It's no secret that the recent winter weather is proving to be anything but mild. While ensuring you and your family are protected from the elements with groceries, flashlights with batteries and warm blankets, it’s also important to protect your Rinnai Tankless Water Heater.
Freeze protection comes standard on all Rinnai Tankless Water Heaters. As long as there is both power and gas supply to the appliance, freeze protection guards against outside temperatures as cold as -22°F (‐30°C) for indoor models, or as cold as -4° F (-20° C) for outdoor models when protected from direct wind exposure. Because of the “wind-chill” effect, any wind or circulation of the air on the unit will reduce the effectiveness of freeze protection.
If the Rinnai Tankless Water Heater will be dormant during a period of possible below-freezing temperatures, it is recommended the water be drained from the unit.
If the Rinnai unit or the external piping has frozen, do not operate the tankless water heater. Instead, close the gas and water valves and turn off power to the unit. Then, contact your local service provider for assistance.
