Installation Recommendations for Interior Designers and Architects
1. Plan the heating system during the design stage
Plan the positioning of infrared panels together with lighting, furniture and other interior elements. This allows the heating system to be integrated into the space without compromising the visual design later.
2. Consider ceiling height and room geometry
Choose the panel positions according to the ceiling height, room shape and location of the heated zones to ensure even heat distribution.
3. Choose the most suitable installation option
Ceiling — a discreet solution that keeps wall space free.
Wall — allows the panel to be integrated into the interior both functionally and visually.
Portable solution — selected panel models can be used with floor stands, providing flexible heating without permanent installation.
4. Plan the heated zone and observe installation distances
The main heated zone should generally be planned approximately 3–4 m from the panel, depending on the panel model and output. The installation requirements for the specific panel model must also be followed, including the required distances from furniture, finishing materials and other interior elements.
5. Solutions for high ceilings
For rooms with high ceilings, the BC002 ceiling suspension kit can be used to suspend the panel at a suitable height. The kit includes 4 × 1 m suspension cables.
6. Integrate heating controls
Thermostats and smart controls allow individual control of the temperature and operating times for each room or heating zone. Up to 10 infrared panels can be connected to one Sundirect thermostat.
7. Determine heating output based on heat loss
The required heating output is determined according to the heat loss of the building and the individual room. The number, output and positioning of the panels are selected according to the calculated heating load.
8. Plan the electrical installation in advance
Plan the power supply points for the panels and the control components as part of the electrical design. This helps avoid visible wiring and maintains a clean, well-designed interior.
Examples — Infrared Heater Placement
1. Determining the Required Heating Capacity
The required heating capacity is calculated separately for each room, taking into account:
🟧 ✓ Room area and ceiling height
🟧 ✓ Building insulation and heat loss
🟧 ✓ Number of external walls in the room
🟧 ✓ Window and external wall area
🟧 ✓ Whether infrared heating is intended as the primary or supplementary heating system
The more external walls and windows a room has, the greater the heat loss will generally be and, consequently, the higher the required heating capacity.
Indicative heating capacity:
Well-insulated buildings — approximately 50–70 W/m²
Buildings with higher heat loss — approximately 100–150 W/m²
The exact required heating capacity should be determined based on the heat-loss calculation for the specific building.
Recommendation: It is advisable to design the heating system with a small capacity reserve. This allows the room to heat up faster and provides additional capacity during colder periods. It does not mean permanently higher electricity consumption — once the set temperature is reached, the thermostat automatically regulates the heating.
2. Selecting the Panel Type and Placement
The number and placement of panels should be selected according to the room’s function, geometry and main occupied areas.
🟧 ✓ Ceiling panels — keep walls free and allow heaters to be distributed evenly throughout the room.
🟧 ✓ Wall panels — suitable where ceiling installation is not possible or where the panel is intended to be integrated into the interior design.
🟧 ✓ Portable panels — a flexible solution for individual rooms or supplementary heating.
3. Correct Panel Placement
Infrared heating transfers heat primarily to surfaces and people within the radiant zone. Therefore, not only the total heating capacity but also the positioning of the panels is important.
🟧 ✓ Position the panels so that they effectively cover the main occupied areas.
🟧 ✓ In larger rooms, distribute several panels evenly so that their radiant zones complement each other.
🟧 ✓ In typical residential rooms, the ceiling installation height is generally approximately 2.2–3.0 m.
🟧 ✓ Do not position a wall-mounted panel directly opposite a window. Part of the radiant heat will be directed towards the glass — a surface with relatively high heat loss. It is more effective to position the panel near an external wall or window area and direct the radiant heat towards the interior of the room.
4. Practical Example of Heating Capacity and Panel Placement
Living room — 25 m²
Calculated heating requirement — 70 W/m²
25 × 70 W = 1750 W
A possible solution — 2 × 900 W ceiling panels, positioned to provide even coverage of the main occupied areas.
We use the same principle when preparing room layouts:
Room area → Required heating capacity → Number of panels → Panel placement
When to Conceal the Panel and When to Make It a Feature?
When to Conceal the Panel and When to Make It a Feature?
Infrared heating does not have to dictate the interior design — the panel can be almost invisible or become a deliberate design feature. The choice depends on the function of the space and the overall design concept.
🟧 ✓ Blend in — white ceiling panels visually blend into the ceiling, maintaining a clean, minimalist interior.
🟧 ✓ Integrate — LUX-Plus combines heating and LED lighting in a single ceiling element.
🟧 ✓ Make it a feature — black or ART panels can become an interior accent and part of the overall design concept.
🟧 ✓ Add functionality — in bathrooms, a heating panel can also function as a mirror or towel warmer.
🟧 ✓ Maintain flexibility — a portable panel allows the heat source to be repositioned without altering the interior.
🟧 ✓ Adapt to the architecture — different panel sizes, shapes and installation options allow the heating system to complement the room proportions, ceiling structure and overall interior composition.
The designer chooses not only where to position the panel, but also the role it plays in the interior — whether to blend it in, integrate it or make it a feature.

Portable Heating — Flexibility in Interior Planning
Sundirect portable infrared heaters allow you to create local comfort zones exactly where they are needed — without permanent installation or changes to the room’s architecture.
They are suitable for offices, workspaces near large glazed areas, residential spaces, lounge areas, showrooms and other environments where the heating solution needs to adapt to the interior and how the space is used.
🟧 ✓ Freedom in space planning — the heater can be moved and positioned wherever additional warmth is needed at any given time.
🟧 ✓ Efficient placement near glazed façades — TOWER radiates heat in three directions. By positioning the non-heating side towards the glass, the heat is directed towards the room and its occupants rather than towards the glazed façade.
🟧 ✓ No permanent installation — no wall or ceiling mounting is required, allowing the interior and architectural design to remain unchanged.
🟧 ✓ Minimalist design — clean lines and a neutral appearance allow the heater to integrate naturally into modern office, residential or commercial interiors.
🟧 ✓ Targeted zone heating — specific work, lounge or occupied areas can be heated without raising the temperature throughout the entire room, reducing unnecessary energy consumption in other zones.
🟧 ✓ Smart control — temperature adjustment and WiFi control allow the heating to be adapted to the use of the specific zone and the daily schedule.

ART infrared heaters - heating as an interior element
The ART Series combines infrared heating with individual interior design. An infrared panel can become a work of art, a photograph or a visually integrated interior element while retaining its full heating functionality.
Each ART panel is individually produced. The client selects an image and provides it as a digital file, while we prepare it for printing according to the selected panel size. The image is printed on a special heat-resistant UV film and applied to the surface of the infrared panel.
🟧 ✓ Individual design — use a photograph, artwork, graphic or other visual material selected by the client
🟧 ✓ Image quality — the required image resolution in pixels is determined according to the selected panel size; for example, for a 60 × 120 cm panel, a file of approximately 4700 × 9450 px or larger is recommended for high-quality printing
🟧 ✓ UV printing — the image is printed on a special heat-resistant UV film and professionally applied to the infrared panel
🟧 ✓ For commercial projects — professional photography, corporate visual identity, graphics and custom designs created for a specific interior can be used
🟧 ✓ Individually produced in Latvia — ART panels are individually prepared and printed in cooperation with a professional printing company in Latvia
From Heating Panel to Interior Design Element
The ART solution allows infrared heating to become an intentional part of the architecture and interior design rather than something that needs to be hidden. It is particularly suitable for residential interiors, hotels, restaurants, offices, public buildings and individually designed commercial spaces.
