10 Best Natural Gas Home Generators 2025 in the United States

The Westinghouse 28000 Peak Watt Tri-Fuel Generator is a strong choice for homeowners needing a powerful backup power source, especially for larger homes. It offers impressive wattage, with up to 28,000 peak watts on gasoline and solid power even on natural gas (16,000 running watts), which is ideal for running multiple appliances during outages. Its tri-fuel capability (gasoline, propane, and natural gas) adds great flexibility depending on fuel availability, and the 17.2-gallon tank allows around 13 hours of runtime at a quarter load on gasoline, which is convenient for extended power needs.

The generator has a remote electric start and comes ready for an automatic transfer switch, making it easier to use during emergencies. It also protects sensitive electronics with clean power output, so you can safely run phones, computers, and TVs. While quite heavy at 557 pounds, it includes large, never-flat wheels and foldable handles that help with moving it around. The unit's maintenance is simplified by features like automatic low-oil shutdown and a digital display showing hours and voltage. Its size and weight mean it’s less portable than smaller models, which may be a consideration for some users.

This generator is well-suited for those who want reliable, high-capacity home backup power and are willing to accept its bulk in exchange for the power it delivers.

The Generac GP9500E TF is a powerful portable generator providing 9,500 running watts and 12,500 starting watts, making it suitable for home backup during outages and some commercial uses. One of its biggest advantages is the tri-fuel capability—it can run on gasoline, propane, or natural gas, offering flexibility depending on your fuel availability. The electric start makes it user-friendly, avoiding the hassle of manual pull-starts. With a 7.5-gallon tank, it runs about 9 hours at half load on gasoline, which is decent for extended power needs.

Durability is a strong point here: the unit has a rugged steel frame, covered outlets for protection, and never-flat wheels for easier movement, though at 219 pounds it’s still quite heavy and less portable than smaller models. The built-in COsense technology enhances safety by detecting dangerous carbon monoxide levels and shutting off the generator if needed.

This generator suits users who need reliable, flexible fuel options and strong power output for emergency or recreational use, and who can manage its size and maintenance needs. If quiet operation and automatic switching are priorities, you might want to explore other models.

The Generac 7225 14kW Air Cooled Guardian Series Home Standby Generator is a solid choice for those looking for reliable, whole-house power backup. With its 14,000 watt power output and Generac's True Power Technology, this generator ensures clean, stable power with less than 5% total harmonic distortion, which is ideal for safely running sensitive electronics. The 200-amp automatic transfer switch provides comprehensive protection by seamlessly switching power during outages, and the inclusion of Wi-Fi connectivity allows for remote monitoring and maintenance alerts, adding an extra layer of convenience and peace of mind. This feature is particularly useful for those who travel frequently or own multiple properties.

Additionally, the generator is designed with a durable aluminum enclosure and comes with a 5-year limited warranty, highlighting its long-term reliability and protection against the elements. It's also engineered and assembled in the USA, emphasizing quality craftsmanship.

However, there are some considerations to keep in mind. The generator is quite heavy at 385 pounds, which may limit portability and complicate installation, necessitating professional installation by a certified electrician. It's also worth noting that while the generator is designed to be relatively quiet, some noise is inevitable with any generator. The Generac 7225 is best suited for homeowners seeking a dependable and advanced generator with comprehensive monitoring features and robust power output, though it requires proper installation and has limitations in portability.
