Welltherm makes infrared panels in various materials and versions. We supply these products to private customers, business end users and professional partners. A suitable choice starts with how the room is used, its heating demand and the right combination of products.
Different ranges for different applications
A metal panel, glass panel, mirror panel and bathroom version are different products. When choosing, check the exact item code and current documentation. A feature of one range does not automatically apply to the entire brand.
Compare the Welltherm product families.
The current catalogue lists IP21 for standard metal PB panels and IPX4 for the usual glass WS, SP and TA panels. Older models may have different specifications. An IP rating alone also does not determine whether an appliance may be mounted in a specific bathroom location.
What does an infrared panel do?
A warm panel emits radiant heat to the people and surfaces it reaches. Convection also occurs and the air warms up too. It is therefore incorrect to say that there is no air movement at all or that the air is never heated.
Suitability as primary or supplementary heating depends on heating demand and positioning. A fixed number of square metres at a given wattage is not a guarantee. For regular room heating, we assess heat loss; for a workstation, we also consider the irradiated zone and duration of use.
Precon and controls form a complete combination
In current panel ranges designed for it, Welltherm uses the Precon plug system with a GST15i3 connector. The connector provides the electrical connection. The thermostat and any receiver control heat demand and switching.
Check the model and connection method of an existing panel. Choose the cable, receiver and thermostat according to compatibility and permitted load. The same plug shape does not mean every controller can communicate wirelessly with every other one. A suitable connection combination must also be correctly mounted and configured.
EIHA: check the product scope
The EIHA certificate 2412-004 published by Welltherm covers the metal PB range and states validity up to and including 23 December 2026. It is not a general quality mark for all glass products, heaters and controls from the brand.
A label also does not guarantee a fixed savings percentage or a particular energy bill. For a special finish or older version, ask which documentation applies.
What information helps you choose?
- The dimensions, insulation and use of the room.
- Primary heating or local supplementary heating.
- The available wall or ceiling position and any obstacles.
- The exact panel code, connection and desired operation.
- For extensions: a photograph of the rating plate and existing connection.
With this information, we can make the proposal specific. Cleaning, inspection and any warranty conditions follow the documentation for the version supplied.
