10 Best Natural Gas Home Generators 2025 in the United States

The Westinghouse 14500 Peak Watt Tri-Fuel Generator is a strong choice for homeowners looking for reliable backup power, especially for larger homes. It offers a high power output of up to 14,500 peak watts on gasoline, with slightly lower but still impressive wattage when running on propane or natural gas. This tri-fuel flexibility is a big plus, allowing you to choose among gasoline, propane, or natural gas depending on availability and convenience. It runs up to 19 hours on a full 9.5-gallon gasoline tank, which means it can last through a full night or day of outages, though propane runtime is shorter at around 7 hours.

The generator includes useful features like remote electric start and is ready for an automatic transfer switch, making it easier to use during emergencies. It’s also designed with safety in mind, including overload protection and a CO sensor. At 230 pounds and with a sturdy steel frame, it’s not very portable, so it’s best suited as a semi-permanent backup rather than something you’d move around frequently. Noise levels are typical for generators in this power range—not silent but manageable if placed a bit away from living areas.

Maintenance should be straightforward given the heavy-duty engine and included manuals, but it will require regular oil changes and fuel checks like any gas-powered generator. This Westinghouse model is well-suited for homeowners needing a powerful, flexible, and dependable backup power source, though its size and weight may limit portability if that’s a priority.

The Westinghouse 11000 Peak Watt Dual Fuel Generator is a strong choice for homeowners needing reliable backup power. It delivers a solid 9000 running watts on gasoline and 8100 watts on propane, enough to keep most household essentials running during outages. Its fuel tank holds 9.8 gallons and offers up to 17 hours of continuous operation, which is quite good for longer power needs. The dual fuel ability (gasoline and propane) adds flexibility depending on fuel availability.

This model includes a convenient remote electric start with a key fob, push-button, and recoil options, making it easy to operate from a distance or manually. Safety features like a built-in carbon monoxide (CO) sensor and automatic low oil shutdown help protect your home and the generator itself. It comes with a transfer switch ready outlet, so you can connect it directly to your home’s electrical panel for seamless power transfer during outages. The digital display provides useful info like fuel level and output, making monitoring straightforward.

It weighs over 180 pounds and measures about 30 x 25 x 27 inches, so it’s not very portable for one person and may require some effort to move around. Generators this size typically generate moderate noise, which might be noticeable in quieter neighborhoods. Maintenance is simplified with included tools and oil, but like all generators, regular servicing is necessary to keep it running smoothly. If you want a robust, versatile generator for home use with good safety and monitoring features, this Westinghouse model is worth considering, particularly if you value dual fuel options and easy start capabilities.

The DuroMax XP13000HXT stands out with a high power output of 13,000 watts, making it an excellent choice for keeping your entire home powered during outages. Its Tri-Fuel capability allows you to use gasoline, propane, or natural gas, offering flexibility based on availability. The 500cc engine ensures robust performance, and with the added CO Alert feature, it prioritizes safety by alerting you to harmful fumes.

The generator runs up to 8 hours, which is substantial for most needs. However, fuel consumption might vary depending on the type of fuel used, and it’s important to factor this in for longer outages. Noise levels are at 74 dB, which is relatively loud but typical for generators of this size. The inclusion of an Automatic Transfer Switch (ATS) compatible outlet simplifies integration with your home’s electrical system, although an ATS is not included.

Portability is enhanced with a wheel and handle kit, but at 240 pounds, it is still quite heavy and may require assistance to move. Maintenance is straightforward with provided tools and clear instructions, but regular upkeep is essential to ensure longevity. Push button and remote start features add convenience, but the generator’s size (30”L x 30”W x 26”H) might require dedicated storage space. This generator is best suited for homeowners needing substantial power and flexibility in fuel options and can also benefit small commercial setups.
