How to Convert a Natural Gas Water Heater to Propane
If you’re looking to convert your natural gas water heater to propane, there are a few things you need to know. While the process may seem daunting, it’s actually relatively straightforward, and can be done with a few simple steps. In this article, we’ll give you a step-by-step guide on how to convert a natural gas water heater to propane.
Why Convert a Natural Gas Water Heater to Propane?

Before we dive into the conversion process itself, let’s first discuss why you might want to convert your natural gas water heater to propane. There are a few reasons why someone might want to make this switch:
1. Availability of Fuel
The first reason you might want to convert your natural gas water heater to propane is if you don’t have natural gas service available in your area. Propane is a more widely available fuel source and can be delivered to your home in tanks or through a gas line.
2. Cost
Another reason you might want to convert to propane is if it’s cheaper than natural gas in your area. The cost of natural gas can vary depending on where you live, but propane is often cheaper in rural areas where natural gas lines don’t reach.
3. Efficiency
Finally, propane is often considered more efficient than natural gas because it burns hotter, which means that your water heater may be able to heat up your water more quickly.
What You’ll Need to Convert a Natural Gas Water Heater to Propane

Now that we’ve discussed why you might want to convert your natural gas water heater to propane, let’s talk about what you’ll need to make the conversion. Here’s a list of items you’ll need:
1. Propane Conversion Kit
The first thing you’ll need is a propane conversion kit. This kit typically includes a new gas valve, burner orifices, and a regulator.
2. Wrenches and Screwdrivers
You’ll also need a set of wrenches and screwdrivers to remove the old gas valve and install the new one.
3. Pipe Dope
Pipe dope is a type of sealant that you’ll need to use to seal the threads of the new gas valve.
4. Propane Tank
Finally, you’ll need a propane tank to supply fuel to your water heater. You can either use a small propane tank that you can refill or exchange at a local hardware store, or you can have a larger tank installed outside your home that’s connected to your water heater through a gas line.
How to Convert a Natural Gas Water Heater to Propane
Now that you have all the items you need to convert your natural gas water heater to propane, it’s time to get started. Here are the steps you’ll need to follow:
1. Turn Off the Gas and Water Supply
The first step is to turn off the gas and water supply to your water heater. You can do this by turning off the gas valve and shutting off the water valve that’s connected to your water heater.
2. Remove the Gas Valve
The next step is to remove the old gas valve from your water heater. You’ll need to use a wrench to loosen the nuts that are holding the valve in place. Once the nuts are loose, you can remove the valve from the water heater.
3. Install the Propane Conversion Kit
Now it’s time to install the propane conversion kit. Follow the instructions that come with the kit to install the new gas valve, burner orifices, and regulator.
4. Connect the Propane Tank
Once the conversion kit is installed, you can connect the propane tank to your water heater. If you’re using a small propane tank, you’ll need to connect it to the regulator that came with the conversion kit. If you’re using a larger tank that’s installed outside your home, you’ll need to connect the gas line to the regulator.
5. Test the Water Heater
Finally, it’s time to test your water heater to make sure everything is working correctly. Turn on the gas and water supply and light the pilot light. Let the water heater run for a few minutes to make sure the water is heating up properly.
Safety Precautions
While converting a natural gas water heater to propane is a relatively simple process, it’s important to take some safety precautions to avoid any accidents. Here are some things to keep in mind:
1. Turn Off the Gas and Water Supply
Before you start the conversion process, make sure you turn off the gas and water supply to your water heater. This will prevent any gas or water from leaking out during the conversion process.
2. Use Pipe Dope
Make sure you use pipe dope to seal the threads of the new gas valve. This will help prevent any gas leaks.
3. Check for Leaks
Once the conversion is complete, check for any gas leaks by spraying a soapy water solution on the gas connections. If you see bubbles forming, that’s a sign of a gas leak. Turn off the gas supply immediately and tighten the connection.
4. Have a Professional Install a Larger Propane Tank
If you’re installing a larger propane tank outside your home, it’s best to have a professional do the installation. They’ll be able to make sure everything is installed correctly and safely.
By following these safety precautions, you can ensure that your conversion process goes smoothly and safely.
