A Little Background

Water is the most precious element in the world even from the beginning of time. Without water, all of us would starve and die. Without water, there would be no life left on Earth. This is what makes our planet unique from the rest of the planets in the solar system (except Neptune, some of the other moons and more recently Mars) because we have a balanced ecosystem that is in the habitable zone to make life flourish unlike in other planets. We should consider water on earth as a gift from the heavens or whoever designed our universe. But the main problem is that not everyone thinks that way and disregards water conservation.
Conserving water is something that most people forget to look on and practice. Imagine if you left the shower or faucet open – imagine how many people in super remote areas could drink from that, since they have no water sources and clean resources around. You should definitely do your part when it comes to conserving water and not let it go to waste. While all of us at home have convenience when it comes to plumbing system and water sources, some places out there will have limited water supply. One example is that if you camp out, you will definitely worry about getting water.

Living in an RV or camping out becomes very inconvenient if you have limited water source. If you go into the jungle, you can find swamps but with murky water. Rivers are okay but you need some filtration to make it clean, especially if you happened to stumble upon a dead river where people have been throwing trash and contaminating it and thus, clearing it of river fish and life. Water resources when you are living in an RV or camper can be drastic if you don’t know where to look for, and this is why people are very conservative with water when camping.
However, with that said, camping out or living in an RV practices our skills when it comes to conserving water. We are only limited to river water or ocean water or such – unless we have a big tank storage. On the other hand, this will not guarantee that you can live in your mobile home forever. You may use it for extended periods of time but if you plan to make it a permanent home, that’s another question. You might want to double your efforts when it comes to water storage and filtration, but that’s another story altogether.

Not every time do we have to live in an RV or camp out under a sunny or summer weather, as the weather might change from sunny to stormy or chilly winter. Imagine taking a shower in the winter – you can’t because it’s freezing. You might think it’s sunny at first but when the temperature suddenly changes and all you have is cold water, you will probably scream. That’s the problem with most homes and with most campers. You never know what could happen so you must be prepared.

Our homes have water heaters, don’t they? This is exactly why water heaters have been invented, especially for use in super winter places. While tropical countries and super desert countries don’t really need a water heater, most homes in the northern areas definitely do – especially those with greatly cold winters in which they cannot take a shower properly or take a bath properly. Anywhere where there is a cold climate, you will definitely need a water heater to supply your bathing needs or other specific water heating needs.

Water heaters are one of the most convenient inventions in the world. Without them, we could not survive the winter and keep ourselves clean. Without them, we would probably be drinking cold coffee or cold milk all the time. We would not have such conveniences in the cold winter atmosphere without a useful and effective water heater. It is an essential part of any home that is situated in a place where cold weather is more likely to occur than sunny weather.

Without water heaters, we would shiver in the winter and stink due to not taking a shower. This is exactly the reason why people install a water heating system for their homes. They must ensure that the heating system actually works and that it will definitely keep your bath time super warm and protect you from getting sick from the cold water from the shower.

Contrary to popular belief, water heaters can also be present in RVs, campers, trailers and mobile homes. As a matter of fact, because RVs are much like our homes, they can be installed with a water heater to protect us from the cold. Since RVs are designed to be weather proof, they should also keep us convenient in taking showers even in the winter time. RVs aren’t always used in the summer – sometimes you may have to use them during the winter as well and this is why you should get an RV water heater for your mobile home.

In fact, even cabins and small homes can make the use of a small, convenient and portable water heater. Anything that is small and portable as a water heater will definitely work in any small space area for a multitude of purposes. In fact, water heaters are not just for taking baths – they are also used in a variety of purposes, you name them. Some may even use them for businesses.

The amount of heated water you can have on an RV water heater is not like the one you can use at home. Obviously, since water heaters for RVs only give you limited water, you have to conserve. You cannot take full-on showers and expend a lot of water so you have to keep in mind that most RV water heaters only have limited tanks with gallons.

This is however, altered when it comes to having a tankless or on-demand RV water heater system. This system is much more expensive than RV water heaters that are tank-based. If you are not content with 6 gallons or 10 gallons of capacity for the water heater you have on your RV, maybe it is time to switch to a tankless system. Take note that a tankless system is very expensive but if it will give you a peace of mind and convenience then it is a worth-it system to invest on for your RV.

