Just so there isn't any confusion - I'm looking at pellet vent for a DIRECT vent Keystoker 90, not a regular vent system stove. Direct (or power) vent is pretty much my only option to get a stove in this house, especially if it has to go in the (finished) basement.
The only other option is one of Jerry's Econo Sidewinders placed in front of our existing gas fireplace and tapped into the Class A chimney it has. It would just barely fit. But then I worry about the noise right in the same room as the TV. I run into either a window within 4' of where I'd vent a direct or power vent stove or no access at all to the outside. It's 2 story, so access to the roof isn't easy, either, for a stove on the first floor.
I'm a bit of a bizarre person in that I really can't justify a stove with my current natural gas prices. But, I love stoves and want to have one in the house as a focal point of warmth and backup. If I could pay back a stove in a year or two like a lot of you here, I'd hack a hole for a chimney just about anywhere I could to make it work.
But, since that's not the case, I need to do this in the most friendly way to the house and make it almost reversible in case it doesn't work out. I could easily deal with a little ash or dust, etc. and colder rooms at the ends of the house, but my wonderful wife may not, especially again, if it's really not saving us a lot of money. I can easily see where it might go with her dealing with another one of my 'science projects'. Not good....
These modern homes with direct vent furnaces (and we even have a direct vent gas water heater) just weren't designed to accomodate solid fuel heating devices.
