I want to purchase a Greenwood Hydronic Wood Boiler to heat our home via forced hot water. I am trying to be thorough in my research before I purchase and am tossing out broad questions being ignorant and all. This will be a stand alone unit with no backup and will only serve for baseboard heating. I am looking at 4zones, possibly 5. Are there any opinions out there as to whether this should be a closed or open system? I don't know the pros/cons of either. I assume you need a circ pump for each zone? This unit comes shipped with a Taco 007 and honeywell aquastats. I read in this forum that folks have not been impresed with the technical support of either company but that doesn't tell me about the quality of the components. Any advise/wisdom on pitfalls to avoid? Any personal experiences with Greenwood?
I'd appreciate any input.
