Welltherm infrared mirrors: warmth and mirror together
28 July 2026 · Welltherm Netherlands / HeatXL

Welltherm infrared mirrors combine a practical reflective surface with electric radiant warmth. This may be a logical bathroom choice, but also suits consideration in a hallway or dressing room. First select a suitable mirror position and size, then connect that choice with output, mounting and controls. We help assess both functions together so the mirror panel matches daily use.
Key points
- An infrared mirror is a heating panel with a reflective front, not an ordinary mirror with only a small demisting function.
- Capacity is selected for supplementary warmth or the heat loss of the entire room.
- A warm mirror surface may reduce condensation; ventilation, moisture and warm-up time remain influential.
- Our mirror series has exact model dimensions, weights and mounting requirements checked beforehand.
- Select connections, temperature controls and any lighting as a suitable complete combination.
Two functions in one mirror panel
A Welltherm infrared mirror has a reflective surface and heating function. Behind the front, electrical energy is converted into heat. Its heated surface emits radiant warmth towards surrounding people and surfaces. Heated surfaces subsequently transfer warmth into the room, affecting air too. The panel is therefore a heat source you can simultaneously use as a mirror.
This differs from an ordinary mirror with limited heating film intended only to warm part of its surface. When comparing products, examine actual heating output and the described application. A heated mirror is a broad product description. Specific data clarify whether you are choosing a room-heating panel and its capacity.
Connect mirror position with heating position
A mirror’s practical height and width follow from how you use it. Above a washbasin, consider users and basin arrangement. A dressing room may need a taller or longer reflective surface. That initial choice is then checked against heating function: does the panel reach the occupied zone, and does it have sufficient capacity for its intended role?

A mirror visually fitting exactly between two cupboards is not automatically suitable there as heating. Clearance and mounting must meet model requirements. Objects in front may also restrict heat transfer towards the desired position. A tall cupboard beside the washbasin or newly installed furniture therefore belongs in the assessment.
Supplementary warmth or primary heating
For extra comfort alongside existing heating, a mirror panel may have a supplementary role. Specify which heating provides background temperature and when the mirror is used. If heating the entire room with the mirror, we assess heat loss and required capacity. Windows, insulation, ventilation and desired temperature matter.

Visible mirror area alone does not establish whether the panel can heat an entire bathroom. A broad mirror may lack capacity in a cold bathroom; elsewhere, a smaller suitable model may match demand. Base selection on both functions. The mirror must be pleasant to use and fit the heating objective.
The room warms too
When the mirror supplies sufficient warmth, it affects room temperature as well as direct thermal sensation. Speed depends on starting conditions and heat loss. A bathroom already heated daily responds differently from a cold room after prolonged absence. The panel must warm first, and the room also needs time to reach the selected temperature.

Choose a Welltherm infrared bathroom mirror
A Welltherm infrared bathroom mirror brings together mirror use, warmth, moisture and electrical positioning. Start with a sketch showing washbasin, shower, bath, door and ventilation. Identify the desired mirror position and existing electrical connection. These details allow assessment of the specific location and adaptation of the version accordingly.
A bathroom may require different temperatures and operating hours from a hallway or study. Perhaps you mainly use it early in the morning and later in the evening. A suitable timed programme can support those hours if controls and capacity match. Also discuss existing underfloor or other background heating. The mirror then receives a clear role within the whole arrangement.
What a warm mirror surface can do about condensation
Condensation forms when moist air meets a sufficiently cold surface. A heated mirror may limit formation because its surface is warmer. However, the effect relates to mirror temperature, moisture quantity and bathroom conditions. Particularly shortly after switching on, the surface may not yet be warm enough everywhere.

Include warm-up behaviour in the programme when a clear reflection matters. This is a practical reason to discuss controls and timing alongside desired room temperature. Good ventilation nevertheless remains necessary to remove moisture. A heated mirror does not change how much moisture a shower introduces or replace its removal.
Mirror heating and ventilation remain different functions
A panel adds warmth; ventilation provides air exchange. Use both appropriately for the bathroom. If the room stays humid long after showering, assess ventilation and room use separately. Moisture problems in the building structure likewise need their own assessment. Heating selection forms part of the comfort plan, not a general solution for every moisture source.
Do not merely run the mirror longer to compensate for an unclear ventilation problem. First discuss air exchange and whether operating times align well. A realistic plan considers daily showering, existing provisions and desired temperature. Explore infrared bathroom heating to include those questions in your enquiry.
Protection rating of the chosen article
Our catalogue specifies IPX4 for the mirror series. This detail belongs in product selection and must be assessed with positioning and connections. The standard WS/SP/TA glass-range manual excludes mounting the panel and connection in bathroom zones 1 and 2. Have electrical and practical requirements for the exact mounting position checked by a competent professional.

Connections, controller and any lighting may also have their own conditions. A lighting frame fitting a mirror is not thereby suitable for every bathroom position. The complete arrangement is assessed for the location. Specify not only panel type but also desired accessories and how you want to use the controls.

