Choosing the right water heater for your RV can significantly impact your camping experience. Tankless water heaters, also known as on-demand water heaters, are increasingly popular among RV owners due to their space-saving design and potential for energy efficiency. This comprehensive guide will explore the advantages, disadvantages, and considerations when installing a tankless water heater in your RV.
What are the Benefits of a Tankless Water Heater in an RV?
Tankless water heaters offer several compelling advantages over traditional tank-style heaters:
- Space Saving: This is arguably the biggest draw for RV owners. Eliminating the bulky tank frees up valuable storage space.
- Endless Hot Water: Unlike tank heaters with limited capacity, tankless units provide hot water on demand as long as you have propane or electricity. Perfect for multiple showers or washing dishes.
- Increased Efficiency (Potentially): While initial cost is higher, tankless units can be more energy-efficient in the long run, as they only heat water when needed, eliminating standby heat loss associated with tank heaters. However, this depends on usage patterns and specific model efficiency.
- Longer Lifespan: Tankless heaters typically boast a longer lifespan than tank heaters, reducing the frequency of replacements.
What are the Drawbacks of Tankless Water Heaters in RVs?
Despite their advantages, tankless water heaters also present some drawbacks:
- Higher Initial Cost: The upfront investment is considerably higher compared to tank water heaters.
- Electrical Demand: Electric tankless units require a significant amount of amperage, which may necessitate upgrades to your RV's electrical system. Propane models require a sufficient propane supply.
- Water Pressure Dependence: Performance can be affected by low water pressure, resulting in a less powerful hot water flow.
- Complexity: Installation can be more complex than a tank heater, potentially requiring professional assistance.
How Much Hot Water Can an RV Tankless Water Heater Provide?
The amount of hot water a tankless heater provides depends on several factors, including:
- Unit Size (BTU/hr or kW): Higher BTU/hr (for propane) or kW (for electric) ratings deliver more hot water.
- Water Inlet Temperature: Colder water requires more energy to heat, resulting in a potentially slower flow of hot water.
- Water Pressure: Sufficient water pressure is crucial for optimal performance.
What is the Best Type of Tankless Water Heater for an RV?
The best type of tankless water heater for your RV depends on your specific needs and RV setup. Propane and electric models each have their pros and cons:
- Propane Tankless Water Heaters: Offer independence from shore power but require a sufficient propane supply and venting.
- Electric Tankless Water Heaters: Convenient if you have access to shore power but demand higher amperage.
How Much Does a Tankless Water Heater Cost for an RV?
Prices vary considerably depending on the brand, BTU/kW rating, features, and type (propane or electric). Expect to pay significantly more than for a comparable tank-style heater.
Are Tankless Water Heaters Worth It for RVs?
Whether a tankless water heater is worthwhile depends on your individual priorities. If space is at a premium and you value on-demand hot water, the higher initial cost might be justified. However, carefully weigh the pros and cons, and consider your budget, electrical system capacity, and propane supply before making a decision. For some RVers, the convenience and potential long-term energy savings outweigh the higher initial investment, while others find that a tank water heater suffices for their needs.
How Do I Install a Tankless Water Heater in My RV?
Installing a tankless water heater in an RV is a more complex process than installing a tank-style heater. It's generally recommended to seek professional installation, particularly if you lack plumbing and electrical experience. Improper installation can lead to safety hazards and void warranties.
This guide provides a solid foundation for understanding tankless water heaters for RVs. Remember to research specific models and consult with professionals to ensure the right choice for your needs and RV setup.
