In 1955 Oscar Bock, company founder, invented the original multi-finned flue which was patented under the name of Turboflue® in 1960. Since then, our engineers have developed and utilized this notable achievement as a strong foundation for our water heaters. Producing an outstanding product is important to Bock, that's why we're the best!

More than 100 years ago, Edwin Ruud, a Norwegian mechanical engineer, came to America and developed the first successful automatic water heater. That early success marked the beginning of a tradition of innovation and value that led to the introduction of RUUD heating and air conditioning equipment in the 1950s. Since then, the RUUD has grown into one of North America's largest manufacturers of quality heating, cooling and water heating products for residential and light commercial use.

Today, RUUD operates manufacturing facilities employing highly trained workers and state-of-the-art equipment. Over the years, the product lines have expanded, changed, and improved significantly as new design techniques and better manfacturing technologies have become available.

What remains unchanged throughout our history, however, is our commitment to producing the most reliable, long-lasting, efficient equipment you can buy.

Corporation 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. After acquiring the Michigan Tank and Furnace Company, the company name was changed to Lochinvar Water Heater Corporation. In 1978, his son William Vallett became president and grew the business through his innovation and leadership until his retirement in 1992.
