View on Amazon

Pros:

When you’re on the road, the last thing you want to worry about is whether you’ll have hot water for your shower. Enter the Poukaran 65,000 BTU RV Tankless Water Heater ,  a game-changer for anyone looking for reliable, on-demand hot water while traveling. This unit promises uninterrupted hot water, which is perfect for long days when multiple showers are a must. Thanks to its propane-powered heating, it guarantees consistent performance without the need for electricity. So, whether you're camping or parked at a remote site, you'll have the luxury of hot water anytime, anywhere.

Its high performance technology is impressive too. Equipped with a 65,000 BTU output and a copper heat exchanger, it can handle high-altitude conditions and ensures energy efficiency. This is especially beneficial in warmer months when other systems may struggle with overheating. Whether you're in the mountains or at sea level, you can rely on this heater to work seamlessly.

For added convenience, the dual water outlets are a standout feature. Whether you're using the internal outlet for daily showers or the external one for outdoor needs like bathing pets, it’s versatile enough to meet all your water demands. The ease of use is also fantastic; with an adjustable temperature range from 95°F to 123°F and a microcomputer control panel, you can customize your experience to perfection.

Cons:

On the flip side, the unit’s size might be a concern for RV owners with tight spaces. The 15 x 15-inch door required for installation could be tricky to fit in certain RV models, especially those with smaller or more compact setups. While this water heater is designed for high-altitude use, it may not be the best choice for users in areas where temperatures frequently drop below freezing, despite the built-in freeze protection.

Another minor drawback is the reliance on propane for heating. While this ensures that electricity shortages won't be an issue, it also means you’ll need to have a steady propane supply to keep it running, which could be an inconvenience if you're not close to a refill station.

Lastly, while the microcomputer control panel makes it easier to troubleshoot and adjust settings, it might take a little time to get used to. For those unfamiliar with high-tech controls, there might be a slight learning curve to understand the error codes and how to fix any minor issues that arise.

Despite these drawbacks, the Poukaran RV tankless water heater remains a solid choice for anyone looking to elevate their RV experience with reliable, high-performance hot water. Whether you're camping, traveling, or living full-time in an RV, this system delivers exactly what it promises: endless hot water and peace of mind on the go.

Pros:

If you’re tired of waiting for hot water in your RV, the Ranein 65,000 BTU RV Tankless Water Heater could be the answer to your prayers. This on-demand hot water heater promises an end to those awkward, cold showers. With a maximum output of 3.9 gallons per minute (GPM), it ensures that you’ll never be left shivering while you wait for water to heat up. Whether you’re enjoying a long shower after a hike or washing your hands after a day’s work, this tankless water heater delivers consistent, reliable hot water all day long.

Its upgraded multi-function remote control is another great feature. It allows you to monitor gas usage, water pressure, voltage, and even see if the anti-freeze device has been activated. This level of control means you can stay informed about your water heater’s performance and keep it running efficiently, especially in more demanding conditions like high altitudes. With 65,000 BTUs and a high-altitude capability, the Ranein RV water heater excels in ensuring hot water availability even in rugged or chilly environments, so you can enjoy comfort wherever you go.

With staged combustion technology, this unit ensures that the temperature remains steady, between 95°F to 124°F, regardless of the external weather conditions. The pressure relief valve and intelligent controller included make it even more convenient, saving you from additional installations and making your setup hassle-free. Plus, the built-in forced exhaust fan provides a stable combustion environment, while the automatic gas shut-off offers peace of mind when it comes to safety.

Cons:

Despite its many upsides, the Ranein tankless water heater does have a few drawbacks. First off, it requires a 12V RV system, so if you’re not using a compatible voltage, this unit won’t work for you. While it’s easy to replace existing Suburban or Atwood water heaters, the fitting door kit isn’t included with the unit. You’ll need to purchase this separately, which can be an inconvenience and add to the cost.

Although it boasts an anti-freeze device, users in freezing temperatures may still need to be cautious. The auto-activation of the anti-freeze feature kicks in at temperatures below 42.8°F, but you’ll need to ensure your RV is adequately protected and maintained during extremely cold conditions. For some, this might feel like a safety gap, especially if the environment reaches temperatures quickly before the device has time to respond.

Finally, while the quick-heating feature is impressive, the size of the unit (12.8 x 12.8 inches without the door) could be an issue for RVs with limited installation space. Although it replaces Suburban and Atwood models, the need for an additional door purchase (sold separately) can create some frustration for users looking for a completely ready-to-go solution.

In conclusion, the Ranein RV Tankless Water Heater offers great value for anyone seeking a reliable, efficient water heating solution for their RV. With its high performance, user-friendly features, and safe operation, it's a top choice for those looking to enhance their travel experience with on-demand hot water. Just keep in mind that it requires a little extra setup and investment for doors, and always be mindful of extreme cold temperatures.

