Rushing to get my boiler installed before winter, Its aan EFM 700 with a Jentleman Janitor stoker, we have tested our local Bituminous and it burns well, should be able to burn Anthracite or Bit which is difficult to do.
Moving right along, chimney done, 1" pex al pex insulated with pipe insulation, inside sch 30 pvc and 3 inches of closed cell foam around that buried at least 24" deep, (frost line is 18" here).
