As an avid traveler and 5th wheel enthusiast, I’ve learned the importance of having a reliable hot water supply during my adventures. Traditional water heaters can be bulky and inefficient, taking up valuable space in my trailer and often running out of hot water just when I need it most. This is why I believe that investing in the best tankless water heater for my 5th wheel trailer is absolutely essential.

My Buying Guides on Best Tankless Water Heater For 5TH Wheel Trailer
When I first started my journey into RV life, I had no idea how important a reliable hot water system would be for my comfort. After some research and personal experience, I’ve come to appreciate the benefits of tankless water heaters, especially for my 5th wheel trailer. If you’re considering making the switch, I’d like to share my insights on finding the best tankless water heater for your needs.
Understanding Tankless Water Heaters
Before diving into specific models, let me explain what tankless water heaters are. Unlike traditional water heaters that store hot water in a tank, tankless systems heat water on demand. This means you get a continuous supply of hot water without the wait or the bulk of a large tank. For a 5th wheel trailer, where space is often limited, this can be a game-changer.
Key Features to Consider
- Flow Rate: One of the first things I look at is the flow rate, measured in gallons per minute (GPM). This tells you how much hot water you can expect at any given time. For my needs, I found that a flow rate of at least 5 GPM works well for showering and doing dishes simultaneously.
- Energy Efficiency: Since I live in my trailer, energy efficiency is crucial. I always check for the Energy Factor (EF) rating. The higher the EF, the more efficient the heater. I’ve noticed that units with a higher EF save me money on propane or electricity in the long run.
- Size and Installation: Space is limited in a 5th wheel, so I always consider the dimensions of the unit. Some models are more compact and designed specifically for RV use. I prefer those that can be easily mounted and have straightforward installation instructions.
- Power Source: My 5th wheel is equipped for either propane or electric water heaters, but I’ve found that propane models tend to perform better in colder weather. Depending on your setup, consider which power source is most convenient for you.
- Temperature Control: I love having precise control over water temperature. Some advanced models feature digital displays that allow you to set the exact temperature, which is something I find incredibly useful.
Top Picks for Tankless Water Heaters
After thorough research and personal usage, here are my top picks for tankless water heaters that work exceptionally well in 5th wheel trailers:
- Rinnai V65eP: This propane model offers a flow rate of up to 6.6 GPM. It’s compact, highly efficient, and perfect for my needs. The digital temperature control is a nice touch, allowing me to set my preferred temperature easily.
- Camplux 5L: If you’re looking for a budget-friendly option, this portable propane tankless water heater is fantastic. It’s lightweight, easy to install, and provides on-demand hot water with a flow rate of 1.32 GPM, which is perfect for outdoor showers.
- Ecosmart ECO 27: This electric model is powerful, with a flow rate of up to 6 GPM. It’s energy-efficient and offers great temperature control. I’ve found it to be a reliable option, especially during warmer months.
- Suburban SW6DE: A dual-source heater that runs on both propane and electric, this model is versatile. It’s designed for RVs and has a solid reputation for reliability. I appreciate the continuous hot water it provides, no matter the season.
Installation Tips
Once you choose your tankless water heater, installation is the next step. I recommend hiring a professional if you’re not comfortable with plumbing or electrical work. Ensure you follow the manufacturer’s guidelines for proper installation to avoid any issues.
Maintenance Considerations
Maintaining my tankless water heater is essential for longevity. I regularly descale my unit to prevent mineral buildup, especially when using it in areas with hard water. I also check for any leaks or corrosion during my RV maintenance routines.
Choosing the best tankless water heater for your 5th wheel trailer doesn’t have to be overwhelming. By considering flow rate, energy efficiency, size, power source, and temperature control, you can find a model that fits your lifestyle. My experiences have shown me that investing in a quality tankless water heater significantly enhances the comfort of RV living. Happy camping!
