300 W Carbon Heating Plate for Walls and Ceilings
The 48 V surface heating system for integration into gypsum fiber dry lining boards – particularly practical for suspended ceilings and new interior fit-outs.

The Rebotherm carbon heating plate combines a gypsum fiberboard with a carbon heating surface on the back. It is designed for installation in suitable drywall constructions and emits heat via the room-facing surface.

Heating and drywall panel in a single component
A carbon heating plate is a gypsum fiberboard with an integrated electric heating surface. It is installed in a suitable wall or ceiling construction and emits heat via the finished room-facing surface.
Before installation, the plate presents as a manageable drywall element with pre-assembled electrical connection wires. In the finished wall or ceiling structure, the gypsum fiber side always faces the room, while the carbon heating surface is directed towards the wall or structural ceiling at the rear.

Advantages in Drywall Construction
Four specific properties resulting from the design and planning of the carbon heating plate.
Integrated into Drywall
The plate combines the gypsum fiber carrier and the rear heating surface in one element. It can be integrated into suitable wall and ceiling constructions.
Design Walls Freely
The heating surface is concealed behind the room-facing surface. With a suspended ceiling, the heating surfaces remain clear of furniture; the wall design depends on the chosen surface finish.
Room-by-Room Control
Separately controlled rooms each require a thermostat. The control box design depends on the total output and the zones.
Without Water-Bearing Heating Pipes
The plate operates with 48 V DC and a matching control box. The required mains connection and all protective measures belong in the hands of a qualified electrician.
How the Carbon Heating Plate is Installed
Four structured installation steps from planning to the finished ceiling or wall surface.
Step 1
Plan Heating Surfaces and Substructure
Precisely coordinate plate positions, room-by-room heating output, and cable routes in advance.
Step 2
Mount and Connect Heating Plates
Insert into the suitable substructure and make the connections according to the Rebotherm installation instructions.
Step 3
Check Function and Close Remaining Surfaces
Check the heating function before final closing and complete the remaining areas with suitable drywall panels.
Step 4
Finish Joints and Surface
Processing according to the specifications of the manufacturer of the gypsum fiberboards used and recognized technical rules.
Note: The Rebotherm installation instructions govern the product-specific mounting and electrical connection. Joint and surface treatment depend on the specifications of the board manufacturer and the material system used. According to the installation instructions, a maximum of four heating plates or 1,200 W are intended per suitable supply line; the specific cable routing and design is handled by a qualified electrician.

Ihre Räume. Ihre Heizplatten.
Wie viele Heizplatten brauchen Sie?
Dämmstandard auswählen, Räume hinzufügen und den voraussichtlichen Plattenbedarf ermitteln. Übernehmen Sie Ihre Planung anschließend direkt in den Shop und wählen Sie dort das passende Zubehör aus.
Ihr voraussichtlicher Heizplattenbedarf
| Raum | Fläche | Richtwert | Heizplatten |
|---|
ACHTUNG! Sehr hoher HeizbedarfBei dem gewählten Dämmstandard ist mit einem sehr hohen Heizenergiebedarf und entsprechend hohen Stromkosten zu rechnen.
Wir raten ausdrücklich von der Installation als alleinige Raumheizung ohne vorherige Verbesserung der Dämmung ab.
Bitte lassen Sie zuerst die Dämmmöglichkeiten und die tatsächliche Heizlast prüfen. Wir unterstützen Sie gerne bei der Planung einer geeigneten Dämmung.
Ihre Plattenanzahl und Raumaufteilung werden direkt in den Shop übernommen. Dort können Sie Ihre Planung prüfen und die passende Stromversorgung sowie Raumthermostate auswählen. Weitere Anschlussleitungen und Montagezubehör berücksichtigen Sie gemäß Installationsanleitung.
Planung in den Shop übernehmenDie Übernahme löst keine Bestellung aus. Sie prüfen Ihre Auswahl im Shop und legen sie anschließend selbst in den Warenkorb.
Für Ihren Bedarf von mehr als 100 Heizplatten erstellen wir Ihnen ein individuelles Angebot. Senden Sie uns Ihre Raumübersicht und gerne einen Grundriss.
Individuelles Angebot anfragenDie Berechnung liefert eine Orientierung und ersetzt keine raumweise Heizlastberechnung. Fenster, Raumhöhe, Außenflächen, Standort und Wunschtemperatur können den tatsächlichen Bedarf verändern. Prüfen Sie auch die verfügbare Montagefläche: Eine ganze Platte benötigt 1,5 m² Wand- oder Deckenfläche. Den Netzanschluss übernimmt eine Elektrofachkraft.
Frequently Asked Questions about the Carbon Heating Plate
Important answers regarding drywall installation, accessories, control, and energy consumption.
Can I use the heating plate on a suspended ceiling?
Yes, with a suitable and load-bearing drywall substructure. Installation is carried out according to the product-specific instructions.
Is the heating plate visible after installation?
After suitable joint and surface treatment, the gypsum fiber side forms part of the finished wall or ceiling.
What accessories do I need?
A matching control box with 48 V output, room thermostats, and required connection or installation materials. The scope depends on the project.
How many thermostats do I need?
One per separately controlled room.
Can one control box supply multiple rooms?
Yes. Total output and separate control zones must match the room layout.
Can I install it myself?
Manual work is possible with appropriate specialist knowledge and compliance with the instructions. The mains connection and required electrical tests are handled by a qualified electrician.
How high is the power consumption?
A heating plate with 300 W converts 0.3 kWh of electrical energy in one hour of continuous operation. Power supply losses are additional. Annual consumption and heating costs depend primarily on the building, weather, desired temperature, and usage.
Can I order more than 100 heating plates?
Yes, via individual planning and a personal quote from Rebotherm.
Are you planning a fit-out or a larger heating project?
Send us a floor plan, the room areas, and information on the insulation status. Together we will clarify the required heating surfaces, the room control, and the matching accessories.
