Introduction: The Rise of Dual Fuel Generators
Power outages, severe weather, and the need for portable energy have made generators a household necessity. Dual fuel generators—which can run on both gasoline and propane—have become especially popular for their flexibility. Westinghouse, a trusted name in power equipment, has been at the forefront of this trend, offering a range of dual fuel models that are reliable, user-friendly, and affordable.
But as natural gas becomes more accessible and attractive for home energy, many users wonder if their Westinghouse dual fuel generator can tap into this clean, abundant resource.
How Do Westinghouse Dual Fuel Generators Work?
A Westinghouse dual fuel generator is designed to operate on two types of fuel: gasoline and propane (LPG). Here’s how it works:
- Gasoline Mode: The generator draws fuel from its built-in gasoline tank. Gasoline is widely available and provides high energy output, making it suitable for heavy loads and extended use.
- Propane Mode: The generator connects to an external propane tank via a hose and regulator. Propane burns cleaner than gasoline, has a longer shelf life, and is often preferred for its convenience and lower emissions.
A fuel selector switch allows users to choose the desired fuel source before starting the engine. Most Westinghouse dual fuel generators require the engine to be off before switching fuels.
What Fuels Do Westinghouse Dual Fuel Generators Use?
By default, Westinghouse dual fuel generators are designed to run on:
- Gasoline
- Propane (LPG)
They are NOT designed to run on natural gas out of the box.
The fuel system, carburetor, and regulators are specifically engineered for gasoline and propane, which have different pressure and combustion characteristics compared to natural gas.
Natural Gas: The Third Fuel
Natural gas is a popular fuel for whole-house standby generators and some commercial units. It is delivered via underground pipelines, providing a virtually unlimited supply during most emergencies (unless the gas utility is disrupted).
Advantages of Natural Gas
- Unlimited Supply: As long as the utility is operational, you have continuous fuel.
- Clean Burning: Produces fewer emissions than gasoline or diesel.
- No Refueling Needed: No need to store or transport fuel tanks.
- Lower Cost: Often cheaper per BTU than gasoline or propane.
Disadvantages of Natural Gas
- Not Portable: Requires a fixed connection to a gas line.
- Utility Dependent: If the gas utility is disrupted, you lose your fuel source.
- Lower Energy Density: Slightly less power output compared to gasoline.
Can a Westinghouse Dual Fuel Generator Run on Natural Gas?
The Short Answer
No, a standard Westinghouse dual fuel generator cannot run on natural gas out of the box.
It is designed specifically for gasoline and propane. The fuel system, carburetor, and regulators are not set up for natural gas, which has different pressure and combustion characteristics.
Why Not?
- Pressure Differences: Propane is stored as a liquid under pressure and vaporizes for use, while natural gas is delivered at a much lower pressure.
- Carburetor Design: The air-fuel mixture requirements for natural gas differ from those for propane and gasoline.
- Regulation and Safety: The regulators and safety systems are tuned for propane and gasoline, not natural gas.
What About “Tri-Fuel” Generators?
Some generators are marketed as tri-fuel generators, capable of running on gasoline, propane, and natural gas. These units have specialized carburetors and regulators to handle all three fuels safely and efficiently. As of 2024, Westinghouse does not offer a tri-fuel generator in their consumer lineup.
Tri-Fuel Generators: The True Natural Gas Option
If you want a generator that can run on natural gas, you need a tri-fuel generator. These are designed from the factory to operate on gasoline, propane, and natural gas, with the appropriate fittings, regulators, and carburetor modifications.
How Do Tri-Fuel Generators Work?
- Selector Switch: Lets you choose between gasoline, propane, or natural gas.
- Dedicated Regulator: Handles the lower pressure of natural gas.
- Carburetor Adaptation: Special jets or adapters ensure the correct air-fuel mixture for each fuel.
Examples of Tri-Fuel Generators
- DuroMax XP13000HXT: A popular tri-fuel model for home backup.
- Firman H08051: Another well-known tri-fuel generator.
- Champion 100416: A tri-fuel portable generator.
Converting a Westinghouse Dual Fuel Generator to Natural Gas
If you already own a Westinghouse dual fuel generator and want to use natural gas, you may be able to convert it using an aftermarket tri-fuel conversion kit. These kits typically include:
- A carburetor adapter or replacement.
- A natural gas regulator.
- Hoses and fittings for natural gas connection.
Steps for Conversion
- Purchase a Compatible Kit: Make sure it’s designed for your generator model.
- Install the Adapter: This may involve removing the carburetor and installing a new one or adding a spacer.
- Connect the Regulator: Attach the natural gas regulator to your home’s gas line.
- Test for Leaks: Use soapy water to check all connections.
- Adjust the Air-Fuel Mixture: Some kits require fine-tuning for optimal performance.
Important:
- Professional Installation Recommended: Incorrect installation can be dangerous.
- Warranty Void: Modifying your generator may void the manufacturer’s warranty.
- Local Codes: Always comply with local building and safety codes.
Should You Convert?
- Pros: Unlimited run time, no need to store fuel, cleaner emissions.
- Cons: Not portable, may void warranty, requires professional installation, and may reduce power output.
Pros and Cons of Running Generators on Natural Gas
Pros
- Unlimited Run Time: As long as the gas utility is operational.
- No Refueling Hassles: No need to store or transport fuel.
- Cleaner Emissions: Less carbon monoxide and particulates.
- Lower Cost: Natural gas is often cheaper than gasoline or propane.
Cons
- Not Portable: You can’t take your generator camping or to a job site unless there’s a gas line.
- Lower Power Output: Natural gas has a lower energy density, so expect a slight drop in wattage.
- Utility Dependent: If the gas supply is interrupted, you lose your backup power.
- Complex Installation: Requires proper fittings, regulators, and sometimes permits.
Safety and Legal Considerations
Safety
- Carbon Monoxide: Never run any generator indoors or in enclosed spaces.
