Powerful and efficient, the Q-Mark MUH0521 electric unit heater comes with many features that make it versatile, safe and long lasting. It has a quality construction that ensures a longer useful life and includes many desirable upgrades that make it easy to use. It's the perfect heating solution for your warehouse, factory or other commercial spaces.

Sturdy Construction
The MUH0521 electric unit heater is designed to last because of cooler sheath temperatures and faster heat dissipation. It also features a rugged build with die-formed steel housing for additional structure.

Get Rid of Cold Drafts
With the Q-Mark MUH0521 electric unit heater, you'll no longer have to deal with cold drafts while your heater warms up since a fan delay feature won't disperse air until the heating element is warm.

Additional Safety Features
The Q-Mark MUH0521 unit heater features an automatic reset thermal cut-out for added protection from overheating.  It also meets all standards of OSHA and UL certifications for safety.

Advanced Design
The Q-Mark MUH0521 electric unit heater is designed to include an advanced pull-though air flow system that draws air across the heating element to operate at a cooler temperature and ensure even air distribution.
