Murray Heating System Patent
Here is the patent for an interesting piping system, offered by the Murrays, father and son. Gerry Gill, who found and shares this with us, comments, "This patent lists both the father and the son, so the heating system patent was the son's work, but both must have worked together on heating because they have many patents, but all seem to be within the same 15-year range. I like the induced chimney effect on their radiators." We do too!
