Thanks for the video. Growing up in our house in Pennsylvania (1969 - 1975) we had a EFM coal stoker, but it was a little different than this one. I always lived in fear of the fire going out because it was just me and mom, and neither of us knew how to relight it, so we'd have to call our "coal guy". In 2013 I went back to visit my home town and stay with the folks who bought my house after mom passed away. THAT EFM stoker is STILL THERE and still works great! wish I could attack photos here!!

Great explanation and overview. In virginia i service oil and gas boilers and heat pumps. Never seen a coal boiler. Did have a coal boiler in my house in North Carolina long ago when i was a boy, but it was changed to oil when I was still very young.

Coal boilers are COOL! And warm too.

impressive coal fired residential boiler.

Thank you so much for making this vid I have a 1938 motor stoker and I had no idea how to adjust the worm speed and finding any info for it is hard. The set up is similar but at least now I can count the teeth and know where to put it back to if im wrong

Awesome video. I'm lucky to have natural gas mod con boiler, but I would love to fire a coal boiler at least few times in my life. Seems almost therapeutic..

If anyone reading this has ever had the kitchen sink drain slow way down or get plugged up the hot water mixer valve is to blame. I'm 66 and anyone around my age remembers how you had to be careful not to burn yourself when using hot water in the kitchen or bathroom. Since the " oh we need mixer valves to prevent people from burning themselves " idiots as how did we ever survive before these people had to " protect us " One advantage of not having a mixer valve on your hot water was all the grease your mom and dad dumped down the drain was melted and flowed into the sewer ot septic tank and the drain line rarely plugged up. My kitchen sink drain has always been trouble since I moved in 20+ years ago. 4 months ago talking with a plumber over coffee he reminded me why his business is so good. When I got home I raised the mixer valve to its highest setting allowing only hot water with no cold water added. In two weeks my slow drain in the kitchen went back to like a new drain works. If you do this post a reminder above each sink that the hot water will be really hot for your wife and any visitor using the facilities. If modern technology is so nice then why are we using a coal stoker designed in 1922? Just an FYI for any tired of slow kitchen drain pipes. Complex solutions to simple problems seem to be the norm now yet when we were kids simple solutions to complex problems were allowed until the " oh we must protect the public people came along" and created a aggravating problem that didn't exist prior to wholesale installation of hot water mixer valves. Long live the EFM coal boiler and no I don't work for them I'm retired and probably think too much. Stay safe and warm the old fashioned way by keeping Americans working.

Nice system. But I have a feeling if something happens to you, nobody else will be able to run that thing.

I need your help!! I’m in dire need! I have almost the same unit and mine had a deeeeeep hole in the coal bin and it also smelled like sulfur when I walked in the house. Now my unit isn’t pulling coal into the coal pale. I need help! Please! I’m in Pennsylvania and we had a snow storm yesterday!

Chad if your fire goes out when your not calling for heat then it could be your timer or a number other factors but check the timer is working with a properly maintained furnace and good coal timer should be set at 2 minutes every hr

May I ask what the primary purpose of the barometric damper is with a blower to support combustion? Is it primarily for “idle” or. no heat demand? (I understand the stack needs to present a fixed draft with varying atmospheric conditions thus the damper). In other words, barometric dampers make more sense with a natural draft stove than with a “power” burner. Very interested to know this. Thanks

What do you have your timer set at for the on/off time of the feeder and air supply?

Oh my good..this was old Technology even back in 1940

I was watching a informative video by Stoker Don about the correct rotation of an EFM stoker and noticed yours is going when looking at the gearbox backwards. You need to reverse the connections on the motor to reverse the direction it starts up. When looking at the gearbox/fan blower assembly the gearbox should rotate counter clockwise. Yours is going clockwise, it will still deliver air to the pot just not enough air as it is designed to. No matter which way the blower assembly is turning it will not affect the direction of the stoker itself. By getting the blower turning in the proper direction it should improve the efficiency of the burner as it will have more air to burn the coal. By making this change it will give the burner a higher fire using less coal because there will be a lot more air flowing into the burner pot. My neighbor who also runs an EFM 520 when I saw the video about correct motor rotation by Stoker Don we discovered his was turning the wrong way his still had the original motor which has a reverse switch making it very easy to reverse the rotation of the motor. When he opened the firebox door he was astounded by how much higher the flame was and how much more air was flowing into the burner pot and stated he is using less fuel. Easy way to find out I'm correct is shut of the boiler and watch the motor shaft so just before it stops you can determine the way the motor is turning. Looking at the blower housing from the gearbox the shaft should be turning counter clockwise. If it turns clockwise as yours is it needs to be corrected as it wasn't designed to run that way. Check out the video Stoker Don did on the correct rotation of the motor. kzfaq.info/get/bejne/sJ6Sfc2F3rexc3U.html Just an FYI

I have an efm as well.I don’t see your steam drainage to release the hot steam water.I have a small copper pipe that connects to the top of the furnace to a steam pipe.Just curious if you have the same design as mine.

Excellent video

Curious if you use the coal year round? Looks like maybe there is a spot for an oil gun there for the warmer months.

Hey Tim, I grew up in Tonawanda and my brother lives in Chaffee, just outside of Arcade, He has a wood furnace in his basement and uses it all winter. I'm in the Albany NY area now and using oil. I will have to look into a coal one, cheaper, I believe, isnt it?

I soak those hard wood chips in k1 for my leisure line stoker.

What kind of oil did you use on the blower motor?

How many tons do you think you burn in this coal boiler ?

Why is your pipework not lagged? Loosing a lot of heat there!

can you burn wood in that coal stove

I don't like how it's electricity Dependant.

I'm sorry but have ever cleaned your kitchen sink? Because it looked like the sides of an outhouse! God, with the money your supposedly saving using coal hire a cleaning company once in a while!
