Just to get back on topic here, I don't really care what my neighbors think of the boiler I put in if in fact I do put one in, I am in a rural area where my neighbors are quite far away, only one of them would be in a direction where smoke may possibly blow and that wouldn't happen often at his distance from me, and the wind would have to be just right, of the people living in this area we all burn wood and one guy already has an OWB, one of the less efficient models I mentioned in my original post. Also I haven't decided on which type I would get, the new efficient models, gassers as many of you call them, or the older type like the Central Classic. I only know one guy with a gasser type and many with the older style, I don't see any problems with the smoke from the older style as long as one burns decent wood, you burn garbage or green pine, then ya they smoke pretty bad. Most I have seen smoke minimally unless they are calling for heat then they smoke some until the draft closes again or blower kicks off, whichever style you have. The fella I know with the gasser type has a brand I am not familiar with and right now cannot remember the name, it isn't a Central though, he says his has small diameter pipes which the smoke travels through and these easily become clogged with creosote if your wood is not 100% dry, he has to go out with some brass brushes on long steel rods and ream out these ports or they clog and the stove isn't able to do it's job, seems like a big pain in the ***** to me, or maybe just a poor design.
