Welltherm designer infrared heating for your interior
28 April 2026 · Welltherm Netherlands / HeatXL
Welltherm designer infrared heating starts with the room where you want to live and work. Perhaps you want a discreet plate matching the wall colour, a glass surface or a mirror that also provides warmth. Design offers many possibilities as long as output and positioning suit use. We connect your desired appearance with a technically suitable heating solution, supported by HeatXL for the Benelux.
Key points
- Choose finish and heating function together: an attractive panel needs a suitable position and sufficient capacity.
- Metal, glass, mirror and RAL colour have different product details and possibilities.
- A photograph or print must be ordered as an original product version; covering an existing panel is not equivalent.
- An on-screen colour or proof is an approximation; material and production may cause colour differences.
- Mounting, temperature controls and any lighting form part of the design.
Design according to the room’s function
A heating panel is a visible part of the interior but also has a specific task. It must provide warmth where needed. Start by describing the room: where do people sit, when do they use it and what background heating exists? This information helps determine whether you want targeted supplementary warmth or a complete heating solution for the room.
The panel converts electrical energy into heat and warms its surface. From there, it emits radiant warmth towards surrounding people and surfaces. Heated surfaces then release warmth to the surroundings, affecting air too. The external finish does not change the need for sufficient capacity to compensate for room heat loss.
A discreet background or visible accent
A white version may complement a light wall or ceiling. Alternatively, choose a colour with a deliberate presence in the interior. The difference involves not just shade but dimensions, orientation and position among other elements. A narrow panel beside a door appears differently from a wide plate above a low cupboard. Consider the whole from places you frequently occupy.

A deliberately visible panel need not dominate. Following lines in furniture, doors and wall areas can make the plate fit logically in the interior. An initial sketch is often enough. Mark external dimensions on the wall using paper or tape and assess the result by day and evening. The product dimensions then gain a real scale in your room.
Design follows practical positioning
Do not position the panel solely where it looks attractive in a photograph. If large furniture restricts heat transfer to the occupied zone, another position may be necessary. Curtains, a swinging door and future furniture also affect clearance. Prescribed distances come from the chosen article’s manual. Interior preferences cannot replace them.

For primary heating, we assess room heating demand. Dimensions give an initial impression, but insulation, windows, ventilation and outdoor temperature matter. A panel in a particular colour does not automatically have enough output for a room of a certain floor area. Sometimes design improves with two well-positioned panels rather than one version expected to solve too much visually and technically.
Choose materials and finishes
Our collection offers several ways to incorporate warmth into an interior. Compare series for appearance, external dimensions, weight, output and permitted mounting. Similar dimensions do not mean two versions are technically interchangeable. A glass plate may need different mounting components from a metal panel. An accessory fitting one version does not automatically fit another either.
Metal as a flat part of the design
Welltherm metal panels offer various dimensions and finishes. In the white series, for example, the catalogue specifies PB0710 with 710 watts, 59.2 × 119.2 × 1.7 cm and 14.0 kg. This gives a concrete sense of scale and weight. External dimensions are deliberately precise: a broad description such as 60 × 120 cm is useful for comparison but insufficient for mounting preparation.

Alongside white, options include Sand, Graphit and RAL versions. Sand and Graphit are predefined product variants; for RAL, discuss the desired colour for the relevant series. Choose finishes with other room materials in mind. A silk matt or textured appearance may look different under another light from a smooth, glossy material. Have specific version details confirmed.
RAL colours and colour expectations
A Welltherm panel in a RAL colour can complement a wall, cupboard or detail you want to repeat. Record the desired RAL number in the enquiry. A photograph of a coloured wall is not by itself an unambiguous colour specification. Camera, screen and ambient light affect what you see. An agreed colour number provides a more useful product-selection basis.

Material and surface remain important even then. The catalogue identifies colour on a correction proof as an approximation and notes possible slight production differences due to material. Even with the same RAL number, panel and wall paint may look slightly different because of material and finish. Assess a suitable colour reference where possible and discuss how important a very close match is for your design.
Glass and reflective surfaces
Glass gives a room its own appearance. Satino has a satin white surface, described in the catalogue as comparable to RAL 9016. A mirror version combines a reflective surface with heating. For both, consider desired orientation and how the panel is viewed in the room. Reflections may contribute to appearance and deserve attention when choosing position.
For mirror heating, position is often initially selected according to daily use: where do you want to see yourself and at what height? Then connect that question with available mounting position and heating demand. A mirror above a washbasin must also suit the humid environment and exact electrical positioning. Find more information under Welltherm mirror heating. The heated surface may limit condensation under certain conditions, but we do not promise it always remains entirely condensation-free.
Coordinate colour, images and lighting
A personal version makes the panel part of the room’s story. This may be a colour repeated throughout the interior or an image fitting a chosen wall area. Also consider how long your interior choice will last: furniture and wall colours may change later. A discreet version may remain broadly useful, while a distinctive design is a deliberate personal choice.
An original photo or image version
An image panel is manufactured as a purpose-designed original version. Specify the subject you want and have the file’s technical quality assessed. For metal image versions, the catalogue names JPEG, TIFF and PSD file formats and recommends preferably 300 dpi and a minimum of 100 dpi at final panel size. The specific file still needs assessment, especially for substantial enlargement.

