Sand and Graphit infrared panels

Two colours, a considered choice

Sand and Graphit infrared panels for your interior

Sand and Graphit are two colour versions of our metal panel range. Sand gives you a sand-coloured front; Graphit has a dark, graphite-coloured appearance. Both have a silk matt finish. This creates a different impression from a white metal sheet or glossy glass surface. Colour makes the panel part of the interior, while required output is determined separately.

With Sand and Graphit infrared panels, you can choose to blend quietly into the wall or create a visible contrast. What works pleasantly depends on light, surrounding materials and where you want to mount the appliance. A dark wall with a dark panel creates a different impression from the same panel against a light background. Assess colour in relation to the room.

The product names Sand and Graphit identify these versions’ colours. On this page, we also use sand-coloured and graphite-coloured to describe the shades. We do not assign an assumed RAL number to them. If you have a specific RAL colour number for your interior, compare the separate metal RAL versions. A similar name or on-screen colour is insufficient to confirm an exact colour match.

You need not adapt the entire interior to the heating. Start with the available mounting position and desired material appearance. We then compare which panel size fits and how the chosen output belongs in the heating plan. This keeps colour selection connected to a product that also suits your application technically.

Four models: two outputs per colour

The 2026 product catalogue divides Sand and Graphit infrared panels into four articles. For Sand, these are PBSA0710 and PBSA0910. For Graphit, they are PBMG0710 and PBMG0910. At corresponding outputs, both colours have the same external dimensions and stated weight. You therefore first compare the dimensions and output needed, then select the suitable colour version.

The 710-watt models measure 59.2 × 119.2 × 1.7 cm and weigh 14 kg. At 910 watts, dimensions are 59.2 × 149.2 × 1.7 cm and weight is 17 kg. The larger version is therefore longer and heavier. Check not only whether the panel visibly fits the wall or ceiling, but also whether the available supporting surface and fixing space are suitable for that article.

Colour changes the model code. PBSA0710 and PBMG0710, for example, are separate articles despite sharing output, dimensions and weight. Specify the complete code in an enquiry. Saying only that you want a 710-watt panel does not identify the chosen colour. For several rooms, an overview of article numbers, quantities and intended appliance positions helps.

The two product tables above show the data for each colour. Table values form the starting point for technical comparison. They do not provide definitive advice on the output required for a particular room. For that, we include heating demand and positioning. You can select the desired version directly in the product catalogue or ask us to assess it with you first.

Assess colour, room and use together

Choosing Sand and Graphit infrared panels starts with the room where you want to experience warmth. In a living room, the finish can complement wood, light walls or a dark accent. In a study, available wall or ceiling space may instead be the main starting point. We connect this design choice with daily use: when are you present and where do you want comfort?

A photograph helps assess the interior but does not show every technical condition. Also provide room dimensions, ceiling height and information about windows and insulation. Specify existing heating and whether it will remain in operation. These details let us distinguish supplementary warmth from a plan in which panels have a greater heating role.

In a home with several rooms, you need not use the same colour everywhere. You can select Sand or Graphit per room when the available models suit the plan. Temperature controls and appliance quantities are likewise determined for each situation. A uniform appearance is no reason to give a room an inadequate or unsuitable model.

Want to see the colour first? Use our dealer page to find a suitable showroom or partner and arrange beforehand which versions are available. Not every location displays every article. A visit helps assess the finish; output selection remains a separate part of the advice. For initial orientation, also explore our guide to designer heating in the interior.

710 or 910 watts: what does your room need?

With Sand and Graphit infrared panels, do not select output according to colour or floor area alone. Heat loss through the building envelope, ventilation, glazing area and desired indoor temperature matter. Two rooms with the same floor area can have different heating demands. How you use the room also matters when comparing primary or supplementary heating solutions.

The 910-watt version draws more power than the 710-watt version, but is not automatically the best choice for every room. We examine the output required by the heating plan and how it can be distributed across available mounting positions. A suitable appliance combination may distribute heat differently from one panel in a less suitable position.

The catalogue gives an indicative room area of 10 to 14 m² for the 710-watt models and 13 to 18 m² for the 910-watt models. Use these values solely for orientation. They are not a guarantee for every room and do not replace an assessment of insulation, use and heat loss. Mention differing conditions, such as extensive glazing or a high ceiling, in your enquiry.

Our guide to calculating heating output explains which data support selection. You need not establish every result yourself beforehand. Start with the room and your heating objective. We discuss what further information is needed for the proposal and which combination of output, dimensions and positioning suits it.

