The CE marking is an administrative symbol for the European Single Market. It declares that the product to which it is affixed fulfils all the requirements for the EC directives for this product. The CE marking is essentially not a consumer mark. It serves first of all as an “EC passport” for a product and means that this product may be put on the market in every Member State within the EC. CE signals the compliance with requirements for the guarantee of safety as well as the protection of health and the environment.


The VDE certification mark for electrotechnical products is awarded by the German Association for Electrical, Electronic and Information Technology (VDE). It denotes conformity with VDE regulations or European or internationally harmonised standards and confirms compliance with the protection requirements of the applicable guidelines. The VDE mark certifies compliance with high safety standards for electronic devices, for example concerning electrical, mechanical and toxic aspects.


The seal Safety Checked (GS mark) certifies a product ready for use that complies with the requirements of § 21 of the Product Safety Act (ProdSG). In contrast to the CE marking, the GS mark can be affixed voluntarily. It postulates a successful test, certifying that the product complies with the statutory requirements for product safety. The product subsequently undergoes regular controls. The test is conducted, for example, by the TÜV.


Electrotechnical products must not only work properly and thus be safe and interference-resistant. They must also not influence any other devices while in operation or cause prohibited circuit feedback. The VDE-EMC mark confirms that the marked products fulfil all requirements set by the standards for electromagnetic compatibility (EMV).


RoHS is the abbreviation for “Restriction of Certain Hazardous Substances”. The RoHS EC Directive serves to limit the use of certain hazardous substances in electric or electronic equipment. It regulates the use and placing on the market of hazardous substances in electric equipment and electronic building elements. This single market directive applies to all EC Member States.

Made in Germany

The designation Made in Germany is purely a designation of origin and was originally introduced at the end of the 19th century as a means of protection against imported or plagiarised goods. Fundamentally, the designation “Made in Germany” requires manufacture in Germany. Nowadays the seal is seen as a seal of approval. It confirms that the product is of a quality that conforms with German value concepts.

DIN EN ISO 9001:2015

At the beginning of 2017 Welltherm GmbH received the quality management certification according to the new worldwide valid norm DIN EN ISO 9001: 2015. The ISO 9001 quality management norm is the most common nationally and internationally norm in the quality management of modern companies. This means that Welltherm GmbH is one of the few manufacturers within the infrared heating sector who have a certification.
