When I first came across the OEVANT RV Tankless Water Heater, 55,000 BTU model, I was immediately intrigued by its promise of instant hot water and compatibility with all RVs. As someone who spends a lot of time on the road, I know how important it is to have reliable and efficient hot water without the usual wait or hassle. This unit’s compact 16×16 inch door size and front water outlet design seemed like a thoughtful touch that would fit well into most RV layouts, making installation and daily use much simpler.

One of the standout features that truly impressed me was the instant hot water supply. The fact that this water heater can reach 51°C in less than 25 seconds means no more waiting around for preheating, which is often a frustration during early morning showers or when multiple people need hot water in quick succession. This efficiency not only saves time but also conserves propane, since it only heats water on demand. For me, this is a huge practical advantage, especially when traveling off-grid where resources are limited.

The high-performance technology behind the OEVANT unit reassured me about its reliability and safety. It uses advanced staged combustion technology to maintain stable water temperatures and prevent overheating, which is crucial for comfort and safety. The fact that it operates on propane gas rather than relying solely on electricity also means I don’t have to worry about power outages or draining my RV’s batteries. This dual-power approach is a smart solution for RV users who need consistent hot water regardless of their power source.

Ease of use is another big plus. The built-in microcomputer control panel allows me to easily adjust the temperature anywhere between 95 and 123 degrees Fahrenheit. Having precise control over water temperature means I can customize my shower experience perfectly. Plus, the system’s error codes are a thoughtful feature that can help diagnose any issues quickly without needing to call for professional help right away, which is a real benefit when on the road.

The compact and convenient design really fits the needs of RV users like me. The 16-inch by 16-inch door and 13-inch by 13-inch opening make it easy to install in limited spaces, and the front-mounted water outlet is ideal for quick rinses, pet baths, or even cleaning gear without hassle. It’s clear that the designers considered practical everyday use in an RV environment, which adds a lot of value to this product.

Safety features provide an extra layer of confidence. The built-in forced exhaust fan ensures stable combustion and prevents dangerous gas buildup. Anti-freeze protection means it can handle colder climates without damage, and automatic gas shut-off in case of flame failure gives me peace of mind that the unit will protect my family and RV at all times. These thoughtful safety mechanisms make the OEVANT water heater a trustworthy companion on any adventure.

Finally, the promise of endless hot water with 55,000 BTUs of power means the whole family or group of friends can enjoy continuous hot showers without any drop in temperature or flow. The ±1℃ intelligent thermostat keeps things consistent, which means no surprises during your shower. Knowing that it’s CSA certified and compatible with all RVs and campers further assures me that this is a quality, reliable product designed with the RV lifestyle in mind.

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 robust construction and thoughtful design tailored specifically for RV users like myself. The 6-gallon porcelain-lined steel tank stands out as a major plus because it offers a level of durability that mirrors residential water heaters, which means I can count on it to deliver reliable hot water for years without worrying about premature wear or damage. This is especially important when you’re on the road and need consistent performance from your equipment.

One feature that really impressed me is the advanced corrosion protection. The replaceable anode rod is a clever addition that helps protect the tank from rust and corrosion, which is often the downfall of many water heaters over time. What’s even better is that this anode rod doubles as a drain, making routine maintenance simpler and less of a hassle. For someone like me who values longevity and ease of upkeep, this means less downtime and more peace of mind knowing the heater is well-protected from internal damage.

The flexible power options are another highlight. Being able to switch between gas and electric power (with the optional electric element) means I’m not limited by my power source. Whether I’m hooked up to a campsite’s electrical supply or relying on my generator, I can still heat water efficiently. This versatility is incredibly convenient, especially during extended trips or when camping in areas where gas may not be readily available. It’s a feature that truly adapts to different situations and needs.

I also appreciate Suburban’s exclusive heat transfer technology. The unique flue tube design slows down the combustion process, which optimizes heat transfer and results in water heating more efficiently. This means I get hot water faster while saving energy—a combination that benefits both my comfort and my wallet. Faster recovery rates and energy savings are critical when living on the road, where every bit of efficiency counts.

Looking at the specifications, the compact size (12.69″ x 12.69″ x 19.19″) fits well within typical RV tank compartments, and the 12,000 BTU/h rating promises powerful performance. The optional electric element offers a 1,440-watt input, with recovery rates of 10.1 gallons per hour on gas and 6.1 gallons per hour on electric power, which provides flexibility depending on the power source. Plus, the peace of mind from a 2-year limited warranty and a 3-year tank warranty reinforces the quality and reliability of this product.

One of the most exciting aspects is the endless hot water supply. Producing 55,000 BTUs and delivering 3.9 gallons per minute means I can take multiple showers, wash dishes, or even multitask without worrying about running out of hot water. The rapid heating time—reaching 124°F in just 25 seconds—means no more waiting around for the water to warm up, which is a huge time saver when camping or on long trips. This instant heating capability makes the RV experience much more comfortable and practical.

Another impressive detail is its high-altitude performance. Living or traveling in mountainous regions, I know how equipment can struggle with thinner air and cooler temperatures. This heater’s high-quality heat exchange system and enhanced NIDEC fan delivering 300Pa of power ensure it runs reliably even at elevations like the Denver Plateau at 9,800 feet. This means I can confidently take this water heater with me anywhere, knowing it won’t falter in challenging conditions or windy environments.

