I just purchased this identical stove (the Harmon SF_250). I cannot seem to find a store to purchase the optional heat collector. I was hoping somebody could help me out. Thanks, Robert
You can try fisher stoves they been selling Harmon's been dealing with them for years and great people,
if there still making the heat collector they will be able to help you.
you can also go to a sheet metal /duct service they should be able to make the collector with no problems
