When I first came across the OEVANT RV Tankless Water Heater, I was immediately intrigued by its powerful 55,000 BTU rating and the promise of instant hot water tailored specifically for RV use. As someone who values both convenience and efficiency during my travels, this product seemed like a perfect match. The fact that it’s designed to be compatible with all RVs reassured me that installation wouldn’t be a hassle, no matter the type of vehicle I own or plan to use in the future.

For RVers who enjoy relaxing or need quick access to hot water at odd hours, this is a game-changer. The compact 16×16 inch door size and front water outlet design also caught my attention because they simplify installation and maintenance, which can often be a headache with larger or more awkwardly designed units.

2. Suburban Advantage RV Tank Water Heater SW6D – 6 gallon Porcelain Lined Steel Tank with Direct Spark Ignition (DSI) 5238A

When I first came across the Suburban Advantage RV Tank Water Heater SW6D, I was immediately drawn to its reputation for reliability and efficiency, especially given its 6-gallon capacity and porcelain-lined steel tank. As someone who spends a good amount of time on the road or at campsites, having a dependable hot water source is essential, and this model seems thoughtfully designed to meet those needs.

The 6-gallon tank size is a sweet spot for many RV users like me. It’s large enough to provide sufficient hot water for multiple uses—whether it’s showering, washing dishes, or cleaning up after outdoor adventures—yet compact enough to fit well within the typical RV space constraints. The porcelain lining of the steel tank stood out because it offers excellent corrosion resistance and durability, meaning the tank is less likely to degrade over time. This is a critical feature for me because I want a water heater that not only performs well but also lasts through many seasons of use.

Another feature that caught my attention is the Direct Spark Ignition (DSI) system. Unlike older pilot light models, DSI ignites the burner electronically, which is more efficient and reliable. From my experience, this means faster start-up times and fewer issues with ignition, especially in colder weather or at high altitudes where pilot lights can struggle. The convenience of having a consistent ignition system reduces the hassle and makes the overall experience more user-friendly.

While I don’t have a detailed list of the product features, the combination of a robust porcelain-lined steel tank and modern ignition technology tells me this water heater is built with both longevity and performance in mind. For anyone living in or traveling with an RV, these qualities make a significant difference in daily comfort and confidence. Knowing that I can count on hot water without constant maintenance or unexpected failures is a huge relief.

To help visualize its core specifications and benefits, here’s a quick summary

Feature	Description	Benefit
Tank Capacity	6 gallons	Ample hot water supply for typical RV needs without taking up excessive space
Tank Material	Porcelain-lined steel	Enhanced durability and corrosion resistance for longer lifespan
Ignition Type	Direct Spark Ignition (DSI)	Reliable, quick ignition with less maintenance compared to pilot lights
Model Number	5238A	Ensures you’re getting the specific, trusted configuration of the Suburban Advantage line

if you’re in the market for an RV water heater that balances capacity, durability, and modern ignition technology, the Suburban Advantage SW6D looks like a solid choice. I appreciate how it addresses the common pain points that RV owners face, such as limited space, corrosion issues, and unreliable ignition systems. While I always recommend comparing options based on your specific RV size and usage patterns, this model definitely offers features that can enhance your comfort and convenience on the road. If you want peace of mind knowing your hot water needs are covered efficiently, the Suburban Advantage SW6D deserves strong consideration.

When I first came across the RV Tankless Water Heater with a 65,000 BTU capacity and a 3.9 GPM flow rate, I was genuinely intrigued by its promise of on-demand, high-efficiency hot water tailored specifically for RV users like myself. The idea of having instant hot water without the hassle and energy waste of traditional tank heaters is a game changer, especially for those of us who value convenience and efficiency on the road. Knowing that this heater activates only when hot water is needed means it’s designed to save energy by avoiding standby losses, which is a significant plus for anyone trying to conserve propane and power during their travels.

The performance features really stood out to me. The 3.9 gallons per minute output is impressive for an RV water heater, meaning it can handle multiple uses simultaneously without running out of hot water quickly. The maximum temperature rise of 123°F ensures that even in colder climates or higher altitudes, I can expect consistently warm water. The heater’s efficiency—using about 40% less energy than traditional tank heaters—is especially appealing since it translates into extended propane usage and fewer stops to refill tanks, which can make a big difference on longer trips.

What I found particularly reassuring was the robust build quality and safety features. Crafted from stainless steel with a built-in oxygen-free copper water tank, it promises durability and resistance to corrosion, which is essential given the varied conditions RVs often face. The inclusion of a powerful yet quiet DC motor instead of an AC motor not only reduces noise but also ensures stable combustion, making my camping experience more peaceful. The multi-layered safety system, including a leakage protection switch and pressure valve to prevent tank bursting, reflects thoughtful engineering aimed at protecting both the user and the unit, which is something I personally value highly.

Installation and compatibility also seem straightforward and user-friendly. The heater’s dimensions and door size mean it can replace most existing RV water heaters without major modifications, which is a relief for someone like me who prefers hassle-free upgrades. Its connection requirements—12V DC power and propane with standard inlet/outlet sizes—are typical for RV setups, making integration smoother. The smart remote control that displays temperature in Celsius or Fahrenheit adds a nice touch of convenience, allowing me to customize my hot water experience easily without fumbling around inside the RV.

What makes this tankless water heater even more appealing is its adaptability to various environments. Its ability to run smoothly at high altitudes and use advanced segmented combustion technology to optimize flame size helps conserve propane, which is crucial for RVers traveling in remote or mountainous regions. The compact and lightweight design compared to traditional tank heaters makes it easier to carry and maneuver, which I imagine will be welcomed by anyone who frequently moves or retrofits their RV setup. Additionally, its suitability for campers, yachts, and other mobile locations broadens its usability, making it a versatile investment for those who enjoy a mobile lifestyle.