4. RV Tankless Water Heater,65000 BTU,3.9 GPM High Efficiency RV Constant Propane Tankless Water Heater, DC 12V Power, On Demand Instant Hot Water Heater,Multi-Protection for RVers’ Everyday Use

When I first came across the RV Tankless Water Heater with 65,000 BTU and 3.9 GPM high efficiency, I was immediately intrigued by its promise of on-demand instant hot water, especially designed for RVers like myself who value both convenience and energy savings. This product clearly targets mobile lifestyles, and its features align perfectly with what I need during my travels. The fact that it operates on propane with DC 12V power means it’s tailored for off-grid or limited power environments, making it an ideal companion for anyone constantly on the move in an RV, camper, or even a yacht.

One of the standout features I appreciate is the tankless design. Unlike traditional water heaters that continuously heat and maintain a tank of hot water—often wasting energy—the on-demand heating coils in this unit activate only when hot water is needed. This means I am using about 40% less energy, a significant saving especially when relying on limited propane supplies during extended trips. With a water pressure requirement as low as 3.6 PSI and an impressive 3.9 gallons per minute output, it’s capable of meeting most everyday hot water needs without lag. The ability to raise the water temperature by up to 123°F ensures that even on chilly mornings, I get a satisfying hot shower or wash.

Efficiency is vital when living on the road, and this RV water heater delivers on that front. Its 65,000 BTU maximum power output is substantial for a tankless system, ensuring hot water is available whenever I need it, provided there is sufficient gas and water supply. The lack of standby energy losses, which I find common with storage water heaters, means I don’t have to worry about wasting propane when the heater isn’t in use. This efficiency not only reduces fuel costs but also extends the duration I can stay off-grid without refilling propane tanks.

Another aspect that impressed me is the compatibility and ease of replacement. The heater fits a standard 12.6″ x 12.6″ opening and comes with a 15″ x 15″ door, making it a straightforward swap for many existing RV water heaters. Its low noise operation and vibration resistance are thoughtful design elements, especially important when living in close quarters where noise can be a nuisance. Knowing it is crafted for caravans and similar mobile environments reassures me that it will withstand the bumps and vibrations of travel without performance degradation.

Safety and reliability are paramount when dealing with propane and hot water systems, and this unit has me covered. Made from stainless steel, it boasts high temperature and corrosion resistance, promising longevity even in harsh mobile settings. The inclusion of a built-in oxygen-free copper water tank and a powerful DC motor adds to its stable, quiet combustion operation, which is less prone to noise and mechanical issues than AC motors. Features like a leakage protection switch and a smart remote control displaying temperature in both Celsius and Fahrenheit provide peace of mind and user-friendly control, making it easy to monitor and adjust settings without hassle.

Installation and daily use seem manageable, provided some basic setup requirements are met. The heater connects to standard 12-volt DC power and propane, with convenient 1/2″ NPT water connections and a 3/8″ NPT gas inlet. The built-in pressure valve is a thoughtful safety feature that releases excess pressure and drains water to prevent tank rupture—a critical safeguard when living on the road. It’s important to note that proper ventilation and exhaust are necessary for safe operation, which is standard but worth remembering to maintain safety and performance.

Lastly, the wide range of applications makes this water heater a versatile choice. Its portability and smooth operation even at high altitudes mean it performs well regardless of location, whether in mountainous regions or coastal areas. The advanced smart segmented combustion technology that adjusts flame size to prevent overheating is an intelligent energy saver that prolongs propane usage. Whether I’m RVing, camping, or on a yacht, this heater promises reliable, efficient hot water without the bulk and energy waste of traditional tank heaters.

It’s a small upgrade that really enhances my overall RV experience. Buying Guide for Propane RV Water Heaters Understanding the Importance of a Propane RV Water Heater When I started traveling in my RV, having a reliable water heater was essential. A propane RV water heater ensures I have hot water for showers, cleaning, and cooking without relying on electricity, which can be limited at campsites. It offers convenience and comfort during my trips. Types of Propane RV Water Heaters I learned there are mainly two types: tank-style and tankless. Tank-style heaters store a set amount of hot water, while tankless models heat water on demand. Choosing between them depends on my usage habits and space availability in my RV. Capacity and Size Considerations I had to consider how much hot water I typically use. For solo travel or couples, a smaller capacity suffices, but for families or longer trips, a larger tank or tankless heater with higher flow rates works better. Also, I checked the physical dimensions to ensure the heater fits in my RV’s designated space. Heating Efficiency and Recovery Rate Efficiency matters because it affects propane consumption and how quickly hot water is available again after use. I looked for heaters with good recovery rates to minimize waiting times between uses, especially during busy mornings. Power Source and Ignition Type Even though propane is the main fuel, I noted that some models require a 12V power source for electronic ignition, while others use a manual pilot light. Considering my RV’s electrical setup helped me choose a compatible ignition type. Safety Features Safety was a top priority for me. I made sure the heater has features like flame failure protection, overheat sensors, and proper ventilation requirements to prevent accidents and ensure safe operation inside my RV. Installation and Maintenance I considered how easy it would be to install the heater myself or if I’d need professional help. Maintenance requirements, like cleaning burners and checking for leaks, also influenced my decision to keep the unit running smoothly during my travels. Cost and Budget Balancing cost with features was important. I set a budget but remained flexible to get a durable and efficient water heater that meets my needs without overspending. Warranty and Customer Support Finally, I checked the warranty period and customer support reputation. Knowing help is available if something goes wrong gives me peace of mind during my adventures. Final Thoughts Choosing the right propane RV water heater improved my travel experience significantly. By considering my water usage, RV space, and safety, I found a solution that keeps my trips comfortable and hassle-free. Author Profile Parker Leslie Hi, I'm Parker Leslie.
