Keystoker stoves were designed by two electrical engineers that saw the need for a way to conveniently burn anthracite coal, which was plentiful, but heating with coal had a bad reputation of being dirty and requires maintenance several times a day.  Keystoker engineers developed an automatic stoker unit equipped with a coal hopper that held enough fuel for several days. This allowed the coal to be cleanly burned and without frequent maintenance. They then saw the need to designs stoves, furnaces and boilers to burn coal and built them in multiple sizes to meet our customers’ needs.
