How to Operate Your RV Water Heater: A Comprehensive Guide

Traveling by RV is one of the most comfortable ways, as it incorporates novelty into a new place with the coziness of your home. Hot water makes all the difference in the world when it comes to your trips for showering, washing dishes, or just hygiene in general. You should understand how to turn the water heater on in your RV, and that's one of the keys to comfort in camping.

Overview of the Major Types of Water Heaters Used in RVs

Before explaining in detail how they work, here is a quick overview of the major types of water heaters in use in RVs:

1. Propane Water Heaters
   Propane water heaters are thus pretty common in RVs due to their effectiveness and speed of heating water. They work off propane gas and are, therefore, ideal for off-grid camping situations.

2. Electric Water Heaters
   These water heaters require your RV's electrical system to operate. Most of them come with newer models of RVs and take some considerable time to heat water when compared to propane units but are more convenient once connected to an electrical source.

3. Tankless Water Heaters
   These models provide instant hot water without any storage of the water. They heat up the water instantly on passing through the unit and are energy-efficient as well as saving space.

4. Pilot Water Heaters Manual
   Some of the older models of recreational vehicles make use of such a water heater, which requires manual ignition. Operating these models will also be of immense use to you in case you have an older RV.

How to Prepare for Turning On Your Water Heater

Before you begin turning on your water heater, here are a few things you can do:

Water Supply Check

Your tank should be full of water; if using city water, ensure the hose has been properly attached and that the water supply is on.

Power Supply Check

First and foremost, for electric water heaters, you need to make sure your RV's electrical system is fired up. If you are on a generator, make sure it is turned on.

Check the Gas Supply

For propane heaters, this will entail checking the propane tank to ensure that it is full and the connections are tight.

How to Turn On the Propane Water Heater in Your RV

Step-by-Step Guide

1. Locate the Water Heater Control Panel: This is generally located near a point like the kitchen or the bathroom area.
2. Turn On the Propane Supply: It has to be opened on the propane tank.
3. Turn On the Water Heater: The knob should be turned to the "On" position. On some units, at this stage, you would click a button to fire up the burner.
4. Status Light: If the burner has fired on it should indicate that through the status light. If this is not happening after a couple of minutes, then the system needs to be turned off and troubleshot.

How to Change an RV Water Heater from Propane to Electric

Changing from propane to electric is pretty simple. However, you should be certain that the power source will be present.

Step-by-Step Instructions

1. Turn the Propane Water Heater Off: It needs to be in the "Off" position and the pilot light off.
2. Find the Electric Control Switch: Normally this is located on the same panel as the propane switch.
3. Turn the Electric Water Heater On: The switch to the electric water heater needs to be flipped to "On."
4. Indicator Light Check: The light should now be on, which is a good assurance the unit is heating.

How to Turn On the Electric Water Heater in Your RV

Electric water heaters aren't very complicated and, in most models, it's just a matter of flipping a switch to turn it on.

Step-by-Step Directions

1. Locate the Control Panel: This is usually near the entry door or kitchen area.
2. Turn the Electric Heater On: Switch the toggle switch to the "On" position.
3. Wait for Heating: Give it some time and wait while water heats up. The pilot light would give you an indication that the heating element is okay.

How to Turn On Your RV's Tankless Water Heater

The tankless water heater is very efficient. The device provides hot water on demand. That may perhaps be one of many reasons why they are an indispensable part of the modern RV.

Step-by-Step Instructions

1. Turn a Hot Water Tap: It will activate the tankless water heater.
2. Select your Required Temperature: With the control panel, adjust accordingly the temperature of the water.
3. Hot Water: It automatically heats as the water starts to flow.

How to Turn On a Water Heater Manually with Pilot Ignition

Below is the procedure that needs to be followed in case an RV has a manual pilot ignition:

Step-by-Step Instructions

1. Identify the location of the Pilot Light Access: Usually, it is near or around the water heater unit.
2. Rotate the Gas Control Knob to 'Pilot': This opens the gas intake by the pilot light.
3. Press the Ignition Button: While pressing the gas knob down, at the same time press the ignition button, and the pilot light should fire up.
4. Continue Holding the Knob: For about 30 seconds. This allows the thermocouple to heat up a bit.
5. Set the Gas Control Knob to 'On': Once the pilot light has steadied, you can let go of the knob and the pilot light, while still "on," will no longer need to be depressed and should just burn steadily. At this stage, the heat to the water is on.

Some Easy Troubleshooting

1. Water Heater Won't Heat

   • Check Propane or Electrical Supply: Make sure you have gas supplied or are plugged into an electrical outlet.
   • For Propane Units Only: Make sure burner is lit. This may be verified by viewing light on unit.

2. Water Temperature is Hot/Cold

   • Reduce the Flow Rate: If temperature of water changes try lowering the flow at the hot water faucet.

3. No Hot Water at All

   • Check Settings: Understand that the heater is on and the water tank is filled if traditional units are in use.
   • For Tankless Units: If using a tankless unit, ensure at least one faucet for hot water has been left open.

Safety Precautions

Always follow every safety precaution recommended in your RV's owner manual. If you suspect a gas leak or smell propane, shut the gas supply off right away and seek help.

Maintenance and Care

1. Periodic Checks
   Check your water heater periodically for proper operation. Look for wear, leaks or corrosion.

2. Seasonal Maintenance
   Winterize the water heater by draining in freezing months. Long term storage of the system could be aided by the use of RV antifreeze.
