Is The Suburban Advantage Rv Tank Water Heater Worth It?
Traveling in an RV means mixing comfort and adventure. One thing that can make your trip more enjoyable is hot water—whether for showers, dishes, or just washing your hands on a chilly morning. The Suburban Advantage RV Tank Water Heater is a popular choice for many RV owners. But is it really worth the price and installation effort? Let’s break down what makes this water heater stand out, where it shines, where it might fall short, and what to consider before making your decision.
What Is The Suburban Advantage Rv Tank Water Heater?
The Suburban Advantage line is made for recreational vehicles and small campers. These water heaters use a tank (usually 6 or 10 gallons) to store and heat water, so you have hot water ready when you need it. Suburban is a trusted brand in the RV industry, known for durability and solid customer support.
These heaters are available in gas-only and gas/electric combo models. Most use LP gas as their main fuel, with some models able to switch to electric power when RV park hookups are available. The porcelain-lined steel tank and anode rod are designed to reduce rust and extend the heater’s life—a key selling point for many.
Key Features And Specifications
Here’s a closer look at what you get with a Suburban Advantage RV Tank Water Heater:
- Tank sizes: 6 or 10 gallons
- Fuel options: LP gas (propane) or gas/electric combo
- Recovery rate: 10.2 gallons per hour (gas), 6.1 gallons per hour (electric)
- Dimensions: About 12.5” H x 16.4” W x 18” D for the 6-gallon model
- Ignition: Manual (pilot light) or direct spark ignition (DSI)
- Tank lining: Porcelain with replaceable anode rod
- Pressure relief valve for safety
Let’s compare the main Suburban Advantage models:
| Model | Tank Size | Power Source | Recovery Rate (GPH) | Ignition Type |
|---|---|---|---|---|
| SW6DE | 6 gal | Gas/Electric | 10.2 (gas) / 6.1 (electric) | Direct Spark |
| SW10DE | 10 gal | Gas/Electric | 10.2 (gas) / 6.1 (electric) | Direct Spark |
| SW6P | 6 gal | Gas Only | 10.2 (gas) | Manual Pilot |
This range of options means you can choose a heater that fits your RV’s size and your camping style.
Performance: How Well Does It Heat Water?
A big reason people choose the Suburban Advantage is its fast recovery rate. With the gas burner, you can get hot water ready for use again in about 10–15 minutes after the tank empties. The electric element is slower but useful when hooked up to shore power, helping you save propane.
One feature that stands out is the anode rod. This small part pulls rust away from the tank, protecting it from corrosion. It’s a simple detail that can add years to your water heater’s lifespan—something beginners often overlook. Many competitors use aluminum tanks, which don’t allow for anode rods and can corrode faster.
Here’s a simple comparison of Suburban’s gas and electric heating:
| Heating Method | Recovery Time (6 gal) | Energy Efficiency | Best For |
|---|---|---|---|
| Gas Burner | 10–15 min | High | Boondocking, fast showers |
| Electric Element | 30–40 min | Medium | RV parks, saving propane |
In real-world use, most RVers find they can take quick showers back-to-back without major issues. With the 10-gallon model, a couple or small family can use hot water for dishes and showers with fewer interruptions.
Installation And Maintenance
Installing a Suburban Advantage RV Tank Water Heater is a moderate DIY project if you’re comfortable with plumbing and basic wiring. Many RVers hire a professional to ensure safety and warranty coverage. The heater fits in a standard 12” x 16” cutout, common in most RVs.
Maintenance is a strong point. The anode rod should be checked and replaced once a year, or whenever it’s more than 75% worn. Flushing the tank every few months prevents buildup and keeps water quality high. Suburban’s design makes these tasks easy, with parts widely available at RV supply stores.
One insight that new owners miss: winterizing the water heater is critical. If you camp in cold climates, always drain the tank before freezing weather arrives. Failing to do this can crack the tank and void your warranty.
Pros: What Makes The Suburban Advantage A Good Choice?
- Strong build quality – The porcelain-lined tank and replaceable anode rod mean long service life.
- Fast hot water recovery – Up to 10.2 gallons per hour means less waiting.
- Multiple fuel options – Gas, electric, or both for maximum flexibility.
- Simple maintenance – Easy access for flushing and anode rod replacement.
- Widely available parts – Replacement components are easy to find.
Many long-term RVers praise the Suburban Advantage for lasting 8–10 years with proper care. The brand’s reputation for reliability means you’re less likely to face unexpected breakdowns on the road.
