Choosing RV Hot Water Heaters


An RV water heater is a must-have item for every motorhome. It can provide hot water for showers or other reasons So, make sure you get the right one.

There are several types of RV water heaters, including those that run off LP gas or electricity as well as those that run on electricity only as well as those that employ tanks to provide hot water on demand. The best RV water heater depends on many factors, including your budget and your needs.

Whatever type you choose, it’s crucial to know how to manage your water heater. You can learn the basics of using your water heater by reading a book or searching online.


Most tankless water heater can heat up to six or 10 gallon. There are smaller 4-gallon models and larger models of 16-gallon in case you’re looking to store lots of water. Consider how many guests you’ll be camping with and how much hot-water they’ll require when deciding on the size of your RV heater.

Then, you need to determine the degree to which your RV’s hot groundwater is. Then calculate how much heat is required to get it to the desired temperature. For instance that you would like a shower temperature of 110 F but live in south Florida with groundwater temperatures of 72 F and you need a 38 F temperature rise. You’ll need to consider an option that is tankless if the unit you are considering isn’t capable of handling that.

On-demand and instantaneous

Tankless RV water heaters heat water only when you need it, which makes them more efficient than traditional models. They’re also more adaptable and can be used with gas and electricity, so they can be a good choice for travelers who want to save money while conserving propane while boondocking.

Some tankless units have an inbuilt recirculation pump that pushes cold water through the heater, and then heats it up. This can reduce the time it takes for hot water to reach the sink, and can be controlled by the use of a timer, motion sensor, or even a smart speaker.

You can also choose a unit with digital connectivity, so that you can adjust the temperature and track hot-water and gas usage via your smartphone. This allows you to track your energy consumption while traveling.
