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

Give a G200  serious look, 409 stainless to avoid those rust thru problems and a company that strives to keep its customers happy.

this may sound dumb,but my dads cousin lives in coldbrook n.h.
i think his is a central and its about 6 years old and it had to be shipped away twice to be welded because
of leaks.one day we were talking at the shop and i mentioned that i repaired mine once with
that j.d weld  putty.you know the one in a stick you break a piece off and squeeze together .
anyhow it worked for mean i told him to give it a try.
you don`t need to empty the boiler.just clean around the hole and voila.
was costing him a fortune in shipping charges and if he welded it himself it voided the warranty

You know, I never even gave the J.B.Weld stuff a thought.  What the heck, I think I'll give it a try seeing the problem is around the air channel.  Thanks for the tip.

I have cousins who live in Colebrook, N.H. also.  It's been years since I last visited them.  My brothers and I used to go up every year for the blessing of the motorcycles at the Shrine on Rte 3.  It's too bad it closed it's doors.  It was a beautiful place to visit.  Roger

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.

i did a bit of research.muffler and exhaust sealant is rated at 700`f.may not be great in direct fire
but may work in non direct parts as a quick temp fix.
perma tex is one type.j.b weld also makes this.
my fix with j.b stick weld was not in direct fire but was exposed to some heat

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.

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...

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...

They have been making furnaces since the mid 1980's according to their website.  Mine was manufactured in 1996, I cant complain about it's longevity.

[dukethebeagle]

i bet you put epoxy on it and when its dry put a bit of stove cement on it,it would work

Neighbor has a CB that’s two years older than the homemade I built in 2000, so his is a 1998 and he’s still using it. He’s not sure how much life is left in it, but he’s gonna use it this winter.

[GCTerpfan]

Yeah, I am not sure how much life is left in mine. I am going to use it until I can't, but I have been eyeing up those G series units lately.
