Popular RV hot water heater models you can find on the market, online like Amazon and RV stores, are the ones using propane gas and electric as the fuel source. With the most common sizes of 6 and 10 gallons, these small and compact heating units can be installed in almost any recreational vehicle and motor home.
RV water heaters are built small, lightweight, with the intention to be installed outside, below the floor or behind the baggage door, so you can have more space to enjoy your mobile home, and still be able to service these heating appliances.
Not only that they are convenient to use but there are RV hot water heater models that are providing a great benefit of utilizing engine's heat for water heating (while driving) and electricity from electrical system or generator.
When looking to buy RV water heater, the best models are those that meet all your needs, have a decent tank life, high performance and are reliable. You don't want to go outdoors, for a camping in the mountains and discover that your unit is not working.
And if the poor weather and driving through the rough terrain away from civilization concerns you, don't worry, RV hot water heater units are protected against voltage spikes and shorts in the electrical system and feature protection for electronic ignition caused by excessive heat conditions.
Size is also important, and depends on how many of you are usually traveling and using hot water for shower or dishes, and what is the demand. You can buy models with a capacity from 3 gallons up to 16 gallons.
Note: If you are not using RV during the winter time, try to protect the heating / plumbing system, by either draining the system or adding the antifreeze. You should be careful there, remove the anode rod first as it might get affected by corrosive action.
