It features electric start, aiding quick and easy startup after outages, and a design tuned for home backup and RV use. The unit emphasizes durability with a robust frame and typical Generac reliability, suitable for longer outages and job-site scenarios where fuel types differ.
Westinghouse 14500 Peak Watt Tri-Fuel
Westinghouse’s 14500 Peak Watt tri-fuel generator targets larger homes with greater backup capacity. It delivers 11,500 running watts on gasoline, 13,500 peak, and scales to 10,500 running watts with propane or 9,500 running watts with natural gas. The engine is a heavy-duty 550cc 4-stroke OHV, designed for long runtimes and extended outages. With up to 19 hours of runtime on a 9.5-gallon tank and a built-in fuel gauge, this model is positioned for serious power needs during emergencies.
Westinghouse 12500 Watt Dual Fuel
This Westinghouse model mirrors the 12500 Peak Watt dual-fuel capabilities, with 9,500 running watts on gasoline and 8,500 on propane, plus 12,500 peak on gasoline and 11,200 peak on propane. Features include remote electric start, a 6.6-gallon fuel tank with gauge, and a set of transfer switch-ready outlets: two 20A GFCI outlets, a 30A transfer switch, and an RV-ready 50A outlet. It uses a 457cc engine with automatic low-oil shutdown and a digital hour meter for maintenance tracking.
Westinghouse 12500 Peak Watt Tri-Fuel
Designed for multi-fuel flexibility, this tri-fuel unit can run on gasoline, propane, or natural gas, offering 12,500 peak watts and 9,500 running watts on gasoline. Propane delivers 11,200 peak and 8,500 running watts, while natural gas provides 12,000 peak and 9,500 running watts. It includes remote start with a key fob, a 6.6-gallon tank with gauge, and a full complement of outlets—GFCI, transfer-ready, and RV connections. The engine is a heavy-duty 457cc Westinghouse 4-stroke OHV with safety shutoffs and a digital hour meter.
Buying Guide: Key Purchase Considerations
Power needs: Calculate starting watts and running watts for essential circuits (refrigerator, furnace, sump pump, lights, electronics). For larger homes, tri-fuel models offer fuel flexibility during shortages, but they are heavier and more expensive.
Fuel options: Dual-fuel and tri-fuel units add versatility. Propane, natural gas, and gasoline each have trade-offs in cost, availability, and energy density. Consider fuel storage and shelf life for your typical outage duration.
Starting method: Electric start with a battery provides quick starts, especially in cold weather. Recoil (manual) starts are more rugged but can be challenging if the battery is dead or you’re dealing with inclimate conditions.
Transfer switch readiness: A transfer switch-ready generator simplifies installation and automatic power transfer to circuits during outages. Ensure compatibility with your home panel and consult a licensed electrician for installation.
Runtime and fuel tank: Look for run time at a practical load (25–50%) and the tank size. Longer runtimes reduce refueling frequency during outages. Noise levels and engine design also affect suitability for residential use.
Outlets and safety: Multiple GFCI outlets, RV-ready outlets, and CO shutoff enhance safety. A digital hour meter helps with maintenance planning, while a robust engine and cast-iron sleeves indicate durability.
Mobility and maintenance: While many generators are portable, weight and wheel kits influence placement during a storm. Maintenance features such as oil shutdown, air filters, and carburetor cleanliness prolong life and reliability.
Warranty and support: Consider brand reputation, warranty length, and access to service centers. Generac, Westinghouse, and DuroMax offer broad support networks, which can matter during post-outage readiness.
