I agree it's easier and far safer to use a chimney flue. Several years ago Jeff at AHS asked me if I know of any testing labs that could certify the coal gun. The conversation was in the context of direct venting. I couldn't help with any suggestions but it got me to thinking about how I would do it. My suggestion to have individual exhaust systems for idle fire and production fire conditions is in my way of thinking what's needed for a fail safe design. I admit I don't know much about safety code criteria for CO leakage in any power vent design. But it is certainly more difficult in a boiler or furnace where the volume of the fire is much larger. At the time Jeff was looking to expand his sales and felt a direct vent coal gun would to that. My point is that it might be possible to do it safely. It's up to the manufacturer to step up, produce a design and get the safety approval testing done. With the exception of the Coaltrol, the residential coal stoves, boiler and furnaces are still 50+ year old designs. Nothing wrong with that but it excludes sales of large central heating units to people who don't or can't have a chimney.
We have an energy crisis looming in this country that is not being addressed. All of us coal burners have solved our personal energy crisis (cost) but we are a pittance in the overall solution. For the life of me I can't understand why the coal appliance manufactures have not gotten together formed a trade association, research council, etc. to promote Anthracite Coal for residential heating. Sure coal is a dirty name in the public eye, but that's Bitumimous coal. Most don't know the difference. When you realize that 2/3 of the BTU content in coal is wasted when you burn coal to make electricty any reasonable person would look for a better way that uses the energy more wisely. Combine that with the fact that it's a domestic product, provides work here and keeps capital here it's a no brainer. Where's the leadership? Oh, I know it's more important to talk about the pastor, the hooker, gun rights or ethnic fears. End of rant.
