Marley Q-Mark 2578W Electric Baseboard Heater, Berko® 1-Phase, Navajo White

The Marley Q-Mark 2578W Electric Baseboard Heater is a Berko® 1-Phase baseboard heater engineered for reliable zone heating in a Navajo White finish. This multi-voltage unit delivers 2000 Watts at 277-Volt, 1504 Watts at 240-Volt, or 1128 Watts at 208-Volt, giving installers flexibility across common commercial and residential electrical systems. Its low-profile baseboard design allows for straightforward installation along walls for consistent, comfortable room heat without occupying floor space. This wattage flexibility makes the 2578W a practical choice for electricians and contractors who want to standardize on a single heater model across projects that run on different service voltages, reducing the number of unique parts carried on the truck.

Marley 2578W – Frequently Asked Questions

1) Can I use one baseboard heater model across a building with mixed 208V and 277V circuits?
Yes, that is the point of the 2578W. Because the element is rated at all three common voltages (277, 240, and 208), electricians can carry one model and install it wherever the branch circuit lands, instead of stocking a separate heater for each service voltage. Just remember the heat output drops as the voltage drops, so the room load calculation has to be done at the actual voltage.
2) Does the Marley 2578W baseboard heater come with a thermostat?
The 2578W is the heater housing and element only. Electric baseboard needs separate temperature control, either a wall-mounted line-voltage thermostat for the zone or a built-in end-mount thermostat kit ordered as an accessory. Decide which before rough-in, because a wall stat needs its own box and conductors run to it.
3) Is the Marley 2578W baseboard heater single phase or three phase?
Single phase. The 2578W is a 1-phase unit wired off a standard branch circuit. If your panel is a three-phase service, you are still landing this on a single-phase, two-pole circuit derived from it, which is the usual case for the 208V rating.
4) What part number do I order for the Marley Q-Mark Berko baseboard heater in Navajo White?
Order Marley manufacturer part number 2578W. It is the Q-Mark Berko 1-phase baseboard in Navajo White with the 2000W/277V, 1504W/240V, 1128W/208V element. There is a single configuration under that number, so no suffix or finish code to add.
5) Is the Marley 2578W suitable as the only heat source in a room, or just supplemental?
Either, depending on the load. The 2578W is used for full residential room zone heating and for commercial supplemental space heating, including offices, classrooms, and common areas. For primary heat you size total baseboard wattage to the room's heat loss, and on a 208V circuit you only get 1128 watts out of this unit, so a larger room may need two.
6) What color is the Marley Q-Mark 2578W baseboard heater housing?
Navajo White, which is the off-white Q-Mark baseboard finish. It reads neutral against most painted walls and white trim, so for a property manager replacing one unit in a run of existing Q-Mark baseboard, the new housing will match the rest of the line rather than standing out as bright white.
7) Where can I get the wiring and mounting instructions for the Berko 2500 Series baseboard heater?
Marley publishes a Berko 2500 Series baseboard submittal sheet for the dimensional and electrical data, plus a separate installation, operation and maintenance instruction document, and the heater also appears in the Q-Mark digital catalog. Pull the submittal sheet for the layout and the IOM for the wiring and clearance requirements before you set the unit on the wall.
