The Marley Q-Mark MWUH5004 is a horizontal/downflow electric unit heater engineered for dependable space heating in commercial and industrial environments. This multi-tap unit heater delivers 1875/2500/3123/3750-Watt output at 208-Volt or 2500/3332/3750/5000-Watt output at 240-Volt, giving installers flexible field-selectable capacity to match the connected supply voltage. Finished in Beige, the MWUH5004 mounts horizontally or in a downflow orientation for versatile placement in the space being conditioned. As part of the Marley Q-Mark unit heater line, it is built to provide consistent, code-compliant electric heat for professional installations.

Marley MWUH5004 – Frequently Asked Questions

1) Can the Marley Q-Mark MWUH unit heater run on either 208V or 240V supply?
Yes. The Q-Mark MWUH horizontal/downflow electric unit heater is rated 208/240V and is field-configured for whichever service it lands on. On the MWUH5004 that means 1875/2500/3123/3750 watts at 208V, or 2500/3332/3750/5000 watts at 240V. One unit covers both, so a contractor working mixed-voltage buildings doesn't have to stock two part numbers. Note the nameplate 5000W rating is the 240V figure; on 208V the top tap is 3750W.
2) What wattage sizes does the Marley Q-Mark MWUH electric unit heater come in?
Two: the MWUH5004 at 5000W and the MWUH7504 at 7500W. Both are the same horizontal/downflow cabinet on 208/240V service, so the choice is purely about how much heat the space needs. Because the wattage is multi-tap and field-selectable, a larger unit can also be dialed down at install rather than swapped out.
3) I'm on 208V power. Will a Marley MWUH5004 still give me 5000 watts of heat?
No. On a 208V service the MWUH5004 tops out at 3750W; the 5000W figure is the 240V rating. If you need closer to 5000W of actual output on 208V, step up to the MWUH7504 and set the taps accordingly. This is the single most common sizing mistake on multi-voltage electric unit heaters.
4) Can this Marley unit heater be mounted pointing straight down from the ceiling?
Yes. The MWUH is a horizontal/downflow unit heater, so it can throw air horizontally across a space or be set to discharge downward from an overhead mount. That covers the two usual layouts in a warehouse bay, shop, or mechanical room where floor space is committed and the heater has to live overhead.
5) Do I need gas piping or a flue for the Marley Q-Mark MWUH heater?
No. This is an electric unit heater, so there is no gas line, no combustion air, and no venting. All it needs is a properly sized 208V or 240V circuit. That is why it gets used in retrofits and utility spaces where running gas and a flue isn't practical.
6) Is the Marley MWUH a multi-tap heater I can adjust in the field?
It is. Rather than a single fixed output, the MWUH5004 offers four selectable wattage steps on each voltage, so the installer trims capacity to the actual heat loss of the space at start-up instead of ordering a different model. Useful when the load calc changes between design and install, or when the same heater is being specified across rooms of different sizes.
