Marley CWH1202DSF Contemporary Commercial Fan-Forced Wall Heater, 1-Phase

The Marley CWH1202DSF is a Contemporary Commercial Fan-Forced Wall Heater engineered for reliable supplemental heating in commercial and light-industrial spaces. Part of the Q-Mark line from Marley, this 1-Phase wall heater delivers dual power settings of 2000/1000-Watt at 240-Volt or 1500/750-Watt at 208-Volt, producing 6826/3413 BTU/Hour at 240-Volt and 5120/2560 BTU/Hour at 208-Volt output. With an amperage draw of 8.3/4.2-Amp depending on the selected heat setting and supply voltage, the CWH1202DSF is built to provide flexible, dependable heating performance across a wide range of commercial installations where either 208-Volt or 240-Volt service is available.

Key Features

  • Dual Wattage Settings: Operates at 2000/1000-Watt on a 240-Volt circuit or 1500/750-Watt on a 208-Volt circuit, giving installers flexible heat output to match the job.
  • BTU Output: Delivers 6826/3413 BTU/Hour at 240-Volt and 5120/2560 BTU/Hour at 208-Volt, so heat capacity scales automatically with the available branch circuit voltage.
  • Amperage Draw: Rated at 8.3/4.2-Amp depending on the active heat setting and supply voltage, simplifying circuit sizing during specification.
  • 1-Phase Configuration: Designed for standard 1-Phase commercial electrical service, keeping installation straightforward for licensed electricians.
  • Fan-Forced Heating: Fan-forced operation circulates warm air throughout the space for consistent, even heating rather than relying on passive convection alone.
  • Contemporary Commercial Design: Styled for commercial environments where both appearance and heating performance matter to the space.
  • Wall-Mounted Configuration: Compact wall-mounted form factor suited to offices, restrooms, entryways, and other zoned commercial areas.

Why Marley?

Marley's Q-Mark line of wall heaters is engineered to deliver dependable, flexible heating for demanding commercial environments. The CWH1202DSF's dual-voltage, dual-wattage design lets electrical contractors match heat output to whichever 208-Volt or 240-Volt circuit is available on site, without swapping equipment or reworking the branch circuit. That same dual-rated 1-Phase design also simplifies specification, since a single model covers both common commercial voltages and both a high and low heat setting. Choose Marley for commercial-grade, fan-forced wall heating built for consistent, professional performance in offices, restrooms, and other zoned commercial spaces.

Marley CWH1101DSF – Frequently Asked Questions

1) Will the Marley Q-Mark CWH1 wall heater work on a 208V circuit, or does it need 240V?
Both. The CWH1 Series is dual rated for 1-phase 208V or 240V service, and the output follows the voltage you feed it. On the CWH1202DSF you get 2000/1000W at 240V and 1500/750W at 208V. No parts swap or rewiring of the branch circuit is needed to move between the two, which is why one model covers both common commercial voltages.
2) What size breaker and conductors do I need for a 2000W Q-Mark CWH1202DSF heater?
The CWH1202DSF draws 8.3/4.2A depending on the heat setting and supply voltage, so the high setting is the one to size for at 8.3A. Your electrician sizes the branch circuit off that figure per local code; it's a 1-phase load.
3) What's the difference between the CWH1101DSF and the CWH1202DSF?
Output only. The CWH1101DSF is the 1000/500W unit and the CWH1202DSF is the 2000/1000W unit. Both are Q-Mark CWH1 Series contemporary commercial fan-forced wall heaters with a disconnect switch, 1-phase. Pick the 1000W for a restroom or small entry vestibule and the 2000W for an office or larger zone.
4) Does the CWH1 heater come with a disconnect switch, or do I have to add one?
A disconnect switch is built into the CWH1 Series units (the DSF suffix on both CWH1101DSF and CWH1202DSF). That gives the electrician a means of disconnect at the heater itself rather than running back to the panel to service it.
5) How much heat will a 2000W electric wall heater actually put out in BTU?
The CWH1202DSF produces 6826/3413 BTU/hour on 240V and 5120/2560 BTU/hour on 208V, high and low setting respectively. Use the lower pair if the available service is 208V, because the same heater derates on that voltage and a sizing calculation done at 240V will come out optimistic.
6) Can I use the Q-Mark CWH1 as the only heat source for a room?
No. The CWH1 Series is a supplemental and zone heating product, intended for spaces like offices, retail areas, restrooms and entryways alongside a primary system. For a space with no other heat, size a primary system rather than relying on a 1000W or 2000W wall unit.
7) Can I standardize on one Marley wall heater model across a building with mixed 208V and 240V panels?
That's the main reason to spec the CWH1 Series. Because each unit is rated for both 208V and 240V 1-phase, one model number covers openings fed from either panel, and each unit still has a high and low setting on site. For a mixed-voltage facility you only have to decide between the 1000/500W CWH1101DSF and the 2000/1000W CWH1202DSF based on room size, not on voltage.
8) Is a fan-forced wall heater better than a convection one for a restroom or entryway?
For those spaces, yes. Fan-forced operation moves warm air out into the room instead of letting it stack at the ceiling, so you get faster recovery and more even temperature in a small, frequently opened space like a restroom or vestibule. Passive convection units are quieter, which matters more in a private office or a guest room where fan noise is a complaint.
9) Is the Marley CWH1 a 3-phase heater?
No, the CWH1 Series units here are 1-phase, built for standard 1-phase commercial service. If the only feed available at the location is 3-phase, this is not the right unit for that circuit.
