When we were looking for a house, I really wanted to find one with a wood stove. Wife wasn't too crazy about that idea. She grew up with one and said they were really messy. We were blessed to buy a house that had one of these in it:
Our house is far from airtight. We have a furnace in the basement to heat the downstairs, and a furnace in the attic to heat upstairs. They both run on LP gas. This little number, in the corner of the kitchen, doesn't really heat the whole house, or the whole downstairs, for that matter. But, except in the coldest temps (20 degrees or so) it really does a nice job of warming a large area and it keeps the furnace from running so often. When the temps are in the 40's it's almost too much, and I have to shut it off if it gets above 50 because it's just too warm.
It runs through a 40 pound bag of pellets about once a day. As it runs, it produces ash which falls into an ash pan below the fire pot. There is no smoke, no smell, no dust, no messy wood, and no smoke from the flue. It's pretty doggone nice. It has to be cleaned out about once a week or so, which is about a 45 to 60 minute job to do thoroughly. That part is messy, but I use a shop vac so it isn't too bad. Also, if the power fails, the stove shuts down as there will be no way to feed the pellets or run the blower (unless you have a gas generator). In all, I'm pleased with it, and would recommend it to anyone looking for alternative ways to heat your home.
