Consider Portability: Wheel kits are essential for heavy units; know your transport limits.
Plan for Connection: Most high-capacity generators require professional transfer switch installation.

The Dual Fuel Advantage: Why Versatility Matters

A dual fuel generator is exactly what it sounds like: a power generator capable of running on two different fuel sources, typically gasoline and liquid propane. This isn't just a fancy feature; it's a significant strategic advantage, especially for home backup.
Think about it: during a widespread power outage, gasoline can become scarce and lines at the pump grow impossibly long. With a dual fuel unit, you have the option to switch to propane, which can be stored safely for much longer periods and might be more readily available from multiple sources. This flexibility greatly extends your potential runtime and reduces your reliance on a single, potentially compromised fuel supply.
Propane also offers a cleaner burn, leading to less engine wear and tear over time, and it's less prone to spills. Gasoline, on the other hand, often provides a slightly higher wattage output and is universally available in normal times. Having both options means you're prepared for more scenarios.
Critical Safety Reminder: Regardless of the fuel type, all portable generators—dual fuel included—produce toxic carbon monoxide fumes. They must always be operated outdoors in a well-ventilated, sheltered area, far from windows and doors. Never run a generator in a garage, basement, or any enclosed space.

Decoding Power: Watts, Peak, and Running

When generator shopping, you'll encounter two main wattage figures: "peak power" (or "surge watts") and "running power" (or "continuous watts").

Peak Power: This is the maximum output a generator can provide for a short burst, typically needed to start motors that have a high initial current draw (like refrigerators, well pumps, or air conditioners).
Running Power: This is the steady, continuous wattage the generator can produce consistently over time to keep your appliances operating.
Always focus on the running power when matching a generator to your actual needs, but be sure the peak power is sufficient for any motor-driven appliances you plan to start simultaneously. Westinghouse generators clearly delineate these figures, making it easier to compare models.

How Much Power Do You Really Need?

This is the most crucial question. Don't just guess; take a moment to tally up your home's essential loads.

Identify Critical Appliances: What absolutely must run during an outage? Think refrigerator, freezer, well pump, furnace fan, lights, charging phones, medical equipment.
Find the Wattage: Look for wattage labels on your appliances (often on the back or bottom). For motors, note both running and starting (surge) watts.
Calculate Your Total:

Add up the running watts of all critical items you want to power simultaneously.
Identify the single highest starting wattage appliance. Add this to your total running watts (but only once, for the largest motor).
Example Scenario:
Refrigerator: 800 running watts, 2000 starting watts
Furnace Fan: 600 running watts, 1500 starting watts
Lights (various): 500 running watts
Phone Chargers: 100 running watts
Calculation: (800 + 600 + 500 + 100) running watts = 2000 running watts.
Highest starting watt appliance (refrigerator) = 2000 watts.
Total minimum generator running watts needed: 2000 watts.
Total minimum generator peak watts needed: 2000 (running total) + 2000 (highest starting surge) - 800 (running watt of that same appliance) = 3200 watts.
It's always better to slightly overestimate than underestimate. A generator that's too small will be constantly overloaded, potentially damaging both the generator and your appliances. When exploring various Westinghouse dual fuel generators, keep your wattage calculations handy.

Beyond the Watts: Key Features to Consider

Once you have a general idea of your power requirements, delve into the features that define a generator's usability, safety, and overall value.

Starting Mechanisms: Effortless vs. Dependable

Electric Start: A simple push-button or switch, typically powered by an onboard battery. This is a game-changer for ease of use, especially if you need to start the generator quickly or in inclement weather. Most modern Westinghouse units feature this.
Recoil Start: The classic pull-cord. It's reliable, doesn't depend on a battery, and serves as an excellent backup for an electric start. It's crucial for generators stored for long periods.
Remote Key Fob Start: The ultimate convenience, allowing you to start the generator from inside your home (though you'll still need to go outside for refueling and safety checks). Some Westinghouse models offer this.

Noise Levels: Your Neighbors (and Ears) Will Thank You

Generators, by their nature, are loud. Their noise level is measured in decibels (dB).

Typical Conventional Generator: 65-75 dB, comparable to a normal conversation or a vacuum cleaner. Louder models can reach 90 dB (like a hair dryer or motorcycle).
Inverter Generators: These are significantly quieter, often as low as 52 dB, similar to a refrigerator. If you're in a close-knit neighborhood, camping, or just prefer peace and quiet, an inverter is a strong contender.
Keep in mind that gasoline operation is generally louder than propane. Always check the dBA rating before you buy, especially if noise is a concern.

Fuel Capacity & Runtime: How Long Will It Last?

