Finding a tankless water heater that works for your situation can be a frustrating task, and no one wants to be purchasing one that doesn’t end up working for their specific purpose. It’s always good to do as much research as you can before purchasing a tankless water heater.
When it comes to tankless water heaters, two companies continually go toe-to-toe are Noritz Vs Rinnai. Both of these companies offer superb tankless water heater products and are similar in many ways, but it still pays to dig a little further deeper into what each company offers customers.
Rinnai is a popular manufacturer of tankless water heaters. It has many different products that work well for residential homes while still being compact at the same time. A lot of the tankless water heaters they offer are energy-star qualified. They also use some of the latest technology in the industry, such as WiFi controllable technology.
Because of these characteristics, Rinnai has made a name for itself by manufacturing the best-selling water heater throughout North America.
Hidejiro Naito and Kanekichi Hayashi founded Rinnai back in 1920. They initially started making cooking stoves over in Japan. As soon as the 1930s rolled around, they started manufacturing gas appliances. In 1964, they started gravitating towards manufacturing water heaters, and after a decade of doing that, they began an office in the United States.
