Buying Guide for the Best Natural Gas Generators

Choosing the right natural gas generator involves understanding your power needs and the specific features that will best meet those needs. Natural gas generators are a reliable source of backup power for homes and businesses, providing electricity during outages or in remote locations. To make an informed decision, you need to consider several key specifications that will determine the generator's performance, efficiency, and suitability for your particular situation.
Power Output (Wattage)Power output, measured in watts (W), indicates the amount of electricity the generator can produce. This is crucial because it determines whether the generator can handle the electrical load of your appliances and devices. Generators come in various power output ranges: small generators (up to 3,000 watts) are suitable for basic needs like lights and small appliances; medium generators (3,000 to 7,000 watts) can power multiple appliances and some larger devices; large generators (7,000 watts and above) can handle whole-house power needs or heavy-duty equipment. To choose the right one, list the essential devices you need to power and their wattage requirements, then select a generator that can comfortably handle that total load.
Fuel ConsumptionFuel consumption refers to how much natural gas the generator uses to produce electricity, typically measured in cubic feet per hour (cfh) or cubic meters per hour (m³/h). This is important because it affects the operating cost and efficiency of the generator. Lower fuel consumption means more efficient operation and lower running costs. To navigate this, compare the fuel consumption rates of different models under similar load conditions. Choose a generator that offers a good balance between power output and fuel efficiency, especially if you plan to use it frequently or for extended periods.
Run TimeRun time indicates how long the generator can operate on a full tank of fuel before needing a refill. This is crucial for planning how long you can rely on the generator during an outage. Run times can vary widely: some generators offer a few hours of operation, while others can run for 24 hours or more. To pick the right one, consider how long you typically need backup power. If you experience frequent or prolonged outages, a generator with a longer run time will be more convenient and reduce the need for frequent refueling.
Noise LevelNoise level, measured in decibels (dB), indicates how loud the generator will be during operation. This is important for comfort and compliance with local noise regulations. Generators can be quite noisy, with levels ranging from around 50 dB (similar to a quiet conversation) to over 100 dB (equivalent to a chainsaw). To navigate this, consider where you will place the generator and how close it will be to living or working areas. If noise is a concern, look for models specifically designed to operate quietly or consider installing soundproofing measures.
Start TypeStart type refers to how the generator is started, which can be manual (pull-start), electric (push-button), or automatic (starts automatically during a power outage). This is important for ease of use and convenience. Manual start generators are typically less expensive but require physical effort to start. Electric start generators are more convenient, especially for those who may have difficulty with pull-start mechanisms. Automatic start generators offer the highest level of convenience, as they can detect power outages and start without any user intervention. Choose the start type based on your preference for convenience and ease of use.
PortabilityPortability refers to how easy it is to move the generator. This is important if you need to transport the generator to different locations or store it when not in use. Portable generators typically have wheels and handles for easier movement, while stationary generators are designed to be installed in a fixed location. To pick the right one, consider how you plan to use the generator. If you need a generator for multiple locations or occasional use, a portable model will be more practical. For permanent backup power solutions, a stationary generator may be more suitable.
Maintenance RequirementsMaintenance requirements refer to the regular upkeep needed to keep the generator running smoothly. This includes tasks like oil changes, filter replacements, and general inspections. Maintenance is important for ensuring the longevity and reliability of the generator. Some models are designed to be low-maintenance, with features like automatic oil changes or self-diagnostics. To navigate this, consider how much time and effort you are willing to invest in maintenance. If you prefer minimal upkeep, look for models with low-maintenance features or consider a service plan.
