I will try to borrow a camera and post a picture or two.

money spent

@ July 23, 2014 8:45 PM in Suggestions wanted

Personally I don't think that I would have dropped all the big coin on this outdoor woodstove and related piping. The home owner is a good friend and I got involved after everything was in place. I do not have any electrical  wires that can communicate between the two boilers. I found out today that the boiler had two 1-1/4" tapping's. I spent a lot of time manifolding the 3/4" tapping's together. But I would have had to drain 400 + gallons of water with expensive additives. So, I guess it was justified.
I read the directions today for the first time. The wood boiler people do not want the return temperature to fall below 150° F for extended periods . So I think the 0014 @ 6.6 gpm isn't such a bad thing. It came with the boiler incase you used a shell and tube heat exchanger. Those little pumps are $$$. If I do outdoor reset I won't need high temperatures most of the season and I won't get the huge system dump load when the t-stat calls.

I would have spent all that money on insulation , windows and doors, a good boiler , out door reset , and an indirect water heater.

Prim/sec piping

@ July 23, 2014 6:09 AM in Suggestions wanted

One of my biggest obstacles and the reason I am looking for help is the piping arrangement. I can not seem to get my head around how I can tie it together. My Imagineering skills are not working well on this one. The piping leaves the boiler in two directions . Two supply and two return. The supply main decreases in size toward the end of the main. The last radiator( both sides of house ) is the end of the supply and also the beginning of the return.
In my first post I may have stated money wasn't going to be a problem, well now it  is. The cost of plumbing supplies is crazy. $25-30 and up for one 1-1/2" or 1-1/4" copper fitting ! I will try to at least get some outdoor reset as much as the tankless coils will allow.
Thanks for listening. If I can get a camera I will try to post a picture.

What I have learned

@ July 21, 2014 7:39 PM in Suggestions wanted

I asked a lot of people a lot of questions , no one seemed to have an answer. Chris from Winnelson stepped up to the plate. We did a heat loss, I surveyed all of the radiators and looked them up in Dan's EDR book.  Most of the numbers seem pretty good. I used slant fin's hydronic explorer and I was a little "light" on my load. Chris redid it an fudged a few factors I wasn't aware of so worst case at 0° F it is about at 90,000 btuh. So I only need about 9gpm through the system.

The wood boiler is about 100 feet away from the 80gallon indirect so 200 feet round trip + 50% for friction fittings and check valves you got 300x .04 = 12 ft of head + some more for the coil in the indirect. 1" pex both ways

So the wood fired water boiler had a 3/4" tapping and a 007 pump. Today I tied three 3/4" tapping's together and put in a 0014 . The 0014 came with the boiler and I wasn't aware of it.  Tomorrow I will tie three 3/4" returns together. Easier said than done in very limited space.

The indirect heater was circulated through the oil boiler the way it was always done. Into the return and out of the supply. I am going to pipe the heating system return into the 80 gallon indirect, just like a buffer tank, and then into the boiler return. We will see if it works. Customer "Will Not " give up tankless coils so out door reset may be hard to accomplish. I may do Honeywell that plugs into the new aquastat or a tekmar 256 .



@ July 10, 2014 9:29 AM in Tankless Coil ???

I fed the lower coil first and put the aquastat in the upper coil. I really don't know if there is a preferred method , I wasn't able to find any information .

Tankless Coil ???

@ July 8, 2014 8:08 PM in Tankless Coil ???

I know, I know... so 1950's. But I may have a reason. There is an outside wood boiler. In the winter it warms the oil boiler via heat exchanger. Ok so far ?

 My question is, I have a Burnham V34 with two coils, Which coil should the aquastat be placed in ? Upper or lower ? Parallel or series ? I like series. Which coil should get the entering cold water upper or lower ?

It has been at least 20 years since I did any thing like this , I admit I have forgotten. I will probably install a relief valve in between.

It may sound crazy but I plan on installing an indirect also , so when the wood is not being used , I will not have to keep the boiler hot all the time. And no, there is no unusually high demand for hot water just want to get the most out of what ever fuel is being used at the time. I want to try to incorporate outdoor reset also. I don't want to say money is no issue, but it is not as much an obstacle as usual.

Maybe you should lock your new manager in the car with the windows rolled up........ maybe he will understand. "Stupidity" sums it up, common sense is not common anymore. I would not put my life at risk for this guy.


@ July 5, 2014 7:19 AM in Can this boiler leak be fixed? (homeowner w/ pictures)

Not too long ago I replaced a coil in a boiler just like yours. I advised the customer to replace boiler but they had no money so after a long delay we replaced the coil.

 Well, it lasted for about 3 months and the boiler began leaking because it had been neglected for too long (like yours) and the cast iron had rusted through. I got a phone call at 8 pm one night and there was a foot of water in the basement. It cost them about $10-12K for Service Master , damaged property,(furniture from another home was being stored) and a new boiler. Well, at least the basement got cleaned!

My advise, replace the 50 yr old boiler.


@ July 1, 2014 6:47 AM in One of the greatest heating tech' has passed away

I met Chris here on the wall and oil tech talk way back in the early days. Through e-mails and wetstocks and trade shows he became a good friend. I always looked forward to the pictures from the amazing installs at Milne plumbing. I felt a real sense of loss this morning when I saw this. He was real smart and a good person.

Can you

@ June 18, 2014 6:52 AM in CI Rad, intlet & outlet setup - Bushings, nipples, elbows and TRV’s

Can you get a female union for the TRV ?

