Complete Buyer's Guide: How to Choose Natural Gas Generator for Home Backup

1. Determine Your Power Requirements

Start by calculating the total wattage needed for essential appliances during an outage. Consider both running watts and the higher starting watts required for motors in refrigerators, air conditioners, and well pumps.

Most homes need between 5,000 and 10,000 watts for basic functionality, but larger homes with central air may require 12,000 watts or more.

2. Understand Natural Gas vs Other Fuel Types

Natural gas offers convenience since it’s supplied through utility lines, meaning you never run out during extended outages. However, wattage output is typically 10-20% lower than gasoline.

Tri-fuel generators provide the ultimate flexibility, allowing you to switch between natural gas, propane, and gasoline based on availability and cost.

3. Consider Inverter vs Conventional Generators

Inverter generators produce cleaner, more stable power that’s safe for sensitive electronics like computers, TVs, and medical equipment. They’re also quieter and more fuel-efficient.

Conventional generators offer higher wattage at lower cost but may produce power that can damage electronics without additional protection.

4. Evaluate Safety Features

Look for generators with CO detection technology that automatically shuts down the unit if dangerous carbon monoxide levels are detected. This is crucial for home safety.

Other important features include low oil shutdown, overload protection, and covered outlets for weather resistance.

5. Plan for Installation and Transfer

For whole-home backup, you’ll need a transfer switch installed by a qualified electrician. This prevents backfeeding into utility lines and protects utility workers.

Consider the generator’s placement – it should be at least 20 feet from your home with proper ventilation to prevent CO buildup.

6. Assess Runtime and Maintenance Needs

Natural gas generators can run indefinitely since they’re connected to utility lines, while gasoline and propane have limited tank capacity.

Regular maintenance includes oil changes, air filter cleaning, and occasional spark plug replacement to ensure reliability when you need it most.

Frequently Asked Questions

1. How long can a natural gas generator run continuously?

Natural gas generators connected to utility lines can run indefinitely during outages, unlike gasoline or propane models that are limited by fuel tank capacity. However, you should still follow manufacturer recommendations for maintenance intervals and occasional cool-down periods.

2. Do I need an electrician to install a natural gas generator?

Yes, professional installation is strongly recommended for natural gas generators. You’ll need both a licensed plumber to connect the gas line and a qualified electrician to install the transfer switch and electrical connections. This ensures safety and compliance with local codes.

3. What's the difference between running watts and starting watts?

Running watts are the continuous power needed to keep appliances operating, while starting watts are the extra burst required to start motors in devices like refrigerators and air conditioners. Starting watts are typically 2-3 times higher than running watts, so your generator must accommodate both.

4. Can I run my entire house on a natural gas generator?

Most homes can run essential circuits on generators between 7,000-12,000 watts, but whole-house coverage for larger homes may require 15,000 watts or more. You’ll need to prioritize circuits and may not be able to run every appliance simultaneously during an outage.

5. How loud are natural gas generators?

Natural gas generators typically produce 65-80 decibels at full load, which is similar to a lawn mower or vacuum cleaner. Inverter models are generally quieter (65-75 dB) than conventional open-frame generators (70-80 dB). Proper placement and sound-dampening enclosures can help reduce noise.

Final Verdict

After extensive testing and analysis, the Westinghouse 14500 Peak Watt Tri-Fuel Generator emerges as our top choice for most homeowners seeking reliable natural gas backup power. It combines substantial output with crucial fuel flexibility and modern features like remote start. For those prioritizing clean power for electronics, the Westinghouse iGen11000TFc Inverter Generator offers exceptional performance, while budget-conscious shoppers will appreciate the WEN TF1450X with its valuable CO safety feature at an accessible price point. Remember that proper installation and regular maintenance are just as important as choosing the right generator – your family’s safety and comfort during outages depend on it.
