The backup power can support home essentials during outages, and a 9.5-gallon tank supports extended operation between refuels. It includes a transfer switch-ready output and safety features like rubber-coated outlets for weather-resistant use.
Westinghouse 12500 Watt Dual Fuel
This unit combines dual fuel versatility with robust power for mid-sized homes or work sites. It supports gas and propane with a 6.6-gallon fuel tank and a fuel gauge for monitoring. A VFT display provides real-time voltage, frequency, and lifetime hours information, aiding maintenance and reliability. It includes multiple outlets and a transfer switch-ready configuration, enhancing integration with home circuits.
DuroStar 13,000-Watt Dual Fuel
With 13,000 watts, this DuroStar model targets whole-home backup and RV-ready use. It supports dual fuel (gasoline and propane) with CO alert features to enhance safety. Remote electric start improves convenience, particularly during adverse weather. The unit is designed to be transfer-switch ready, enabling seamless connection to residential circuits for reliable power when the grid is down.
DuroMax XP13000EH
The XP13000EH is a robust dual-fuel option designed for whole-home backup or remote job sites. It blends high surge wattage with dual fuel flexibility, offering electric start for quick powering up after outages. While primarily gas/propane, its design supports reliable operation under heavy load and includes transfer switch compatibility to integrate with home electrical systems efficiently.
Buying Guide: Key Considerations For Dual Fuel Generators And Natural Gas
- Fuel flexibility: Models with natural gas compatibility can be slower to start and produce different wattage compared to gasoline. Consider a unit that clearly lists running and surge watts for each fuel type.
- Transfer switch readiness: If you plan to power essential circuits during outages, choose a generator with a transfer switch-ready outlet and compatible L14-30 or RV outlets.
- Power balance: Evaluate whether you need full-house backup (high wattage) or partial support (critical circuits only). Higher peak watts help with motor-start loads like ACs but require larger fuel tanks.
- Safety features: CO sensors, automatic shutoffs, rubber-coated outlets, and overload protection reduce risk in residential use. Consider units with CO watchdog or CO alert features.
- Starting mechanism: Electric start is convenient, but ensure you have battery maintenance and a backup recoil start as a secondary option in power outages.
- Runtime and fuel capacity: Larger fuel tanks extend operation but add weight and size. Compare tank capacity, engine efficiency, and expected runtime at typical loads.
- Portability vs. capacity: If you need frequent transport, lighter models with wheels and ergonomic handles are advantageous, but they may offer less fuel capacity and lower peak watts.
- Noise and emissions: Look for models with emissions-compliant engines and design features that reduce noise to minimize neighborhood disturbance during outages.
- Warranty and service: A solid warranty and accessible service centers help for long-term maintenance and peace of mind during emergencies.
- Installation safety: If connecting to a transfer switch, ensure professional installation in accordance with local electrical codes and manufacturer guidelines.
