Types of Tankless Water Heaters
Propane vs. Electric
When selecting a tankless water heater for your RV, consider whether you prefer a propane or electric model. Each comes with its own set of advantages and disadvantages.
Propane Tankless Water Heaters

Electric Tankless Water Heaters
- Pros: Easier to install, no need for propane refills, and often more energy-efficient.
- Cons: Slower heating times, especially in colder weather, and reliant on electrical hookups.
Sizing Considerations
Selecting the right size tankless water heater is crucial. The size you need depends on your hot water usage. For instance, if you plan to take long showers or run multiple appliances simultaneously, opting for a larger capacity model is wise.
Benefits of RV Tankless Water Heaters
Endless Hot Water Supply
One of the major benefits of tankless water heaters is the endless supply of hot water. Unlike traditional models, where you have to wait for the tank to refill and heat up, tankless options provide hot water as long as you need it.
Space Efficiency
Tankless water heaters are typically compact and can be installed in various locations within your RV, saving precious storage space. This is particularly advantageous for RVers who prioritize a minimalist setup.
Energy Savings
Tankless models only heat water when needed, reducing energy consumption. This efficiency can save you money on fuel bills over time, making it a financially savvy choice for frequent travelers.
Longer Lifespan
Tankless water heaters generally have a longer lifespan than traditional units, often lasting over 20 years with proper maintenance. This durability can be a significant factor in your investment decision.
