Welltherm infrared towel radiator: a complete selection guide

16 June 2026 · Welltherm Netherlands / HeatXL

Welltherm bathroom panel with two towel rails and towels against a green wall

Giving a towel a convenient place and organising bathroom warmth are two requirements you can consider together. A Welltherm infrared towel radiator is a specific product choice for this purpose. It is not an ordinary infrared panel over which you subsequently hang textiles. The intended range, heating system and corresponding rails determine how the towel function is used responsibly.

Key points

  • Use only the intended towel version with suitable rails belonging to that range.
  • BKW Plus combines towel drying in the lower section with room heating above.
  • Select dimensions, output and the number of rails according to your bathroom and towel usage.
  • The models described are intended for wall mounting; have the electrical arrangement and water environment assessed.
  • Coordinate controls, ventilation and periods of use together, and calculate consumption using actual operating time.

In this guide, we take you from your daily routine to the version that suits it. Discover how our bathroom versions combine room heating and towel drying, which product dimensions and accessories are available, and what mounting and controls require. Welltherm NL and HeatXL then help coordinate the combination with your bathroom.

What makes a Welltherm towel model special?

Two functions within one version

An electric infrared panel emits radiant warmth through its heated surface. This energy reaches people and surfaces in the room. The heated surfaces subsequently transfer heat to their surroundings, allowing the air to warm up too. With suitable capacity, a bathroom version can therefore contribute to heating the room alongside its own towel function.

Our 2026 catalogue describes the BKW Plus bathroom collection with a dual heating system. The lower section is designed for towel drying; the upper section provides room heating. The catalogue describes central control of both heating zones through one room thermostat. These are functions within a specifically designed product, rather than a general feature of every Welltherm panel.

A towel model still needs time to warm up. A damp towel also needs time to dry. How long this takes depends on factors including the fabric, moisture and use. We therefore select the product and programme according to your routine, without assuming a fixed drying time for every towel. A practical plan takes account of both the bathroom and the towels present.

The role of the special rails

The intended towel rails hold the fabric in its designed position relative to the appliance. They are selected for the relevant range and version. Width, fixing method and the possible number of rails are product details to consider when choosing. An arbitrary rail that happens to fit on the same wall is not automatically a suitable panel accessory.

Do not place towels directly over an ordinary panel. The BP bathroom panel is mounted with its connection cable at the bottom; the upper 75 centimetres across the full width are exclusively for room heating and remain completely free of textiles. Use only the intended rails in the lower section for towel drying. A towel model must likewise be used in accordance with its specific instructions. The selected accessory provides an intended place for fabric; it does not permit every method of hanging. Therefore, document the rail combination when selecting the product and follow the instructions for use and positioning.

The number of people in your household may influence your choice. One towel for a short routine presents a different requirement from several large bath sheets after successive showers. Indicate which fabric you want to hang and where it is subsequently used. Dimensions can then be assessed according to the practical task rather than the radiator’s appearance alone.

Towel care and ventilation remain necessary

Drying and heating do not turn towel management into a complete hygiene solution. Wash textiles according to their care instructions and replace them when necessary. Spread towels in the prescribed manner so that a tightly packed pile does not restrict the intended operation. A heating product does not replace proper care of the textiles used.

Read more

Moisture evaporating from a towel initially remains in the bathroom air. Ventilation must help remove this moisture load. The heating plan and air exchange therefore need to work alongside each other. Do not close vents to retain more warmth in the room. Ventilation remains relevant after a shower and during drying.

If damp patches or mould recur, investigate the cause. This may be inadequate ventilation, a leak or a building defect. A towel radiator provides no general guarantee against such problems. Understanding what is happening first and then coordinating the complete bathroom plan provides a better starting point than expecting a heating product alone to solve a moisture problem.

Selecting finish, dimensions and rails together

Comparing Satino glass and metal

The catalogue includes different bathroom finishes. Satino has a satin-finished glass front; metal finishes described include white, graphite black and sand. You can therefore coordinate the appearance with tiles, sanitary fittings and accessories. Select the finish within the suitable version once the heating function and available mounting position are clear.

Read more

The models have their own weights and depths. A glass panel and a metal version of the same height do not automatically weigh the same. This matters for wall fixing. Always consider the complete product, including output, dimensions and weight. A restrained appearance tells you little about the substrate that must safely support the appliance.

