Choosing the Best Tankless Water Heater for Your RV Adventure
Upgrading your RV with a tankless water heater brings endless hot showers, no matter where your travels take you. Unlike bulky traditional heaters, tankless units heat water on demand. This guide helps you pick the perfect one for your mobile home.
Key Features to Look For
When shopping, keep these important features in mind. They control how well the heater works for your needs.
1. Flow Rate (GPM)
The flow rate tells you how much hot water the heater produces each minute (Gallons Per Minute, or GPM). RVs often need between 1.5 to 2.5 GPM. If you want to run two low-flow showerheads at once, aim for a higher GPM.
2. Temperature Control
Look for precise digital temperature controls. This lets you set the exact temperature you like, preventing scalding. Some basic models only offer high/low settings.
3. Ignition Type
Most RV tankless heaters use electronic ignition. This means you need a reliable 12-volt power source (your RV battery) to start the burner. Ensure the ignition system is durable.
4. Fuel Source
The best units run on propane (LP gas). Check that the heater is designed to work efficiently with the propane system already in your RV.
Important Materials and Build Quality
The materials used directly impact how long your heater lasts and how well it resists the bumps of travel.
- Stainless Steel Components: Look for stainless steel heat exchangers. This material resists corrosion and handles high temperatures well. Good quality stainless steel lasts longer.
- Durable Casing: The outer casing should be robust metal, not thin plastic. This protects the internal parts from vibration and road debris.
- Sealed Burner Box: A well-sealed unit keeps moisture and dust out, which protects the electrical components.
Factors That Improve or Reduce Quality
Quality isn’t just about parts; it’s about performance under stress.
Factors That Improve Quality:
- High BTU Rating: A higher British Thermal Unit (BTU) rating means the heater can heat water faster, especially in cold weather or when you need higher flow.
- Anti-Freeze Protection: Some premium models have built-in low-voltage heating elements or drain plugs that help prevent freezing if you store your RV in cold climates.
- Quiet Operation: Better engineering often results in quieter burners. You do not want a loud roar every time someone washes dishes.
Factors That Reduce Quality:
- Oversizing or Undersizing: Buying a heater too small for your needs leads to lukewarm showers (reduced quality). Buying one too big wastes propane.
- Poor Ignition Reliability: If the heater frequently fails to light, the overall experience drops significantly. Cheap igniters often fail first.
- Complex Installation: Units requiring extensive modifications to existing plumbing or venting reduce the overall quality of the upgrade process.
User Experience and Use Cases
Think about how you use your RV. This dictates the best unit for you.
For weekend campers who only need quick showers, a basic 1.8 GPM unit might work fine. If you are a full-timer or travel with a family, you need a heater that handles simultaneous use, like running the kitchen sink while someone showers. Choose a model rated for 2.5 GPM or higher for these scenarios.
Installation is usually easier if you replace an existing RV water heater, as the propane and venting lines are often close by. Always ensure the unit fits the space available in your utility compartment.
Tankless Water Heater for RV: 10 Frequently Asked Questions (FAQ)
Q: How much propane does a tankless RV heater use compared to a tank heater?
A: Tankless heaters use less propane overall because they only burn fuel when you need hot water. Tank heaters constantly use fuel to keep the stored water hot.
Q: Can I use any brand of tankless heater in my RV?
A: No. You must use a model specifically designed for RV use. Home tankless heaters require different venting and operate at different gas pressures than RV units.
Q: Do I need a special battery setup for a tankless heater?
A: Yes. Since the ignition system is electronic, you need a reliable 12-volt DC power source (your RV battery) to start the unit. A strong battery bank is essential.
Q: How long does hot water last when using a tankless heater?
A: Hot water lasts indefinitely! The heater only stops producing hot water when you turn off the faucet or run out of propane.
Q: What is the typical lifespan of a quality RV tankless water heater?
A: Well-maintained, high-quality tankless units often last 15 to 20 years, significantly longer than traditional RV tank heaters.
Q: Will a tankless heater work if my RV is only using city water pressure?
A: Most RV tankless heaters require a minimum water pressure (usually around 20 PSI) to activate the flow sensor. If your campground water pressure is very low, the heater might not turn on.
Q: Is installation difficult for a DIYer?
A: Installation involves plumbing, electrical (12V), and gas line connections. If you are comfortable working with propane and plumbing, it is manageable. Otherwise, hire a certified RV technician.
Q: What happens if the temperature setting is too high?
A: If the temperature setting is too high, the water can scald you. Always start with a moderate setting, like 105ยฐF, and slowly increase it until you find a comfortable temperature.
Q: Do these heaters need winterizing?
A: Yes. Even models with some freeze protection need to be properly drained or have RV anti-freeze run through them before long periods of storage in freezing temperatures.
Q: What is the difference between point-of-use and whole-house RV units?
A: Whole-house RV units (the kind we discussed) are powerful enough to supply the entire RV. Point-of-use units are small heaters installed directly under a single sink.
