How does the Qmark electric counterflow wall furnace operate?
This unit works by drawing cool through the exterior grille. The air is pushed downward toward the open coil electric heating element by a large fan blower. The warm air then circulates out through the bottom grille of the heater and warms the space through convection heating. The heater runs on a single-phase 240V line voltage and produces 9.2 kW of heat or 31,396 BTU/Hr.
