About Welltherm: technology, production and HeatXL

A product family gives your selection direction but does not tell you everything about an individual model. Dimensions, outputs and weights may differ within a series. Material choice can also relate to the available finish. Examine the article code of the version you are actually considering. Include the information on electrical connection, protection rating and mounting. A name such as glass, metal or designer heating does not replace those specific details.

The current catalogue provides an overview of the range. The manual for a specific appliance provides instructions for mounting and using that appliance. A brochure with lifestyle images may have a different publication date or show earlier versions. That is useful background, but an old product photograph should not be used to establish the current connection or supplied items. When extending an existing panel installation or replacing a component, photographs of the rating plate and existing installation help us.

When comparing, distinguish what the image shows from what the documentation establishes. An image may show a colour and position. Usually, you cannot infer output, IP rating or permitted bathroom zone from it. A bracket or receiver that appears to fit in a photograph must also match the chosen series. This distinction makes product selection more concrete and prevents a lifestyle impression unintentionally serving as installation instructions.

The metal PB series shows why an article number matters. PB0330 has an output of 330 W and dimensions of 59.2 × 59.2 cm. PB0510 provides 510 W at 59.2 × 89.2 cm. PB0710 provides 710 W at 59.2 × 119.2 cm. These details help compare versions but do not independently establish which model your room needs. For that, we consider heating demand, the available mounting position and the installation layout.

A sequence of increasing outputs does not mean the largest panel is the best choice in every situation. Sometimes a room needs output distributed across several positions. In another situation, reach towards a fixed occupied location matters most. Weight and the available supporting surface also play a role. A heating plan translates these details into a practical product selection. Only then do you finalise the finish and controls.

A glass panel can have a different appearance from a metal version. Various finishes and functions are available within the glass families. A heated mirror, for example, has its own role in the interior. With a chalkboard or image panel, you combine the heating appliance with a visible surface that suits the room. Consult the product page for your preferred version to determine which dimensions and options are available.

Depending on the series, our metal panels are available in white, Sand, Graphit, RAL colours and image finishes, among others. The current catalogue describes the surfaces of metal RAL and image panels as silk matt. A colour on a screen is not automatically identical to the final material appearance. Discuss the desired version and available sample when colour is an important part of your project. Product selection belongs to the interior design but remains a technical choice too.

With a personal image, you want to know in advance how it will be applied to the chosen dimensions. Consider the photograph’s aspect ratio, important details and any cropping. A small source file may not provide enough detail for a large visible surface. Include image preparation in your discussion about the panel. Image rights and suitable file submission also belong in that preparation. The possibilities of the relevant version determine what can ultimately be supplied.

A panel may suit a wall beautifully, but its position must also fit the purpose of the heating. A large cupboard or curtain can affect reach towards the intended occupied location. For a ceiling position, height and the model’s mounting possibilities matter. Make a floor plan with furniture and the places where you actually sit or work. This gives a better picture of the application than empty room dimensions alone.

Accessories can change the arrangement. A lighting frame has its own product details and protection rating. A towel rail belongs to the series intended for it. A recessed frame must match the panel and the structure in which you want to use it. These components do not automatically become suitable for the same mounting position because they belong to one design. We discuss the combination as a whole so appearance and application are coordinated.

An electric infrared panel converts consumed electricity into heat. Its heated surface emits radiant heat towards people and surfaces within reach. Heat transfer to the air and warming the surroundings also play a role. The sensation at a seating position and the measured air temperature are therefore not the same quantity. A panel first becomes warm; the whole building does not immediately reach a new temperature when you switch on the appliance.

ESHC Plus is a heating technology used in several current product series. The presence of that technology does not make every panel’s material construction identical. A drawn cross-section of a metal version, for example, is not a general cross-section of every glass variant. Use technical images in their relevant product context. They help explain a construction, while the chosen model’s documentation determines which specifications to use for your own installation.