When I first came across the RV Tankless Water Heater Propane, I was immediately impressed by its thoughtful design and powerful performance tailored specifically for RV users like me. This on-demand propane gas heater is not only compatible with all RVs and campers but also features a large 16 x 16 inch door that makes installation or replacement a breeze. The size upgrade from the standard 15 x 15 inch door means it fits seamlessly, reducing the hassle that often comes with retrofitting water heaters in an RV. Plus, the smart remote control that works up to 6.6 feet away adds a level of convenience I didn’t realize I needed until I tried it—being able to adjust the water heater settings without leaving my spot is a genuine game changer.

One of the standout features for me is the constant water temperature control. The RV water heater uses high-efficiency heating coils combined with a built-in microcomputer control system to maintain a precise and comfortable temperature range between 95°F and 124°F. This means no more sudden cold shocks or scalding hot water, which can be common with older RV water heaters. I also appreciate the staged combustion technology, which not only prevents overheating during warmer months but also reduces propane consumption by up to 40%. As someone who values both comfort and efficiency on the road, this feature really speaks to the product’s intelligent engineering.

Endless hot water is a luxury that this tankless water heater delivers impressively. With a powerful 55,000 BTUs output and the ability to produce 3.9 gallons per minute, it ensures I never run out of hot water whether I’m taking a shower, washing dishes, or multitasking around the RV. The quick heating time—reaching up to 124°F in just 25 seconds—means I don’t have to wait long to enjoy warm water, which is essential when you’re trying to get ready quickly or conserve water. This feature alone makes it a significant upgrade over traditional tank water heaters that require preheating and have limited capacity.

Another aspect that really stood out to me is the heater’s high-altitude performance. If you’re like me and enjoy camping or traveling through mountainous regions, knowing that this unit is designed to function efficiently at altitudes as high as 9,800 feet (like the Denver Plateau) is reassuring. The high-quality heat exchange system and the enhanced NIDEC fan providing 300Pa of power ensure reliable hot water supply even under challenging conditions such as high winds. This level of adaptability makes it a versatile choice for various environments and travel plans.

Installation was surprisingly straightforward thanks to the comprehensive guide provided. I found the requirements clear—12-volt DC power and propane, with standard 1/2″ NPT connections for water inlet, outlet, and gas inlet. The inclusion of a 5/8″ NPT adapter for the gas inlet means compatibility with multiple setups. Of course, proper ventilation and exhaust are essential for safe operation, but the instructions made it easy to understand how to achieve this. For anyone comfortable with basic RV maintenance, this water heater’s installation will feel manageable and efficient.

Safety is always a top priority for me when upgrading any RV appliance, and this product delivers on that front with nine advanced safety features. From overheat protection and dry burn protection to flame failure and freeze protection, the heater is designed to keep you and your RV safe in a variety of situations. The anti-scald protection is particularly comforting, especially if you’re traveling with family or pets. Being CSA-certified adds an extra layer of trustworthiness, reassuring me that the unit meets rigorous safety and reliability standards.

This independence allows me to camp in more remote spots and still enjoy the comforts of home.

It’s also efficient and cost-effective, so I don’t have to break the bank just to stay warm and clean. Overall, my propane water heater gives me the freedom to live and explore on my own terms. Buying Guide for RV Water Heater Propane Understanding My Needs Before I started looking for an RV water heater that uses propane, I considered how I planned to use it. The size of my RV, the number of people traveling with me, and how often I would need hot water all influenced my choice. I knew that choosing the right capacity was crucial to avoid running out of hot water or wasting fuel. Types of Propane Water Heaters I learned there are mainly two types of propane water heaters for RVs: tank and tankless. Tank models store a set amount of hot water, which means I always had some ready but could run out if usage was high. Tankless heaters heat water on demand, providing an endless supply but sometimes with a slight delay. Understanding these differences helped me decide which type fit my lifestyle better. Size and Capacity Considerations Choosing the right size was important for me. I looked at the gallon capacity for tank heaters and flow rate for tankless units. Since I travel with my family, I needed a unit that could handle multiple showers and dishwashing without waiting too long. Overestimating slightly helped me avoid running out of hot water unexpectedly. Energy Efficiency and Fuel Consumption I paid close attention to the energy efficiency ratings of the propane water heaters. A more efficient unit meant less propane consumption, which saves money and reduces the frequency of refills. I also checked the BTU rating to understand how powerful the heater was and how quickly it could heat water. Installation and Compatibility Since I wasn’t a professional plumber, I wanted a propane water heater that was relatively easy to install or upgrade. I also made sure the heater was compatible with my RV’s existing propane system and water lines. Some models require specific venting or electrical connections, so I took note of these requirements. Safety Features Safety was a top priority. I looked for features like automatic shut-off, flame failure protection, and temperature controls. These features gave me peace of mind, especially when using the heater overnight or while away from the RV. Maintenance and Durability I considered how easy it would be to maintain the heater. Some models require regular flushing or inspections to prevent sediment build-up. I also checked the materials used in construction to ensure durability, as RV environments can be tough on appliances. Budget and Warranty Finally, I balanced the features I wanted with my budget. I set a price range that made sense for my usage without compromising on essential features. I also looked for products with good warranty coverage to protect my investment over time. Final Thoughts Buying an RV propane water heater is a decision that affects comfort and convenience on the road. By carefully considering my needs, the type and size of the heater, efficiency, safety, and maintenance, I was able to choose a unit that fits my RV lifestyle perfectly. Taking the time to research and understand these factors made all the difference in my experience. Author Profile Parker Leslie Hi, I'm Parker Leslie.
