How to Choose the Right Size Tankless Water Heater for Your RV: A Comprehensive Guide

Are you planning a road trip with your RV and wondering what size tankless water heater you should get? Look no further!

When it comes to choosing the right size tankless water heater for your RV, there are a few factors to consider.

First, consider the size of your RV.

A larger RV will naturally need a larger water heater to meet the demand for hot water. Similarly, if you have a smaller RV and only need hot water for one or two people, a smaller water heater, around 42,000 BTU , may be sufficient. Next, think about your hot water needs. How many people will be using hot water in your RV at one time? Will you be using hot water for showers, washing dishes, or doing laundry? The more hot water you need, the larger the water heater you will need.

It's also important to consider the climate in which you'll be using your RV

If you'll be traveling to colder climates, you may need a larger water heater to ensure that you have enough hot water to meet your needs.
To give you an idea of ​​what size water heater you might need, here are some general guidelines:

 

  • For an RV that is under 25 feet long and has one or two occupants, a 6-9 gallon per minute (GPM) tankless water heater should be sufficient.
  • For an RV that is 25-40 feet long and has two to four occupants, a 9-12 GPM tankless water heater should work.
  • For an RV that is over 40 feet long and has four or more occupants, a 12-16 GPM tankless water heater may be necessary.

Keep in mind that these are just rough estimates and the actual size water heater you need may vary based on your specific hot water needs and the climate in which you'll be using your RV.

Overall, investing in a tankless water heater for your RV can be a great choice. Tankless water heaters provide an endless supply of hot water and take up less space than traditional tank-style water heaters. Plus, they're more energy efficient, as they only heat water as it's needed rather than constantly heating and maintaining a tank of hot water.

So, the next time you hit the road with your RV, make sure you have the right size tankless water heater to meet your hot water needs and ensure a comfortable trip for all.