Choose cropping suited to panel dimensions. A narrow rectangle may need another aspect ratio from a square panel. Important details must not accidentally end up too close to the edge. A proof helps discuss cropping and expected appearance. Final colour may differ from a screen due to material and production. Also use only an image for which you have the required usage rights.
Covering, painting or applying stickers to an existing heating panel yourself is not an equivalent way to create an image panel. Heat emission and product use must remain consistent with the manual. Ask about original possibilities in the relevant series before choosing a personal finish. Your chosen appearance then remains connected to a version developed for that application.
The effect of lighting
Consider a possible panel colour with daylight and normal evening lighting. Warm light can create a different impression from light near a window. A ceiling lamp’s position also affects how a surface is seen. Reflections of light fittings are especially relevant for glass and mirrors. A design looking calm from one position may reflect a distracting light from the sofa.
Welltherm LED frames are available for compatible panel combinations. The catalogue describes warm white 3000 K light and dimmable possibilities. The frame is a separate accessory with its own dimensions, output and protection rating. Select required lighting according to the room’s lighting needs, while selecting the panel for heating demand. Sharing one product position does not make those calculations identical.
Use light and warmth separately
In the evening, you may want light without additional warmth; during the day, warmth may be needed while daylight is sufficient. Include that preference when selecting power supply and controls. Available fixed and wireless solutions need compatible components. We do not infer an app function or complete smart controls solely because a lighting frame is dimmable.
For a bathroom, assess the complete combination too. Panel and LED frame may have different protection ratings. A panel suitable for a particular position does not make every added lighting accessory suitable there. Consult product information under LED frames for infrared panels and have the combination checked against electrical positioning.
Include mounting and controls in the interior plan
The most attractive version looks better when mounting is planned beforehand. Where does the connecting cable run? Which wall supports the panel? Where are temperature controls positioned? Answering these alongside finish selection avoids resolving visible details only after choosing the product. A technical drawing need not be complicated to show important points.
The wall as a supporting surface
For wall mounting, check the supporting surface and required fixings. A firm load-bearing wall differs from a thin lining wall. Product weight, mounting points and structure determine the necessary approach. Have suitable fixing materials selected and check for pipes or cables. A tidy finish around the panel starts with reliable mounting.

Available space includes more than the plate’s front. Include prescribed distance and room around the mount. Do not position furniture, curtains or loose materials in clearance required by the manual. A narrow recess may look attractive but is usable only if specific product requirements permit it. We do not give universal distances applying to every series.
The ceiling as a discreet position
When a wall has another clear function, a suitable ceiling panel may provide an alternative. You retain space for a bookcase or large window, for example. Assess height, available mounting position and heat distribution. The ceiling must support weight using prescribed fixings. Plasterboard and loose ceiling tiles are not suitable supports based on appearance alone.
For ceiling mounting of WS, SP and TA glass ranges, prescribed glass retaining clips are mandatory: set 14170 for round glass heaters and set 14171 for rectangular glass heaters. Follow the chosen model’s mounting manual.
Recessed mounting needs an approved combination of panel, frame, supporting structure and retention. Select exact components and cut-out dimensions using the manual. Do not simply place a panel in a grid because nominal dimensions approximately match. A metal panel designated 60 × 60, for example, may actually measure 59.2 × 59.2 cm. Technical mounting must therefore be more concrete than the shape on a sketch.
A freestanding arrangement as part of the design
A floor stand may suit desired freestanding positioning. The stand then forms a visible part of the combination and occupies floor space. Different solutions exist with and without wheels, requiring panel compatibility checks. Consider circulation routes, cable and floor alongside panel colour and orientation.
A movable version may be convenient when rearranging a room, but the new location must be suitable again. Positioning behind large furniture may limit usable warmth. If a panel should remain in one position for longer, fixed mounting may better suit use. Compare options under our mobile panel stands.
Give temperature controls a logical position
A precon connection is a connector for a suitable panel connection, not a complete thermostat. Select the required receiver and controller with the panel and decide where controls are comfortably accessible. A temperature sensor must measure representatively according to its own instructions. A position directly beside another heat source may be unsuitable.
The operating programme can match the room’s function. A study may have different hours from a living room or bathroom. Remote operation needs compatible components, and not every combination offers the same functions. Explore precon connections and controls and our thermostats before finally finishing electrical provisions.
Choose your designer heating concretely
With Welltherm designer infrared heating, we combine interior preferences and heating requirements. Start with a few clear preferences: material, desired colour, mounting position and room function. You need not know an exact article yet. The correct version follows after assessing room and technical possibilities. This keeps selection clear and lets you compare the final proposal purposefully.
Make a small material plan
Collect colours and materials near the panel. Consider wall paint, wood, metal details, floor and curtains. Record which elements stay and which may change later. A colour preference becomes more concrete than a general description such as warm white or light grey. For RAL, provide the colour number; for images, discuss file, dimensions and cropping.