You can coordinate a white version with light sanitary fittings or make a dark version a prominent part of the interior. Consider colour and texture together with the other materials. Screen images help with initial orientation, but the final finish is confirmed for the specific product. Discuss important colour preferences before placing the order.

Three heights offering different practical space

For the BP bathroom versions described, our catalogue lists dimensions including 60 by 120, 60 by 150 and 60 by 180 centimetres. Their outputs are 550, 660 and 850 watts respectively. One, two and three possible rails are listed for these versions. Dimensions therefore determine not only appearance but also the practical possibilities within the range.

Read more

These dimensions and outputs are not automatic recommendations for three fixed bathroom sizes. Whether a model can heat the room independently depends on heat loss and the desired temperature. A tall version providing sufficient space for textiles must also suit the room technically. Conversely, an output may be appropriate while the height proves inconvenient in the bathroom.

Measure the entire available wall and consider the positions of doors, furniture and water points. Account for prescribed clearances and for actually hanging and removing towels. A model fitting into a narrow recess may be awkward in practice if its rail is difficult to reach. The daily action therefore forms part of dimension selection.

Specifying BEE rails and the version

The catalogue lists brushed stainless steel towel rails BEE0430 and BEE0550 with a design open at one end. Their stated lengths are 43 and 55 centimetres. BEE0650 is also described as a continuous 65-centimetre rail. These components are selected within the compatibility and mounting requirements of the relevant bathroom version.

A white metal set version, BKMW0660, is also described. The catalogue specifies 660 watts, dimensions of 60 by 150 centimetres and a white towel holder included in the set. Even with a set, it is sensible to record precisely which components are supplied. You then compare complete combinations and know which accessories belong with the selected version.

Read more

Also discuss which side is practical for an open rail. A cupboard, shower screen or door may determine the side from which you can easily hang a towel. The catalogue describes left- or right-hand fixing possibilities within the range. Have the desired combination confirmed for your model so that accessibility and the installation plan align.

Considering capacity and mounting in relation to the room

Primary heating requires a heat assessment

If you wish to replace an existing radiator, it must be clear whether the towel version can take over the entire heating function. Measure the bathroom and record its height. Provide details of external walls, glazing, insulation and ventilation. The desired temperature and starting temperature on cold mornings also count. This allows us to assess the model in relation to the whole room.

Read more

A general wattage for a six-square-metre bathroom is not a personalised calculation. The same area can have different heat losses. An internal bathroom has different conditions from a room beneath a roof with extensive external surfaces. Periods of use and any existing underfloor heating also influence the requirements. Therefore, describe the actual situation and the intended role of the appliance.

A towel model can be assessed as a supplementary heat source when another system maintains the baseline temperature. The proposal then need not fulfil the same role as a complete replacement. Indicate which heat source remains and how it is currently controlled. This creates a suitable combination of room comfort and towel functionality, with clear expectations for both.

Wall mounting in an accessible position

According to the catalogue, the bathroom versions described are intended for wall mounting. This suits hanging and removing towels. A towel model does not simply become a ceiling panel by positioning it differently. Follow the exact version’s mounting method and select the wall position according to accessibility, heat output and the bathroom layout.

Read more

The rails should be convenient to use without having to move close to a hot surface or reach over furniture. Also consider users’ heights. In a household with children, actions and movement routes may differ from those of adults. Indicate the desired usage height, but have the final position assessed within the product requirements.

An open door, tall cupboard or large shower screen can influence the selected location. Consider both the practical towel-handling task and heat emission into the rest of the bathroom. An accessible model entirely hidden behind another feature is not automatically well positioned for room heating. Both functions are therefore considered together when choosing the mounting location.

Maintaining load-bearing capacity and clearances

A tall bathroom version can weigh a considerable amount. For example, the catalogue gives 20.3 kilograms for the 60-by-150-centimetre BP Satino, while the listed metal versions of that size weigh 18.7 kilograms. These are specific product details with which mounting must be coordinated. The tile finish reveals little about the load-bearing capacity of the structure behind it.

Read more

Have the wall fixings assessed and use the prescribed components. Check where pipes run before drilling. Also maintain sufficient space to mount and maintain the model according to its instructions. A towel rail and towel must not unexpectedly restrict use of an adjacent cupboard or a clear passageway.

