Hi, does any one out there remember the Electrend Electric wall heater from the 60’s?  It was a heater mounted in the wall with a duct connected to it and the duct went up the wall to near the ceiling with a grill on the opening.  It drawed hotter air from the ceiling and sent it through the duct into the heater and was more efficient than baseboard or other type wall heaters.  I am trying to find a used one or new one.  Maybe someone out there has one they haven’t used or knows a supplier that never sold there entire stock. All help will be apppreciated.  Thanks – Larry
