How to Choose Best Natural Gas Home Generators
Choosing the best Natural Gas Home Generators is a critical decision for your home’s security during a power outage. Natural gas generators connect directly to your home’s existing gas line, offering uninterrupted fuel flow—a major advantage over gasoline or propane during long-term emergencies. They eliminate the need for fuel storage, making them safer and more convenient. The right generator should meet your home’s maximum power draw while balancing factors like noise, fuel efficiency, and installation requirements.
Power Output (Wattage)
Power output determines how many appliances you can run simultaneously. For natural gas generators, power output is typically about 10–20% lower than running on gasoline, so check the specific natural gas wattage. Calculate the total wattage of all essential appliances you plan to run (e.g., HVAC, refrigerator, well pump) and choose a generator with at least 20% more running watts for a buffer. This is the most crucial step in choosing the best Natural Gas Home Generators.
Fuel Versatility (Tri-Fuel vs. Dual-Fuel)
While dedicated NG models exist, many of the best options are tri-fuel generators (gasoline, propane, and natural gas). Tri-fuel offers the ultimate redundancy: the convenience of natural gas with the backup options of propane or gasoline if the main gas line is compromised. Dual-fuel models (Gas/Propane) can be converted to NG but require an additional kit and professional installation, which adds complexity and cost.
Inverter vs. Conventional Technology
Inverter generators produce clean power with low Total Harmonic Distortion (THD), making them safe for sensitive electronics like computers and smart TVs. They are also significantly quieter and more fuel-efficient. Conventional generators are louder and often provide less clean power, but they are typically more affordable and available in higher wattage outputs for heavy loads like central air conditioning.
Safety and Start Features
Prioritize generators with modern CO Shutdown Sensors (like CO Alert or COsense), which automatically turn off the engine if carbon monoxide builds up. Also, look for an electric start (push-button or remote fob) to ensure the generator can be reliably and easily started, which is a major convenience in an emergency. Low-oil shutdown protection is also vital for engine longevity.
Transfer Switch Readiness
For home backup, the generator should have a high-amperage outlet (e.g., NEMA L14-30R or NEMA 14-50R). These outlets allow for a direct, safe connection to a manual transfer switch or interlock kit, which is necessary to power your home’s circuits directly from the generator panel and avoid the dangerous practice of back-feeding. Always consult a licensed electrician for installation.
Natural Gas Home Generator Maintenance
Unlike gasoline generators, which require fuel stabilization and carburetor draining, natural gas models simplify long-term storage and maintenance because the fuel is always fresh and readily available. However, all generators, including the Best Natural Gas Home Generators, still require regular maintenance to ensure peak performance when an emergency strikes. Annual maintenance should include checking the oil level, air filter, and spark plugs. Ensure the battery for the electric start is charged and functional.
An important element is the load test. You should start your natural gas generator and run it under a partial load for 30 minutes every 1–3 months. This keeps the engine lubricated, recharges the battery, and confirms that all systems are operational. Also, regularly inspect the natural gas connection hose and fittings for any signs of wear or leakage, following all manufacturer instructions and local gas generator regulations.
How to Use Best Natural Gas Home Generators
Using the best Natural Gas Home Generators correctly involves proper setup and adherence to safety protocols.
- Step 1: Setup/Prep: First, ensure the generator is placed outdoors, at least 20 feet away from any windows, doors, or vents to prevent carbon monoxide poisoning. Connect the natural gas hose from your home’s quick-connect fitting to the generator’s fuel inlet. Check the oil level and confirm the battery for the electric start is connected.
- Step 2: Core Usage & Best Practices: Turn the fuel selector dial to the “Natural Gas” setting. If your model has a choke, apply it as needed (less in warm weather). Use the electric or remote start button to power the unit on. Once the engine is running and stabilized, you can connect your transfer switch cable and flip the necessary circuit breakers on your transfer panel to restore power to your home.
- Step 3: Optimization/Safety/Maintenance: Avoid overloading the generator. Monitor the power panel display if available to ensure you stay below the rated running wattage. If running a few hours, periodically check the oil level. After the utility power is restored, disconnect the generator from the transfer switch before turning off the engine.
- Step 4: Troubleshooting & Pro Tips: If the generator won’t start, check the fuel selector (ensure it’s on NG), confirm the engine is not low on oil, and try using the pull-cord backup start. If the power output suddenly drops, check for an overload condition and switch off unnecessary appliances. Always allow the generator to cool completely before covering it or moving it.
Frequently Asked Questions
Can I run my natural gas generator continuously?
Yes, one of the biggest benefits of a natural gas connection is the ability to run the generator for days or even weeks because the fuel supply is essentially limitless. This is a primary reason why people invest in the best Natural Gas Home Generators for long-term backup. However, it’s critical to monitor the oil level and follow the manufacturer’s recommended maintenance intervals.
Is a natural gas generator less powerful than a gasoline generator?
Generally, yes. Natural gas has a lower energy density than gasoline, resulting in a 10% to 20% reduction in power output for the same engine. When comparing models, always check the specific running wattage listed for natural gas to ensure it meets your needs, especially when looking for the best Natural Gas Home Generators in terms of output.
Do portable natural gas generators need professional installation?
Yes. While the generator unit is portable, the natural gas connection to your home’s main gas line must be installed by a licensed plumber or HVAC technician. They ensure the connection is safe, meets local codes, and that the gas pressure is sufficient to run the generator reliably.
Are natural gas generators safer than gasoline generators?
In terms of fuel handling, natural gas is significantly safer as there is no need to store flammable liquid fuel in containers. However, the risk of carbon monoxide poisoning remains. Therefore, all generators, especially the best Natural Gas Home Generators, must be operated exclusively outdoors and away from the home.
What size natural gas line do I need for my generator?
The required gas line size (diameter) depends on the BTU consumption of your generator and the distance from the gas meter. Running too small a line will cause the generator to starve for fuel and fail under load. This is a critical detail that an HVAC professional must calculate before installation.
Final Thoughts
Choosing among the best Natural Gas Home Generators means investing in unparalleled convenience and long-term security. The ability to connect directly to an infinite fuel source and avoid panic-buying fuel during a major storm is a priceless benefit. The key considerations should always be the specific natural gas running wattage to match your home’s needs and the inclusion of modern safety features like the CO shutdown sensor.
For most buyers seeking a perfect balance of power and high-end features, the Westinghouse iGen8200TFc Tri-Fuel Inverter Generator offers the best of both worlds, providing clean, quiet power and 50A transfer switch readiness. If, however, you require maximum raw power for a large home with central HVAC and heavy loads, choose the Westinghouse 14500 Peak Watt Tri-Fuel Generator for its robust 9,500 running watts on natural gas.
