What to Look for in an RV Water Heater
You’ll want to consider a few things before you make your RV water heater purchase. These features will help you make the best decision for your travel needs. For example, a solo traveler doesn’t need as big of a water heater as a family of six. A small travel trailer won’t have the room for an upgrade in size. So brush up on your RV water heater knowledge before deciding.
Most RV water heaters run on propane or electricity. Some diesel motorhomes use a diesel boiler, however.
Propane sources are a good choice for most because there are usually other appliances that use propane as well. Electricity is usually an optional add-on to propane heaters and can be used in conjunction with or instead of propane when you are plugged in.
Diesel boilers like Oasis or Aqua-Hot systems operate a boiler similar to how home boilers work. These get their fuel source from the coach’s fuel tank. This can be convenient because the coach may only have one fuel source instead of multiple.
The tank’s capacity determines how much hot water you’ll have at one time. Some smaller tanks only provide about 6 gallons of hot water, which means quick, five-minute military showers. But larger 12 or 16-gallon tanks will provide enough hot water for one person to take a longer shower.
If you want to conserve water, the tank size probably won’t matter much. But if you have a family with children and don’t want to use public bathhouses, you’ll want to get the largest size possible that fits in your RV.
Ease of Install:
When you need to replace a water heater, pay attention to if you can install it easily. Does it require a lot of tools? If so, do you have access to them? If it will take two people, do you have someone else who can help?
The weight may make a difference in the ease of installation, too. So do your research to know how much time it will take to replace your water heater and how easy or difficult the process will be.
Tank or Tankless:
Although a tankless water heater works well because it provides a never-ending hot water supply, it also costs more than a tank. If you have a tight budget, you’ll need to look at good tank options — some of which we list below.
But if you can afford a couple of hundred dollars more for your upgraded RV water heater, a tankless unit will heat up on demand rather than warming a full tank of water. You get hot water much faster because you don’t have to wait several minutes for the tank to get hot.

Finally, consider the amount of energy the new water heater will use. Some are more energy-efficient than others.
Usually, the larger the tank means the more energy it requires to heat it, whether with propane or electricity. This is also why you may like a tankless option better; they’re more efficient.
Some people try and save energy by turning he heater off when not in use, but this means you need to wait for it to heat before taking a shower.

The 7 Best RV Water Heaters That Are Worth the Upgrade
These RV water heaters vary in size, price, and energy source. They also differ from one tank, tankless, and portable options to meet the needs of different RVers. From this list, you can determine which RV water heater is worth the upgrade for your travel needs.
#1. Truma Aquago On Demand Water Heater
You can find two top-quality Truma AquaGo tankless water heaters — This heater utilizes technology that combines the tank and tankless designes to regulate the temperature well, which means no scalding when you take a shower.
