If Washington state sells a hardwood pellet, I don't know about it. I do a pretty good job cleaning my stove regularly and all I know is I save about $1500+ a year or more by burning my pellets. More importantly, I have stable, affordable heating costs and my house is 2100 sq/ft. Since we get a more full, complete heat without allergins flying through the vents, and we like the scent, it's a double winner. That Harman pays for itself next year. And when that happens, I have permanent heat reduction costs... unless the biomass fuels go off the charts in costs. The only drawback is the time and effort to clean stove and flue, and the securing of the pellet and then transitioning it to the stove. Not a big deal. For that sacrifice, I don't see $500+ electric bills in the heart of winter and at least I have an option in the fuel I buy whereas with electricity, I don't have any options. No oil here.
