Wall & Ceiling Heater for Commercial Spaces
The Q-Mark MUH0381 is a new electric unit heater rated for 208V AC single-phase power. It delivers 3.0 kW output and 10,200 BtuH capacity for warehouses, workshops or retail areas. Fan-forced operation pushes 350 cfm with a 27°F temperature rise and a 12 ft horizontal air throw.
Mounting Flexibility and Electrical Needs
Units install on ceilings or walls using the beige polyester powder-coated housing that measures 16 in high by 14 in wide and 7 1/2 in deep. The mechanical selector dial provides on-board control while the internal contactor coil runs on the same 208V supply. Installation requires a circuit capable of 14.5 A at 60 Hz.
Thermal Output and Operational Sound
Fan-forced design moves heated air across the rated throw distance to maintain setpoint. The 3.0 kW element and 350 cfm blower create measurable airflow noise typical of commercial unit heaters. Power draw holds at the rated amperage during active heating cycles.

Questions about this item
How long can the heater run continuously before the 27-degree temperature rise hits its limit?
The unit delivers a 27-degree Fahrenheit air temperature rise at 350 cfm airflow; sustained operation is limited by the mechanical selector dial and 208V contactor coil, which cycle power to maintain safe output.
What noise and heat levels should I expect when the 3.0 kW unit runs all day?
Fan-forced operation moves 350 cfm with a 27-degree rise, producing moderate airflow sound and surface heat from the beige polyester powder-coated housing during continuous use.
What electrical circuit must already be in place for this 208V, 14.5A heater to work?
A dedicated 208V AC, single-phase, 60 Hz circuit rated for at least 14.5 amps with a compatible mechanical selector dial control is required for installation.
