Lochinvar's History dates back to 1919 with its founder Walter Vallett, Sr.'s entry into the water heater business. Mr. Vallett was a true industry pioneer, having been instrumental in the development of the first automatic gas fired water heaters early in his career. Walter Vallett, Sr. founded the Walter Vallett Company May 16, 1946. He remained committed to the industry, and active in the corporation, serving as Chairman of the Board until his death in 1982. Bill Vallett Sr. was the second-generation owner of the business and is credited with the vision for the need of higher efficiency gas appliances in the late seventies. He developed the engineering system that has designed today's line of high efficiency water heaters and boilers.
