EFM Steam Boiler Vs. Hot Water???

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.

Can anyone tell me the difference in design between an EFM steam boiler and a EFM hot water stoker? Can a coal-fired EFM steam boiler be used or
retrofited to a hot water baseboard appilcation? Was the 520 made in both steam and hot water configurations? If so, are most components the same?

The 520 boiler can be used for steam or hot water. The only difference in the kits are the controls. If it has been used for steam and not properly set up or maintained, look for rust damage. Otherwise, it's the exact same boiler and stoker.
