Issues with coal fired hydronic heating system
I have had a coal fired hydronic heating installed which I believe is performing below optimum. The installer believes that it is going as well as it can, but I am not convinced and based on my reading, I believe that the distribution system is incorrectly designed and plumbed. I am on my own to fix this so I am keen to learn more about hydronic heating. I have summarised the issues in an attachment and included some schematics and annotated photos of the system.
