Drain the Water Heater

Flush the System

Inspect and Clean the Air Intake and Exhaust Vents

Examine the vents for any debris or blockages. Clear away leaves, twigs, or any other obstructions that might impede proper ventilation. Adequate airflow is essential for the combustion process and overall performance.

By following these meticulous steps, you fortify your tankless water heater against the challenges posed by colder climates. It’s important to note that the specifics of the winterization process may vary based on the model and manufacturer guidelines.

Winterizing an Outdoor Tankless Water Heater

Winterizing Outdoor tankless water heaters require additional attention due to their exposure to the elements. Follow these extra steps to ensure they’re adequately protected:

Install a Freeze Kit

Many tankless water heaters come with a freeze protection kit. If your unit has this feature, make sure it’s properly installed. This kit typically includes a heater and thermostat to keep the internal components warm and prevent freezing.

Use Insulation

Wrap the outdoor tankless water heater with insulation material designed for this purpose. Covering the unit helps retain some heat and provides an added layer of protection against freezing temperatures.

Create a Shelter

Consider constructing a shelter or housing around the tankless water heater. This can be a simple enclosure using materials like plywood or plastic, providing an added layer of insulation and shielding it from wind and precipitation.
