Ensuring Year-Round Comfort: How to Prevent Outdoor Gas Portable Water Heater from Freezing

How to Prevent Outdoor Gas Portable Water Heater from Freezing

--As the seasons change and temperatures drop, outdoor activities such as camping, hunting, and outdoor showers become less inviting due to the fear of cold water. But with the help of outdoor gas portable water heaters, you can enjoy hot water even in the great outdoors. However, to keep your water heater functioning optimally during the colder months, you need to take precautions to prevent it from freezing. In this blog post, we'll guide you through the essential steps to ensure your outdoor gas portable water heater remains operational all year round.

Choose the Right Location

Selecting the right location for your outdoor gas portable water heater is crucial in preventing freezing. Find a spot that is sheltered from strong winds and direct exposure to harsh weather conditions. Placing it near a wall or within a windbreak can provide the necessary protection from the elements.

Insulate the Water Lines

One of the primary ways to prevent freezing is to insulate the water lines leading to and from your water heater. Use foam pipe insulation or heat tape to wrap the water lines. This added layer of insulation will help maintain the water temperature within the lines and protect them from freezing.

Drain and Disconnect When Not in Use

When you're not using your outdoor water heater during the winter months, it's a good practice to drain the water and disconnect it from the propane source. This minimizes the chances of any residual water freezing inside the unit or the water lines. Be sure to follow the manufacturer's instructions for proper drainage and disconnection procedures.

Use a Frost-Free Hose Bib

A frost-free hose bib is an excellent investment to prevent freezing. These outdoor faucets are designed to automatically drain water away from the spigot, making it less likely to freeze. By connecting your water heater to a frost-free hose bib, you can safeguard your unit from extreme cold temperatures.

Employ a Weather-Resistant Cover

To further protect your outdoor gas portable water heater from freezing, consider using a weather-resistant cover designed for your specific model. These covers help shield the unit from snow, ice, and other harsh weather conditions, providing an extra layer of insulation.

Check for Leaks and Maintenance

Regular maintenance is key to ensuring the long-term functionality of your outdoor water heater. Inspect the unit for any leaks or damage, and fix any issues promptly. Check the propane connections for leaks and replace any worn-out hoses. Keeping your unit in good working condition is essential for preventing freezing and ensuring a steady supply of hot water.

Monitor the Weather Forecast

Staying informed about the weather conditions is crucial, especially when you plan to use your outdoor water heater. If you anticipate extreme cold temperatures, it's a good idea to postpone your outdoor activities or take extra precautions, such as providing additional insulation.


An outdoor gas portable water heater can be a game-changer for outdoor enthusiasts and those in need of hot water in remote locations. However, protecting it from freezing is essential for year-round functionality. By choosing the right location, insulating water lines, using a frost-free hose bib, employing a weather-resistant cover, and performing regular maintenance, you can ensure your outdoor water heater stays operational in all seasons. With these precautions in place, you can enjoy hot water no matter where your adventures take you.