Add photographs showing the wall or ceiling within the whole room. A close-up of the desired position is useful but often does not show seating or door swing. Overview images help assess appearance and heating function together. A dimensioned sketch makes panel-to-furniture proportions concrete.
A choice for now and later
At final selection, consider changes already expected. Will a larger cupboard arrive, the room gain another function or the ceiling be lowered later? These plans may affect available position and connections. A considered panel choice need not anticipate every future interior, but known changes can be included before mounting.

When several people use the room, discuss desired appearance and controls together. The person choosing the interior and daily user are sometimes different. A clear programme and accessible controller help make the design pleasant in practice. Record agreements with the proposal so material, mounting and use retain the same assumptions.
Consider capacity and costs transparently
Operating costs relate to electrical output, actual operating hours and your electricity tariff. A RAL version or mirror is not more economical than another suitable heater solely because of its appearance. Examine the full application. Is the panel added alongside existing heating, or does existing use genuinely change? Without that distinction, cost comparison is difficult to assess.

For purchase pricing, request a proposal for the selected combination. Include mounting accessories, connections, controls and any lighting. A plate-only price does not show what the complete solution requires. You receive a quotation for the complete combination with chosen version, accessories and controls. Clear specifications help assess what you receive for the room.
Read a proposal before choosing
Check that the proposal describes the same colour, orientation and external dimensions used in your plan. Also assess output, weight and mounting solution. A personal version needs clear agreed colour or image details. Uncertainty about supporting surfaces, connections or controls must be resolved before preparing the installation accordingly.
HeatXL supports Welltherm in the Benelux with product selection and practical coordination. Through a quotation enquiry, share your design and room data. Also explore our infrared panels and metal RAL versions for an initial comparison of possibilities.
Handle a heated surface correctly
The panel remains a heat source even when it looks like a mirror or image. Its surface becomes warm and may be hot. Maintain clearance and do not cover it with textiles or decorations. Follow the model manual for cleaning and use. Decorative appearance must not lead to treating it as an ordinary unheated wall plate.
Applicable panels carry a five-year warranty under our conditions. Accessories may have different conditions. Keep confirmed article data and product documentation, and consult the warranty conditions when examining cover. A suitable design then accounts for both the first impression and daily heating use.
From selection to a suitable proposal
A design choice becomes stronger when appearance, heating demand and mounting support each other. Establish desired material and colour, have capacity assessed and document connections and controls immediately.

Frequently asked questions
Which forms of Welltherm designer heating are available?
Various metal and glass versions are available, including white, Sand, Graphit, RAL colour, mirror and original image versions. Exact dimensions, outputs and mounting requirements differ per series. Select a specific version according to room and desired appearance.
Can I order a panel exactly matching my wall colour?
For suitable RAL versions, specify your desired colour number. We do not promise a completely invisible match with every wall paint. Screens and proofs are approximations; material and production may create slight colour differences.
May I paint or apply stickers to an existing panel myself?
Use the product according to its manual. Your own coating, sticker or covering is not an alternative to an original photo or RAL version. Discuss personal finishes beforehand so appearance belongs to a purpose-designed product version.
Does a mirror panel use less electricity than a white panel?
Finish alone gives no fixed consumption outcome. Output, operating hours, heat loss and controls together determine use. Compare technical details and room application rather than assigning savings to appearance.
Can designer heating provide primary heating?
This requires sufficient capacity for the room’s heat loss and suitable distribution and controls. An attractive position or colour is insufficient to establish this. Have the room assessed when replacing existing heating.
Can I combine a heating panel with LEDs?
LED frames are available for suitable panel combinations. Check dimensions, supply, controls and protection rating for the whole arrangement. Light and warmth have different functions and must match their respective requirements.
Is a thermostat included in the panel?
Check the proposal’s component arrangement. The precon connector is not complete temperature control. Panel, any receiver and compatible controller are selected together for intended use and available electrical connection.
How do I request advice for my interior?
Send room dimensions and photographs, intended mounting position and material or colour preferences through the quotation enquiry. State whether you want supplementary warmth or complete room heating. We discuss suitable versions and provide pricing for the selected combination.
