When you make the decision to purchase an RV, you are making a serious financial commitment. Depending on the RV you decide to purchase, you could be making a purchase that reaches six figures in price. However, you are not done making purchases after you buy your RV. There are a few other things you will need to purchase to ensure that you have everything running well when you head out on your trip. One of those things is an RV water heater tank.
An RV water heater tank is an essential purchase for anyone that plans on using their RV for a significant amount of time. Without one all your water will be cold, so you will be limited in what you can do. You will not be able to take a hot shower, and you will not be able to properly wash your dishes.
So, you will need to take the time to find the best RV water heater tank for you. There are several options available to you, but not all will be a great fit. If you have a smaller RV, you might not need a large water heater tank. Alternatively, you may want to purchase a big water heater tank if you have a larger RV and plan on bringing more people on your next trip. The more people coming with you on your trip, the more hot water you will need.
All About RV Water Heater Tanks
When it comes to RV water heater tanks they are split up into sizes and ways to heat the water. The are two major sizes for water heater tanks, 6 and 10 gallons. There are also two main ways to heat the water in the tank, propane, and electric. Each as their pros and cons. So, you will need to consider which is the best option for you.
Electric and Propane
Electric water heater tanks are some of the most popular because they are also some of the easiest to maintain. Once they are up and running there is not really anything you need to do. You do not need to worry about the pilot light going out. All you need to do is switch the heat on and it should sustain itself.
Electric water heater tanks are usually cheaper than other options and are very efficient. Unfortunately, they do take longer to heat things up, and they tend to have higher operating costs. So, these are things you will need to balance when making your purchase.
One of the biggest benefits of using a propane water heater tank is that it will generally pay for itself over time. You do not need to pay nearly as much for fuel with the propane tank. You will need to replenish your propane every once in a while, but that should be relatively infrequent. They are also able to heat more hot water per hour than an electric heater.
Propane heaters will also work if you don’t have electricity or there are generator restrictions at your campground. Unfortunately, the base price of a propane water heater is higher than an electric one. So, if you can’t afford to pay a little extra upfront you will need to go with an electric option. You also need to maintain your propane heater to find any gas leaks.
The two most common sizes for RV water heater tanks are 6 and 10 gallons. You can find smaller and larger options, but 6 and 10 gallons is usually a good size for most people. The more people you plan on having in your RV, the larger the water heater tank you will need. It is better to get a slightly bigger tank than you expect you will need, because otherwise there is a risk that you deplete your supply.
Which RV Water Heater Is Best for Me?
When you are trying to figure out which RV water heater is best for you, you need to ask yourself a few questions. How many people will be staying in your RV? How much are you willing to spend on your water heater? Are you ok with spending extra time performing maintenance on your water heater? All these questions and a few more will play a big roll in deciding which water heater to purchase.
If you have a larger group you will want to go with the 10 gallon option, or you might even consider a 16 gallon water heater. That is completely up to your discretion. You then need to decide if you want an electric or propane heater. Both are solid options, but propane heaters are more versatile.
Most importantly, propane water heaters will work even if you have no electricity available. This can happen a lot when you are out in the woods or if your campground has generator time limits, which most do. So it is best to be prepared. Although they are more expensive initially, they will save you money in the long term. So, unless you cannot afford to pay a larger lump sum upfront, you should consider purchasing a propane water heater.
