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 higher-output water heater to meet greater hot water demand. Similarly, if you have a smaller RV and only need hot water for one or two people, a lower-capacity model around 48,000-55,000 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 a more realistic idea of what size RV tankless water heater you may need, focus on hot water demand, flow rate, and temperature rise rather than RV length alone:

• For smaller RVs, weekend trips, or one to two people, a tankless water heater around 2.5-2.9 GPM is usually a practical choice for shower and sink use.
• For mid-size RVs, couples, or small families who use hot water more often, a 2.9-3.6 GPM model can provide stronger flow and better comfort for daily routines.
• For larger rigs, families, full-time RV living, or more demanding hot water needs, a 3.6-3.9 GPM model with higher BTU output can help support back-to-back showers, kitchen cleanup, and longer stays.

Keep in mind that these are general guidelines. Actual performance depends on inlet water temperature, water pressure, propane supply, desired outlet temperature, and how many fixtures are used at the same time.

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.
