I do tend to agree that the best bet for a coal appliance is a masonry chimney. There is no doubt they are the best material.
However, some people (like me) cannot install a Class A metal or masonry chimney easily (or at all) due to house design. Therefore, are forced to run a power or direct vent stove.
I just picked up a Keystoker 90 direct vent stove, used. I'd estimate it's 10 years old at least, maybe more. It's not been well loved, and has a fair amount of internal surface corrosion, etc. But, the power vent assembly is in very good shape yet, and just needs a good cleaning, some seal around the exit, and a lube to be ready for more service. In fact, the entire stove will be in great shape after some good cleaning, paint, and TLC.
Do I like the idea of a motorized vent? Nope. Just something else to make noise, use power, and wear out. Is it my only option for a stove install? Yes, unless I take drastic measures to 'remodel' my home to install a 'real' chimney
If the price of natural gas doubles or more, then I can go back and justify the major expense of installing a permanent vertical chimney. For now, a simple thru the wall vent using 4" pellet pipe out of my basement will be the ticket. The Simpson PelletPro vent is both wood and corn suitable (no mention of coal as I'm sure they've not thought of that), factory sealed, and 400 series stainless lined. Should work great.