Prepare wall and ceiling mounting

Sand and Graphit infrared panels offer wall and ceiling mounting options according to model instructions. On a wall, the colour can visibly complement the interior. Ceiling mounting leaves wall space free for furniture and other uses. The right position follows from heat distribution and the available supporting surface; a suitable colour and external dimensions alone do not constitute complete mounting preparation.

The panels have a metal front, ESHC Plus heating technology and rear insulation. The described metal construction includes two integrated thermal safety switches. This construction does not permit arbitrary fixing or positioning. Check the prescribed clearance, fixings and connection for the specific article. The weight of 14 or 17 kg also belongs in the assessment of the mounting surface.

For a ceiling arrangement, specify the ceiling construction and where the panel will be positioned relative to occupied locations. On a wall, we consider furniture, doors and windows. Obstacles can affect heat distribution. With a floor plan or photographs, we can discuss the starting points before selecting the appliance or preparing its fixings.

Select a lighting frame, recessed frame or stand solely on confirmed compatibility with the relevant model. Compare our infrared panel accessories and identify the desired component in your enquiry. Information about panel positioning helps develop the placement decision. During final installation, your article’s instructions remain decisive.

Precon and temperature controls for these versions

Current Sand and Graphit infrared panels have a 650 mm connecting cable with the precon plug system. When selecting panels, we also choose suitable temperature controls. For these versions, the product catalogue states that a controller must be added to meet the relevant ecodesign requirements. We therefore include controls and required components in the proposal from the outset.

A complete combination includes the panel and suitable controls, with the correct receiver or connecting components for the chosen version. Model codes matter when expanding an existing system. Matching plug shapes do not prove that arbitrary control series work together. If unsure, send details of the existing panel and thermostat or receiver used.

We also discuss room use and where temperature is measured. A weekly programme, separate control per room or operation with additional equipment may be relevant, depending on the selected control series. Wi-Fi is not a general built-in feature of every panel. Available controls follow from the complete arrangement confirmed for your installation.

When combining several appliances, we check electrical load against control component capacity. Panel quantity alone does not establish how the combination should be connected. Read our explanation of precon and connections and explore available thermostats and controls. You can then specify control preferences before selecting a version.

Protection rating and differences from other panels

Sand and Graphit infrared panels have an IP21 protection rating and protection class I. These details matter for application and electrical preparation. A dark or sand-coloured metal front does not automatically make the appliance suitable for every humid room or outdoor environment. Check the conditions and permitted positioning of the specific article.

For bathrooms, we offer separate metal bathroom panels. The BKW Plus family combines room heating with its own zone for appropriate towel drying and has its own technical characteristics. This is a different product selection from Sand and Graphit on this page. Similar colour or external dimensions do not prove that heating functions and mounting requirements are identical.

A glass front also has a different material appearance and construction. If selecting primarily for a dark finish, compare not just the shade but also available output, weight and intended function. A chalkboard panel or mirror, for example, is more than a colour alternative. Its surface has a separate use that must fit the application.

The infrared panel overview helps distinguish these product families. If you mainly want to compare metal construction, explore our white metal PB panels. They offer a wider range of dimensions and outputs. We help determine whether Sand, Graphit or another family better suits the combination of appearance and technical requirements.

Calculate electricity consumption for Sand and Graphit

For Sand and Graphit infrared panels, calculate electricity consumption from output and actual operating time. A 710-watt model operating at full power for two hours in an example uses 1.42 kWh. At 910 watts for the same operating time, consumption is 1.82 kWh. Multiply the energy quantity by your own electricity tariff to calculate the energy cost for that use.

These examples compare a fixed operating time. In an actual heating plan, that duration may differ by model and situation. Heat loss, the temperature setting and controls affect when the panel switches on. A higher output therefore does not necessarily mean the appliance heats for exactly the same hours as a lower-output model in your situation.

The colour version does not create a separate consumption formula. Compare models for the same heating purpose, comfort requirement and operating hours. An example for supplementary warmth at a workstation cannot be directly applied to primary heating of an entire home. We do not promise a fixed savings percentage applying to every application.

For a fair comparison, also include the heating you replace or continue using. To monitor actual energy consumption, use suitable measurement and record which appliances are included in the measured combination. The consumption and costs page explains the calculation method further. In your enquiry, we discuss how product selection relates to the room’s total use.
