Quick Answer
Yes, it is possible to use a portable propane water heater for camping, but it requires careful consideration of sizing, venting, and freeze protection.
Choosing a Suitable Propane Tankless Water Heater
When selecting a portable propane tankless water heater for camping, consider the size of your group and the desired hot water temperature. A typical 2.5-gallon-per-minute (GPM) model is sufficient for a small family of three to four people. Larger families will require a 4-6 GPM unit. Look for a model with a high BTU rating to ensure efficient heating, such as 40,000-60,000 BTUs.
Venting and Installation Considerations
Propane tankless water heaters require proper venting to safely exhaust combustion gases. When camping, use a flexible vent pipe or a high-temperature-rated exhaust hose to connect the heater to a safe exterior location. Ensure the vent pipe is at least 3 feet away from any windows, doors, or other combustible materials. Always follow the manufacturer’s installation instructions and local building codes.
Freeze Protection and Demand
To prevent the water heater from freezing in cold temperatures, consider installing a freeze protection kit or using a dedicated 12V or 24V heating element. This will help maintain the water temperature above freezing (32°F) when the propane is not being used. Additionally, consider the demand on the water heater, especially in the morning when everyone wants to shower. Use a timer or automatic shut-off to conserve propane and extend the heater’s lifespan.
