The DuroMax XP13000HXT stands out with a high power output of 13,000 watts, making it an excellent choice for keeping your entire home powered during outages. Its Tri-Fuel capability allows you to use gasoline, propane, or natural gas, offering flexibility based on availability. The 500cc engine ensures robust performance, and with the added CO Alert feature, it prioritizes safety by alerting you to harmful fumes.

The generator runs up to 8 hours, which is substantial for most needs. However, fuel consumption might vary depending on the type of fuel used, and it’s important to factor this in for longer outages. Noise levels are at 74 dB, which is relatively loud but typical for generators of this size. The inclusion of an Automatic Transfer Switch (ATS) compatible outlet simplifies integration with your home’s electrical system, although an ATS is not included.

Portability is enhanced with a wheel and handle kit, but at 240 pounds, it is still quite heavy and may require assistance to move. Maintenance is straightforward with provided tools and clear instructions, but regular upkeep is essential to ensure longevity. Push button and remote start features add convenience, but the generator’s size (30”L x 30”W x 26”H) might require dedicated storage space. This generator is best suited for homeowners needing substantial power and flexibility in fuel options and can also benefit small commercial setups.

Buying Guide for the Best Natural Gas Home Generators

Choosing the right natural gas home generator involves understanding your power needs and the features that will best serve your household. Natural gas generators are a reliable source of backup power during outages, and selecting the right one ensures that your home remains functional and safe. Here are the key specifications to consider when making your decision.
Power Output (Wattage)Power output, measured in watts, indicates how much electricity the generator can produce. This is crucial because it determines how many and what type of appliances you can run simultaneously. Generators typically range from 5,000 to 20,000 watts. For small homes or essential circuits, a lower wattage may suffice. Larger homes or those with high power demands will need higher wattage. Assess your household's power needs by listing essential appliances and their wattage requirements to guide your choice.
Fuel ConsumptionFuel consumption refers to how much natural gas the generator uses over a specific period, usually measured in cubic feet per hour (cfh). This is important for understanding the operational cost and ensuring you have a sufficient gas supply. Generators with lower fuel consumption are more efficient and cost-effective over time. Consider your natural gas supply and how long you need the generator to run when evaluating this spec.
Run TimeRun time indicates how long the generator can operate continuously on a full fuel supply. This is important for planning during extended power outages. Generators with longer run times are beneficial for areas prone to frequent or prolonged outages. Choose a generator with a run time that matches your typical outage duration and your comfort level for refueling or maintenance.
Noise LevelNoise level, measured in decibels (dB), indicates how loud the generator will be during operation. This is important for maintaining a comfortable living environment and adhering to local noise regulations. Generators typically range from 50 to 70 dB. If you live in a densely populated area or value peace and quiet, opt for a generator with a lower noise level. Consider where the generator will be placed and how noise might affect you and your neighbors.
Automatic Transfer Switch (ATS)An Automatic Transfer Switch (ATS) allows the generator to automatically switch on during a power outage and off when power is restored. This is important for convenience and ensuring continuous power without manual intervention. If you prefer a hands-off approach and want to ensure critical appliances are always powered, choose a generator with an ATS. Evaluate your comfort with manual operation versus the convenience of automatic switching.
Size and PortabilitySize and portability refer to the physical dimensions and ease of moving the generator. This is important for installation space and potential relocation needs. Larger generators typically offer more power but require more space and may be stationary. Smaller, portable generators are easier to move but may offer less power. Consider where you will place the generator and if you need to move it frequently when making your choice.
Maintenance RequirementsMaintenance requirements include the frequency and type of upkeep needed to keep the generator running smoothly. This is important for ensuring long-term reliability and performance. Some generators require regular oil changes, filter replacements, and inspections. Choose a generator with maintenance requirements that match your ability to perform or arrange for these tasks. Consider your willingness and ability to maintain the generator when evaluating this spec.
