The Ultimate Guide to On-Demand Water Heaters for RVs
As RVing continues to grow in popularity, one of the most sought-after amenities is a reliable source of hot water. Traditional RV water heaters often leave you waiting for hot water to recover, especially during busy camp days. On-demand water heaters for RVs, also known as tankless water heaters, have emerged as a solution, offering instant hot water without the limitations of a tank system. This guide explores everything you need to know about on-demand water heaters for RVs, comparing different types and their applications, and providing insights you won’t find elsewhere.
Comparison of RV Water Heater Types

Understanding On-Demand Water Heaters
What is an On-Demand Water Heater?
An on-demand water heater heats water directly without the use of a storage tank. When you turn on the hot water faucet, cold water travels through a pipe into the unit, where it is heated by either gas or electricity. This means you have a constant supply of hot water, ideal for RVs where space and weight are considerations.
Benefits of On-Demand Water Heaters
-
Endless Hot Water: One of the major advantages is the ability to enjoy hot water whenever you need it. It’s perfect for families or groups who require multiple hot water sources simultaneously.
-
Space Efficiency: These units are generally more compact than traditional water heaters, freeing up valuable space in your RV.
-
Energy Efficiency: On-demand heaters only work when required, potentially saving you money on energy bills.
-
Lower Weight: By eliminating the need for a water tank, tankless systems can significantly reduce the overall weight of your RV.
Key Considerations When Choosing an On-Demand Water Heater
Fuel Type
On-demand water heaters can run on propane or electricity. Propane units are generally more powerful and can heat water quickly, making them suitable for outdoor use. Electric units are typically easier to install but may require a sufficient electrical setup in your RV.
Flow Rate
The flow rate, measured in gallons per minute (GPM), indicates how much hot water the heater can supply at once. Consider the needs of your RV usage—if you plan to shower and do dishes simultaneously, a higher GPM is essential.
Installation Space
Before purchasing, measure the installation space in your RV. On-demand heaters are compact but ensure you have enough space for both the unit and any required ventilation systems.
Safety Features
Modern tankless water heaters come with several safety features, such as overheat protection, carbon monoxide detectors, and anti-scald technology. Prioritizing safety features can provide peace of mind while camping.
