Why My RV On Demand Propane Water Heater Is Necessary
From my experience, having an on demand propane water heater in my RV has been a total game-changer. Unlike traditional water heaters that store hot water and can run out quickly, this system heats water only when I need it. This means I never have to worry about running out of hot water during showers or washing dishes, which is a huge convenience on the road.
Another reason it’s necessary for me is the energy efficiency. Since it only heats water on demand, it saves propane and reduces waste, helping me stretch my fuel supply longer between refills. This efficiency also means quicker hot water, so I spend less time waiting and more time enjoying my travels.
Lastly, the compact size and ease of installation make it perfect for the limited space in my RV. It frees up room and reduces weight compared to traditional tank heaters, improving my overall RV experience. Having reliable hot water anytime, anywhere truly makes life on the road much more comfortable.
My Buying Guide on RV On Demand Propane Water Heater
When I first decided to upgrade my RV’s hot water system, I quickly realized that an on-demand propane water heater was the way to go. It offers endless hot water and saves energy, which is perfect for life on the road. If you’re considering one too, here’s what I learned and what helped me choose the best unit for my RV.
Why Choose an On Demand Propane Water Heater?
I wanted a water heater that didn’t run out of hot water halfway through a shower and wouldn’t drain my propane unnecessarily. On-demand (or tankless) propane water heaters heat water only when I need it, so they’re more efficient than traditional tank heaters. Plus, they’re compact, which saved me valuable space inside my RV.
Key Features to Look For
When shopping, I focused on these important features:
- Flow Rate: This tells you how many gallons per minute (GPM) the heater can deliver. I found that around 2-3 GPM is ideal for typical RV use—enough for a shower and a faucet at the same time without a drop in temperature.
- Ignition Type: Many models use a piezo ignition or electronic ignition. I preferred electronic ignition because it’s more reliable and easier to start, especially in cold weather.
- Temperature Controls: Having adjustable temperature settings helped me avoid scalding hot water or lukewarm showers.
- Safety Features: Look for units with flame failure protection and overheating sensors. These give peace of mind when using propane appliances in a confined space.
- Size and Weight: Since space is limited in an RV, I picked a compact and lightweight unit that was easy to install and didn’t add much bulk.
Power Source and Propane Usage
I checked how much propane the unit consumes per hour at different heat settings. Efficient models use less propane, which extends my fuel supply on longer trips. Also, some heaters can run off 12V power from the RV battery to start the ignition, which is handy when shore power isn’t available.
Installation Considerations
Installing an on-demand propane water heater can be straightforward if you have basic plumbing and propane experience, but I made sure to:
- Verify the heater’s venting requirements to safely exhaust combustion gases.
- Confirm the unit fits in my existing water and propane lines or if I needed adapters.
- Check if professional installation was recommended or required to maintain warranties.
My Top Tips for Choosing the Right Model
- Read user reviews from other RVers to learn about reliability and real-world performance.
- Consider brands known for durable RV water heaters, as they often have better support and replacement parts.
- Think about your typical water usage—if you camp solo or with family—and pick a flow rate accordingly.
- Don’t forget warranty and customer service; it makes a difference if you need help on the road.
Final Thoughts
After weighing all these factors, I picked a propane on-demand water heater that fit my RV size, matched my hot water needs, and had solid safety features. It’s been a game-changer for comfort and convenience during my travels. If you’re ready to upgrade, keep these points in mind, and you’ll find a unit that makes every shower on the road a pleasure.
