If you own an RV or are thinking about buying one, you know that hot water is not just a luxury—it’s a necessity. Whether you want a warm shower after a day outdoors, or you need hot water for washing dishes, a reliable water heater makes RV life much more comfortable. One popular choice among RV owners is the Suburban Advantage RV Tank Water Heater. But many wonder: Does it have both electric and gas modes? This article answers that question in detail, explains how these modes work, compares them, and offers practical advice for anyone considering this heater. You’ll also find answers to the most common questions at the end.
Understanding The Suburban Advantage Rv Tank Water Heater
The Suburban Advantage is a line of water heaters designed for RVs, known for their durability and efficient heating. The brand has earned a reputation for providing hot water quickly and reliably, even in tough conditions. Most Suburban Advantage heaters come with a tank design—typically 6, 10, or 12 gallons—which stores hot water and delivers it on demand.
A key feature that attracts buyers is the ability to use two energy sources: gas (propane) and electricity. But not all models offer both options, so it’s important to understand which models have dual modes and what this means for your RV setup.
Electric And Gas Modes: How They Work
The Basics Of Gas Mode
Gas mode uses propane—the same fuel many RVs use for stoves and refrigerators. In this mode, a burner heats the water inside the tank. Propane is widely available and often preferred for off-grid camping, since it doesn’t rely on shore power or a generator. The gas mode is usually activated by flipping a switch inside the RV.
The Basics Of Electric Mode
Electric mode uses 120V AC power—the type you get from plugging your RV into a campground’s shore power or running a generator. An electric heating element warms the water. This mode is quiet, doesn’t produce exhaust, and is convenient when you have access to reliable electricity.
Dual Mode Functionality
Many Suburban Advantage models are dual mode, meaning you can use either gas, electricity, or both. Some RV owners use both modes at the same time for faster heating. This flexibility lets you adapt to different situations—like conserving propane or using available electric power.
Here’s a quick comparison:
| Mode | Fuel Source | Typical Use | Pros | Cons |
|---|---|---|---|---|
| Gas | Propane | Boondocking, off-grid | Works anywhere, fast heating | Uses propane, noisy burner |
| Electric | 120V AC | Campgrounds, full hookups | Quiet, saves propane | Needs power, slower heating |
| Dual | Propane + Electric | Anytime fast heat needed | Quickest heating | More energy use |
Which Suburban Models Have Both Modes?
Not every Suburban Advantage water heater offers both gas and electric modes. You need to check the model number and product details. Models ending with “DE” or labeled as “Dual Electric” have both gas and electric heating. For example, the Suburban SW6DE is a 6-gallon tank model with both modes, while the SW6D is gas-only.
Here’s a quick reference for common models:
| Model | Tank Size | Gas Mode | Electric Mode |
|---|---|---|---|
| SW6D | 6 Gallons | Yes | No |
| SW6DE | 6 Gallons | Yes | Yes |
| SW10DE | 10 Gallons | Yes | Yes |
| SW12DE | 12 Gallons | Yes | Yes |
If you’re unsure about your model, check the label near the heater, or consult your RV manual.
How To Use Electric And Gas Modes
Switching Between Modes
Most dual-mode Suburban heaters have two switches inside the RV—one for gas, one for electric. You can turn either on, or both at the same time. The switches are often near the kitchen or bathroom.
- To use gas mode, turn on the propane supply and flip the gas switch.
- For electric mode, make sure your RV is connected to shore power, then flip the electric switch.
- For dual mode, activate both switches.
Practical Tips
- Start with electric mode if you’re plugged in, to save propane.
- Use gas mode when off-grid or if electricity is limited.
- For a quick hot water boost, turn on both modes.
- Always check that the tank is full of water before heating, to avoid damage.
Common Mistakes
- Forgetting to fill the water tank before heating.
- Leaving both modes on when not needed, wasting energy.
- Not checking switches after moving between campgrounds.
Performance Data: Heating Time And Energy Use
When choosing a water heater, it’s smart to compare heating times and energy consumption. Suburban Advantage heaters are known for their efficiency, but the actual performance depends on tank size and mode.
| Tank Size | Gas Heating Time | Electric Heating Time | Dual Mode Heating Time |
|---|---|---|---|
| 6 Gallons | ~25 minutes | ~40 minutes | ~18 minutes |
| 10 Gallons | ~35 minutes | ~55 minutes | ~26 minutes |
| 12 Gallons | ~40 minutes | ~65 minutes | ~30 minutes |
These times are averages; real results may vary based on water temperature, propane quality, and electric supply.
Non-obvious insight: If you often camp in cold weather, using both modes can make a noticeable difference—hot water arrives much faster, which is important for showers and washing up.
Maintenance And Troubleshooting
Keeping your Suburban Advantage heater in good shape is vital for long-term use. Here are practical tips:
- Flush the tank every few months to remove mineral buildup.
- Check the anode rod regularly. It protects the tank from corrosion; replace it when worn.
- Inspect the burner and electric element for dirt or damage.
- Test both modes before each trip to ensure everything works.
If you notice slow heating or no hot water, check:
- Power supply (electric mode).
- Propane supply and burner (gas mode).
- Water level in the tank.
Beginner’s tip: Many RVers don’t realize that hard water can quickly damage the heater. Using a water softener or filter helps protect your tank and extends its life.
Comparing Suburban Advantage With Other Rv Water Heaters
Suburban Advantage is not the only water heater for RVs. Brands like Atwood and Girard also make popular models. Here’s how Suburban compares to others:
- Durability: Suburban tanks are made of steel with a porcelain lining, while some competitors use aluminum.
- Dual mode: Both Suburban and Atwood offer dual mode heaters, but Suburban’s electric element is generally stronger.
- Ease of maintenance: Suburban models have a replaceable anode rod, which some other brands lack.
A major advantage is the anode rod—many beginners miss that this small part can save your tank from early failure.
Is Dual Mode Worth It?
For most RV owners, having both electric and gas modes is a big advantage. Dual mode heaters:
- Give you flexibility in energy use.
- Let you save propane when plugged in.
- Offer faster heating when needed.
If you mostly camp at sites with electricity, electric mode is enough. If you travel off-grid, gas mode is essential. Having both means you’re ready for any situation.
Expert advice: If you plan to upgrade your RV water heater, look for dual mode models. The extra cost is usually small compared to the benefits.
Installation And Upgrading
Installing a Suburban Advantage water heater is usually straightforward, but you may need professional help. Here’s what matters:
- Check your RV’s power supply and propane lines.
- Make sure the heater fits your available space.
- Dual mode models need both electric and gas connections.
If you’re upgrading from a gas-only model, you may need to add wiring for the electric element. This can involve running a dedicated circuit from your RV’s breaker panel.
Beginner’s insight: Don’t forget to check the amperage of your RV’s electrical system. The electric element can use up to 1,440 watts—about 12 amps. Make sure your RV can handle this load, especially if you run other appliances at the same time.
Safety Tips For Using Both Modes
Safety is important when handling propane and electricity. Follow these tips:
- Turn off power and gas before servicing the heater.
- Check for propane leaks regularly.
- Never operate the heater without water in the tank.
- Use only approved replacement parts.
Proper installation and regular checks can prevent accidents and keep your heater working smoothly.
