I personally installed both an EFM 350 (1982) (Parent’s house) and Axeman Anderson 130 (1984) (Sister’s House) in the Minersville PA area. By far I loved the EFM, however the Axeman Anderson is a workhorse it burns any size coal you put in it, rice, pea, buckwheat. Or pick the coal off the rock banks. But it is not suited for a small house. Needs to run, great for a bigger building.
The EFM 350 never gave us much problems and it was sized perfect for today’s better insulated homes. We easily heated a 3000 sq feet 3 zone house.
EFM design is more expense to build but not a three thousand differential more like $1000 because of the S20 stoker mechanism. When Van-wert was in business their units were similar to EFM and they were much cheaper.
And lets remember something EFM is a business and regardless what we wish EFM's bread and butter is not the EFM Coal stokers
. So what EFM does is market segmenting, there are people out there who will pay the premium for an EFM 520. EFM is happy to make coal boilers for that profit, this way they can say they still make a coal boiler
. They make a good profit per unit and pay more attention to EFM's real business that pays their bills. Yes “OIL UNITS” So wake up and smell the roses..
Maybe EFM should franchise their EFM Coal units to Keystoker and take a fixed franchise commission for each EFM unit. This way they would know what they will receive per unit in profit and Keystoker can work on offering the smaller EFM models and reducing unit cost. http://www.keystoker.com/coaloilboilers.html
