Marley Q-Mark CZ2048T COS-E Zone Fan-Forced Wall Heater
The Marley Q-Mark CZ2048T is a COS-E™ zone fan-forced wall heater engineered for dependable, dual-voltage spot heating in commercial and residential spaces. This unit delivers 2000/1000-Watt heat output at 240-Volt or 1500/750-Watt at 208-Volt, drawing 8.3/4.2-Amp on a 240-Volt circuit, giving installers flexible two-stage heating to match whatever circuit is available on the job. Built as a wall-mount zone heater, it pairs fan-forced air delivery with Marley's Q-Mark COS-E™ engineering for consistent, reliable comfort in offices, retail spaces, utility rooms, and other areas where full ducted HVAC coverage is not practical. The dual power settings let the same unit serve as a primary or supplemental heat source depending on the space.
Key Features
- Dual-Voltage Wattage: Rated 2000/1000-Watt at 240-Volt or 1500/750-Watt at 208-Volt, so the same heater can be wired to either common branch-circuit voltage without a change in model.
- Amperage Draw: 8.3/4.2-Amp at 240-Volt for straightforward, code-compliant circuit sizing and breaker selection during rough-in.
- Fan-Forced Heating: A forced-air design circulates warm air across the space rather than relying on passive convection, delivering faster, more consistent zone comfort.
- Two-Stage Output: High and low wattage settings at each supported voltage let installers or end users dial in output to match the size of the space and the season, rather than running a single fixed heat level.
- COS-E™ Series Engineering: Part of Marley's Q-Mark COS-E™ line of zone wall heaters, built specifically for dependable fan-forced spot and zone heating duty.
- Wall-Mount Configuration: Designed as a wall-mounted zone heater rather than a ducted or ceiling unit, simplifying installation in rooms without existing HVAC runs.
- Flexible Voltage Compatibility: Supporting both 240-Volt and 208-Volt supply, the CZ2048T fits a wider range of building electrical services without requiring a different heater model for each voltage.

Typical Applications
- Commercial and Residential Zone Heating
- Supplemental Spot Heating in Offices, Retail, and Utility Spaces
- Wall-Mount Installations Where Ducted HVAC Is Impractical
- Mixed-Voltage Buildings Requiring 240-Volt or 208-Volt Compatibility
- New Construction and Retrofit Heating Upgrades
Why Marley?
Marley's Q-Mark COS-E™ line brings dual-voltage flexibility and fan-forced performance to zone heating applications where dependable, accurately rated output matters on the job. With clearly stated wattage and amperage figures across both 240-Volt and 208-Volt circuits, the CZ2048T gives electricians and facility managers a straightforward, predictable heating solution instead of guesswork at install time. Choosing a Marley Q-Mark heater means specifying equipment built around a defined, dual-voltage performance profile rather than a single-voltage unit that may not match the circuit actually available in the space.

Marley CZ2048T – Frequently Asked Questions
1) Can the Marley Q-Mark CZ2048T wall heater run on a 208V circuit, or does it need 240V?
Either. The CZ2048T is a dual-voltage unit rated 208/240V. On 240V it puts out 2000/1000 watts; on 208V the same heater delivers 1500/750 watts. No model change or kit is needed to move between the two, so one part number covers both common branch-circuit voltages in a mixed-voltage building.
2) What size breaker and circuit do I need for a CZ2048T heater?
The CZ2048T draws 8.3/4.2 amps on a 240V circuit, the high setting being 8.3A. Size the branch circuit and overcurrent protection to that load per the NEC rules for fixed electric space heating, which require the circuit be rated at 125 percent of the heater's load. On 208V the heater's output drops to 1500/750 watts, so current draw drops proportionally.
3) What is the difference between a fan-forced wall heater like this and a convection or baseboard heater?
Fan-forced means a blower pushes air across the heating element and out into the room, so warm air is distributed actively instead of rising off the element by natural convection. The CZ2048T is a fan-forced wall unit, which gets a cold room up to temperature faster and spreads heat more evenly than a passive convector of similar wattage. Baseboard convection is quieter and better suited to continuous low-level heat along an exterior wall; a fan-forced wall heater is the choice for a single zone that needs quick recovery, like an entry, restroom, or utility space.
4) Can I install the CZ2048T in a room with no ductwork?
That is what it is for. The CZ2048T is a wall-mount zone heater, not a ducted or ceiling-mounted unit, so it only needs a wall location and a 208V or 240V branch circuit. That makes it a common pick for retrofit work in offices, storage and utility rooms, and additions where extending ducted HVAC is impractical.
5) If I am standardizing wall heaters across a building with both 208V and 240V panels, does this save me stocking two models?
Yes. Because the CZ2048T is rated for 208/240V in one unit, a property manager or MRO buyer can carry a single part number for openings fed from either service. Output differs by voltage (2000/1000W at 240V, 1500/750W at 208V), so plan the heat load per room by which panel feeds it, but the hardware on the shelf is the same.
6) Where do I find the rough-in and wall opening dimensions for the Q-Mark CZ2048T?
The can dimensions, wall cavity requirements, and mounting detail are in the Q-Mark COS-E Zonal Wall Heater submittal sheet and the installation, operation and maintenance instructions, both published with the CZ2048T. Pull the submittal before framing or cutting in, since the heater housing has to match the cavity and the required clearances around it.
7) Is the CZ2048T one model or do I have to pick a configuration when ordering?
It is a single configuration, ordered as Marley Q-Mark manufacturer part number CZ2048T in the COS-E series. There is no separate voltage or wattage variant to select because the dual-voltage rating is built into the one unit.
