Having a water heater or a hot water tank in your RV comes in handy when you are out for biking and hiking or any other escapades with your family. Unfortunately, the average hot water tank meant for RVs can only hold between 6 to 10 gallons of water, thereby making it impossible for a family of five to enjoy nice warm showers after a beautiful day outdoors. However, thanks to the invention of tankless water heaters, no one has to care about hot water tanks anymore.
There are many reasons why the tankless water heater is better than typical hot water tanks but the most important feature is that it ensures a limitless amount of hot water is in your RV. As if that is not enough, tankless water heaters only operate when hot water is flowing, thereby saving up to 50% of your average propane consumption.

What to look for in a Good RV Tankless Water Heater
So, what criterion does one use when buying a great RV tankless water heater? To start with, there are three main types of water heaters: propane powered, electricity powered and battery cell powered water heaters. That said, the following are other factors and features that should help you settle on a great tankless heater for your RV.
Water Flow Rate
Flow rates refer to the amount of hot water delivered per every single minute. And since most people use RV water heaters for shower purposes, a water heater that can deliver 2-2.5 gallons per minute is enough for an average family.
High temperature
On average, a shower demands 104-1060 F temperatures while kitchen cleaning needs may ask for much less. That said, a great water heater is one that can deliver a temperature rise of between 40 and 60 degrees F. Propane powered tankless water heaters are better at offering temperature rise than their electricity powered counterparts.
The cost of the heater and its overall quality are other crucial factors that you should pay special attention to while purchasing a tankless water heater. Finally, look for the presence of a company warranty to ensure that you are protected should some of its parts get faulty too soon.
Conclusion
The time for purchasing hot water storage tanks for RVs is long gone and people are now shifting their focus towards high quality best RV tankless water heaters in the market. These water heaters as you may have noted from the reviews above have more features and better efficiency than a standard tank inside your RV.
They save you on energy, help you enjoy more showers since they are not limited by a tank and help you regulate the temperature with which you shower as well. Some of these great water heaters are also very small to help save space in your RV. Their modern and meaningful features like automatic operation, timers and water resistance capabilities are just some of the other features that should prompt you to have one for yourself. After all, they are so affordable and vary very slightly in price with average hot water tanks.
We bought Eccotemp water heater for our RV, and it has been a dream! We fulltime in our RV, and use it on a daily basis. The only time we have issues is when the water pressure is too low, not a fault of the heater. We read reviews that complained about the freezing issue, we mounted the unit on an inside wall perpendicular to the outside wall to where it was vented. This kept the coils away from the colder outside wall, and yes it got cold this winter, and we never had one issue with freezing.
