dry hardwood in the shed... I will be touching mine off this weekend. cant wait for a heated garage, unlimited DHW and a silent heating system!
My wife was skeptical of the OWB when I first installed it, however she has come around and has asked several times over the past 2 weeks "when we firing up the boiler?" gotta love it!

Hey Randy, I have a similar issue going with my 2400 and was wondering how you made out with CB and the replacement kit?
Thanks!