Gasoline: Generators come with integrated fuel tanks ranging from 2 to over 10 gallons. A larger tank means longer runtime between refills.
Propane: Propane is stored in external tanks (e.g., 20-pound BBQ tanks), offering flexibility but requiring you to manage multiple canisters.
Runtime is typically measured at 25% or 50% load. Always consider your expected load to gauge realistic runtime. The beauty of dual fuel is that you can often use both sequentially to extend your total power duration.

Portability: Moving a Mini Power Plant

Generators are heavy beasts, often weighing 100-250+ pounds, with some exceeding 350 pounds.

Wheel Kits: Essential. Look for sturdy, flat-free wheels capable of handling varied terrain.
Lift Bars: Some heavy-duty models designed for jobsites include lift hook bars for crane or winch transport.
Ergonomics: Consider handle design and how easily you can maneuver the unit. Think about how you'll get it in and out of storage or a vehicle.

Outlets & Connectivity: Powering Your World

A generator is only as useful as its outlets.

120V Standard Outlets (20A GFCI): Your typical household outlets, usually several are included. GFCI (Ground-Fault Circuit Interrupter) outlets offer enhanced safety.
120V/240V Twist-Lock Outlets (30A or 50A): These are for higher-capacity appliances or for connecting to a transfer switch (often called RV outlets, TT-30R for 30A, or L14-30R/L14-50R for 30A/50A locking).
USB Ports: Common on inverter generators, perfect for charging sensitive electronics like phones and tablets without needing an adapter.

Safety First: Essential Protective Features

Never compromise on safety. Look for these crucial features:

Carbon Monoxide (CO) Sensors: A life-saving feature that automatically shuts down the generator if CO levels become dangerously high. Many modern Westinghouse generators include this.
Overload Protection: Prevents damage to the generator and connected appliances if you try to draw too much power.
Automatic Low Oil Shut-Off: Protects the engine from damage by turning off the generator if oil levels drop too low.
Circuit Breakers: Standard on all generators, protecting outlets from surges.

Connecting Your Generator to Your Home: Do It Right, Do It Safely

A powerful dual fuel generator can provide significant backup, but how you connect it to your home's electrical system is paramount for safety and effectiveness.
Crucial Point: Attaching a high-capacity dual fuel generator directly to your home's electrical system is not a DIY project. It requires professional installation of a manual transfer switch by a certified electrician.

What a Transfer Switch Does: It safely isolates your home's electrical system from the utility grid, preventing dangerous backfeeding that could injure utility workers or damage your generator. It also allows you to power specific circuits in your home directly from the generator.
Portable vs. Standby: While large portable dual fuel generators can power many essential circuits, they are generally not designed to power an entire home indefinitely. For whole-home, seamless backup, a permanently installed standby generator (which automatically kicks on when power goes out) is the typical solution. However, a robust portable dual fuel unit with a transfer switch provides excellent emergency coverage for most needs.
For smaller, more casual use, you can power individual appliances by plugging them directly into the generator's outlets using appropriate heavy-duty extension cords. Ensure cords are rated for outdoor use and have sufficient gauge for the appliance's power draw.

Keeping the Power Flowing: Maintenance & Lifespan

A generator is an investment that requires proper care to ensure it's ready when you need it most. Westinghouse generators are known for their durability, often coming with a three-year warranty and lifetime technical support.

Regular Exercise: Run your generator periodically (e.g., once a month for 20-30 minutes with a light load) to keep components lubricated and ensure it starts reliably.
Fuel Management:
Gasoline: Use a fuel stabilizer if you plan to store gasoline in the tank for more than a month. It's often recommended to run the generator until the fuel tank is empty before long-term storage to prevent carburetor issues from old fuel, or drain the fuel completely.
Propane: Propane stores indefinitely and burns cleaner, reducing fuel system maintenance.
Oil Changes: Follow the manufacturer's recommendations in the owner's manual for oil type and change intervals.
Air Filter & Spark Plug: Inspect and replace these components as needed.
Refueling Safety: Always turn off the generator and allow it to cool completely (at least 20 minutes) before adding fuel. Never refuel a hot or running generator.
Storage: Store your generator in a dry, protected area. Disconnect the battery if it has an electric start and store it in a cool, dry place.
A Note on Running Dry: While it might seem convenient, running a generator until it completely runs out of fuel can potentially damage the engine or attached electronics. It's better to shut it down manually before it sputters out.
When your generator reaches the end of its long service life, remember to dispose of it responsibly at a local recycling plant, as they contain hazardous materials.

Common Questions About Westinghouse Dual Fuel Generators

Can a Westinghouse dual fuel generator really power my whole house?

It depends on the size of your house and its power demands. The most powerful portable models, like the Westinghouse WGen12000DF, can provide substantial power for many essential circuits and even some large appliances.
