External Rinnai Tankless Water Heaters are a great choice for colder climates. The external units offered by Rinnai Tankless contain a freeze protection system that will prevent the system from outside temperatures as low as -22 degrees Fahrenheit. In order for the freeze protection system to work properly, the unit must be installed where it will not be subject to direct wind exposure, and it must be supplied with power and gas at all times. To prevent against freezing damage in case of a power outage, Rinnai’s external units can be equipped with a drain down system. If the system loses power, the water will drain from the system, preventing frozen pipes or other damage.
