a HUGE thank you to You BobMac and Krooser. I now have a stove that has never worked so well. And I truly mean never. Mom told me that dad was the one who installed the stove years and years ago and I'll bet anything it was the type of deal where you screw a few things together, attach this to that, hook up these wires and viola! pellet stove installed. Although dad was a skilled electrician, he was a jack-of-all-trades-master-of-none type in most other stereotypically "manly man" areas. I don't think he ever realized the auger-hopper problem even if he knew how well sealed the stove needed to be to run correctly. And, I'm fairly certain he never gave it a thoroughly thorough cleaning (or he might have found that auger-hopper problem like I did). But between sealing up the stove (auger, hopper, and all) and vacuuming every square inch of it inside and out (as well as the vent pipes) I now know what a good flame looks like... as well as a blow torch flame which I must say is quite impressive. And, to top it off, I barely have to have the damper open at all (keeping it somewhere between "closed" and "half-way").
The Southern Indiana hardwood pellets work great in this dinosaur (my best guess is it's from '93-'95). They are burning fast enough so they don't pile up and after 2.5 days there's very little ash build up. And the stove, which is in the unfinished/cement floors and walls basement, is keeping it and the rest of our ranch-style house about 70 degrees. That's an average because when I turn on a vent fan, that dad installed in the hallway by the bedrooms at the end of the house closest to the stove, to pull up the heat from the basement the main living areas rise up to 72 degrees (even on the far side of the stove/fan set up) and the basement is about 68. And, without running the fan the basement stays right at 70 degrees. Not bad, I'd say, and WAY better than heating everything with the furnace/boiler that uses propane.
Gotta admit... I think I'm hooked on burning wood pellets.
