Description

QMark® MUH 208/240V Electric Unit Heaters are ideal as garage, shop or warehouse heaters. They can be used for primary, supplementary, dual-system or spot heating. The advanced air flow design of this QMark® MUH Electric Heater draws air across the element for even air distribution. The specially designed venturi allows for added air throw.

Applications: Factories, Warehouses, Garages, Stores, Shipping Rooms, Power Stations, Aircraft Hangers

Features/Advantages:

  • Mount horizontally or vertically
  • Completely enclosed fan motor
  • Optional control kits are field installable, increasing MUH adaptability to the specification market
  • Summer fan kits are available to adapt heater into a cooling fan
  • Heavy-gauge die-formed steel housing. Front and back is a neutral grey, the wrap-around steel section is a statuary bronze color
  • Ruggedly built, yet lighter weight for easier installation. No piping flues, valves or traps
  • Advanced pull-through air flow design draws air across the heating element for more even air distribution and cooler element operation
  • Specifically designed ventrui outlet to meet that added throw as required in a vertical position
  • Individually adjustable discharge louvers to control air flow
  • 1- or 3-phase wiring on 5-10 kW 208/240V and 15 kW 208V units (field interchangeable)
  • Aluminum-finned, copper clad steel sheath heating element has a longer life because of cooler sheath temperature and faster heat dissipation
  • Fan delay feature eliminates cold drafts. Element heats up before fan cuts in, then fan continues to distribute heat after element shuts off
  • 24V control transformer standard on most models, providing a safer and more accurate means of temperature control. 3 kW and 5 kW, 208-277V, have line voltage controls as standard
  • Automatic reset linear thermal cut-out, capillary type, provides protection over entire length of element areas
  • Meets all UL, NEC and OSHA requirements

    Super Heater

    Review by on Feb 2, 2015

    Installed the 7.5KW Q-Mark in my oversized 3 car garage. The heater works fantastic love having a seperate thermastat in the wall instead of climbing up to the heater.

    Excellent product

    Review by on Nov 26, 2014

    I installed 2 of the 7.5 KW Q-mark heaters temporarily in our church sanctuary and one in the fellowship hall after the boiler unexpectedly went down for an extended period of repairs just as the weather turned colder. They kept the areas comfortable without undue fan noise interrupting the service.

    The Heat Is On!

    Review by on Oct 2, 2009

    I always wanted a heated garage so when I built my new home 3 years ago I researched several electric heaters because my area of town does not offer natural gas. I purchased a QMark heater from QC Supply along with the ceiling bracket and a wall mounted thermostat. The heater works awesome and I even am able to hand wash my cars inside the garage during the winter months. It is so quiet that I can even run a TV without blaring the sound. I love it. I highly recommend the mounting bracket because otherwise it would be difficult to hang by itself.

    Great heater for the shop

    Review by on Oct 2, 2009

    I put a Q-Mark in my shop and very happy with it. Keeps the shop warm and is quiet and seems very energy efficient.

    This is an excellent unit for the money!

    Review by on Sep 8, 2009

    I really like my 7.5 kw Q-mark heater in my over sized 2 car garage. This unit might be a little big for my area but I like to maintain a 40-45