The technology also does not change the energy balance of direct electric heating. A resistance system produces approximately one kWh of heat per kWh of electricity. A heat pump also draws heat from its surroundings and can therefore deliver more heat per kWh of electricity consumed. Which solution suits you depends on the building, application and use. Our panels can form part of a considered choice for room or local heating, but do not constitute a general savings promise for every home.

A quality document provides information within a particular scope and validity period. Check which product, organisation or assessment the document concerns. Our EIHA document relates to the metal panels in the PB series. This does not mean every accessory and glass version automatically carries the same label. When choosing a specific version, you can consider the quality label alongside model data and the application for which you need heating.

The available ISO 9001 document is a historical version with a validity period that ended on 5 April 2026. No renewed certificate is currently available in this document collection. We therefore present that version with its date and expiry, rather than attaching a current certification claim to it. A quality management document must also be distinguished from a product label and from instructions for a specific installation.

Document checks also matter for mounting and control brochures. Product names, versions and functions may differ between older and newer documents. For an existing appliance, find the appropriate manual; for a new selection, check the current catalogue. A filename alone is insufficient. If you are unsure which document belongs to your appliance, include its article code with your enquiry. We can then direct you to the right source.

First tell us which room you want to heat and what role the panels will have. Specify dimensions, height, insulation and existing heating. State whether you want to serve a single workstation, a bathroom at set times or a larger part of the building. A photograph and floor plan help discuss mounting options. These details form the basis for assessing products, output and distribution across the room.

We choose controls in relation to the panels and zones. A room with its own operating schedule requires different coordination from several independently used rooms. Our control series have specific protocols and compatible components. A connector or a general word such as wireless does not tell you which control works with which receiver. Article number, electrical load and the desired control method must be correct together.

Also have the electrical installation’s preparation requirements assessed. Consider connection points, existing circuits and cable routes. A suitable panel may still require preparation of the room where you want to use it. Discuss maintenance access too, especially with fixed finishes and suspended ceilings. The installer and model instructions determine the specific implementation. A clear component list shows what the proposal includes and what must be arranged separately.

Before contacting us, make a short list of what is settled and what remains open. Perhaps you have chosen a desired RAL colour but have not yet determined the panel position. Or the available wall is clear, while you are deciding between primary and supplementary heating. Mention future changes to insulation, layout or room use too. These details may change the assumptions behind the advice. A clear distinction between wishes and existing constraints helps compare versions purposefully and determine the project’s next step.

Check a proposal for completeness. Are panels, mounting components and controls identified? Is it clear which rooms or occupied locations are included? Also ask which assumptions were used for output and daily use. When comparing two proposals, their starting points must match sufficiently. A difference in panel price alone says little if one combination includes additional components or a different capacity.

A selection does not have to be final for the whole building immediately. You can discuss an individual application while considering possible later expansion. Record which components must remain compatible and which other zones you want to add in future. This allows you to invest purposefully in the current objective without using an unclear future plan to justify components you do not need now.

If you want to view a finish or panel first, find a suitable dealer location and contact it in advance. Not every retail partner displays every product. Ask about the version you want to see and visiting arrangements. HeatXL is located at Spoorstraat 7 in Roosendaal; this head office is not a public showroom. An appointment with the right location gives you more certainty than visiting an address without arranging it first.

A demonstration helps you experience materials and warmth, but does not automatically predict performance in your home. The demonstration room may have different height, insulation and starting temperature. Use the visit to ask about positioning, controls and the difference between radiant comfort and room heating. Include your own room data in subsequent advice. This connects the experience to a concrete product selection.

After purchase, keep product data, documentation and your seller’s agreements. The model, proof of purchase and a clear description of the situation are useful for a service enquiry. Warranty conditions may differ between panels and accessories. A five-year statement for certain panels is not a general commitment for every component. Consult the conditions relevant to your purchase and discuss any enquiry with the seller concerned.

With our range overview, product documentation and a personal proposal for your room, you can prepare the next step. We connect our products’ design with the conditions in which you will use them. A suitable version results from that combination of technical data, daily use and clear installation agreements.