The appliance can become hot during use. Maintain the product clearances and minimise accidental touching through suitable positioning. Do not place additional racks, decorations or textiles over the panel beyond the intended rail application. If the layout changes later, check again that the originally required space and cable route are maintained.

Electrical configuration and the daily programme

Assessing the product and water environment together

The catalogue specifies IPX4 for the relevant BKW Plus bathroom versions. The suitable mounting location also follows from the exact manual and the specific bathroom. Have a professional assess water points, shower, bath and a possible panel position on a sketch. This connects the selection to actual conditions and applicable installation requirements.

For the models described, the catalogue lists a 230-volt connection and a 650-millimetre connection cable with the relevant plug system. The professional assesses the electrical provisions for the complete combination. If an existing water-fed radiator is removed, the old and new work must also be coordinated in advance.

Read more

The appliance’s protection rating does not automatically make its connection, cable joint or controls suitable for every position. The complete system requires an appropriate configuration. Therefore, also include the position of the thermostat and any receiver. During renovation, you can incorporate these components early in the plan, before tiling and the connection route are completed.

One room thermostat for the dual system

Our catalogue describes central control of both heating zones through one room thermostat. This enables an understandable room programme within a suitable control combination. Select the thermostat and switching equipment for the specific product. The presence of two zones in the appliance does not automatically mean that each section can be operated separately with any app or switch.

View our information about thermostats and precon connections and controls for suitable components. Have the controls, receiver and means of operation documented in the proposal. Additional functions are offered only within the capabilities of the selected combination, keeping everyday use clear.

Read more

The sensor position must comply with the mounting instructions and provide a useful indication of room temperature. Direct heat from the appliance, sunlight or a cold wall can influence the measurement. Discuss the position before setting the programme. A well-selected measurement location helps you understand operation without repeatedly changing the desired temperature.

Aligning heating periods and drying with your routine

A time programme can start before the morning routine and move to another setting afterwards. Allow for the appliance and room to warm up. If towels are still wet after showering, the desired period may be longer than the time someone spends in the bathroom. Discuss how the programme suits the model’s combined functions.

Read more

The time a towel needs varies with thickness, moisture content and how it is hung. A folded pile of textiles differs from the use for which the rail is intended. Follow the specific instructions and assess the result during your normal routine. You can then focus the programme on actual needs without treating a fixed drying time as a certainty.

Interaction with underfloor heating or another existing heat source also deserves attention. Record which provision maintains the baseline temperature and what role the towel version will have. In a dual system, room heating and drying can be connected. Understand how the selected controls respond so that expectations concerning towel use and room temperature are accurate.

Consumption, conditions and a complete proposal

Calculate using nominal output and actual duration

As a purely hypothetical example, consider a 660-watt version heating for a total of two hours at its full nominal output. Consumption is then 0.66 kW multiplied by 2 hours: 1.32 kWh. With an illustrative tariff of €0.30 per kWh, variable electricity costs are €0.396, rounded to approximately €0.40. This is a calculation example, not a prediction for your bathroom.

Compare the old and new situations against the same comfort requirement. Tariffs, heat delivered and use of other heat sources all count. The type of rail or colour of the front does not provide a general cost saving. Read our explanation of Welltherm infrared heating consumption if you want to develop your own scenario.

Read more

The active programme period is not necessarily equal to actual switched-on time. A room thermostat can switch intermittently, and conditions determine how frequently this occurs. With a combined appliance, you must also understand its specific operation before assigning consumption to one function. Nominal output belongs to the version described; without data, a separate daily cost for towel drying cannot be derived.

Including solar panels and careful maintenance

Solar panels can supply electricity during heating hours, but morning and evening use do not always coincide with generation. Include simultaneous generation, season and your own electricity contract in the calculation. The bathroom’s heating requirement remains when generation is low. Therefore, choose a system according to the function it actually needs to fulfil for your household.

Applicable Welltherm panels have a five-year warranty under the relevant conditions. Different provisions may apply to accessories. Confirm this for the selected version and rails, and view our warranty information. A warranty period is a product condition; it does not replace correct use or suitable installation.

Read more

Clean the product and rails according to their respective instructions. Let the appliance cool and use cleaning products suitable for glass, coatings or metal. Avoid putting strain on the cable, connection or fixings during cleaning. Even a smooth front needs maintenance, and a heating product is no reason to omit practical checks of installation and use.