Dimensions and outputs of our mirror series
The Welltherm mirror series has a 5 mm ESG-H safety-glass front and ESHC Plus heating technology. The catalogue includes various sizes, each with its own output and weight. Compare these details together. Width and height determine mirror use and interior position; output and weight matter for heating capacity and mounting.
Use the complete article code when selecting a model. A description such as a 60 cm-wide mirror does not establish dimensions or output sufficiently. Orientation and desired fixings are checked beforehand too. This keeps the requested version and accompanying components clear.
Compare square and rectangular versions
SP0370 is the square version measuring 60.0 × 60.0 × 2.2 cm with 370 watts and a weight of 9.6 kg. SP0580 measures 60.0 × 90.0 × 2.2 cm, has 580 watts and weighs 13.5 kg. These models show how dimensions and capacity change together. Establish desired orientation and mounting according to model documentation.
For a larger reflective surface, the catalogue specifies SP0780 with 60.0 × 120.0 × 2.2 cm, 780 watts and 17.3 kg. SP0930 has 60.0 × 150.0 × 2.2 cm, 930 watts and 22.0 kg. Alongside wall space, the larger version requires more attention to handling and support. A suitable wall and fixings are part of the selection.
The larger SP1250 version
SP1250 has external dimensions of 75.0 × 150.0 × 2.2 cm, an output of 1250 watts and a weight of 27.5 kg. It may be an option when greater dimensions and capacity are needed. It is not automatically correct because it has the highest listed capacity. Heating demand, mirror position and mounting requirements must suit that version.
A larger panel may be useful in a particular room, while elsewhere a smaller mirror plus another heat source may be more logical. Selection is therefore not solely by size or output. Explore our mirror heating for the product option and have room data compared with model data.
Determine appropriate heating capacity
For complete room heating, we assess heat lost through construction and ventilation. An external wall with extensive glazing needs a different assessment from a well-insulated internal room. Desired temperature and usage routine matter too. Floor area is useful information, but no single output rule describes every bathroom or dressing room well.
For supplementary warmth, we also assess existing background heating and where you want extra warmth. If the mirror mainly faces away from the occupied zone, another position or additional version may be needed. An overview of room and furniture helps explain this. Product selection then remains connected to useful warmth.
Hallways and dressing rooms as other applications
A mirror panel need not be chosen only for a bathroom. In a hallway or dressing room, its reflective surface may also have a clear function. These spaces require their own assessment. A hallway with a frequently opened external door may respond differently from an enclosed dressing room. Provide operating conditions and select controls for hours actually used.
Prepare mounting, connections and lighting
The wall and fixings must support the selected mirror panel according to requirements. Catalogue weight shows why visible wall finishing alone does not provide complete information. A lightweight lining wall and solid wall may need different fixings. Have supporting provision established before preparing installation.
Also examine clearance around the panel and cable routing. Exact distances come from the chosen version’s manual. A mirror in a narrow recess is usable only when model conditions permit that position. The installation combines a pleasant reflection with a correctly mounted heat source. Both functions deserve design attention.
Handle glass carefully
A large mirror panel can be awkward to position due to dimensions and weight. Ensure the support and people needed for mounting are available. Do not use the connecting cable as a handle or temporary support. Follow product-documentation procedure and fixings. Check final position and retention before using the installation.
For desired ceiling mounting, assess the model and prescribed components separately. Permission for wall mounting does not provide complete ceiling-fixing instructions. Support and retention must suit the specific application. Ceiling mounting of rectangular SP mirror panels requires glass fixing set 14171 in addition to prescribed panel fixings. Follow the glass installation manual.
Precon and suitable temperature controls
The precon connector offers a connection option for a suitable electrical arrangement. It is not a complete thermostat. For room heating, select a compatible controller and any receiver together with the mirror panel. State whether you want a timed programme, simple local controls or other functions. Selected components determine which operation is actually possible.
Position the temperature sensor according to its own instructions in a representative location. It need not be directly beside the mirror panel and must not be adversely influenced by another heat source. Electrical connections are assessed for the relevant location and load. Find more information under precon connections and controls and our thermostats.
Add a compatible LED frame
LED frames are available for compatible panel combinations. This can add light around a mirror surface and visually unite both functions. The frame has its own dimensions and electrical output, with supply and controls selected alongside it. Heating capacity and desired lighting are separate selection questions. An attractive frame does not make insufficient heating output adequate.
The catalogue lists warm white 3000 K light and dimmable possibilities for LED frames. Check exact compatibility with the selected mirror article. A lighting frame’s external dimensions may differ from the mirror’s. Its protection rating is also a separate detail. Explore LED frames for infrared panels and have the complete arrangement assessed for your mounting location.
Use and cleaning
The mirror surface becomes warm and may be hot. Preserve prescribed clearance and prevent unwanted contact. Do not hang towels, clothing or decorations over the panel. A reflective front does not change that it is a heating appliance. Follow the version’s cleaning requirements and let the panel cool according to its manual first.

