DuroMax XP13000EH Dual Fuel Portable Generator
The XP13000EH focuses on dual-fuel versatility (gasoline and propane) with an electric start for quick activation. While not explicitly listed as natural gas in all marketing materials, its dual-fuel architecture provides strong baseline performance and flexibility for many outage scenarios. It targets whole-home power needs with an emphasis on user-friendly operation and durable engine design.
Westinghouse 13500 Peak Watt Tri-Fuel Portable Generator
Westinghouse presents a 13500 peak watt, tri-fuel option with strong running watts across fuel types. This generator excels in backup power for mid-to-large homes, RVs, and job sites. Features include remote electric start, transfer-switch readiness, and CO-safe design. The engine is built for durability, and multiple outlets with rubber covers promote safety in various environments.
Westinghouse 13500 Peak Watt Tri-Fuel Portable Generator
This Westinghouse Tri-Fuel unit covers gasoline, propane, and natural gas with robust peak and running wattage figures. It delivers remote electric start and transfer-switch readiness, paired with multiple safety outlets and a high-capacity 500cc engine. The design emphasizes long runtimes on a large fuel tank and user-friendly operation for extended outages.
Buying Guide: Key Considerations For Natural Gas Portable Generators
- Fuel compatibility: Look for tri-fuel capabilities (gasoline, propane, natural gas) and ensure your natural gas line and home setup support continuous supply without backfeed risks.
- Power output and load management: Match running watts to essential circuits in your home or workspace. Consider surge/peak watts for starting appliances like air conditioners or well pumps.
- Transfer-switch readiness: If you plan to power whole-house circuits, choose models that are transfer-switch ready and ensure compatibility with your existing transfer panel.
- Safety features: CO shutoff sensors, low-oil shutdown, and protected outlets reduce risk during operation. CO monitoring is particularly important for indoor or semi-enclosed spaces.
- Run time and fuel tank: Larger tanks provide longer runtimes; evaluate expected outage durations and fuel availability in your area.
- Portability and durability: Wheel kits, rugged frames, and weather-resistant outlets help with transport and long-term use on job sites or yards.
- Noise considerations: Some tri-fuel models are louder; assess your property layout and neighbor considerations when selecting a unit.
- Maintenance and warranty: Check service support networks and warranty terms; tri-fuel models may require regular carburetor and fuel-system maintenance for long life.
- Safety installation: If wiring to a home, consult a licensed electrician and follow local electrical codes to prevent backfeeding or hazards.
- Future readiness: For long-term resilience, ensure the generator can perform enough wattage for planned upgrades (additional cooling, heating, or appliances).
