EHC Winterthur was founded in 1929 and remained as an amateur club in the Swiss Regio Leagues until earning promotion to the National League B for the first time in 1961, where Winterthur remained for two seasons before leaving. After relegation from the NLB, the club was merged with the second Winterthur club, EHC Veltheim, to form Rot-Wiess Winterthur on May 30, 1963. As a result, 1963 is also referenced as the club's foundation year.
Rot-Wiess played the following 6 years in the lower leagues before playing a lone season in the NLB in 1969. On April 22, 1980 the club returned to its original name as EHC Winterthur. In the 2009–10 season, EHC Winterthur won the Swiss amateur champion title, but due to lack of financial backing opted not to participate in the NLB.