Pros:

For RVers who prioritize reliability and durability, the Suburban Advantage RV Tank Water Heater SW6D stands out as a great choice. Engineered with a porcelain-lined steel tank, it mimics the longevity of residential water heaters, offering the durability needed for the rough-and-tumble RV lifestyle. This feature not only ensures years of hot water but also guarantees it can handle the wear and tear typical of road travel.

One of the key highlights of this unit is its advanced corrosion protection. The replaceable anode rod is a game-changer when it comes to extending the life of your water heater. Not only does the rod prevent corrosion inside the tank, but it also functions as a drain for easy maintenance. This simple yet effective design keeps the unit running smoothly while reducing the hassle of upkeep.

Flexible power options are also a significant benefit with this model. The option to use either gas or electricity for heating provides unparalleled versatility, allowing you to use campground power or your generator to get hot water. Whether you're plugged in at a campsite or relying on propane while off-grid, the Suburban Advantage can adapt to your needs, making it a solid choice for RVers with varying power sources.

The exclusive heat transfer technology is another standout feature. Suburban's flue tube design slows the combustion process, optimizing heat transfer and ensuring water heats up efficiently. This not only saves energy but also provides quicker access to hot water, so you won't be left waiting when you need it most. With a recovery rate of 10.1 gallons per hour for gas heating, this model can handle multiple uses in a short amount of time, ideal for RV families or those who enjoy long, hot showers.

Cons:

Despite the many benefits, the Suburban Advantage RV Tank Water Heater SW6D does come with a few limitations. First, while the 6-gallon capacity is adequate for most RVers, larger families or those needing more hot water may find it a bit limiting. It may not be ideal for extended periods of hot water use without a longer recovery time.

Additionally, while the replaceable anode rod is an excellent feature, it does require some attention to maintenance. Though it's designed for easy replacement, this maintenance step may not be ideal for those who prefer a truly hassle-free experience. Regularly replacing the rod is crucial to maintaining the efficiency and longevity of the unit, which could be inconvenient for some RV owners.

The optional electric element input is a fantastic feature, but it does require additional setup and investment. If you're looking for a quick, plug-and-play solution, the need for an electric element (which isn’t always included) could add complexity and cost. Depending on your RV setup, you might also find the cutout dimensions slightly restrictive, requiring some adjustments during installation.

Lastly, while the 2-year limited warranty is a decent safety net, some RV owners might prefer a longer term for peace of mind, especially given the wear and tear that water heaters endure over time. The 3-year tank limited warranty is a nice touch, but it’s still shorter than some competitors in the market.

Overall, the Suburban Advantage RV Tank Water Heater SW6D is a robust, well-designed option for those looking for a reliable and versatile solution to hot water needs in their RV. While it may require a bit more attention to maintenance and installation, its combination of durability, energy-efficient heating, and dual power sources make it a standout choice for the road.

Pros:

If you're seeking a reliable, durable water heater for your RV, the Suburban Advantage RV Tank Water Heater SW10DE is a strong contender. Engineered with a porcelain-lined steel tank, it’s designed to stand up to the rigors of RV life, offering a lifespan that mirrors the longevity of residential water heaters. Whether you’re camping for a weekend or embarking on a cross-country adventure, this 10-gallon water heater guarantees consistent hot water, so you won’t have to worry about running out during a shower or washing dishes.

One of the most impressive features of the Suburban SW10DE is its advanced corrosion protection. The replaceable anode rod is not just a feature; it’s a game-changer in keeping the tank in top condition. The rod prevents corrosion, ensuring that the water heater performs optimally for years. Plus, the rod doubles as a drain, which makes maintenance a breeze ,  no extra tools needed, and no messing around with complex setups.

Flexibility is another major benefit of this model. It includes an optional electric element, which allows you to switch between propane and electric power sources. This is incredibly useful when you're hooked up to campsite power or using a generator. Having the option to use either power source gives you the freedom to tailor your water heating method depending on your available resources, whether you're off-grid or plugged in.

The exclusive heat transfer technology is also a big win. With Suburban's innovative flue tube design, the combustion process is slowed down, optimizing heat transfer and making sure the water heats up quickly without wasting fuel. The energy-saving features of this water heater allow it to provide hot water faster, and with its 10.1 GPH recovery rate (gas only), it's built to handle high-demand situations, like when multiple people need hot water at the same time.

Cons:

As fantastic as the Suburban SW10DE is, it does come with some drawbacks. For instance, its size can be a bit challenging in RVs with limited space. With dimensions of 16.22" x 16.22" x 20.50", it may require some adjustments during installation, especially if you’re replacing an older or smaller unit. The cutout dimensions (16.38" x 16.38" x 20.50") are slightly larger than its predecessors, so installation may not be as simple as a direct swap.

