Westinghouse’s 12500-watt dual-fuel unit combines long runtime with robust outlets, including transfer switch readiness and RV compatibility. It supports electric and recoil start options for flexibility and provides an extended runtime on a sizable fuel tank. The unit’s design emphasizes safety with rubber-covered outlets and a digital hour meter to help track maintenance and fuel efficiency during outages.
Westinghouse 13500 Peak Watt Tri-Fuel Generator
This Westinghouse model covers a broad power range with 13500 peak watts and triangle fuel capability. It features remote electric start and transfer switch readiness, with a long-running fuel tank and a CO-safety system. The design emphasizes reliability for larger households or job sites, offering substantial power for running multiple circuits and heavy appliances during outages.
Westinghouse 13500 Peak Watt Tri-Fuel Backup Generator
Westinghouse’ 13500 Peak Watt Tri-Fuel unit provides substantial power with gas, propane, and natural gas options. It includes remote starting, multiple outlet configurations, and a high-capacity engine with safety features like automatic low oil shutdown and a CO detector. It is built for long runtimes and dependable performance under varied outage scenarios, including larger homes or remote work environments.
Buying Guide
When choosing a portable tri-fuel generator that can run on natural gas, consider these factors:
- Fuel flexibility and availability: Tri-fuel models offer gasoline, propane, and natural gas. Assess which fuel is most accessible for your location and typical usage patterns.
- Power output needs: Compare peak and running watts to ensure your essential appliances and circuits have enough headroom. For larger homes, prioritize higher running watts and multiple outlets.
- Starting method: Electric start improves usability, especially in cold or outage conditions. Some models also offer recoil or remote start options for convenience.
- Safety features: CO shutdown (CO detector), automatic low-oil shutdown, and covered outlets reduce risk during use outdoors and in confined spaces.
- Transfer switch readiness: If you plan to connect to a home transfer switch, verify compatibility with your panel and surge protection.
- Runtime and fuel capacity: Look for larger fuel tanks and efficient engines to maximize runtime at a given load, particularly when running multiple appliances.
- Noise and emission considerations: Larger units can be louder; check “quiet operation” claims and local noise regulations if you plan to use them at campgrounds or neighborhoods.
Practical guidance for selection: If you need power for a whole-home backup during outages, prioritize higher running watts, reliable tri-fuel capability, and a robust safety system. For RVs or job sites, check transfer-switch compatibility, outlet configurations, and portability features like wheels and handles. Always follow manufacturer guidelines for proper fueling, ventilation, and maintenance to maximize safety and efficiency.
