Many RV owners want hot water on the road, and the Suburban Advantage RV tank water heater is a popular choice. But before you buy or use one, you might wonder: *Does the Suburban Advantage RV tank water heater run on propane?* The answer is important, especially if you travel far from electric hookups or need to understand your energy choices. Let’s explore how this water heater works, its fuel options, benefits, and what you should know to get the most from your RV’s hot water system.
Understanding The Suburban Advantage Rv Tank Water Heater
The Suburban Advantage series is designed specifically for RVs. These water heaters are known for their reliability, fast heating times, and ease of use. Suburban has been a leader in RV water heating for decades, and its models are found in many trailers, motorhomes, and campers.
Unlike small tankless or point-of-use heaters, the Suburban Advantage typically uses a tank (often 6, 10, or 12 gallons). This gives you a steady supply of hot water, which is great for showers, dishwashing, and more. But the real question is: *How does it heat the water inside the tank?*
Does It Run On Propane?
Yes, the Suburban Advantage RV tank water heater does run on propane. In fact, propane is the main energy source for most models in this line. Some models also have electric heating elements, but propane remains the core fuel for heating water quickly when you’re camping away from the grid.
Here’s how it works:
- Propane gas is ignited in a small combustion chamber under the tank.
- The heat transfers to the water through a steel or aluminum tank wall.
- Hot water is then stored until you need it.
If you have a dual-fuel model, you can also run the heater on 120V AC electricity when plugged into shore power. But propane remains the most flexible and widely used option for RVers who camp in places without electric hookups.
Propane Vs. Electric Operation
Let’s compare propane and electric heating for the Suburban Advantage water heater. Each has its strengths, and the best option often depends on your camping style.
| Feature | Propane Operation | Electric Operation |
|---|---|---|
| Heat-up speed | Faster | Slower |
| Power source needed | Propane gas (no electricity needed) | 120V AC shore power |
| Use in remote areas | Yes | No (unless generator) |
| Operating cost | Propane cost | Usually included in campground fee |
| Noise | Some burner noise | Very quiet |
| Common in models | All Suburban Advantage | Most 2-way models |
If you rely on boondocking (camping without hookups), propane is essential because it works anywhere you have gas. Electric-only heaters are only useful when you’re plugged in.
How Much Propane Does It Use?
The amount of propane a Suburban Advantage water heater uses depends on several factors:
- Tank size (6, 10, 12 gallons)
- Water temperature rise
- Frequency of use
On average, heating a 6-gallon tank from cold to hot (about 100°F temperature rise) takes roughly 0. 2 to 0. 4 pounds of propane. A standard 20-pound propane tank can heat the water dozens of times before running empty.
For example, if you take two hot showers per day, plus some dishwashing, you might use 1–2 pounds of propane daily for water heating. This is a small part of your total RV propane use, but it’s smart to track your fuel if you camp off-grid for long periods.
Key Features Of The Suburban Advantage Propane Water Heater
Suburban has designed its Advantage line with RVers in mind. Here are some features you’ll find in most models:
- Porcelain-lined steel tank – Resists corrosion and extends tank life.
- Anode rod – Protects tank from rust, making it last longer.
- Direct spark ignition (DSI) – Easy push-button or switch start, no matches needed.
- Fast recovery – Propane models can reheat water quickly, so you’re not waiting long between showers.
- Safety features – Automatic shut-off for flame-out, overheat, and pressure.
- Dual fuel (on some models) – Option to switch between propane and electric operation.
These features make the Suburban Advantage a strong choice for both beginners and experienced RVers.
How To Operate A Suburban Advantage Water Heater On Propane
Using the propane function is straightforward, but there are important steps to follow for safety and efficiency:
- Check propane supply – Make sure your tank is filled and the valve is open.
- Turn on water heater – Use the switch or DSI control panel inside your RV.
- Listen for ignition – A faint click or whoosh indicates the burner is lighting.
- Wait for hot water – It usually takes 10–20 minutes to fully heat the tank.
- Monitor water temperature – Most models have a preset thermostat, but you can test water before use.
Always keep an eye out for leaks, strange smells, or error lights. If you suspect a problem, turn off the unit and check the owner’s manual.
Maintenance Tips For Propane Models
Proper care extends the life of your water heater and keeps it running safely.
- Replace the anode rod every 1–2 years, or when 75% worn.
- Flush the tank every season to remove sediment.
- Inspect propane lines for cracks or leaks.
- Test the igniter to ensure reliable starts.
- Check the vent for blockages or insect nests.
Neglecting maintenance can lead to poor performance, leaks, or even dangerous conditions.
Common Problems And Troubleshooting
Even reliable heaters like the Suburban Advantage can have issues. Here are some common propane-related problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| No hot water | Empty propane tank, igniter failure | Check propane level, inspect igniter |
| Won’t ignite | Air in gas line, bad DSI board | Cycle unit, reset, purge air |
| Water smells bad | Tank needs flushing | Flush and sanitize tank |
| Burner flame is yellow | Dirty burner, low pressure | Clean burner, check regulator |
| Water too hot | Thermostat stuck | Replace thermostat |
If you’re not comfortable with repairs, a qualified RV technician can help.
Safety Precautions When Using Propane
Propane is safe when used correctly, but it’s highly flammable. Always follow these precautions:
- Never operate the water heater while refueling propane.
- Check for leaks regularly using soapy water at connections.
- Keep vents clear of debris, insects, or snow.
- Do not store flammable items near the heater.
- Turn off the heater before driving, unless your RV manual says it’s safe.
A good carbon monoxide detector in your RV adds extra safety.
Non-obvious Insights For New Rv Owners
- Running both propane and electric together (“dual mode”) heats water much faster. If you have shore power and propane, using both at once can cut reheat time in half. Many beginners miss this trick and wait longer for hot water.
- The anode rod is often forgotten. Many owners don’t know it exists, but replacing this cheap part saves your tank from costly corrosion.
- Propane water heaters are less sensitive to low voltage than electric ones. If your campground has unstable power, propane mode is more reliable.
Is The Suburban Advantage Water Heater Right For You?
If you camp off-grid or want the freedom to heat water anywhere, a propane-powered water heater is a smart choice. Suburban Advantage models are reliable and easy to maintain, with good support and parts availability. If you mostly stay at campgrounds with hookups, consider a dual-fuel model for more flexibility.
Some RVers prefer tankless water heaters for endless hot water, but tank models like the Suburban Advantage are less prone to cold weather problems and easier to repair.
Alternatives To Propane Water Heaters
While propane is the standard, there are other RV water heating options:
- Electric-only water heaters – Good for full hookups, not for boondocking.
- Tankless on-demand systems – Save space, endless hot water, but often need more power and are sensitive to water pressure.
- Hybrid systems – Combine heat from engine coolant (motorhomes) with propane or electric.
Each has pros and cons. For most RVers, propane remains the most practical fuel.
Cost Of Operating A Propane Water Heater
Propane prices vary, but as of 2023, one gallon costs about $2. 50–$4. 00. A gallon of propane contains around 91,500 BTUs. Most 6-gallon Suburban heaters use 8,800–12,000 BTUs per hour.
If you heat a 6-gallon tank twice daily, you’ll use about 0. 4 pounds of propane (or 0. 1 gallons) per day, costing roughly $0. 25–$0. 40 each day for hot water. This cost is quite low compared to running an electric heater with a generator.
Environmental Considerations
Propane is a clean-burning fossil fuel. It produces fewer greenhouse gases than gasoline or diesel but is not carbon-free. If you want to reduce your footprint, use hot water sparingly and keep your heater well maintained for best efficiency.
