    What to Look For in a RV Water Heater Buying Guide

    With so many various water heaters on the market, it might be difficult to choose the ideal one for your camper. Fortunately, there are a few considerations that might assist you in selecting the best RV water heater.

    Fuel Source


    Because it is safe and reasonably energy efficient, electricity is a popular method of powering water heaters in RVs. They’re also adaptable, as they can run on generator power or via an RV park connection. Electric RV water heaters, on the other hand, warm water slowly and might be costly to operate.

    Many RV water heaters may now operate on both electricity and liquid propane as needed. Campers will never run out of power again, even if they lose access to the grid or on-board energy.


    To provide hot water throughout the vehicle, most entry-level RVs, as well as many older vehicles, employ a liquid propane RV water heater. This is one of the oldest and most tried-and-true heating methods. While liquid propane is dependable, it is not the most energy-efficient or cost-effective option. It also poses more risks than other types of heating systems.

    There are two types of liquid propane heaters: those with a manual pilot light and those with direct spark ignition. A manual pilot light must be manually restarted when it burns out, whereas a direct spark ignition system detects and operates an igniter automatically.

    Natural Gas

    Natural gas is gaining popularity as a source of house heating these days. It is both energy-efficient and environmentally friendly.Despite having around one-third the energy density of propane, it is not easily available in a tank at the consumer level.

    However, if you have a motorhome that you park for the season at an RV park or campground that has natural gas, a natural gas tankless water heater may be on your radar.


    Tank heaters typically have a holding capacity of 6 to 10 gallons. In general, the size of the heater you select will be determined not just by space limits, but also by the number of people traveling in your RV. With more people, you may need a larger tank to avoid running out of hot water.

    Some RV water heaters advertise 16-gallon tanks, but this isn’t always the case. While tankless heaters can deliver a larger quantity of hot water, the tank itself is only about 10 gallons. To make the water stay longer, it is heated to severe degrees and then blended with cold water. When determining the size of a heater, the recovery rate is also significant. This is the amount of water that a tank heater can provide within an hour of being drained. Larger heaters recover at a slower rate because it takes longer to heat the volume of water inside.

    Easy to Install

    Your water heater, whether tanked or tankless, should be simple to install. Examine the manufacturer’s installation instructions as well as other customer reviews to determine your level of comfort with DIY installation. All of our best picks should be quite simple to install on your own.

    Tank or Tankless

    The most important question looming over this entire process is whether you should go tank or tankless. As previously stated, there are advantages and disadvantages to falling on either side of this debate. Tank-based models, for example, will get the job done while costing substantially less than a tankless model upfront. However, these types are larger and take up more room, and they do not provide the technological upgrades that a tankless unit would.

    Energy Consumption

    Many RV owners are concerned about energy efficiency, especially when it comes to appliances like water heaters. Unless you have access to a power outlet, you will most likely have to limit your energy consumption. Tankless water heaters are the most energy-efficient since the heating element is only activated when needed. While it may appear contradictory, propane heaters are also more energy-efficient than electric heaters, with motoraid types being the most efficient of them.

    A water heater’s heating capacity also has an impact on energy efficiency. This rating is expressed in British Thermal Units, abbreviated as BTUs. The higher the rating for heating capacity, the more efficient a unit is. Most RV water heaters have a BTU rating of 30,000 to 50,000.

    If you have an outdated water heater, no matter what type it is, replacing it is one of the finest things you can do to lower your energy consumption. Every day, technology advances, and modern RV water heater types tend to use far less energy than ones produced a decade or two ago. You can make your next camping trip more comfortable with the correct water heater for your camper.

    Frequently Asked Questions

    How to install a RV water heater?

    Installing a tankless water heater in your RV actually involves mounting your selected unit, connecting the gas, water and electricity lines and installing the exhaust duct. However, it should be noted that if you can perform the mentioned steps manually, it is a bit dangerous if you do not do it properly and are not familiar with the whole process. In this case, it would be best to seek help from a qualified and licensed professional installer who is able to comply with local plumbing, electrical, gas and ventilation codes. That way, you don’t end up working with an unwanted installed and unprofessional water heater.

    How to turn on a RV water heater?

    You need simple steps to turn on your RV’s water heater. In most cases, this involves testing the unit bypass soup first, after it has flowed into the primary tank of water after opening. Your next choice is to link your RVT to the nearest water price. With an on-board pump, you can start pumping water. This is also a good time to open the hot water faucet. Once lit, you can wait for water to flow through the heating tank line. Make sure it fills the line so that the water heaters are ready to operate.

    How to convert RV water heater to tankless?

    Converting your RV water heater to a tankless model necessitates advance preparation. This change is actually advantageous because it allows you to save more money on heating expenditures. Make sure you carefully plan everything, from selecting the correct heater to gathering the necessary tools and calculating the total cost of the purchase and installation.

    After you’ve properly planned everything, you may begin changing your RV’s water heater to tankless. To avoid problems later on, if possible, enlist the assistance of a competent installation service provider.

    Can I Put A Bigger Water Heater In My Camper?

    If you can fit a larger water heater, then you can definitely put a bigger water heater into your camper. This is a great way to get more hot water if you use a tanked water heater, or if you need more instant hot water, as some tankless heaters can run two appliances at once. Having a larger tankless water heater will also put less “strain on the system” and can be more efficient.
