EFM 520

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.

Put a piece of tape over the gauge and let it run for a few days. :D

On a fresh install it is not uncommon for the pressure to drop after a few days...due to air being removed from the system.

Just sitting here enjoying an adult beverage looking over some of the post's and comments from you guys on this forum from my thread EFM 520.
I have to say that the end result so far is all that I hoped it would be!
This is truly an automatic system that just runs and runs,
I find myself coming home from work just to check on status, and it never changes...
Click click click whurr whurr whurr and so on, love it.
I am actually looking forward to colder weather to see how things work out, not that I am worried but all this thing does is just sit there and work quietly along.
No need to cut wood and pick it up and stack it and then load it into an OWB.
Oh then repeat!!!!!!!!
Just order up your coal at the beginning of the season load up your bulk bags on skids and kick back and enjoy life.
What will I do with all my spare time, uh oh here comes the wife I guess I have my answer.
Thanks a lot guys for all help, I couldn't have done it without you
Best regards,
CS

I cant tell you the answer to your question as my set up is a little unconventional. Just make sure you have enough room for the Barca lounger and minifridge directly in front :D . You can have no idea how happy youll be that you went with an efm :) Post lots of pics so others can learn from your setup and cause some of us here just like to look a coal pics. :oops:

see I told ya :cheers:

Glad you're enjoying your new toy instead of working on it. They are fascinating things to watch.

Good luck,

Thanks guys,
I do still have a little work left, I am working on the insulation for it and refinishing the jackets.
Just a little at a time, not as much urgency now.
It does make the room a great place to sit enjoy the radiant heat and have a cold one :) :) :)
Best regards

You will be impressed how easily it will heat your home when we get really cold weather.

Coal is a very steady, powerful fuel. You never saw any of those big battleships burning wood!

Finally finished refinishing the jackets and getting them installed.
I must say I am pleased with the results.
I did not realize until reassembly that I was missing the top panel on the venting side, I checked back on old pics and saw it was missing from the install I purchased from. Maybe a DHW coil issue and was discarded or lost :o

Looks factory new! Nice!

Well, at least with that panel off you can keep a good eye on your DHW coil gasket.

Thanks Don,

Not sure what to do next, it was bitter sweet putting on the final panel.
It has been a lot of fun doing this build, and I am very glad that I chose to do the re-furb myself.
I now have an intimate understanding of how my 520 works, and also now the condition of all the parts involved.
Just have to figure out the next project now :D :D :D :D
