Tankless RV Water Heater Benefits and Considerations

Tankless RV water heaters are a game-changer for RV enthusiasts, offering a more efficient and space-saving alternative to traditional tank-style water heaters.

They can provide a continuous supply of hot water, unlike traditional tank-style water heaters which have a limited capacity and can run out of hot water during peak usage.

Tankless RV water heaters can be more energy-efficient, using less energy to heat the water as needed, rather than constantly heating a full tank of water.

This can result in significant energy cost savings, especially for full-time RVers or those who boondock frequently.

You can upgrade to a tankless water heater without breaking the bank or sacrificing too much space. These units typically require less space than traditional models.

Some tankless water heaters can be retrofitted in the same space that housed your old water heater, making the installation process much simpler. Many manufacturers offer retrofit kits to help with a safe and aesthetically pleasing installation.

You'll need to schedule a service appointment for this upgrade, as you'll need to safely disconnect propane and shut off your electricity to install an RV propane tankless water heater. Service technicians will ensure proper installation location and adherence to all codes and regulations regarding proper water heater ventilation.

If you occasionally RV in locations that drop below 32℉, you may want to consider installing an antifreeze kit with your new tankless water heater.

Winterizing is a crucial step to protect your RV from freeze damage. Freezing temperatures can be devastating to your water system, so it's essential to take preventative measures.

If you upgrade to a tankless water heater, the winterizing process changes slightly. A basic winterizing process uses air to blow out water lines, but a small amount of water will always remain.

This remaining water can destroy a tankless water heater if temperatures drop below 32℉. To prevent this, you need to add RV-safe antifreeze to the water lines.

We recommend choosing the Delux Winterize package, available at any Camping World Service Center. This package requires pumping RV antifreeze through your entire fresh water system to displace water and protect everything from freeze damage.

Removing the bypass valves on your standard water heater is also crucial when retrofitting a tankless model. These valves serve no purpose for a tankless design and can sometimes lead to confusion when winterizing your RV at home.

You'll want to choose a tankless water heater with a display that you can easily operate. This will make it simpler to adjust settings and troubleshoot any issues.

Compatibility with your existing systems is also essential. If you're replacing a broken heater, sticking with the same manufacturer can be a convenient option.

Functioning is where things can get a bit tricky with RV tankless water heaters. They create a thermodynamic pathway that's activated by the forward momentum of pressurized cold water flowing through the heating system.

A tankless water heater's operation can be affected by the number of open hot water taps, which can cause it to shut off and leave you with an icy shower. This is because the sudden decrease in water flow can confuse the system.

Most RV tankless water heaters have intelligent control panels that allow you to adjust the desired output temperature setting. This is a key feature for maintaining consistent hot water temperatures.

A tankless water heater capable of producing 40,000-50,000 BTUs at a rate of 2-4 GPM is generally sufficient for most campers, with a maximum PSI of 50. This is according to the mathematical relationships among water pressure, flow rate, and heat exchange.

First-generation RV tankless water heaters were more prone to variations in water flow and temperature, but modern models have addressed these concerns with the incorporation of microprocessors that monitor water flow and temperature.

Here's a rough breakdown of the costs:

Unfortunately, there are limited options for RV owners when it comes to water heaters. Currently, there are no electric tankless water heater options available for RVs.

The main reason for this is the high power required to heat water at a 2-4 GPM rate, which is around 40,000 BTUs. This requires at least 240 volts of power, which is not feasible with the current electric systems in RVs.

As a result, all RV tankless water heaters rely on propane. This can be inconvenient for RV owners who are used to the convenience of electric appliances, especially when they're paying for full hookups.

Tankless RV water heaters are a great way to go off-grid, but you'll need to think about how you'll power them. Most tankless water heaters require a dedicated 120-volt electrical circuit.

The good news is that many RVs already have a 120-volt electrical system, which can support a tankless water heater. However, you'll need to ensure that your RV's electrical system can handle the additional load.

A typical tankless water heater uses between 4 and 6 gallons of propane per hour of operation. This can add up quickly, especially if you're planning to use your RV's shower frequently.
