What to Look for Before Buying the Best Electric Water Heater For Rv
Choosing the right electric water heater for your RV involves more than just picking one off a list. Your travel style, RV size, and electrical system all play a crucial role. Here’s a breakdown of what to consider to ensure you get the perfect fit for your adventures.
Find Your Need - Compatibility and use case considerations
First, think about how you’ll use hot water. Are you a solo traveler who just needs hot water for washing dishes, or a family that needs to support multiple quick showers?
- Tank vs. Tankless: Tank heaters (like the Suburban or Bosch) store a set amount of hot water (e.g., 4-6 gallons). They are great for providing a strong, consistent flow for a short period, making them suitable for showers. Tankless heaters (like the DOYXC or ECOTINYMACH models) heat water as it passes through, providing an endless supply. However, their flow rate (Gallons Per Minute, or GPM) can be limited, making them better suited for sinks.
- Point-of-Use vs. Whole-RV: Most compact electric heaters are ‘point-of-use’, meaning they are installed near a single fixture (like a sink) to provide instant hot water. Larger tank models are designed to supply the entire RV. Decide if you need a dedicated heater for one spot or a central unit.
Budget - Setting realistic price expectations
Electric water heaters for RVs can vary significantly in price. Setting a budget helps narrow your options.
- Budget-Friendly ($70 - $150): In this range, you’ll find basic 110V tankless point-of-use heaters and conversion kits like the Briidea. These are great for simple upgrades or single-sink applications.
- Mid-Range ($150 - $300): This category includes high-quality mini-tanks from reputable brands like Bosch and more powerful tankless models with better features. The Feelrogast 8-gallon tank also falls here.
- Premium ($300+): Here you’ll find robust, dual-fuel tank heaters like the Suburban SW6DE, which are built for maximum durability and flexibility. These are long-term investments for serious RVers.
Key Features - Most important technical specifications
Look closely at the numbers to ensure a heater meets your needs.
- Power (Watts) and Amperage (Amps): This is critical. A 3000W heater on a 110V system will draw around 27 amps. Ensure your RV’s circuit breaker and wiring can handle this load. A 5500W unit will require an even more robust system. Always check the manufacturer’s requirements.
- Recovery Rate (for Tank Heaters): This measures how many gallons of water the unit can heat in an hour. A higher recovery rate means less waiting time between showers. The Suburban model excels here with its dual-fuel options.
- Flow Rate (for Tankless Heaters): Measured in GPM, this tells you how much hot water the unit can produce at once. A lower flow rate is fine for a sink, but you’ll need a higher GPM for a satisfying shower.
- Temperature Rise: Tankless heaters are rated by the temperature rise they can achieve at a certain flow rate. For example, a unit might raise the water temperature by 45°F at 0.5 GPM. If your incoming water is very cold, the final temperature will be lower.
Quality & Durability - What to look for in construction
An RV is a high-vibration environment, so your water heater needs to be tough.
- Tank Material: For tank heaters, look for porcelain-lined steel, which is the gold standard for corrosion resistance.
- Heating Element: Stainless steel heating elements (especially 316L grade) are durable and resist corrosion, which is particularly important if you encounter hard water on your travels.
- Anode Rod: A replaceable anode rod in a steel tank is a non-negotiable feature for longevity. It sacrificially corrodes to protect the tank itself.
Brand Reputation - Importance of established manufacturers
While generic brands can offer value, established manufacturers like Suburban and Bosch have a long track record of reliability, better warranty support, and readily available replacement parts. For a critical component like a water heater, investing in a trusted brand often pays off in the long run.
Portability/Size - Considerations for space and storage
Space is always at a premium in an RV. Before you buy, grab a tape measure.
- Dimensions: Carefully measure the cabinet or compartment where you plan to install the heater. Check the product dimensions (height, width, and depth) to ensure a proper fit.
- Weight: Consider the weight of the unit, especially when filled with water. A 6-gallon heater will add about 50 pounds of weight (6 gallons x ~8.34 lbs/gallon) plus the weight of the unit itself. Ensure the mounting location can support it.
Is it A Wise Decision to Buy electric water heater for rv?
Absolutely. Investing in an electric water heater for your RV is one of the wisest upgrades you can make for enhancing comfort and convenience on the road. While many RVs come with propane-only heaters, adding an electric option provides invaluable flexibility and can lead to significant long-term savings. When you’re staying at a campground with electrical hookups, you’re already paying for the electricity. Using it to heat your water saves your limited supply of propane for when you’re boondocking or on the move.
Compared to the alternative of relying solely on propane, an electric heater offers a silent, odorless, and often safer operation inside your living space. Models like the point-of-use tankless heaters provide the added benefit of instant hot water, eliminating the water waste that occurs while you wait for heated water to travel from a central tank. Furthermore, having a dual-fuel system with both electric and gas options, like in the Suburban SW6DE, provides redundancy. If one system fails or you run out of propane, you have a reliable backup, ensuring you’re never left in the cold. It’s a relatively small investment that dramatically improves your quality of life on the road.
