The History of the WILLER™ Brand

The history of the WILLER™ brand began during the tumultuous times of World War II when the German engineer and inventor Gerald Willer was forced to leave his homeland. In search of a new home and opportunities to realize his ideas, he immigrated to France, where he started his journey toward creating a world-renowned brand.

In France, Gerald Willer found inspiration and support to turn his engineering ideas into reality. His pursuit of innovation and excellence led to the creation of the first prototypes of water heaters, known for their high efficiency and reliability. Thanks to his talent and hard work, Willer managed to create products that quickly gained the trust of consumers.

The establishment of WILLER™ was a logical continuation of Gerald's engineering successes. From the very beginning, the brand focused on the development and production of high-quality water heaters and electric boilers.

The fundamental principle of the company's operations has always been, and remains, the combination of advanced technologies, reliability, and product durability. Over the years, WILLER™ has transformed into one of the market leaders while staying true to the quality traditions laid down by its founder.

Today, the WILLER™ brand is a symbol of innovation, energy efficiency, and comfort, reflected in every product we create. We take pride in our history and continue to move forward, implementing cutting-edge technologies to ensure your comfort and cosiness.
