What Is Winterization?
Winterization, when it comes to tankless water heaters, refers to the process of preparing the unit for the cold winter months. This involves draining the water from the entire system, disconnecting pipes, and taking other precautions to prevent any remaining water from freezing and causing damage.
Winterizing your tankless water heater is crucial because, unlike traditional tank-style water heaters, these units do not have a reserve of water stored inside. Instead, they heat water on-demand as it passes through the unit. This means that any water left inside the pipes or components of a tankless heater is susceptible to freezing when temperatures drop.
If that water were to freeze, it could cause significant damage to the internal components of the heater, leading to costly repairs or even the need to replace the entire unit. Proper winterization helps you avoid these problems and ensures your tankless water heater is ready to provide hot water throughout the winter season.
How To Winterize Tankless Water Heater
Winterizing a tankless water heater is a straightforward process, but it’s important to follow the steps carefully to ensure the job is done correctly. Let’s go through the key steps:
Step 1: Turn off the power and gas.
Begin by turning off the power and gas supply to the tankless water heater. For the power, unplug the unit or switch off the circuit breaker. For gas, locate the main shut-off valve on the gas line and turn it to the closed position.
Step 2: Allow the unit to cool down.
If the tankless water heater has been in use recently, allow the water inside to cool completely before proceeding. Handling hot components could result in burns, so safety should be the top priority.
Step 3: Shut off the water supply.
Locate the main water shut-off valve that supplies water to the tankless heater and turn it to the closed position. This will prevent any more water from entering the system.
Step 4: Open taps to drain the system.
Turn on the hot and cold water taps connected to the tankless heater. This will allow the water already in the system to drain out completely. You may need to use a bucket to catch the draining water.
Step 5: Disconnect the water pipes.
Once the system is fully drained, disconnect the incoming and outgoing water pipes from the tankless heater. This will ensure no water remains in the pipes connecting to the unit.
Step 6: Remove the water filter.
Many tankless water heaters have an inlet water filter. Remove this filter and set it aside to dry completely.
Step 7: Blow out the remaining water.
Some manufacturers recommend using an air compressor to blow short bursts of air through the inlet and outlet connections. This helps to ensure that no residual water remains inside the tankless heater.
Tips on How to Winterize Tankless Water Heater
After completing these steps, your tankless water heater is now properly winterized and protected from freezing temperatures. Be sure to refer to your specific manufacturer’s instructions, as there may be additional steps or considerations for your particular model.
It’s worth noting that while many modern tankless water heaters have built-in freeze protection features, they still rely on electricity to function. In the event of a power outage, this freeze protection may not be effective. Winterizing your tankless heater manually is the best way to ensure it remains safe and operational throughout the winter months, even if the power goes out.
If you have an outdoor tankless water heater or one installed in an unheated area like a garage or shed, winterization is even more crucial. These units are more susceptible to freezing temperatures and require extra attention to prevent damage.
By following the steps outlined above, you can effectively prepare your tankless water heater for the winter season. This simple maintenance task can save you from costly repairs and ensure that you and your family have access to hot water whenever you need it, even during the coldest days of the year.
Winterizing your tankless water heater is easy when you know what to do.
Remember, if you’re unsure about any part of the winterization process or you don’t feel comfortable performing it yourself, it’s always best to consult with local plumbers or the manufacturer of your tankless water heater. They can provide guidance and ensure the job is done correctly, giving you peace of mind throughout the winter.
