Understanding RV Tankless Water Heaters
Tankless water heaters work by heating water on demand rather than maintaining a reservoir of hot water. This technology means you can enjoy a hot shower or wash dishes without the worry of running out of hot water. The system is activated when you turn on the hot water tap, igniting the propane and heating the water instantly.

How to Choose the Right RV Propane Tankless Water Heater
Choosing the right propane tankless water heater for your RV involves several key factors:
1. Flow Rate
The flow rate, measured in gallons per minute (GPM), determines how much hot water can be supplied at once. Consider your RV’s needs based on the number of occupants and typical usage. Models with a flow rate of 2-4 GPM are suitable for most RVs.
2. Energy Efficiency
Look for models with high energy efficiency ratings. This will ensure you save on fuel costs over time. Many modern units have an Energy Factor (EF) rating that can help you compare efficiency.
3. Size and Weight
Ensure the unit you choose fits within your RV’s available space and doesn’t add excessive weight. Many tankless units are designed to be compact and lightweight.
4. Installation Requirements
Check if the unit requires professional installation or if it can be a DIY project. Some models can be installed easily, while others may need additional modifications.
5. Brand Reputation and Reviews
Research brands and read reviews from sites like www.jeffsetter.com, rvproperly.com, and thecampingnerd.com to gauge reliability and performance. Look for models that have received positive feedback from users.
