Winterizing your RV’s tankless water heater is an important task that must be done every fall before the cold weather begins. By winterizing your tankless water heater, you will help protect it from freezing temperatures and ensure it continues operating efficiently for years. This blog post will teach you how to winterize RV tankless water heater properly.
How To Winterize RV Tankless Water Heater | Step By Step Guide
Step 1: Flush Out The Water Heater System
The first step in winterizing your RV’s tankless water heater is to flush out the system. This step is important because it helps remove sediment or debris from the system that can damage the tankless water heater over time. To flush out the system, turn off the power and open hot and cold-water shutoff valves near the RV’s tankless water heater system.
Then, turn on all hot water faucets in the RV until they run clear. Once all the hot water has been flushed out, close all the faucets and shut off the valves.
Step 2: Add An Antifreeze Solution To The System
The next step is to add an antifreeze solution to prevent any remaining water from freezing inside the tankless water heater system during cold weather. Start by disconnecting hot and cold-water lines at their respective fitting points near the tankless water heater.
To ensure that all the pipes are filled with antifreeze solution, attach a hose to one end of each pipe and submerge them in a bucket filled with an antifreeze solution. Next, turn on both hot and cold-water shutoff valves until there is a steady flow of antifreeze solution through each hose and into each pipe.
Finally, disconnect both hoses from their respective fitting points near the tankless water heater system and reconnect them back into place once all pipes have been filled with an antifreeze solution.
Step 3: Turn Off The Power For The Tankless Water Heater System
Once all these steps are complete, you should turn off all power sources for your RV’s tankless water heater system before storing it away for the winter months.
This will help prevent any potential damage due to electrical surges or other problems caused by leaving it powered on while not in use or in extremely cold temperatures throughout the winter months ahead.

Do You Have To Winterize A Tankless Water Heater?
Absolutely! Winterizing a tankless water heater is essential for ensuring it continues operating effectively and efficiently. Winterizing involves:
- Draining the heater.
- Lubricating any moving parts.
- Cleaning the filter.
- Vacuuming any debris or dust.
- Flush out any sediment build-up in the heater’s lines.
In addition to these basic steps, there are a few other tips that can help you with winterizing your tankless water heater:
1) Make sure to insulate hot-water pipes – wrapping pipe insulation around the coils of your tankless hot water system will help keep those lines from freezing up during cold weather.
2) Check for vent corrosion – inspect your vents regularly for signs of corrosion, as this can cause problems like blocked exhaust paths during cold weather months. Also, ensure these ventilation outlets are clear and unobstructed so that air can flow freely.
3) Use antifreeze – adding non-toxic propylene glycol antifreeze to all external valves on the system is highly recommended since it helps ensure freeze protection in temperatures as low as -60°F (-51°C). Be sure to follow directions carefully when using antifreeze or consult with a professional technician if needed.

4) Test pressure relief valve operation – check pressure relief valve functions by slowly opening it every couple of months (usually once or twice per year). This ensures everything operates properly and prevents potential issues due to clogged relief valves in cold weather scenarios.
5) Ensure proper drainage – always be certain that proper drainage points exist outside the home so water does not back up into the unit itself over time due to frozen exterior drains or other blockages such as leaves and grass clippings, which could disrupt flow conditions into/out of your tankless water heaters system from/to its intended destination locations (i.e., septic tanks/lines).
Following these five key steps above when winterizing your tankless water heater will ensure its efficient operation for many years!

Bottom Line:
How to winterize RV tankless water heater? Winterizing an RV’s tankless water heater is essential for ensuring its longevity throughout colder months ahead when temperatures drop below freezing levels regularly outside.
By following these steps above—flushing out any remaining sediment or debris from within your system, adding an antifreeze solution, and turning off power sources—you can rest assured that your RV’s tankless water heater will remain safe during the winter months ahead! Furthermore, repeat this process every fall before storing away for colder temperatures each year!
