Westinghouse Tri-Fuel Home Backup Generator vs DuroMax XP17500HX Generator

The Westinghouse is the bigger machine: 20,000 running watts on gasoline and tri-fuel support that adds natural gas, so it can run a large home's central air and well pump off a plumbed gas line. The DuroMax XP17500HX makes 13,750 running watts on gas and 13,000 on propane, weighs roughly half as much, and adds CO Alert shutdown, a wireless remote and a five-year warranty. Buy the Westinghouse for whole-home backup on natural gas or the largest loads; buy the DuroMax for a transfer-switch setup where portability, safety shutdown and warranty length matter more than raw output.

• Choose the Westinghouse if you need maximum running watts, natural gas as a third fuel, or enough power for a large home's central air and electric heat.
• Choose the DuroMax if you want a lighter, easier-to-move unit with CO Alert shutdown, remote start and a five-year warranty for a transfer-switch or interlock install.
