Checking and testing products before they are distributed to the market is important in showing that a product performs as intended and offers the same features as offered to consumers.  Checking and testing products secures sales success by instilling confidence with buyers and consumers, giving them a guarantee of certain standards. 

The foundation for checking and testing is to offer a certificate that certifies checks and testing have been carried out to a third party standard. This gives a quality guarantee for the product. This is achieved through a voluntary test process carried out on the product during on-site fabrication. Behind each certificate from ECOTHERM, stands the TÜV Product service gmbh, certifying that ECOTHERM has carried out the quality checks and testing deemed best practice in the industry. The TÜV is a German accreditation system with the strictest standards, respected around the world.
