Fuel Flexibility
The Westinghouse 13500W Tri-Fuel Portable Generator supports three fuel sources: gasoline, propane, and natural gas. It offers 10,000 peak watts and 8,500 running watts when running on natural gas. The Westinghouse 14500W Dual Fuel Portable Generator only supports gasoline and propane. It does not list natural gas compatibility in its specifications. If you have access to a natural gas line for backup power, the 13500W Tri-Fuel model provides more versatility.
Engine Size
The Westinghouse 14500W Dual Fuel Portable Generator is powered by a 550cc 4-Stroke OHV engine. The Westinghouse 13500W Tri-Fuel Portable Generator uses a slightly smaller 500cc 4-Stroke OHV engine. Both engines feature a cast iron sleeve for durability. The 550cc engine in the 14500W model may provide more torque to handle the higher wattage output, although both are described as heavy-duty units designed for home backup.
Dimensions
Both generators weigh 230 pounds, but their physical footprints differ. The Westinghouse 14500W Dual Fuel Portable Generator is larger, measuring 29.6 inches in width, 28.9 inches in length, and 26.9 inches in height. The Westinghouse 13500W Tri-Fuel Portable Generator is more compact at 26.1 inches wide, 27.2 inches long, and 26.5 inches high. If storage space is limited in your garage or shed, the 13500W Tri-Fuel model takes up less room.
Safety Features
The Westinghouse 13500W Tri-Fuel Portable Generator includes an Automatic Low Oil and Carbon Monoxide (CO) Shutdown system. Its specifications explicitly list a CO sensor as part of the unit's size description. The Westinghouse 14500W Dual Fuel Portable Generator description mentions low THD for sensitive electronics and durable copper windings, but it does not explicitly list a CO sensor or automatic shutdown in the provided data. For safety monitoring, the 13500W model has the documented advantage.