Choosing a Welltherm bathroom towel warmer for two functions

Do you only want to dry textiles, or must the appliance also provide bathroom heating? Compare products against that task first. A compact towel dryer, a warming cabinet and a bathroom version for room heating have different functions. A low wattage on the packaging therefore does not tell you whether an appliance can maintain your bathroom’s temperature independently. We connect your towel requirements with the existing heat source and the desired new heating function.

Read more

Our BKW Plus version combines the lower drying zone with room heating above. When selecting, it is useful to describe two periods: when people need warmth and when used textiles are hung up. These periods need not coincide. Ask how the selected room controls handle this pattern and what operation you can expect from the complete combination. A separate drying programme or individual zone operation is included only when the specific version supports it.

When replacing an appliance, also include the practical role of your current radiator. Does it, for example, hold towels for several users, and which heat source will remain afterwards? With a photograph of the existing arrangement, desired rails and daily usage, we can coordinate the proposal accordingly. Then compare the complete solution against the same comfort requirements, including controls and mounting. This helps you select a towel warmer for its actual function in your bathroom.

Information that helps us substantiate your choice

For advice, we would welcome dimensions, photographs and an overview of your bathroom layout. Indicate the available wall position and water points. State how many towels you want to use, their size and when the bathroom is used. Include information about current heating and insulation so that capacity and the practical towel function can be assessed together.

View the versions through bathroom infrared heating or our shop. Prices are available on request. Ask about the complete combination of product, suitable rails and controls. We and HeatXL help document the proposal clearly, paying attention to mounting and the work assessed by a professional.

Read more

Tell us which finish appeals to you and what limitations exist. A wall you do not wish to alter, a low mounting position or a door opening wide may be important. Indicate if building details are unknown. We can then explain what is still required to complete the proposal. This keeps the advice specific and based on your room.

Choose the towel function as part of your bathroom plan

A Welltherm infrared towel radiator is selected as a specific combination of heating version and rails belonging to its range. The BKW Plus collection brings towel drying and room heating together in a dual system. Dimensions, capacity, mounting and controls then determine how these functions work effectively in your bathroom.

Frequently asked questions about the Welltherm towel radiator

Can I use any Welltherm panel as a towel radiator?

No. The towel function belongs to models designed for that purpose and suitable rails belonging to the range. An ordinary panel must not be covered with textiles. Select the complete combination and follow the exact version’s instructions for hanging and using towels.

How does the dual heating system work?

For the BKW Plus collection, the catalogue describes towel drying in the lower section and room heating in the upper section. Both zones are controlled centrally through one room thermostat. Have the specific control combination and operation for the selected product documented in the proposal.

Which dimensions and outputs are available?

The BP versions described include dimensions of 60 by 120, 60 by 150 and 60 by 180 centimetres with outputs of 550, 660 and 850 watts. The catalogue lists one, two and three possible rails. Assess the selected version according to wall space, heating requirements and towel usage.

Which towel rails are suitable?

The catalogue lists, among others, BEE0430 and BEE0550, open at one end with lengths of 43 and 55 centimetres, and the continuous 65-centimetre BEE0650. Compatibility and mounting requirements are confirmed for the selected model. Do not substitute an arbitrary accessory.

Can the appliance heat my entire bathroom?

This depends on the room and selected output. For primary heating, capacity must suit heat loss and the desired temperature. Provide window, insulation, height and ventilation details. When supplementing underfloor heating, the appliance may have a different role.

Can the towel version be mounted on the ceiling?

The bathroom versions described are intended for wall mounting. Practical rail use also requires accessibility for handling towels. Select a suitable separate ceiling model if a ceiling function is needed; do not interchange mounting methods based on a similar appearance.

What should I know about water and installation?

The relevant range lists IPX4, but the permitted position also follows from the manual and specific bathroom. Have a professional assess water points, mounting, connections and controls together. The protection rating is one product detail within the complete installation plan.

How long does drying take and what does it cost?

Drying time depends on the fabric, moisture, hanging method and conditions. Costs follow from actual electricity consumption and your own tariff. With the combined system, a fixed separate drying cost cannot be determined without additional data. Coordinate the programme with your daily routine.
