Marley CWH8 Wall Heater with Disconnect Switch, CWH1 Series
The Marley CWH1 series is a wall-mounted electric heater platform built for commercial and light-industrial interior spaces, offered in two model configurations — CWH1151DS and CWH1208DS — to match different branch-circuit supplies. Every CWH1 series heater includes a built-in disconnect switch, giving installers and maintenance crews a local means of de-energizing the unit for service or troubleshooting without returning to the branch panel. The CWH1208DS configuration delivers 2000W of heating output on a 208V supply, sized for offices, lobbies, entryways, classrooms, and similar interior spaces that need dependable supplemental or primary electric heat. As a Marley-branded product, the CWH1 series is built to the reliability standard electrical contractors expect from the CWH line.
Key Features
- Two Model Configurations: Available as CWH1151DS or CWH1208DS within the CWH1 series, letting contractors match the heater to the branch-circuit supply on site.
- Electrical Rating: The CWH1208DS configuration is rated 2000W at 208V for dependable commercial heating output.
- Integrated Disconnect Switch: A built-in disconnect switch lets technicians safely shut off power at the unit itself, simplifying service, filter changes, and troubleshooting.
- CWH1 Series Platform: Consistent design across the CWH1 series supports facility standardization across multiple installations.
- Wall-Mounted Form Factor: Mounts directly to the wall, keeping the heating unit out of walkways while directing warm air into the occupied space.

Marley CWH1151DS – Frequently Asked Questions
1) What is the difference between the Marley CWH1151DS and CWH1208DS wall heaters?
The two models in the Marley CWH1 series are matched to the branch circuit you have on site. The CWH1208DS is rated 2000W at 208V. The CWH1151DS is the other configuration in the series, ordered when the supply calls for it. Both carry the built-in disconnect switch, so the choice comes down to the voltage feeding the space rather than any difference in how the unit mounts or services.
2) Do I still need a separate service disconnect near a Marley CWH1 wall heater?
No. Every CWH1 series heater ships with a disconnect switch built into the unit, so a technician can de-energize it right at the wall for service, filter changes, or troubleshooting instead of walking back to the branch panel. That is what the DS suffix on CWH1151DS and CWH1208DS indicates.
3) Can I put a Marley CWH8 wall heater in a lobby or classroom, or is it only for utility spaces?
Interior occupied spaces are exactly what the CWH1 series is sized for. Marley lists offices, lobbies, entryways, classrooms, break rooms, retail entries, and mechanical or utility rooms. It mounts on the wall rather than sitting on the floor, which keeps it clear of walkways while it pushes warm air into the room. It is an interior commercial and light-industrial heater, so it is not intended for outdoor or exposed locations.
4) Is the Marley CWH1 a fan-forced heater or a radiant/convection unit?
It is a fan-forced electric wall heater. A blower moves air across the element and directs the warm air out into the occupied space, so you get faster pickup in an entryway or lobby than you would from a passive convector. If you are after silent operation in a space like a private office at night, a fan-forced unit is the wrong pick and a convection or radiant panel is the better choice.
5) Can I standardize a whole building on the Marley CWH1 series if the voltages differ floor to floor?
That is the practical reason the series exists in two configurations. The CWH1151DS and the 2000W, 208V CWH1208DS share the same CWH1 platform and the same integrated disconnect, so a facility can run one heater design across multiple installations and just specify the model that matches the branch circuit in each location. Maintenance crews learn one unit, and spares logic stays simple.
6) Will a 2000W Marley CWH1208DS heat a room on its own, or is it supplemental only?
Marley positions the CWH1 series for both supplemental and primary electric space heating, so the 2000W, 208V CWH1208DS can be the only heat in a small interior room or an assist in a larger one. Size it against the room's heat loss the same way you would any electric unit heater; 2000W is the output you are working with on that model.
7) What exact part number do I order for the 208V Marley wall heater with a disconnect?
The 208V unit is Marley part number CWH1208DS, rated 2000W. The companion model in the series is CWH1151DS. Both are CWH1 series fan-forced wall heaters with the disconnect switch built in.
