2x the warranty of most tanks. Rinnai offers a 6-year warranty on the tank and 5-year warranty on all parts, components and the heat exchanger.
Reliability You Can Count On
Every Rinnai system is individually tested for quality before shipping. Unlike many competitors, Rinnai makes the majority of our key components, allowing for consistent control of quality. That’s why more consumers and businesses choose Rinnai over any other tankless brand.
