How to Choose an RV Water Heater

With many available options, selecting the right RV water heater can be overwhelming. Here are the key factors to consider when making your decision:

1. Type: RV water heaters come in two main types – tank and tankless. Tank models store and heat a fixed amount of water, while tankless heaters provide hot water on demand. Consider your usage patterns and space constraints when choosing between the two.
2. Fuel Source: RV water heaters typically run on propane, electricity, or both. Propane heaters are more efficient and work well off-grid, while electric models are convenient when you have shore power. Dual-fuel options offer flexibility for various camping situations.
3. Capacity: For tank models, consider how much hot water you need. Common sizes range from 6 to 10 gallons. Larger families or those using more hot water may opt for a bigger tank or a tankless model.
4. Energy Efficiency: Look for models with high energy efficiency ratings to save on fuel costs and reduce your environmental impact. Tankless heaters are generally more efficient than tank models.
5. Installation and Compatibility: Ensure your chosen water heater is compatible with your RV’s existing setup. Consider the dimensions, venting requirements, and ease of installation.
6. Recovery Rate: This refers to how quickly the heater can warm up a new tank of water. A higher recovery rate means less waiting time between showers.
7. Additional Features: Some models offer features like freeze protection, adjustable temperature controls, or smartphone connectivity. Determine which features are essential for your needs.
8. Budget: RV water heaters range in price from budget-friendly options to high-end models. Balance your needs with your budget to find the best value.

By considering these factors, you’ll be well-equipped to choose an RV water heater that meets your specific requirements and enhances your camping experience.

Pro Tip: Before purchasing, measure the space available in your RV for the water heater. This will help you narrow down your options and ensure a proper fit.

Frequently Asked Questions

How long do RV water heaters typically last?

RV water heaters generally last between 8 to 12 years with proper maintenance. Tank-style heaters may have a shorter lifespan compared to tankless models due to potential corrosion and sediment buildup. Regular maintenance, such as flushing the tank and replacing the anode rod (if applicable), can help extend the life of your water heater.

Can I use my RV water heater while driving?

In most cases, using your RV water heater while driving is not recommended. The movement of the vehicle can cause water to slosh around in the tank, potentially damaging the heating elements or causing uneven heating. Additionally, using propane appliances while in motion can be dangerous. However, some RVs have motor aid systems that can heat water using excess engine heat while driving.

How do I winterize my RV water heater?

To winterize your RV water heater:

1. Turn off the power and gas supply to the water heater.
2. Drain the tank completely using the drain plug.
3. Bypass the water heater using the bypass valves (if equipped).
4. Add RV antifreeze to your water system according to the manufacturer’s instructions.
5. For tankless models, follow the specific winterization guidelines provided by the manufacturer.

Always refer to your RV and water heater manuals for model-specific winterization instructions.

What’s the difference between a 6-gallon and a 10-gallon RV water heater?

The main difference is the amount of hot water available before the heater needs to recover. A 10-gallon heater provides more hot water at once, making it suitable for larger families or RVs with multiple bathrooms. However, 10-gallon models take up more space and may have a longer recovery time. A 6-gallon heater is more compact and energy-efficient but may require more frequent recovery periods during heavy use.
