I'm trying to make the decision between Tarm, EKO and Econoburn for a primary wood only system placed in a farm outbuilding and leave my oil forced air as backup in the house. I have a good handle on the tarms but the Eko does not show their heat exchanger setup very well in the diagrams that I have seen and the Econoburn does not show theirs at all. Does anyone have any of these systems setup near Hamilton, Guelph or Cambridge? Has anyone brought one across the border and did you pay duties or just PST and GST?