Heating up water helps to kill germs and bacteria during bath time. Most studies say that hot water helps to revitalize your skin and free you from bacteria and viruses, that otherwise may live and dwell on cold water. However, most dermatologists agree that the water you should heat up should not be too hot or else it may dry up your skin, especially during the winter. In addition to that, to conserve water, you should also limit your showers, especially in the RV, so you can have more uses from it.

An RV water heater is an effective and essential part of your RV in case you want to use it for the winter. Generally speaking, RVs aren’t just for summer adventures but sometimes also for cold, winter nights. If you get stuck on a snowy road or rain storm and you have nowhere to go, it is very convenient to take a warm shower using an RV water heater inside your RV, right?

How We Picked

When it comes to choosing the best RV water heater, we considered the following:
The BTU or British thermal unit defines how strong and effective a water heater is for your RV. Always know the BTU of your RV water heater. However, do know that the higher the BTU, the higher the price.
The RV water heater may be in any of the following formats: gas (LP or propane), electric ignition or tankless on-demand RV water heater. Gas or LP ignition is the most convenient and may come in manual or automatic ignition depending on the price and model you buy. Electric ignition is a little step ahead but you will be less worried about the dangers of gas leaks and such. The tankless or on-demand system is the most expensive of all since it gives you unlimited hot water supply.
Consider the amount of gallons and capacity if the RV water heater is not tankless. The most common capacities of a lot of RV water heaters out there range from 6 gallons to 10 gallons depending on what you need. Of course, the higher the capacity, the bigger price you need to watch for.
Know if the RV water heater is okay for use indoors only or also okay for outdoors. Generally, most RV water heaters will be only used for indoor with a little bit of ventilation especially for gas ignition ones, but do know if there are brands that can be used outdoors.
Know the type of ignition the RV water heater uses. They can come in pilot ignition, automatic ignition, electronic ignition and many others, depending on the type of water heater for your RV and the source of its heating and fuel.
The price must be considered but it is not a decisive factor. Generally, the tankless or on-demand systems will be the most expensive of all.
The warranty of the RV water heater is important, as it is an electric item that may run into some manufacturing defects. Since you cannot have a live testing when you buy online, make sure there are good return and exchange policies before you buy.

Other Frequently Asked Questions

Q: What is the importance of maintaining your water heater?
A: According to Len The Plumber, it gives you more savings for your money and gives you a more efficient system and you can get hot water faster than before so you can save on electricity. Additionally, it is good that you flush your water heater every 6 months or so and you will not be surprised with sudden cold showers when your water heater stops working. Moreover, the costly repairs will be reduced if you properly maintain your water heater by doing a plumbing inspection with a certified plumbing expert.

Q: What are some of the things you need to know about your RV water heater?
A: According to RV Share , you can choose between electricity, propane or heat when it comes to heating your RV water. Electric heating is the most convenient as there will be no pilot light to worry about while using engine heat is the most economical but it might take its toll on your engine instead and is only usable when your engine is running.
All RV water tanks have a variation when it comes down to size and the most common RV water tanks are 6 gallon or 10 gallons depending on your needs. Suburban and Atwood are among the most common water heater manufacturers specifically for RVs and mobile homes and since they are for mobile use, RV water heaters are typically smaller so you have to conserve some more. However, manufacturers like Girard sell tankless water heaters which are a bit pricier but you will never run out of steaming water. Furthermore, an anode rod can help to prevent hard water corrosion that might occur inside your tank.

Q: Any tips on choosing a great water heater for your RV?
A: According to the guide by Camping World , the most common ones are the gas water heater that works on LP gas in which you have to manually light up the water heater. These are the most common and inexpensive RV water heaters. Also, if you want a hassle-free water heater you can go for something that has a direct spark or DSI which has an automatic ignition rather than manual but also uses LP as the gas supply.
You can also have a more convenient electric water heater that also has DSI or gas options which heat up nicely but a bit pricier than the first two. On-demand or tankless water heaters are the most expensive ones and run at higher BTUs than the previous ones.
