I am just starting my research so please excuse my ignorance. I've learned I don't want an outdoor wood boiler. As far as indoor I don't know if I can afford a gasifier. I have had the Biasi 3 wood reccomended to me but some people have told me it will create a lot of creosoot in my chimney. I've used a wood stove and clean my chimney once per month. With this boiler dirty my chimney faster than that? Any suggestions would be appreciated.
