The company founder, Johann Vaillant, had a vision to distinguish himself as the supplier of a branded product.
In 1899, he registered the “Easter bunny in an egg” brand as a trademark and this has decorated the company’s products and catalogues ever since.
Boasting a history of over 100 years, today the brand is one of the oldest registered trademarks in Germany. Over the years, the logo has been redesigned many times, and it took on its current appearance in 2005.
Today the bunny logo is the most well-known heating technology brand in Europe. Seven out of ten consumers in Germany, Austria and the Netherlands are familiar with Vaillant’s mascot.
