EFM 350

Stoker Coal Boilers automatically feed the coal and have controls and pumps just like any conventions boiler. They are intended to be used as a primary heat and often have domestic hot water coils as an added bonus. They can be set up independently or in dual sytem with your existing oil/gas boiler. They can accommodate both hot water base board or steam plumbing.

Did some plumbing today. The close fit between the top of the boiler and the ductwork was worrying me, but a 1 1/4" street el did the trick with a little room to spare.

Tight fit indeed!

It will be well worth the effort when you finally get that 350 up and running. It took me almost two months to get my dads 520 installed, but we finally got it fired last Thursday night. It effortlessly heats his 3000 sq. ft, provides unlimited hot water, and is nearly silent...what's not to like? :D

Plumbing is almost done, just need to finish the runs to the heat exchanger. The DHW pipes are done and the coil is pressurized. :D
Photos tomorrow!

It's getting chilly down there too! Fortunately I'm currently heating for free with the cellar coal from Avenel and the Harman. :D

Finally.
The boiler is pressurized, as is the DHW coil. I had 2 leaks, one where the DHW coil meets the boiler (tightened the nuts up) and 1 elbow on the feed to the heat exchanger (forgot to sweat one side-- :oops: ). I ran the circulator pump until the air bleed stopped hissing. So far so good.
I wanted to keep all the pipes on one side of the boiler, I still need room to work on it!
I set it up for 2 zones, eventually I'd like to run pipes to the kitchen for a radiator. I had to make sure I left room for the smoke pipe. I also still have to install supports for the pipes, they're hanging on Romex and cable ties right now.
So here's the photos:

In this photo you can see the heat exchanger as well as the DHW pipe to the boiler.

One minor problem...no coal...
I'm going to build a false bottom in the bin angled towards the auger.
Electrical is next. :shock:

I recently saw a home-made Modine made from finned baseboard. It was cubic and made of many rows. It did the job and it was cheap.

The heat exchanger wasn't that expensive, I just forgot how much it was. I think it was around $140 plus shipping.

I saw one yesterday made out of a Camaro radiator and a box fan. It threw a ton of heat!

Will you have it 'clicking' before Dec 1st? It's looking done from the pics. Don't get sidelined by the multiple requests for you valuable time. (In other words, tell them to go pound sand!) Can't do that here tonight, frost went in 4" last night. I can see the snow-making lights, hear the big Cat generator, compressors and the howl of the guns without going outside.
They are across the valley, but you can hear them a mile away.
Costs about 1K per hour when it is all fired up....ouch! I'd trade the diesel bill for a weeks pay anytime.
Don't stop now John, you can nearly taste it!! :!: :) ;) :roll: :lol:
"Political correctness is a doctrine, fostered by a delusional, illogical minority, and rabidly promoted by an unscrupulous mainstream media, which holds forth the proposition that it is entirely possible to pick up a 'piece of human solid waste' by the clean end." More true today....
