EFM 900 Is This a Decent Unit

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.

Hello, first time poster, but long time coal burner...

I have an aging, installed by my father in 1952, EFM 520 steam system that I want to replace. This furnace is of the vintage where the front cover is not hinged, but you lift it off. About 15 years ago I purchased, sight unseen, another EFM, which I believed to be a 520 but which turned out to be a larger unit that from looking on this forum, I believe is an EFM 900. The 520 is in bad shape, well, the base mostly and the sheet metal, which I understand can be repaired/replaced, but it also has some other issues. This is also a steam system and I would like to convert to hot water.

Is the 900 a good unit? I've read here and see that the set up is more complex and maybe more prone to problems than the 520. When I bought this it was converted to oil, so the coal unit, which I do have seems to have been used very little. I am considering installing this in an outbuilding and piping the heat into the house and perhaps, at least in time another outbuilding or garage, so the additional capacity might be utilized.

Any information or opinions are much appreciated and thank you in advance. Jim

If you have a 900 in very good condition, you have a piece of gold. There are many commercial uses for the unit and it could be sold in a few minutes if you place an ad.

The model is owned by Mark's in Shenandoah and he would have any repair parts, but most will tell you that you probably won't ever need parts.

Anczarski Enterprises 230 S. Main St. Shenandoah 17976 (570) 462-0748

Call Joe for more information or advice for 520 parts or even swapping the unit.

Great news, thanks for the quick reply. If I get the serial/model number is there an easy way to verify its vintage? I think it was originally installed in the 1960's, but again, used very little as a coal unit. I will also follow up with the dealer in Shenandoah. Thanks again, Jim

I couldn't find a plate with a serial or model number, where should I look for this. I did see a stamping of 700 AP on the base so I guess this is a model 700? What is the general assessment of this model? Thanks

The 700's were discontinued along with the 350's in the early '70's. They were also built like iron and are very desirable. Look for the plate riveted to the stoker assembly for the number.

Sorry for the delayed response.

Regarding the serial number..when I looked for the serial number it turns out to be on the side of the boiler that is facing down, that is not easily accessible. I have someone coming to look at doing an installation for me, probably Friday of this week, so I will have a better idea of which direction I will be going, that is, selling the 520 or refurbishing the 520 and selling the 700.

From the description I read on another thread here, it looks like the 520 is the "highboy" as the domestic coil is located in the front. I live in lower Northumberland county. I will try to post early next week if I have a clear direction.

Jim
