Rinnai America has signed on as a multi-year sponsor of the NASCAR XFINITY Series race at Atlanta Motor Speedway, beginning with the 2017 race in March. The race will be named the Rinnai 250. “Not only will this sponsorship help us continue to drive consumer awareness of Rinnai tankless water heaters, but it also will provide us with a venue to showcase our products and strengthen our relationships with our valuable trade partners,” Rinnai COO Frank Windsor said.
