Water heater revolution: natural gas to propane in just a few steps
What To Know
- Converting a natural gas water heater to propane is a serious task that should only be performed by a qualified professional.
- While converting a natural gas water heater to propane is possible, it’s important to consider the benefits of using a propane water heater from the start.
- Ultimately, the decision of whether to convert a natural gas water heater to propane or to install a propane water heater from the start depends on your individual needs and circumstances.
Water heaters are an essential part of modern homes, providing us with a constant supply of hot water for showers, dishes, and more. However, not all water heaters are created equal. Some run on natural gas, while others use propane. If you’re considering replacing your current water heater, you may wonder if a natural gas water heater can be converted to run on propane. The answer is yes, but it’s not always as simple as it seems.
Understanding the Differences Between Natural Gas and Propane
Natural gas and propane are both flammable gases used for heating and cooking. However, there are some key differences between the two:
- Composition: Natural gas is primarily composed of methane, while propane is primarily composed of propane and propylene.
- Density: Propane is denser than natural gas and therefore has a higher BTU (British Thermal Unit) content.
- Pressure: Natural gas is typically supplied at a higher pressure than propane.
Converting a Natural Gas Water Heater to Propane
Converting a natural gas water heater to propane is possible but requires a few modifications:
- Change the Burner Assembly: The burner assembly is responsible for mixing the gas with oxygen and igniting it. A natural gas burner will not work with propane, so it must be replaced with a propane burner.
- Adjust the Gas Valve: The gas valve controls the flow of gas to the burner. It must be adjusted to deliver the correct amount of gas for propane.
- Change the Igniter: Some water heaters use a spark igniter, while others use a pilot light. If your water heater uses a spark igniter, it may need to be replaced with a propane-compatible igniter.
- Add a Propane Regulator: A propane regulator is necessary to reduce the pressure of the propane from the tank to the water heater.
Safety Considerations
Converting a natural gas water heater to propane is a serious task that should only be performed by a qualified professional. Improper conversion can lead to safety hazards, including:
- Gas Leaks: If the gas lines are not properly sealed, gas can leak into the home, creating an explosion risk.
- Carbon Monoxide Poisoning: Carbon monoxide is a poisonous gas that can be produced by incomplete combustion. If the water heater is not properly vented, carbon monoxide can build up in the home, leading to serious health problems.
- Fire: If the water heater is not properly installed, it could overheat and start a fire.
Benefits of Using Propane Water Heaters
While converting a natural gas water heater to propane is possible, it’s important to consider the benefits of using a propane water heater from the start:
- Energy Efficiency: Propane water heaters are typically more energy-efficient than natural gas water heaters.
- Lower Emissions: Propane burns cleaner than natural gas, producing fewer emissions.
- Portability: Propane water heaters can be used in remote locations where natural gas is not available.
Drawbacks of Using Propane Water Heaters
There are also a few drawbacks to consider:
- Higher Cost: Propane is typically more expensive than natural gas.
- Storage Requirements: Propane tanks require more space than natural gas lines.
- Safety: Propane is a flammable gas, so it’s important to take safety precautions when using it.
Making the Right Choice
Ultimately, the decision of whether to convert a natural gas water heater to propane or to install a propane water heater from the start depends on your individual needs and circumstances. If you’re considering making the switch, be sure to consult with a qualified professional to ensure the conversion is done safely and correctly.
Frequently Asked Questions
Q: Can I convert any natural gas water heater to propane?
A: No, not all natural gas water heaters can be converted to propane. Some models are not designed to handle the higher BTU content of propane.
Q: How much does it cost to convert a natural gas water heater to propane?
A: The cost of conversion will vary depending on the make and model of your water heater and the cost of labor in your area. Typically, you can expect to pay between $200 and $500.
Q: Is it safe to convert a natural gas water heater to propane myself?
A: No, it is not recommended to convert a natural gas water heater to propane yourself. This is a job that should be performed by a qualified professional to ensure the conversion is done safely and correctly.