I wonder

@ June 17, 2014 6:39 AM in CI Rad, intlet & outlet setup - Bushings, nipples, elbows and TRV’s

I wonder if the right and left hand thread was because the valve or fitting would not swing past the supply or return being so close together. You may have to draw them up simultaneously.

Could you find or have some right-left thread nipples made up ?  Can you buy a left hand thread die ?

cold start

@ May 28, 2014 6:54 AM in Oil boiler with summertime leak

Can't really tell from the picture but , it may be a cold start boiler. The aquastat may not maintain temperature until a call for heat or hot water. In the summer when the Amtrol hot water maker is satisfied the burner can be off for extended periods of time and when the boiler cools the leak may appear or the leaking water may not evaporate like it would when the boiler is warm.
When you have it serviced this year, the technician should be able to open up the jacket and try to find the source of the leak. 25 years ? If you switch to gas or not summertime is a good time to replace it. Instead of waiting until cold weather.

primary -secondary

@ May 28, 2014 6:41 AM in Suggestions wanted

 I dug out my books "to get learned up" on this stuff again. Pumping away and primary -secondary made easy. I found my notes from a Dan Holohan seminar on 8-24-05 in New London, Ct. Back before the economy fell apart.

Suggestions wanted

@ May 27, 2014 8:02 PM in Suggestions wanted

Suggestions wanted (or at least considered) Long story , I hooked up a wood boiler for a friend about five years ago. It is an outside boiler and I did not want to mix the water with the system water so I used an eighty gallon indirect water heater as a heat exchanger. The system was a gravity circulation system from the teens or twenties. A Burnham V34 boiler with circulators was installed in the early 1980's. The house is  not insulated and the home owner does not want to compromise the plaster or craftsman style wood trim or siding.

So, to get to the point. They do deep setback and will not change habits. When the thermostat calls for heat so much cold system water returns it causes the oil burner to start. Some other plumber rigged some hokey switch so he could shut off the burner while the wood was going. But now people are away from home and oil burner can't be switched on an off.

 My thought was to disconnect the oil boiler from the loop, tie the main together and use two closely space tees to protect the boiler from all the cold system water on a call for heat. I am probably not doing such a good job trying to explain this. I put the guy off for a year or two but now he wants me to do something next week. Every summer I put him off and fall arrives and then it is too late. 

I don't understand...

@ May 26, 2014 9:13 PM in Taco relay loud constant buzz! help!

I don't understand why SOMEONE doesn't install the new relay that Joe from Taco sent on  3-11-2014 ?  It looks to me like the manufacturer stepped up and went out of his way to offer help . Wouldn't Someone at least try the new part? Unless there is more to the story. I think a technician could fix this problem in about as much time as it took me to respond to this thread. ( I am a slow typist) 


@ May 23, 2014 5:30 PM in Lead Free

Ice , I call the burnt wood "Cajun Plumbing" because of the Blackened boards and beams! Even if I singe the wood even a little I clean it with sand cloth.

 You made realize I have been soldering for over 50 yrs. !  I started helping my Dad when I was about 6. I have soldered with every kind of torch except the gasoline ones from the 40's. I have even used electric. I have used 50/50 60/40 95/5 , lead free , silver, etc. Pipe and fittings,  sheet copper, metal, radiators, lead pipe , etc. Everything from 1/8 " to 4" pipe. Braze, silver braze etc. I once soldered a fitting from almost four feet away , under a hot tub in a celebrities home. I taped the torch to a stick and fed the solder through 3/8" copper tubing.

 So when I say I was surprised to say I had recurring leaks I have a little bit of experience.  Thank you for all the good advice , you too Hot Rod, I try to keep an open mind and it is never too late to learn something.

"aversion to burning wood or paint"


Lead Free

@ May 21, 2014 10:28 PM in Lead Free

 Has anyone , other than me, had trouble soldering the new lead free fittings. I have had two leaks in the last two weeks and I "NEVER" have leaks. Both were on unions for HW AM 100 US thermostatic mixing valve. Solder "took" all the way around the copper pipe but not on the brass union. Maybe I did not scratch the surface enough ? Re-cleaned and re-soldered seemed OK. Not what you need at 5:30 PM

Today was a good day . Perfect weather.  Spent it with a few friends . Worked on my lawn equipment. Went to Longhorn for dinner with my wife's family. Excellent meal , nice waitress , good company.

Happy Birthday M.E.

Every year on this day. Happy Birthday to Colorado's favorite Hydronician, Mark Eatherton. ME too.

we try

@ May 3, 2014 6:51 AM in Repair vs repaired rate.

We try for 100%. Almost never have to leave a customer w/o heat or hot water. But we only serve our customers and they are oil heat not gas. There are not too many oil equipment parts that are that exotic that you can't get them or interchange them to make something work.


@ April 16, 2014 7:10 AM in Buderus GB142/30 no heat as outdoor temps rise

The GB142 comes with an outdoor reset control the AM10, when used the factory default on the base point is 86 degrees, (starting point of the curve). That may be a good base point when running a low temp application, such as in floor radiant. We suggest on a high temp Application like a baseboard job to set the base point at 110 / 120. Cast Iron baseboard or Cast Iron Radiators set the base point at 125. For Air handlers set the base point at 130 / 135 / 140. These are suggestions not the rule. Each system may be set differently according to the heat loss calculation done before hand.

I did a ten second search and found this on Buderus website. Maybe you could read the directions or have some one set up the AM10 for you.
