1. 8 Gallon Electric Tank Water Heater for RV, Camper, Kitchen & Food Truck – 120V 1500W Instant Hot Water, Wall or Floor Mounted
This 8-gallon electric tank water heater is a powerhouse for RVs, campers, and even food trucks. It runs on 120V and 1500W, providing instant hot water on demand. The tank design means you have a reservoir of hot water ready, so you don’t have to wait long for a shower or dishwashing. It’s versatile too—you can mount it on the wall or floor, making installation flexible for different RV layouts. Built with durability in mind, it’s CE, ROHS, and FCC certified, and features a thick stainless steel tank that resists corrosion. Safety is covered with leakage protection, high-temperature limiting, and auto temperature control.
Key Features That Stand Out
- ✓ 8-gallon capacity provides ample hot water for multiple uses
- ✓ 1500W/120V operation works with standard RV electrical systems
- ✓ Instant heating with rapid reheat technology minimizes wait time
- ✓ Durable stainless steel tank (1.88mm thick) for long-lasting performance
- ✓ Multiple safety protections including leakage protection and thermal cut-off
Why We Recommend It
We love this unit because it delivers reliable, on-demand hot water without the need for propane. It’s perfect for RVers who want to save on gas or have an electric-only setup. The large tank means you can take a decent shower without running out, and the safety certifications give peace of mind. It’s also surprisingly compact for its capacity, making it a great fit for space-constrained RVs.

2. Camco Hot Water Hybrid Heat Kit – Converts 6-Gallon RV LP Gas Water Heater to 120V Electric, Saves Propane (Model 11673)
If you already have a gas RV water heater and want to add electric capability without replacing the whole unit, the Camco Hybrid Heat Kit is the perfect solution. This clever kit converts your existing 6-gallon LP gas water heater to also run on 120V electricity. It includes an electric heating element that installs through the drain plug, a power switch with mounting bracket, and a fully adjustable thermostat. All necessary cords and color-coded wiring are included, making the DIY conversion straightforward. It’s a fantastic way to save propane and have the flexibility of both fuel sources.
Key Features That Stand Out
- ✓ Converts existing gas heater to electric without full replacement
- ✓ Adjustable thermostat for precise temperature control

- ✓ Works with most 6-gallon RV gas heaters (Atwood, Suburban, etc.)
Why We Recommend It
We recommend this kit because it’s incredibly cost-effective and practical. Instead of buying a whole new water heater, you can upgrade your existing one for a fraction of the price. It gives you the best of both worlds: gas for off-grid and electric when plugged in. The installation is relatively simple, and the ability to switch between fuels adds great flexibility for different camping situations.

Customer Reviews
Customer Review: Over the past couple years, I’ve spent hundreds of dollars on LPG. I have also been tired of switching my Atwood LPG water heater on and off to save money, and the unit not working when it’s raining. So, I decided to look into electric elements for RV gas heaters. The one here seemed to be the be
Customer Review: Very happy with this conversion kit. It keeps the LP burner and thermostat in place and adds an electric heater element through the drain plug opening.

Complete Buying Guide for RV Hot Water Heaters
Essential Factors We Consider
Choosing the right RV hot water heater involves several key factors. First, determine the fuel type: electric, propane, or hybrid. Electric heaters are quiet and efficient when you have shore power, but they draw a lot of amps. Propane heaters work off-grid but require ventilation and produce exhaust. Hybrid kits, like the Camco we reviewed, offer both. Next, consider capacity (gallons). A 6-gallon tank is common, but larger families may prefer 8-10 gallons. Recovery time is crucial—how quickly the heater can reheat water after use. Also, look at installation requirements: size, weight, and whether it fits your RV’s existing space. Finally, safety features like thermal cut-offs, pressure relief valves, and certifications (UL, CSA) are non-negotiable for peace of mind.
Budget Planning
RV hot water heaters range from $100 for basic models to over $500 for high-capacity or tankless units. Set a budget based on your needs. A conversion kit like the Camco is budget-friendly ($50-$100) if you already have a gas heater. A new electric tank heater typically costs $200-$400. Tankless heaters are pricier ($300-$800) but offer endless hot water. Remember to factor in installation costs if you’re not DIYing. Also, consider long-term savings: propane heaters cost more to operate, while electric may increase your campground electric bill but save propane. For boondockers, propane is often necessary unless you have a generator.
Final Thoughts
Your RV’s hot water needs depend heavily on your travel style. If you mostly stay at campgrounds with full hookups, an electric tank heater like our top pick is efficient and quiet. If you boondock frequently, a propane or hybrid system is essential. The Camco hybrid kit is a brilliant middle ground, letting you use electric when possible and propane when not. Always measure your existing space and check your RV’s electrical capacity before buying. And don’t forget maintenance—flushing the tank annually and checking anode rods (if you have a tank) will extend the life of your heater.

Frequently Asked Questions
Q: Can I install an RV hot water heater myself?
A: Yes, many RVers install their own heaters, especially if it’s a direct replacement. However, if you’re switching fuel types or dealing with electrical/gas lines, it’s wise to consult a professional. Always follow the manufacturer’s instructions and local codes. For simple electric units, ensure your RV’s electrical system can handle the amperage. For propane, check for gas leaks after installation.
Q: How do I winterize my RV hot water heater?
A: Winterizing is critical to prevent freezing damage. First, turn off the heater and let it cool. Drain the tank completely by opening the drain valve and pressure relief valve. If you have an electric element, remove it to drain any remaining water. For propely heaters, also blow out the gas line with compressed air. Some RVers add non-toxic antifreeze to the tank, but draining is usually sufficient. Always refer to your heater’s manual.
Q: What’s the difference between tank and tankless RV water heaters?
A: Tank heaters store a limited amount of hot water (e.g., 6-10 gallons) and recover over time. They’re simpler, cheaper, and provide consistent pressure. Tankless heaters heat water on demand, offering endless hot water but with a slight delay and potentially lower flow rates. Tankless units are more expensive and may require larger electrical or propane setups. Your choice depends on your hot water usage patterns and budget.
Q: How often should I flush my RV water heater tank?
A: It’s recommended to flush your tank at least once a year, or more frequently if you use hard water. Flushing removes sediment buildup that can reduce efficiency and damage the tank. To flush, connect a garden hose to the drain valve, open the pressure relief valve, and let water flow until it runs clear. You can also use a descaling solution for heavy buildup.
Q: Can I use an RV water heater for my camper van or tiny home?
A: Absolutely! Many RV water heaters are perfect for camper vans, tiny homes, and even off-grid cabins. Just ensure you have the appropriate power source (120V electric or propane) and ventilation if using gas. The compact size of units like our 8-gallon pick makes them ideal for small spaces. Always check local building codes for non-RV installations.
Choosing the right hot water heater can transform your RV experience from basic to luxurious. Whether you opt for the powerful and self-contained 8-gallon electric tank or the versatile Camco hybrid conversion, you’re investing in comfort on the road.