Cons: Where Does It Fall Short?
No product is perfect. Here are some downsides to consider:
- Heavy for its size – The steel tank is more durable, but also heavier than some aluminum or tankless models.
- Limited hot water supply – 6 gallons goes fast, especially with longer showers or multiple users.
- Manual ignition on some models – Lighting a pilot can be tricky, especially in cold or windy conditions.
- Not “endless” hot water – Once the tank is empty, there’s a wait for the next round of hot water.
- Noisy operation – Some users notice a “whooshing” sound during heating.
A common beginner mistake is expecting a tank water heater to perform like a home unit. In reality, RV heaters are smaller, and learning to “shower smart” (turning water off while soaping up) can help stretch your hot water supply.
How Does It Compare To Tankless Rv Water Heaters?
Tankless (on-demand) water heaters are gaining popularity. They promise endless hot water as long as you have fuel and water supply. How does the Suburban Advantage stack up?
| Feature | Suburban Advantage (Tank) | Tankless RV Heater |
|---|---|---|
| Hot Water Supply | 6–10 gallons at a time | Continuous (theoretically unlimited) |
| Recovery Time | 10–15 min (gas) | Instant |
| Installation | Fits standard cutouts | May require modifications |
| Energy Use | Efficient, but some standby loss | Only heats when needed |
| Cost | Lower ($400–$700) | Higher ($600–$1200+) |
| Winterizing | Drain tank | Drain unit, more steps |
| Maintenance | Simple, replace anode rod | Can be complex |
For most RVers, the Suburban Advantage’s value comes from simplicity and reliability. If you don’t need endless hot water and want an easy-to-maintain unit, a tank model is often the smarter choice.
Who Should Buy The Suburban Advantage Rv Tank Water Heater?
The Suburban Advantage is best for:
- Families or couples who want reliable hot water for showers and dishes
- Full-time RVers who value durability and easy repairs
- Campers who visit colder climates (porcelain tanks handle winterizing better)
- Owners who want a drop-in replacement for an older Suburban or Atwood heater
It may not be the best fit if you:
- Regularly camp with large groups needing lots of back-to-back hot showers
- Have a small, ultra-light trailer where every pound counts
- Want the latest “smart” features, like remote control or automatic temperature adjustment
Price And Value For Money
Prices for Suburban Advantage water heaters range from $400 to $700, depending on size and features. Professional installation can add $150–$300. Compared to tankless models, which often exceed $1000 installed, the Suburban is more budget-friendly.
But value isn’t just about price. Suburban’s long lifespan and affordable parts mean fewer surprise expenses over time. For example, a new anode rod costs under $20 and can prevent tank failure—a small price for peace of mind.
A detail many overlook: even if you switch to a tankless heater, you may need to upgrade your RV’s propane line or electrical system, which can double your costs.
Common Mistakes To Avoid
- Ignoring the anode rod – Not replacing this part can destroy your tank with rust.
- Not draining before winter – Frozen tanks crack and are not covered under warranty.
- Expecting long, home-style showers – RV water heaters need efficient water use.
- Choosing the wrong size – A 6-gallon tank is fine for 1–2 people, but families may need 10 gallons.
Real-world User Experiences
Many RVers report positive experiences after switching to the Suburban Advantage. For example, a couple traveling full-time in a 32’ fifth wheel said their 6-gallon model provided enough hot water for two showers and dishwashing every day, with only minor adjustments to their routine.
Another RVer noted that after five years, their heater still worked perfectly thanks to regular anode rod changes and flushing the tank twice a year. Problems tend to arise only when maintenance is skipped or if the water heater is not winterized properly.
Online forums and reviews often highlight the brand’s good customer support and easy-to-find replacement parts, giving extra confidence for long trips.
Is The Suburban Advantage Rv Tank Water Heater Worth It?
For most RV owners, the answer is yes—if you want reliability, easy maintenance, and proven performance. The Suburban Advantage isn’t flashy or “smart,” but it just works. If you’re upgrading from an older or failing unit, the drop-in fit saves time and money. And with proper care, you can expect years of trouble-free service.
However, if you want endless hot water for long showers or have a large family, a tankless model might suit you better—if you’re willing to pay more and possibly deal with more maintenance.
Before buying, think carefully about your camping style, group size, and how much maintenance you’re comfortable with. If you value simplicity and proven technology, the Suburban Advantage is a solid investment.
