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.

I now own this bad boy, American Radiator 3 pass and the price was right...free! There's another one like it on the way. Took four of us to lift it into the truck.
Did you ever that thing hooked up?

No, it's out in the barn. I have another one exactly like it now. I'm going to use them in the pole barn if I ever get lines from the house for heating.

The other radiators are still sitting there too, the only hydronic zone I have completed so far is the kitchen.

I found the date of the last cleaning, it was November 02, 2014. I let it go too long. The 10 gallon shop vac felt like I was carrying a bag of bricks up the cellar stairs when I was finished. :lol:

Hard to tell what it is. There's a baffle first and then the blades of the fan behind it.

I would like to thank Scottscoaled for the very nice EFM temperature/pressure gauge. It's perfect!!! I've been wanting one of these for a while.

I got the bug to start working on those radiators I have for the house. I need to get them out of the barn, they are in the way. There are 7 of them, they all need to be powerwashed first. 2 came out of the house I grew up in, one came from Dave (thank you), and the other 4 came from eBay, those 4 were on a steam system so they need to be flushed out thoroughly and I have to use the fire-wrench to get the plug out of the one end, as well as the plug where the air bleed goes. 3 of them have heavy coats of paint on them too.

The other 3 were on hot water systems, they don’t have a lot of paint on them either.

Once they are cleaned and painted I can sit them where they will eventually be connected in the various rooms in the house.

I have 3 matching units for downstairs, 2 identical 6 pass units for the front room and one that had an additional section or two for the dining room.

For upstairs I have 2 that match from my childhood house, the one from Dave, and a kinda tall 6 pass that weighs a ton. Mix and match!!!

All seat-of-the-pants engineering here. The correct way is to do a bunch of cal-cul-la-tions that I don’t quite understand (including a heat loss figure for the house…oh I got that already…a lot), and research and research to try and find the BTU output for each radiator so they are sized correctly.
Sections are added or removed to obtain the correct output.

Or…I can just look at the radiator and think about what I remember about the sizes of radiators I’ve seen in houses all my life and say “Yea, that looks about right” like I did in the kitchen.

Start watching eBay for good deals on zone valves and thermostats...then you can set each room at whatever temperature you want. :)

Good idea. At this point I'm happy just to be able to get away from forced hot air. I just looked back, I collected those radiators 4 years ago!

My plan is just to have the 1st and 2nd floor on separate zones. Lot of work involved, plus I plan to move the EFM as well, further away from the bin once the oil furnace is gone so I can get around it without twisting and squeezing. I can just fit between the boiler and the coal bin now-sideways. I plan on doing all the plumbing in the house first, working towards the boiler, same as I did with the kitchen zone.

The Lennox oil furnace will be for sale once I get that far along. Been using it as an air handler for years now, maybe 20 hours on the burner...if that much.

How hard is it to run the piping upstairs? I ended up running some pex through the corner of a downstairs closet.

Excellent question, and one I have spent lots of time thinking about. The bathroom, which is on the 2nd floor, is above the cellar stairs. I can easily get the piping up to the second floor there. I'm just not sure exactly how I'm going to make the run from room to room to connect all 4 radiators. I might run the pipes along the baseboard and box them in. There's not a lot of options unless I open the first floor ceiling, which I really don't want to do. I remember my aunt and uncle's house that had central steam heat installed well after the house was built, the plumbers just ran the iron pipe right through the 1st floor rooms, they were painted the same color as the walls. :o

My grandmothers Victorian is the same way. I never thought it looked out of place, just part of having a 100+ year old home.
