Understanding Electric Tankless Water Heaters
Electric tankless water heaters heat water directly without the use of a storage tank. When a hot water tap is turned on, cold water travels through a pipe into the unit, where it is heated by electric coils. This ensures you have a continuous supply of hot water, making it ideal for RVs, where space and energy efficiency are paramount.
Benefits of Electric Tankless Water Heaters for RVs
-
Unlimited Hot Water: Unlike traditional water heaters, tankless models provide a steady flow of hot water, making showers and dishwashing hassle-free.
-
Space Efficiency: These units are compact, saving valuable storage space in your RV. This is particularly advantageous for smaller units or campers where every inch counts.
-
Energy Efficiency: Electric tankless water heaters only operate when hot water is needed, which can lead to significant energy savings over time compared to traditional systems.
-
Longevity: With proper maintenance, tankless water heaters can last longer than tank-style heaters, offering a better return on investment.
Key Features to Consider
When selecting an electric tankless water heater for your RV, consider the following features:
Flow Rate
The flow rate, typically measured in gallons per minute (GPM), indicates how much hot water the heater can produce at once. For RVs, a flow rate of 2-5 GPM is generally sufficient for typical usage.
Temperature Rise
This refers to how much the unit can heat water to meet your desired temperature. Assess the incoming water temperature and the maximum temperature you need for a comfortable experience.
Energy Efficiency Ratings
Look for models with high energy efficiency ratings to minimize power consumption while providing ample hot water.
Size and Weight
Ensure the heater’s size and weight fit well within your RV’s layout and weight limits.
