#4: When Low on Water
When your RV’s freshwater supply is running low, it’s essential to conserve water to avoid damage to the water heater’s components. Using a water heater without sufficient water can lead to costly repairs.
To save water, try taking shorter showers or utilizing campground facilities. Another option is to invest in a portable water tank to have extra freshwater available. Remember that traveling with a full freshwater tank adds weight to your RV, reducing fuel efficiency and safety.
What Are the Pros and Cons of Leaving RV Water Heaters On?
If you’re considering whether or not to leave your RV water heater on, there are some pros and cons to weigh before making a decision.
Let’s go ahead with the pros first:
Keeping the water heater on ensures that hot water is readily available whenever you need it. You don’t have to wait for the water to heat up before using it, which can be particularly beneficial when you’re on the go or have limited time.
- Comfort During Cold Weather
Leaving the water heater on can help maintain a comfortable living environment by providing consistently hot water for showers camping in colder climates. Having steaming water available can keep temperatures inside your RV comfortable in the winter months.
Let’s move on to the cons:
- Energy Consumption
Keeping the water heater constantly running can consume a significant amount of energy. This can be a concern if you’re camping off-grid or if you want to conserve energy to extend your battery life or reduce fuel consumption.
- Propane Usage
Most RV water heaters operate on propane. And leaving the water heater on means continuous propane consumption. This can deplete your propane supply more quickly, requiring more frequent refills or affecting the overall duration of your propane reserves.
- Risk of Accidents
Leaving the water heater on increases the risk of accidents, particularly if you’re not present in the RV or if there’s a malfunction. There is a possibility of leaks, overheating, or even fires if the water heater is left unattended for an extended period.
