What is a Tankless RV Water Heater?<\/h2>\n\n\n\n

A Tankless RV water heater, also called a tankless hot water heater for RV, heats water as soon as you turn on the hot water faucet. An instant RV water heater<\/a> heats the water as it flows through the pipes inside the heater rather than heating an entire tank of water. This is a water heater that you need for your camping and other family activities.<\/p>\n\n\n\n

Why Switch to a Tankless Water Heater?<\/h2>\n\n\n\n

When staying at a full-service campground, the main reason campers prefer a tankless water heater for a camper over a standard model is that you get endless hot water. This is ideal for large families or people who travel full-time. <\/p>\n\n\n\n

You don’t have to limit your shower duration to save hot water with a tankless heater that provides on-demand hot water with no recuperation period. As a result, you won’t have to waste money boiling water in a tank that you may or may not use. You also won’t have to wait hours for the water to warm up again between each individual having a shower.<\/p>\n\n\n\n

With a tankless water heater, you can pre-set your water temperature. The ability to pre-set your water temperature has both advantages and disadvantages. Some campers prefer the security of knowing that you will always set the water in the shower or sink to their preferred temperature. However, if different family members favor different heat levels, it can be inconvenient.<\/p>\n\n\n\n

Tankless water heaters weigh less. When you’re constantly on the go, every pound counts. Compared to factory-installed water heaters, tankless water heaters are lighter. Full-timers, large families, and campers who want to take long showers or consume a lot of hot water on demand should utilize tankless water heaters.<\/p>\n\n\n\n

Disadvantages of Tankless Hot Water Heaters for RVs<\/h2>\n\n\n\n

There are numerous advantages to going tankless, but they are not for everyone. Many RV campers continue to favor propane or propane-electric heaters. The following are some of the drawbacks of going tankless:<\/p>\n\n\n\n

  1. Delays in heating water: <\/strong>The most significant disadvantage of on-demand water is the time it takes for heat to be provided. Every time you turn on the faucet, you may expect a 3-5 second delay before the water gets hot. Although five seconds may not seem like much, there is a significant amount of water lost when boondocking. Consider what it’s like to take a military shower. You run the water for a few seconds before rinsing and turning it off. After that, soap up again and continue the process. You’ll have little to no hot water at that time, or you’ll be squandering water. You don’t want to do either of these things off the grid.<\/li>
  2. They use more propane<\/strong>: As a result, if water conservation is vital to you, we do not advocate going tankless. When you go from an electric heater to a propane tankless water heater for RV, you’ll need a lot more propane! Because you’ll have endless hot water, you’ll be more likely to use it. Although we believe the benefits outweigh the costs, it is something to consider. Water temperature pre-setting option: As previously said, the option to pre-set your water temperature can be beneficial or detrimental. Because the control panel isn’t right next to the shower, you’ll have to remember to do so ahead of time if you need to change the temperature regularly.<\/li>
  3. Low efficiency in certain conditions<\/strong>: Propane heaters are less efficient in specific settings, such as low temperatures or high elevations than electric heaters.<\/li>
  4. They can be costly<\/strong>: Upfront, a camper tankless water heater might be more expensive than traditional RV water heaters. If you do a lot of boondocking, are on a budget, or go camping infrequently, we recommend sticking with a tanked heater.<\/li><\/ol>\n\n\n\n

    How to Install a Tankless Water Heater in Your RV<\/h2>\n\n\n\n

    In an RV, the installation is pretty simple. To begin, find a tankless heater that is the same size as your existing water heater. You’ll also need to buy a door, which is available separately. To be sure you’re obtaining the appropriate size, measure the length and width of your outer compartment.<\/p>\n\n\n\n

    Then it’s time to put it all together!<\/p>\n\n\n\n

    1. Turn off the propane, water pressure pump, and power.<\/li>
    2. Open the pressure relief valve and drain valve to drain the hot water tank.<\/li>
    3. Disconnect the old water heater’s gas line, hot and cold-water lines, and electric connections. Please take a photo of the current connections so you can remember how to reconnect them later.<\/li>
    4. Remove the old unit by unscrewing it and unscrewing the screws.<\/li>
    5. Scrape off and remove any remaining caulking, then clean up any residue.<\/li>
    6. Wrap new butyl tape across the outside compartment’s entrance.<\/li>
    7. Replace the old tankless heater with the new retrofit tankless heater.<\/li>
    8. Install the new door.<\/li>
    9. Apply a bead of lap sealant around the unit’s perimeter.<\/li>
    10. Connect the gas and water lines again. If the current water lines do not match, you can connect them with flexible PEX tubing. On a camper tankless water heater, you do not require bypass valves.<\/li>
    11. Place the new heater control panel on the interior of the RV in a convenient location.<\/li>
    12. Reconnect the electrical connections that are already in place.<\/li>
    13. Check for leaks by turning on the water pump and LP gas lines.<\/li>
    14. Test your water heater by turning on the electricity.<\/li><\/ol>\n\n\n\n

      Tips for Troubleshooting<\/h3>\n\n\n\n

      If there is air in the gas line, your new water heater will probably not switch on. You may eliminate the mood by turning on the stovetop burner and letting it run for a few seconds. Another reason why the water does not come out hot is if the flow rate of the faucet or showerhead is too low.<\/p>\n\n\n\n

      Turning the taps on full blast, bleeding air from the water pipes, removing any water restrictors, and running only one water appliance at a time may be necessary to kick-start the water heater.<\/p>\n\n\n\n

      Your RV Tankless Hot Water Heater Buying Guide<\/h2>\n\n\n\n

      Whenever you want to buy a tankless water heater, consider the following:<\/p>\n\n\n\n

      1. Brand: <\/strong>Atwood, Suburban, and Girard are the best tankless water heater RV brands on the market today. You don’t have to acquire the same brand as the one in your RV; all you need is the right size. These models are all retrofitted and should work with your existing camper.<\/li>
      2. Size: <\/strong>Tankless water heaters are designed to replace your existing heater. In addition, you’ll need to measure and buy a new door, which is supplied separately.<\/li>
      3. Rate of Flow (GPM): <\/strong>The flow rate is in gallons per minute (GPM) (GPM). Once it meets a minimal flow rate, a tankless water heater for RV detects the input flow rate and lights the burner. The flow rate of a water heater is often too low to ignite the burner, which is a common complaint. To enhance the flow rate, do the following:<\/li><\/ol>\n\n\n\n
