Frequently Asked Questions About Backup Natural Gas Generators and Propane Generators
We know you have questions about standby natural gas generators for sale and propane-powered generators. Here are the answers to some of the most common ones.
How Do These Generators Work?
Natural gas and liquid propane generators convert fuel into electrical power through a complex process involving several key components. They use natural gas or propane as fuel, which is drawn either from a direct line piped in by utility suppliers or via a tank. This fuel then powers an internal combustion engine, which injects a mixture of fuel and air into a combustion chamber. A spark plug ignites this mixture, creating mechanical energy that is converted into electricity.
Can I Install a Generator Myself?
While self-installation of your standby natural gas or propane generators is possible, it is strongly recommended to opt for professional installation. This ensures the generator is set up safely and efficiently, minimizing risks associated with improper installation, such as safety hazards or reduced efficiency of the unit.
Which Is More Fuel-Efficient, Natural Gas or Propane?
Both natural gas and propane are efficient fuel sources for generators. However, propane is noted to have a slightly higher energy content per cubic foot, making it a bit more efficient in terms of energy output.
What size standby generator does my business need?
Sizing a commercial or industrial standby generator depends on your facility's total electrical load and which circuits need backup power. Small commercial buildings and restaurants are often covered by units in the 25 to 60 kW range, while larger facilities may require 100 kW or more. PDG's team can review your load requirements and recommend the right propane or natural gas generator for your facility, contact us for a free sizing consultation.
What Are the Benefits of Choosing Backup Natural Gas and Propane Generators?
Opting for standby natural gas generators for home or commercial use or propane backup generators presents multiple advantages, including cleaner energy production with lower emissions, lower operating costs compared to diesel or gasoline generators, and high reliability during power outages. LP generators are noted for their environmental friendliness, being recognized as an "approved clean fuel" by the 1990 Clean Air Act due to their low carbon emissions. For commercial and industrial facilities, these lower operating costs and reduced maintenance requirements translate directly into lower total cost of ownership across a fleet of standby units.
What Maintenance Do These Generators Require?
Regular maintenance, including inspections, oil changes, and filter replacements, is essential for propane and natural gas generators to operate smoothly. Ensuring these tasks are performed routinely will help maintain the efficiency and longevity of the generator, keeping it ready for use when needed.
How Do I Decide Between Natural Gas and Propane?
Choosing between a stationary natural gas and propane generator involves considering fuel availability in your area, storage options, and your specific power requirements. Propane offers greater portability and storage benefits, making it an excellent choice for areas without direct natural gas supply, whereas natural gas might be more convenient where a direct supply is available.