Another consideration is the optional electric element. While the option to use electric power is great for versatility, it also means the unit isn’t a complete plug-and-play solution. The electric element isn’t always included, and some users may find the additional cost and installation process a hassle, especially if they’re not familiar with how to wire it correctly. However, once installed, the system can work seamlessly with both propane and electricity, making it very versatile.

The recovery rate of 6.1 GPH (electric only) may not be enough for heavy-duty use if you have a large family or often host guests. While it provides 10.1 GPH (gas only), when running on electricity, the slower recovery rate could be a limitation if you need hot water quickly or in high volumes. This might require you to be a bit more strategic about when and how you use the water heater.

Finally, while the 2-year limited warranty is decent, some may find it a bit short for a product that’s supposed to handle the heavy-duty demands of RV life. The 3-year tank warranty is better, but given how much this water heater is relied upon, a more extended coverage period would offer better peace of mind for RV owners.

The Suburban Advantage RV Tank Water Heater SW10DE remains a top choice for those seeking a reliable, efficient, and long-lasting solution for hot water on the road. With its durable construction, advanced features, and flexibility in power options, it offers both convenience and peace of mind, especially for those who need consistent performance during their travels.

Pros:

For RV owners, campers, and food truck operators seeking reliable and compact hot water solutions, the Feelrogast Electric Tank Water Heater-8 Gallon offers a fantastic combination of power, efficiency, and durability. With its rapid reheat capabilities, this mini-tank heater heats water almost instantly, drastically reducing waiting time. Whether you're trying to get ready for a shower or need hot water on demand for washing dishes, it delivers quickly, making it an ideal choice for those with limited time and space.

One of the standout features of the Feelrogast heater is its 316 stainless steel heating element, which ensures up to 99% heat utilization. This means that you're not wasting energy – the system is highly efficient, which helps keep your power consumption low while delivering reliable hot water. Plus, the temperature range of 86-167°F provides flexibility, allowing you to set the heat to your precise preferences. From a quick rinse to a long soak, you’ll have just the right amount of heat.

Safety is another key selling point. This electric tank heater is CE, ROHS, and FCC certified, meaning it's built to meet the highest safety standards. The 1.88mm thick stainless steel tank is designed to be pressure-resistant and explosion-proof, offering peace of mind during use. Its multi-layer insulation and leakage protection plug ensure that the unit stays safe under varying conditions, making it a reliable option for travel and remote locations where safety is paramount.

Installation is a breeze as well. The wall-mount, rack, or floor-mount options give you flexibility depending on the space available in your RV, camper, or kitchen. Plus, with 1/2" NPT water connectors and a 44-inch power cord, setting it up is straightforward and easy, making it ideal for users who may not be familiar with complex installations. The 20-amp breaker requirement ensures that the unit runs safely and efficiently, preventing electrical mishaps.

Cons:

While the Feelrogast Electric Tank Water Heater excels in many areas, it’s not without its limitations. For one, the 8-gallon capacity might not be enough for larger families or RVs with high water demands. If you have multiple people using hot water at the same time, the tank might not provide enough to meet the need without a bit of waiting for it to reheat. While it’s great for smaller showers or basic kitchen needs, it could leave you wanting more during longer stays or when hosting multiple guests.

Another point to consider is that while the 110/120V and 1440W setup is efficient for most typical uses, it may not be powerful enough to handle more intensive applications. If you plan on using the heater for larger tasks, such as running multiple appliances simultaneously, you may find that the recovery rate isn’t quite as fast as larger, more robust systems.

The Feelrogast heater is designed to be compact and space-saving, but that comes at the expense of larger water volume, which may be a dealbreaker for some. The unit is ideal for under-sink installation, but if you need more than the 8 gallons, you might have to explore other options. Additionally, while the unit’s design is sleek and compact, it’s not as portable as some other models meant specifically for RVs. If you need to move it frequently or have a fluctuating need for hot water in various areas, its fixed installation setup may not be as flexible as you’d like.

Lastly, while the safety features are comprehensive, including high-temp limiting devices and auto temperature control, the reliance on electricity limits the operability in off-grid situations where electrical access is sporadic or unavailable. If you primarily depend on propane or solar power while camping, this unit may not align with your energy sources, as it’s specifically designed for 120V electrical outlets.

The Feelrogast Electric Tank Water Heater-8 Gallon is an excellent choice for those seeking a reliable, space-saving, and efficient solution for their hot water needs. It’s particularly well-suited for RVs, campers, kitchens, or smaller spaces that don’t require large volumes of hot water. While it’s compact and offers a variety of safety features, users with high-demand water needs or those in off-grid locations might find it limiting. Still, for those looking for instant hot water with minimal waiting time, it’s a standout option that combines efficiency and safety in a convenient, easy-to-install design.
