Wouldn't / couldn't of done it with out this site. I am pumped although it will probably be a while 'till I am actually heating with the thing. Zenon was pretty adamant that the Biomass was the way to go for an indoor installation because of its integrated draft inducer. I was ready to go for an EKO so I hope this was the right decision. Anyway, thanks to every one who posted along the way, brace yourselves for some fairly uninformed posts on system design.
