The only real Canadian manufacturers are Thermodynamics Ltd (Nova Scotia) and Enerworks (london Ont). Of the 2 Thermodynamics are the most honest IMHO. Viessmann had distribution in Vancouver and makes a good flat panel and a good Vacuum tube but for space heating, I would not look at tubes unless you had a lot of replacement tubes and a way to keep the panel temp below 100C most of the time.
TD will ship anywhere and sells container loads to Switzerland. It is my favorite panel for drainback and glycol systems.
There are no North American makers of Vacuum tubes. They are all imported from Germany or China.
