Buying Guide: Key Considerations For Natural Gas Powered Generators
- Fuel flexibility: Tri-fuel generators offer natural gas, propane, and gasoline. Assess how easily you can access each fuel type at your home and in your area.
- Power requirements: Inventory your essential circuits and appliances. Choose a unit with enough running watts to cover the critical loads without hitting its limit.
- Run time and fuel tank: Look for tank capacity and run time at a practical load. Longer runtimes reduce refueling frequency during outages.
- Starting method: Electric start is convenient, but verify battery availability and maintenance needs. Manual recoil may be sufficient for some setups.
- Safety features: Carbon monoxide detectors, automatic low oil shutdown, and CO watchdog sensors improve safety during operation.
- Outlets and transfer switch readiness: Ensure the generator has outlets matching your transfer switch configuration and home circuits, including 30A/50A options when needed.
- Engine reliability and maintenance: Favor engines with durable components (e.g., cast iron sleeves) and accessible service intervals for long-term performance.
- Noise and portability: Inverter models generally run quieter and are easier to transport, but may have lower peak power than open-frame designs.
- Ventilation and placement: Always operate outdoors with clear airflow. Never run generators indoors or in enclosed spaces to avoid CO risks.
Frequently Asked Questions
What does tri-fuel mean for a generator?
Tri-fuel means the generator can run on gasoline, propane, and natural gas, offering fuel flexibility during outages or fuel supply variations.
Are natural gas generators safer for indoor use?
All portable generators should be operated outdoors in a well-ventilated area to avoid carbon monoxide hazards; never run indoors.
Is a higher running wattage always better?
Higher running wattage supports more appliances simultaneously, but you should match capacity to your essential loads to optimize fuel use and cost.
Do inverter generators work with home transfer switches?
Many inverter models offer transfer switch compatibility, but verify the specific receptacles and switch kits for your setup.
Can these generators be used with a home natural gas line?
Natural gas compatibility depends on model and local gas supply; professional installation is required to ensure proper gas pressure and safety.
What maintenance should I expect?
Regular oil changes, air filter checks, spark plug inspection, and battery upkeep for electric start models are common maintenance tasks.
