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.

Safety, quality and service are the cornerstones of Takagi's success. We've been making tankless water heaters since 1952 worldwide. Our commitment to innovation and customer satisfaction is evidenced by the revolutionary and highly efficient tankless water heaters we've produced over the years.