Request a mirror solution for your room
A suitable proposal starts with describing the room and mirror position. Send dimensions, ceiling height and photographs showing both the chosen wall and the rest of the room. Specify existing heating and available insulation information. For a bathroom, shower, bath and ventilation positions also help explain the situation.
HeatXL supports Welltherm in the Benelux with product expertise and application coordination. Through a quotation enquiry, have mirror panel, connections, mounting and controls assessed together. Pricing is provided on request for the selected combination. This clarifies which version and accessories are included in the proposal.
Describe daily use
Record when you use the mirror and room. A brief morning visit has a different routine from a room occupied longer. State whether you mainly want extra warmth or complete room heating too. If reducing condensation matters, include that as a usage preference. Controls and warm-up period can then be discussed according to this daily routine.

In a family, several users may use the bathroom consecutively. Ventilation remains important, and heating demand may change during the morning. Describe those conditions without immediately choosing a model. The panel proposal follows from room data and desired functions so mirror dimensions are not considered separately from heating requirements.
Test mirror positioning within your daily routine
Before final selection, mark desired external dimensions on the wall with paper. Assess scale from the door and where you normally stand before the mirror. Include washbasin height and any wall cupboards. You can then see whether mirror space suits users and whether another proportion feels more pleasant. This assessment accompanies technical mounting checks.
Also consider reflections. A window or light fitting may attract considerable attention from a particular angle. Light-source positioning may matter for comfortable mirror use, while panel positioning remains important for heat. Considering both before finishing connection points allows a more focused design. Selected mirror dimensions and lighting preferences together are not yet a final electrical plan.

If sharing the room, discuss controls with other users. Who selects the programme and which settings should be easy to adjust? Simple, clear controls may be more practical than rarely used functions. Identify desired options in the enquiry and have compatible components selected. The programme can then be adapted to actual operating times.
After installation, follow how room and mirror surface respond initially. Record when heating is used, whether room temperature matches preferences and what happens after showering. These concrete observations help with programme advice. They provide more information than merely concluding the panel should run longer or shorter.
Examine electricity consumption
Use output and actual operating hours for consumption. A 780-watt mirror panel uses 0.78 kWh during one full-power hour. Temperature controls may switch off intermittently during a longer period of use. Bathroom availability therefore does not automatically equal full-power operating time.

Costs then depend on your electricity tariff. Include existing heating in the comparison if it remains. A mirror panel does not provide a fixed savings percentage for every bathroom. Insulation, temperature, operating duration and coordination with other heating affect the outcome. Actual measurements help refine an initial estimate later.
Keep article details and warranty information
Check the proposal for mirror code, dimensions, output and weight. Also examine confirmed orientation, mounting accessories and control solution. Applicable panels carry a five-year warranty under the conditions; accessories may have different cover. Consult our warranty conditions and keep model data and manuals.

A suitable arrangement gives the mirror a clear place in your room. You have a usable reflective surface, suitable heat source and controls matching use. Preparation makes it easier to bring both functions together in one carefully selected Welltherm solution.
From selection to a suitable proposal
Choose your mirror panel according to both desired mirror dimensions and heating demand. Then have mounting position, connections and controls assessed as a whole. Request a proposal for Welltherm infrared mirrors with your bathroom, hallway or dressing-room details. We help select suitable versions and components.
Frequently asked questions
Does a heated mirror never mist again?
A warm mirror surface may reduce condensation, but results depend on moisture, temperature, ventilation and warm-up time. The panel must warm first and ventilation remains necessary. Assess the operating programme with those conditions in mind.
Can a mirror panel heat my entire bathroom?
This requires sufficient output for bathroom heat loss and suitable positioning. Insulation, windows, ventilation and desired temperature matter. If the mirror supplies supplementary warmth, existing background heating is also included.
Which outputs does the Welltherm mirror series have?
The catalogue lists SP0370, SP0580, SP0780, SP0930 and SP1250 with 370, 580, 780, 930 and 1250 watts respectively. Dimensions and weight differ by article. Select the model for both functions: mirror use and heating capacity.
Is IPX4 enough for every bathroom position?
Protection rating is product data, not general permission for every location. Have position relative to water, connections and any accessories assessed as a whole. Model requirements and specific electrical positioning remain decisive.
Does the front become hot?
The mirror surface becomes warm and may be hot. Prevent unwanted contact, do not cover it and preserve clearance according to the manual. Reflective appearance does not change that it is a heating panel.
Do I need a thermostat alongside the connection?
Suitable temperature controls are selected for room heating. The precon connector is not a complete thermostat. Panel, any receiver and controller are coordinated for desired operation and application.
Can I add lighting around the mirror?
Welltherm LED frames are available for compatible combinations. Check panel compatibility, external dimensions, supply, controls and protection rating for the complete arrangement. The specific mounting position is assessed separately, particularly in a bathroom.
How do I request pricing for a mirror solution?
Send room dimensions and photographs through the quotation enquiry and describe mirror position, existing heating and desired controls. State whether you want extra warmth or primary heating. We propose a suitable combination and provide pricing.
