Choosing the Right Size RV Tankless Water Heater

When selecting an RV tankless water heater, it is crucial to choose the right size and capacity that best suits your needs. Estimating your water consumption and determining the flow rate and BTU rating required will help ensure optimal performance and efficiency. Additionally, the size of the unit should be compatible with the available space in your RV.

One way to determine the proper size is by considering the number of fixtures in your RV that require hot water. For example, if you have a small RV with only a kitchen sink and a bathroom, a unit with a lower flow rate and capacity may be sufficient. However, if you have a larger RV with multiple bathrooms and showers, a higher flow rate and capacity will be necessary to meet your hot water demands.
