Clean lines, gentle curves and modern technology meet with the AP5780E. This slim line pellet stove is designed to fit into tighter spaces yet produce the same amount of heat as a full-size pellet stove. It can heat up to 2,200 Sq. Ft. The all-digital control system comes with a temperature readout and a remote control for simple adjustments. It comes with a 46 Lb. Hopper to provide up to 32 hours of burn time between fillings. This stove is a showpiece with its curved black sides and flat black accents. Pellet heaters work by using a software driven control board to precisely deliver a pre-determined amount of fuel from the hopper into a burn chamber. An electric heating element, used only in a startup, heats the pellets until they ignite. The combustion blower forces air through the burn chamber, and once ignited, it provides active combustion of the pellets resulting in very little ash.
