EFM 520

PostBy: coal stoker On: Sun Feb 22, 2015 5:27 pm

Hello,

I am currently trying to determine the footprint I will require for the EFM 520 I will purchase. I am planning on using a 55 gallon drum to feed the auger, and refill the barrel from a coal bin close by. I guess what I am really trying to find out is how much additional space will I need for the auger and the drum.

Thanks for the help

Welcome to the forum!
I am presently feeding my EFM 520 from a 55 gallon drum. The drum is 21 inches from the base and is elevated 12 inches from the floor. The base is on a pad 4 inches off the floor. The feed tube has a 12 inch extension to get it into the drum. If you want the drum to sit on the floor, much more space and feed tube/worm length would be required. This is a temporary set up for me until I build a coal bin in an adjacent room. Having the drum elevated 12 inches requires significantly more lifting when loading. It all depends on how much room you have to work with, but I would highly recommend a larger capacity coal bin over a 55 gallon drum, unless you don't mind the manual daily loading. I am ready to say good-bye to the drum and hello to a minimum 3 ton coal bin. You will also want to make sure that your coal is nice and dry for the drum so that the coal flows well. Make sure that you look at the posts regarding sulfur smell and that you purchase several carbon monoxide detectors before start up.

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:

We replaced an OWB with an EFM520 installed in a truck box. We built the boiler room 8.5' x 10',that is a snug fit but not much could be changed & keep it inside the walls. If you haven't looked at the thread yet look thru the pics for an idea of how the 520 fits in that space.It might help you with your plans.

Thanks,

I appreciate the feedback, I have to say that I am getting pretty excited about the thought of not having to fill my OWB anymore next year.
Getting this coal boiler I think will allow me to do something with my weekends besides cutting firewood, and maybe get some of
the other projects that I have been meaning to get to.
I will be sure to get some pics of the before during and after of the install. This way I can get some feedback from you guys who have the knowledge that I lack, being this will be my first time using coal to heat. I grew up burning firewood I guess that is why I went with the OWB as my first attempt to get away from oil.

I don't know if this will help you our not. If you go to the page 4, the 7th reply down of the following thread, you will see an attachment that says "layout", it is for a skid system, but the barrel used to be right where the floor auger box is now.

If you intend to burn only rice coal and don't need to run the stoker above 4 teeth, you can get away with a shorter auger. I don't recommend it, but if space is very tight you can do it.

This is what a 520 looks like with 60" of auger pipe, a 55 gallon drum, and the auger centered in the drum. I will try to get the measurements this week.

If you have enough room to pull the drum away from the auger, you can use a single piece of pipe and skip the coupler.

I burned out of a drum the first winter. I used the pot auger and short pipe. Had to keep the drum lid clamped down, otherwise I would get fumes back through the coal.

If you keep your boiler height low by placing your boiler on 1-7/8" high thick bricks, you can keep your auger low going into the drum. Every little bit helps when you are lifting coal into the drum.

Also, if you have the room in your basement to go to skid/bulk bags some day, it gives you clearance for the auger to go under the skid.

It is getting to the end of the wood burning season for me, I am hoping this is the last season that I will be feeding my OWB about 15 plus cords a year. I spoke to my guy in Ashland PA who I am buying my refurbished EFM 520 from, I was a little disappointed when he said that he has been so busy he has not had time to work on it but since I am shooting for next season I am not worried.
I am sure I will be ready in time. VermontDay has a slick design with the skid system and this is what I am hoping to have in place for next heating season. The NY Hudson Valley has been especially wicked this year and with this in mind I have realized that burning wood has been good to me but I think coal will be better. I am going to post pics of my install, I have to say that I am really looking forward to only buying coal feeding my boiler with an auger feed and just emptying a pan of ashes each day, this sound like a vacation compared to cutting wood and feeding the beast that feeds my 3500 sq. ft. home now.
Oh buy the way you may see a WoodMaster 4400 for sale soon as soon as I get the hang of things.
Good luck all Thanks.

Outdoor wood boilers are good if you are trying to clear-cut a forest and quickly dispose of the wood, but that is about it. My house used to be heated with a wood boiler also, but mine was inside. I replaced it with an EFM and wished I had done it sooner. With the high btu content of anthracite and efficiency of the boiler, it now costs me less to heat the home with anthracite than wood. I also get to skip the smoke, creosote, bugs, and 2 am reloads. :)

I still feed my EFM out of a drum...not a big deal to top it off when I go down to take out the ashes.

As I continue my search for a used or refurbished EFM 520 I am approached with the decision as to what I should be paying for this unit and what condition I should expect to receive it in.
I understand that boiler purchased as is, is just that and buyer beware should be considered, but if I am buying from one of the many people out there that are in the business of refurbishing these awesome boilers again I wonder what I should expect to pay and what that should include.
I am asking because this is an investment in the future of heating my home and I don't want to get burned, pardon the pun.
I really love this boiler, I am hoping that one of the very experienced members of this forum can lend me some advice.
I know this is probably could be a sensitive subject giving opinions on other peoples work, but without stepping on anybody's
toes I just need a little guidance.
I appreciate any feedback thanks in advance

This is what I have been looking for
It is nice and clean and dry been in service about 20 years.
Complete with all plumbing and accessories, circ. pumps, vents, expansion tank, DHW coil ( 4 years old), oil gun which will get removed and install the supplied flange cover.
I secured it today and will have it home once the snow clears, I cant get to it yet but spring is working its magic and soon it will be home.
First step in my move away from the OWB and onto coal.