What Is the Best Way to Choose electric water heater for rv?
Choosing the best electric water heater for your RV is a systematic process. By following these steps, you can avoid common pitfalls and select a unit that perfectly matches your needs.
Assess Your Hot Water Demand: Start by analyzing your usage. How many people will be using hot water? Will it be primarily for washing hands and dishes, or do you need it for daily showers? This will be the single biggest factor in deciding between a small point-of-use tankless model and a larger 6-gallon tank heater.
Inspect Your RV’s Electrical System: This step is crucial. Identify the circuit breaker for your current water heater or the spare circuit you plan to use. Check its amperage rating (e.g., 15A, 20A, 30A). Compare this with the requirements of the heaters you’re considering. Many powerful tankless models require 30A or more, which might necessitate an electrical system upgrade. If you’re unsure, consult a certified RV technician.
Measure Your Installation Space: Get precise measurements of the compartment where the heater will go. Account for not just the unit itself, but also the space needed for water lines and electrical connections. Remember that some tankless units have specific mounting requirements, such as vertical-only installation.
Compare Key Models: Once you know your requirements (capacity, power, size), compare 2-3 models that fit your criteria. Look at factors like recovery rate, energy efficiency, warranty, and brand reputation. Reading user reviews from other RV owners can provide invaluable real-world insights.
Avoid Common Mistakes: A frequent error is buying a heater that is too powerful for the RV’s electrical system, leading to constantly tripped breakers. Another is choosing a tankless model for showering without understanding its flow rate limitations. Also, don’t forget to consider a unit’s maintenance needs, like the periodic replacement of an anode rod in a tank heater.
By investing a little time in research and planning, you can confidently choose an electric water heater that will provide reliable service for many adventures to come.

How much should I spend on electric water heater for rv?
You can expect to spend between $70 for a basic conversion kit to over $300 for a high-quality, dual-fuel tank model. A good budget for a reliable and efficient unit, whether a quality mini-tank or a capable tankless heater, is typically in the $150 to $250 range. This price point offers a great balance of features, durability, and performance.
What features are most important in electric water heater for rv?
The most important features are compatibility with your RV’s electrical system (voltage and amperage), appropriate size/capacity for your needs, and durability. For tank heaters, a porcelain-lined tank and an anode rod are crucial. For tankless heaters, look for adequate power (watts) for your desired temperature rise and robust safety features like automatic shutoffs.
How do I maintain my electric water heater for rv?
Maintenance is key to longevity. For tank heaters, you should drain the tank and flush out sediment at least once a year. It’s also critical to inspect the anode rod annually and replace it if it’s significantly corroded. For all types, regularly check for leaks at the connections and ensure the electrical wiring remains secure.
Are expensive electric water heater for rv worth it?
Often, yes. More expensive models like the Suburban SW6DE typically offer superior build quality, better insulation, dual-fuel capability, and longer warranties. These features translate to better reliability, more flexibility, and a longer lifespan. While a budget model can work for light use, a premium heater is a worthwhile investment for frequent or full-time RVers.
What brands make the best electric water heater for rv?
Suburban is an industry leader for traditional RV tank water heaters, known for their durability and reliability. For point-of-use and mini-tank electric heaters, Bosch is a highly respected brand known for quality engineering. Brands like DOYXC and Feelrogast are also gaining popularity for their feature-rich and versatile electric models.
How long do electric water heater for rv typically last?
With proper maintenance, a good quality RV water heater can last anywhere from 8 to 12 years. The lifespan of a tank heater is heavily dependent on regular anode rod replacement and flushing. Tankless models can sometimes last longer as they are less prone to corrosion, but their electronic components can be a point of failure over time.
Can I find good electric water heater for rv on a budget?
Yes, you can. Models like the xwdzswgs or Generic 3000W tankless heaters offer instant hot water for a single sink at a very low price. Additionally, the Briidea conversion kit is an extremely budget-friendly way to add electric capability to your existing gas heater. These options provide excellent functionality without a large financial commitment.
What’s the difference between a tank and tankless water heater for an RV?
A tank heater stores and continuously heats a set volume of water (e.g., 6 gallons), providing strong pressure until the tank is depleted, after which it needs time to recover. A tankless heater heats water on demand as it flows through the unit, offering an endless supply of hot water but often at a lower flow rate.
What are the electrical requirements for an RV electric water heater?
The requirements vary widely. A mini-tank like the Bosch may plug into a standard 15A outlet. A large tank heater element typically requires a 15-20A circuit. A 3000W tankless model usually needs a dedicated 30-32A breaker, while a powerful 5500W unit can require up to a 60A breaker and heavy-gauge wiring, which is uncommon in most standard RVs. Always verify your RV’s capabilities.
