Choosing a Tankless Water Heater for Your RV

Considerations before installation

When choosing a tankless water heater for your RV, there are a few important considerations to keep in mind. First and foremost, you’ll need to determine the fuel source for your water heater. Tankless water heaters can be powered by either propane or electricity, so make sure you have access to the appropriate fuel source.

Next, you’ll need to consider the size and capacity of the tankless water heater. RV tankless water heaters come in various sizes and flow rates, so it’s essential to choose one that meets your specific needs. Consider factors such as the number of people traveling in your RV, your hot water usage habits, and the climate conditions you’ll be camping in.

Additionally, it’s important to think about the installation requirements for the tankless water heater. Some models may require additional venting or clearance space, so ensure that your RV has the necessary provisions before making a purchase. Taking these considerations into account will help you choose the right tankless water heater for your RV.

Types of tankless water heaters

There are two main types of tankless water heaters commonly used in RVs: propane-powered and electric. Propane-powered tankless water heaters are a popular choice among RV owners due to their energy efficiency and convenience. They use liquid propane fuel to heat the water as it flows through the unit, providing an instant supply of hot water.

On the other hand, electric tankless water heaters are powered by electricity and do not require a propane supply. These units are typically more compact and easier to install, making them a great choice for smaller RVs or those without a propane hookup. However, it’s important to note that electric tankless water heaters may have a slightly lower flow rate compared to their propane counterparts.

Ultimately, the choice between propane and electric tankless water heaters will depend on your RV’s specific needs and your personal preferences.

Sizing your tankless water heater

When it comes to sizing your tankless water heater, it’s crucial to choose a unit that can meet your hot water demands without running out of supply. To determine the appropriate size, consider factors such as the number of people using hot water simultaneously, the number of fixtures you’ll be supplying with hot water, and the temperature rise required.

When calculating the required flow rate, consider the flow rates of your showerheads, faucets, and other fixtures to ensure that the tankless water heater can handle the demand. It’s important to note that undersizing the water heater may result in inadequate hot water supply, while oversizing can lead to unnecessary energy consumption.

Consult the manufacturer’s specifications and guidelines when selecting the size of your tankless water heater to ensure optimum performance and efficiency.

Installation Process

Disconnecting the old water heater

Before installing the new tankless water heater, you’ll need to disconnect and remove the old water heater, if there is one. Start by turning off the water supply and gas or electricity to the old water heater.

Next, disconnect the water supply lines and drain any remaining water from the system. Finally, disconnect the gas supply line or electrical connections, depending on the type of water heater you’re replacing.

Preparing the area for installation

Once the old water heater is disconnected and removed, it’s time to prepare the installation area for the new tankless water heater. Clean the space and ensure that it is clear of any debris or obstructions. If necessary, make any structural modifications or adjustments to accommodate the new unit.

Mounting the tankless water heater

Follow the manufacturer’s instructions to mount the tankless water heater securely in the designated location. Use the provided mounting hardware and ensure that the unit is level and properly supported.

Connecting water supply lines

Connect the water supply lines to the tankless water heater by using appropriate pipe fittings and connectors. Apply Teflon tape or pipe dope to the threaded connections to create a watertight seal. Make sure to follow the manufacturer’s guidelines for the proper installation of the water supply lines.

Connecting gas supply lines

If you’re using a propane-powered tankless water heater, you’ll need to connect the gas supply lines. Use a pipe cutter to cut the gas lines to the appropriate length and connect them to the water heater using compression fittings or other approved connection methods. Again, consult the manufacturer’s instructions for specific guidelines and safety precautions.

Installing venting system

Some tankless water heaters may require a venting system to properly exhaust combustion gases. If your unit requires venting, follow the manufacturer’s instructions to install the venting system correctly. Ensure that the venting components are properly aligned and securely fastened to prevent any leaks or obstructions.

Testing the installation

Once the tankless water heater is fully installed, it’s crucial to test the installation to ensure proper functioning and safety. Turn on the water supply and gas or electricity to the unit and check for any leaks or abnormal sounds. Adjust the temperature settings and test the hot water flow from various fixtures to ensure that everything is working correctly.

Benefits of Tankless Water Heaters for RVs

Continuous hot water supply

One of the significant advantages of tankless water heaters for RVs is the ability to provide a continuous supply of hot water. Unlike traditional tank water heaters that can run out of hot water, tankless systems heat the water as it flows through, ensuring a consistent temperature throughout your RV adventures.

Space-saving design

RVs often have limited space, and tankless water heaters are known for their compact and space-saving designs. By eliminating the need for a large storage tank, tankless water heaters free up valuable storage space in your RV. This can be especially beneficial for RV owners who prioritize maximizing interior space.

Energy efficiency

Tankless water heaters are more energy-efficient compared to traditional tank water heaters. They only heat the water when it’s needed, eliminating the standby heat loss that occurs in tank systems. This energy-saving feature can lead to reduced fuel consumption and lower energy bills during your travels.

Longer lifespan

Tankless water heaters generally have a longer lifespan compared to traditional tank water heaters. With proper maintenance and care, tankless units can last up to 20 years or more, providing long-term durability and reliability for your RV.

Reduced risk of leaks and water damage

Traditional tank water heaters are prone to leaks, which can lead to water damage and costly repairs. Tankless water heaters eliminate this risk by not storing water in a tank. With no water storage, the likelihood of leaks and water damage is significantly reduced, providing peace of mind during your travels.
