Refurbish 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.

I have a severly rusted EFM 520. The EFM 520 is severly rusted in the back wall which mounts the stovepipe receptor. Does anyone have any suggestions to resurrect this unit? Will EFM or or any of their dealers refurbish an EFM 520? What does a new EFM 520 unit cost? Will EFM be manufacturing the EFM 350 unit and what will that cost because our home is only 1500 square foot and the EFM 520 is OVERKILL? Is there another good anthracite rice coal furnace by another company that is better sized to our home and better priced? If you have any good ideas then leave a message here or just call me at 484-547-8630. Thanks in advance. Jay

I got ahold of scrapperjr and he said he could make me a set of back plates. Lucked out and found a welder who is currently working on historic first steam locomotives at STEAM TOWN. This guy really knows steam, pressure vessels and metallurgy and is working on high pressure steam engines welding and riveting daily. He works out of Hometown, PA. I recommend him to anyone who wants a good analysis of their unit for repairs. He took a few moments and saw significant steam scoring around the coil plate that cut deep into the supporting back of the furnace that the coil plate bolts on. I do not have the trained eye but he spotted it immediately.

Please don't start two topics on the same subject, if I had seen this before I would have locked it then.
