    Rinnai has been manufacturing top quality water heaters since 1921, and they have quickly become the number one seller of tankless water heaters in the United States and Canada. Rinnai's water heaters save homeowners money by only heating water when needed, and tankless water heaters save space due to their small size compared to a tank water heater. Other models have the ability to save more money by recirculating hot water heating it to the right temperature instead of always heating cold water.
