Marley Q-Mark MUH152 Type MUH 3-Phase Electric Unit Heater, 208/240-Volt

The Marley Q-Mark MUH152 is a Type MUH 3-Phase electric unit heater engineered to deliver dependable, high-output heating for commercial and industrial spaces. This unit heater is rated 11.2-Kilo-Watt at 208-Volt or 15-Kilo-Watt at 240-Volt, drawing 31.3/36.1-Amp depending on supply voltage, giving installers the flexibility to match the heater to whichever electrical service is available on the job site. Because the MUH152 is rated for 3-Phase power, it is well suited to commercial and industrial buildings where 3-Phase circuits are already in place. Backed by the Marley Q-Mark name, the MUH152 is built to provide consistent, code-compliant performance in professional electric heating applications.

Key Features

  • 3-Phase Power Input: Designed for 3-Phase electrical service for balanced, efficient heating performance in commercial and industrial buildings.
  • Dual-Voltage Rating: Delivers 11.2-Kilo-Watt of heat output at 208-Volt or 15-Kilo-Watt at 240-Volt, so one unit heater accommodates two common supply voltages without needing a different model for each service.
  • Amperage Draw: Rated 31.3/36.1-Amp corresponding to the 208-Volt/240-Volt operating range, giving electricians the data needed for accurate circuit and breaker sizing.
  • Type MUH Configuration: Type MUH design built specifically for electric resistance unit heating in larger interior spaces.
  • Model MUH152: Clearly identified model number simplifies ordering, replacement, and parts matching for maintenance teams.
  • Q-Mark Product Line: Part of the Marley Q-Mark family of electric heating equipment.

Marley MUH152 – Frequently Asked Questions

1) Can the Marley Q-Mark MUH152 unit heater run on single-phase power?
No. The MUH152 is a 3-phase heater only. If the building only has single-phase service, this model will not work and you need a single-phase MUH unit instead. Confirm the panel feeding the space is 3-phase before ordering.
2) I am replacing an existing electric unit heater. What do I need to match to use an MUH152?
Two things decide it: the supply has to be 3-phase, and it has to be 208 or 240 volt. If the old heater was fed from a 3-phase 208V or 240V circuit, the MUH152 lines up on the electrical side, but check the existing circuit is rated for 31.3 amps at 208V or 36.1 amps at 240V. A 480-volt or single-phase existing feed rules this model out.
3) Is the Marley MUH152 a good fit for heating a warehouse or shop bay?
That is what it is built for. The MUH152 is an electric resistance unit heater aimed at commercial and industrial space heating, warehouses, garages, workshops, and supplemental heat in large interior areas. At 15 kW on 240-volt 3-phase it is a high-output unit rather than a small office heater.
4) What part number do I order for the Marley Q-Mark 15 kW 3-phase unit heater?
Order by model MUH152. That is the Marley Q-Mark manufacturer part number for the Type MUH 3-phase unit heater rated 11.2 kW at 208V or 15 kW at 240V, and it is the number maintenance teams should use for replacement and parts matching.
5) Will the Marley MUH152 work on 480-volt 3-phase service?
No. Even though the MUH152 is a 3-phase heater, it is rated 208/240 volt only. On a 480-volt service you would need either a different voltage model or a step-down transformer, so specify a 480-volt MUH unit instead.
