I'm glad my little bits of advice helped. The plumbing looks fine from here.

You're gonna love that boiler more and more as time goes by.

Enjoyed the videos too!

I created a playlist on my Youtube channel for the 18 videos of this install. Please let me know if this link doesn't work.
https://www.youtube.com/playlist?list=PLFU8SaWNbzx_7St31g7hdDqh6xa9WgMOG

7 of 18 are currently uploaded, number 8 should be done soon.

Enjoy!

Nice job that is a good looking boiler and like the videos.

Question I see you have a copper to steel connection are concerned about not using a dielectric connection. The reason I ask is I also have a copper to steel and it hit me last night that I mess up on that connection and should have used brass or bronze in between that connection. This a question not any criticism I know it would take sometime for any corrosion to happen I may leave mine the way it is and fix it later.

I don't think copper to black iron (or steel) connections are a problem in closed hydronic systems. Once the system is closed and running for a few weeks, the oxygen dissolves out. No oxygen, no oxidization (rust) problems.

Nice job. Do you plan to out the covers on eventually?

What did you end up doing with the controls?

Well, I guess I can answer the controls question.

It is using a Honeywell triple aquastat and a Honeywell stoker controller as a timer.

Terminal #4 on the stoker controller/timer is run to the ZR terminal on the aquastat providing a HI limit control for the timer.

The TT terminals on both controllers are not used. The pump is constantly running so the boiler runs on the low limit of the aquastat, 180 degrees. This is a very simple primary/secondary system, no bypass, no air scoop, no second expansion tank, just one 1.25" pipe out to the oil boiler and one 1.25" pipe back to the EFM. The pump is on the supply side of the EFM, pumping away.

We did plumb 3/4" stubs on the supply and return to connect a basement radiator in the future.

That works.

How warm is the basement after day 1?

Edit: I made it to Part 11, and got left hanging.

The boiler room itself is rather small. it's abut 80 degrees. The rest of the basement is cooler, about 68 degrees. As Don said there are two 3/4" stub outs for a future radiator. The basement is chopped up into several rooms. There's a bedroom, bathroom and a recreation/bar room, all with ductwork serving them. Besides the boiler room there are two utility area. One has the oil boiler and indirect water heater, the other has the electric panels, gun safe etc. That's the coldest area of the basement and where the radiator will go eventually.

Although I was glad to get the covers I'm not sure I'm going to install them.

Wish I had done this 14 years ago! :roll:

If the boiler room is 80, putting the covers on would be a good idea. The boiler temperature will stay a little higher, and that will transfer a little more heat to the rest of the basement via the piping.

Did you end up running the auger into the bin?

Good to hear the EFM is doing so well already!

Right now I'm running out of a 55 gallon drum with a sealed lid with just the stoker auger. I've purchased an auger extension from scrapper and it will go in the bin. I'm going to finish out the season with the drum and reconfigure the bin during the off season. I kind of like the 80 degree boiler room for now. Wife likes it cool up stairs (68*) so its a nice warm spot to be.

Coal Kirk and Don,

I really enjoyed the videos, and applaud the simplicity of your system. Way to knock it out in a day.

What size is the single expansion tank?

I could tell you were worn out by Yuengling time!

Slick install Coalkirk. To me your fan seems pretty noisy. Is it vibrating or something?
