I think highly of the EFM's, I would have one...an older one. But would be somewhat reluctant to buying a new one.
Now the European designs are a bit more progressive...they are held to some stringent emissions over there. Low emission's output and efficient combustion both added up to using less fuel...it is all good.
.....and how expensive is this set-up????? ......dealer support??????? Nice to look at and probably works very well, but....... SSDD, and thanks for posting. Glad most everyone is being kind to our environment.
I've spoken to a man from poland (now living in the US) who is familiar w/ these types of coal stokers. Most of those stokers have significant drawbacks. They're not as durable, the modulated air/fuel creates problems w/ the burn and reduces the quality of coal that can be burned sucessfully to a narrow set of qualifications, they require more maintenance, and simply will not work w/ american anthracite or any high cokebutton, low AFT bituminous (american) coals. They would work well with western/alaskan subbit.
I looked into those units a little, I think berlin is right if the coal swells there will be a huge mess to pick out of there. I really wish there was a company that made a soft coal stoker stove like the stokermatic or combustioneer but, I guess there not a market for them.
I know those are new, and I know nothing ever goes wrong with sensors and electronic controls, but nearly $3k (with shipping) for what essentially is a 15 lb/hr stoker seems pretty expensive compared to what you'd pay for a good used industrial-strength domestic unit of comparable capacity.
I agree with Pacowy, it is built like a toy compared to an EFM. Dividing the EFM purchase price by 50 years makes EFM's a bargain!
The $3K price quoted on the EBay ad above does not appear to include the boiler.
It is encouraging that they say they can burn biofuels with a stoker pot similar to an EFM. If politicians decide to tax coal for home heating some day, I am sure the members of this forum will figure out how to "tweak" our EFM's to burn 100 percent biofuels.
