Advanced Design
The Q-Mark electric heater is designed to draw air across the heating element with an advanced pull-though air flow system. This allows the heating element to operate at a safer, cooler temperature.

Sturdy Construction
The MUH0521 electric unit heater features cooler sheath temperatures and faster heat dissipation with an enclosed fan motor and a rugged die-formed steel housing. These ensures long operational life.

Get Rid of Cold Drafts
The Q-Mark MUH0521 electric unit heater has a fan delay feature to prevent cold drafts before your heater warms up. You can also control air flow with the adjustable air output louvers.

Convenient Mounting Features
Designed to be lighter, the Q-Mark MUH0521 unit heater doesn't have piping flues, valves or traps so that installation is hassle-free. The unit can be mounted vertically or horizontally for added convenience.
