1. Disconnect the water lines connected to the tankless water heater. Make sure to drain out any remaining water in the lines.
2. Disconnect any electrical cords connected to the unit.
3. Next, locate the cold water inlet valve and shut it off. This should prevent cold water from entering the tankless water heater and freezing.
4. After the inlet valve is closed, open the hot water faucets at all fixtures to allow air to enter the lines. This will help prevent a vacuum lock from developing and potentially causing damage when the hot water heater is turned back on.
5. Now it’s time to insulate the tankless water heater. Start by wrapping the exterior of the unit with a thick layer of insulation, taking care to ensure it is properly sealed. You can use pipe insulation or another suitable material for this purpose.
6. Once the tankless water heater is insulated, connect an air compressor line to the atmospheric vent and add compressed air to the unit. This will help ensure that the tankless water heater is not exposed to any water that may freeze within the unit and damage its components.
7. Finally, replace any covers to the unit and ensure that all covers are properly sealed.
By following these steps you should be able to properly winterize an outdoor tankless water heater and prevent it from freezing and damaging its components.
Where should tankless water heater not be installed?
Tankless water heaters should not be installed in spaces too small to handle the necessary venting, such as small closets or bathrooms. These types of water heaters require exhaust ventilation to prevent the combustion byproducts from entering the living space and should not be installed in an attic or any space that does not have the necessary airflow for the vent system to work effectively.
In addition, tankless water heaters should not be installed in an area where there is a risk of flooding, as the unit could be damaged in the event of a flood. Tankless water heaters also should not be installed outdoors, as the temperatures and conditions outdoors can cause problems with both the water heater and its connections.
