10 Best Natural Gas Home Generators 2026 in the United States

The DuroMax XP16000iHT is a powerful tri-fuel generator designed to provide reliable whole-home backup power with a maximum starting wattage of 16,000 and running wattage of 13,000. Its ability to run on gasoline, propane, or natural gas offers great flexibility, making it a solid choice if you want to keep your generator running during fuel shortages or preference changes. The 10.5-gallon tank and fuel efficiency enable up to 18 hours of runtime, which is convenient for extended outages. It includes dual 50-amp outlets for easy connection to a transfer switch, allowing seamless backup integration with your home’s electrical system.

The remote electric start adds comfort by letting you operate the generator from inside your home, especially useful during storms. Safety is enhanced by a built-in carbon monoxide sensor that shuts off the unit if dangerous levels are detected. The inverter technology ensures quieter operation and clean power, safe for sensitive electronics. However, at 505 pounds and large dimensions, it is not very portable and will require a dedicated spot for installation. Also, while it is transfer switch ready, the transfer switch itself is not included, which means additional installation cost.

Maintenance-wise, the heavy-duty 4-stroke engine is built for durability but will require regular upkeep like any gas engine. Noise levels are relatively low for its size, but it’s still louder than smaller home generators. This DuroMax model is a strong option if you need a high-capacity, flexible-fuel generator for whole-home backup and are prepared to manage its size and maintenance requirements.

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.
