I live in Western NY, am new to this website, forum, and central heating with wood (my wife and I have years experience heating and cooking with wood stoves--- old hippies). I will have a wood/coal system for next season and invite offers for a smaller wood/coal boiler that any of you may have to sell. I have acquired a 500 gallon milk bulk tank to use for heat storage and am wondering if the bunch of old and new baseboard fin tubes that I have in the cellar would be suitable as the basis for my HX. Thanks to all of you for my education so far.
