RV camping is a fun outdoor adventure. But it is not all fun because it also comes with challenges, such as needing hot water for showers and washing dishes. Luckily, there is a propane tankless water heater for RV. This is enough to make RV camping more fun and convenient. Tankless instant water heaters are a relatively recent innovation in the RV industry, yet they have fundamentally changed the way we experience hot water onboard an RV.
If you are an outdoor enthusiast wanting to level up your camping experience with a heater, this guide is perfect for you. Discover more about propane tankless water heaters for RV and explore five of the best options out there. But before everything, let’s first get to know about what a propane tankless water heater for RV really is.
What is a Propane Tankless Water Heater for RV All About?
In situations where hot water is needed on demand, propane tankless water heaters for RVs offer an innovative solution. Operating on propane gas, they provide more efficient water heating than traditional electric water heaters.
Typically containing 6 or 10 gallons of water, most RV tankless water heaters can quickly deplete when multiple individuals are showering. However, with an RV hot water heater on demand, heated water is only produced when needed.
Unlike tank-style water heaters that must constantly heat the water in their tanks, on-demand RV hot water heaters precisely heat the water required, conserving fuel. Basically, this means they only need to maintain water at a set temperature once it’s used, resulting in overall lower propane consumption.
How Does a Propane Tankless Water Heater Function?
The propane tankless water heater for RV’s primary function is heating water on demand. Unlike conventional water heaters, it does not maintain a full reservoir of heated water at a constant temperature throughout the day. Instead, it operates most effectively when there is a continuous flow of water through the appliance and into the faucets. Upon turning on the heated water knob, both the RV kitchen faucet and the propane tankless water heater begin operating.
Setting up a propane tankless on-demand water heater is simple; all that’s needed is to connect the unit to a power source and ignite the pilot lamp. Once you’ve set your preferred temperature, the pilot light ignites and heats the water as it flows through the unit.
Moreover, because there’s no reservoir to maintain heat over time, propane tankless water heaters for RVs typically reduce propane gas costs. Furthermore, this design allows you to access as much heated water as needed, assuming your RV has a continuous water supply.
Tips on How to Choose the Most Appropriate Propane Tankless Water Heater for an RV
When choosing a propane tankless water heater for an RV, several factors should be taken into consideration. Here are some of them:
Certification:
Ensure that the model you choose is certified for use in recreational vehicles, as not all tankless water heaters are designed for this purpose.
Dimensions:
Consider the size of the unit in relation to your RV. RV tankless water heaters come in various configurations, so it’s essential to select one that fits your vehicle. A smaller RV may not require a large tankless water heater. On the other hand, a larger RV will likely need a larger unit.
Climate:
Take into account the weather conditions in which you plan to use your RV. If you’ll be traveling in colder climates, you’ll need a different type of tankless water heater than someone traveling in milder conditions. RV tankless water heaters are available as propane or electric models, so choose the one that best suits your needs.
Consultation:
Before making a purchase, consult with an experienced installer. They can help you choose the optimal model for your RV and ensure proper installation. This ensures that your tankless water heater functions efficiently and effectively while on the road.

FAQs
How much propane does an RV tankless water heater consume?
Some RVers opt for electric tankless water heaters because the gas models are inefficient in propane consumption. Gas RV tankless water heaters have higher BTU ratings and consume more propane than conventional water heaters.
How many gallons of water can a 100-pound propane tank warm?
A 100-pound propane cylinder can contain 23.6 gallons. The output is 2,159,447.2 BTUs. 16-gallon water purifiers are the largest to be found in an RV. We know that one gallon of propane produces 91,502 BTUs per hour. One BTU is required to elevate one pound of water one degree Fahrenheit.
This means that one gallon of propane can heat one pound of water by more than 1,500 degrees Fahrenheit per minute. You don’t want to dissolve your shower, but it’s comforting to know that propane can do so.
How long do propane tankless water heaters for RV last?
If you adequately maintain your RV water heater, it could last up to ten years. Utilizing an anode rod and ensuring that the tank is drained during winterization will help to preserve and prolong the life of your RV water heater.
How does a tankless water heater save money in a recreational vehicle?
Everything that is energy-efficient saves money. The conventional water heater continuously heats and stores water using either propane or electricity. This indicates an expense to you. However, a tankless water heater only heats water on demand, allowing you to save money. Eventually, your initial investment in your trailer’s hot water tank heater is offset by the energy savings it provides.
Can an RV tankless water heater be fixed beneath a sink?
Under basins, tankless water heaters for motorhomes can be installed. If it’s a requirement for your purposes, check the manual for each model to ensure it’s possible. You should consider electric alternatives rather than propane tankless water heaters.
Conclusion
Hopefully, finding a high-quality and worth-buying propane tankless water heater for an RV becomes easier with this guide. Upgrading your old water heater can bring significant benefits, enhancing the enjoyment of your RV experience for both yourself and your fellow travelers. The advantages of a tankless water heater are especially evident for full-time RVers and those with large families. With a tankless water heater, campers can enjoy one of the most luxurious conveniences: a highly efficient, continuous supply of unlimited hot water on demand.
